Hippocrates of Cos
Hippocrates of Cos (c. 460 - c. 370 BCE) is the most famous name in the history of Western medicine and one of the least well-known as an actual person. Almost nothing that can be verified survives about the historical Hippocrates. The vast body of writings attributed to him — the Hippocratic Corpus — was composed by many different authors over more than a century, and the doctrines most closely associated with his name, including the four-humour theory, were almost certainly not his. What made Hippocrates matter was not what he wrote but what later generations made of him: a symbol of rational medicine, an authority to be claimed, and a legend powerful enough to shape the profession for two thousand years.
The Historical Hippocrates
The evidence for the real Hippocrates is thin. An epitaph preserved in the biographical tradition describes him as Thessalian, Coan by descent, born of Apollo’s race — a formulation that bundles together the places he lived, the island from which his family came, and the divine ancestry that the Asclepiad guild claimed.(Pormann (ed.), 2018) Where multiple late biographical traditions happen to agree on the same detail, Craik argues, this coincidence corroborates some salient points: born in Cos, resident in Thessaly, in a special relationship with the healing gods, a successful physician.(Pormann (ed.), 2018) (Pormann (ed.), 2018) Beyond these points, extreme scepticism about ancient biographical data is the dominant scholarly mood.(Pormann (ed.), 2018) The difficulty is not peculiar to Hippocrates: many major Greek intellectual figures of the fifth century are no less elusive, their lives equally dependent on late and unreliable sources.(Pormann (ed.), 2018)
Plato, writing within a generation, confirms in the Protagoras that Hippocrates came from Cos, was an Asclepiad (a member of a family claiming descent from the healing god Asclepius), enjoyed a reputation comparable to the greatest sculptors of his age, and was teaching medicine for money (Nutton, 2023). Jouanna’s modern philological survey opens from this same passage and reads it as the firm anchor of the historical record: in the Protagoras, Socrates puts Hippocrates of Cos forward as the textbook example of a paradigmatic physician, parallel to Polyclitus of Argos and Phidias of Athens as paradigmatic sculptors, and the dialogue (set around 430 BCE) attests that by the end of the fifth century Hippocrates was already known for his teaching and regarded by his contemporaries as the most celebrated physician of the Periclean Age (Jouanna, 1999). The contemporary use of the formula “Hippocrates of Cos, the Asclepiad” was, on Jouanna’s reading, a working name needed to distinguish him from others who carried what was a common Greek name (Jouanna, 1999). Pormann and Craik note that Plato and Aristotle were both contemporaries who allude to Hippocrates as a prominent figure — Aristotle confirming that he was born around 460 BCE, was short in stature, charged for teaching medicine, and was well known before his death (Pormann (ed.), 2018). In the Phaedrus, Plato alludes to a passage where Hippocrates stated that one cannot know the nature of the body without knowing the nature of the whole — a claim much discussed by later commentators, but one that is not a literal quotation from any text in the surviving Corpus (Pormann (ed.), 2018). This basic outline is confirmed by Henry Sigerist, who notes that Plato is the only contemporary who named Hippocrates, and that what is certain is simply that he lived, was a famous practitioner and teacher, came from Cos, and belonged to the Asklepiad guild (Henry E. Sigerist, 1933). Aristotle, a generation later, attributed The Nature of Man — the text that articulated the four-humour theory — not to Hippocrates but to his pupil and son-in-law Polybus (Nutton, 2023). The Anonymus Londinensis papyrus, drawing on a medical doxography compiled by Aristotle’s pupil Meno, attributed to Hippocrates a completely different theory based on residues and breaths, not humours at all (Nutton, 2023).
Almost nothing is known of the historical Hippocrates (Nutton, 2023). He is unlikely to have devised the Hippocratic Oath, and several passages in the Corpus describe practices that would violate it (Nutton, 2023). Yet Craik argues against abandoning the notion of Hippocrates entirely: the long tradition saw a unifying principle binding the various texts together, and the texts cannot be fully separated from the historical figure who marks the beginning of the Hippocratic tradition.(Pormann (ed.), 2018) As Hippocrates’ fame grew through the centuries, more and more apocryphal stories accumulated: he cured a Persian king of lovesickness, refused a high salary to go to the Persian court, and cured the Athenian plague.(Pormann (ed.), 2018)
Plato returned to Hippocrates in the more mature Phaedrus, where Socrates and Phaedrus invoke “Hippocrates of the Asclepiad family” as an authority on method, asserting that one cannot satisfactorily comprehend the nature of the soul (or even the body) apart from the nature of the universe and that the right procedure is the one Hippocrates prescribes (Jouanna, 1999). Jouanna reads this passage as evidence that Hippocrates’ teaching was known in detail in Athens, even though he had never lived or taught there, and as a sign of the broader influence of medical thinking on the intellectual history of classical Greece, with a philosopher invoking a physician and the science of the body serving as a model for the science of the soul (Jouanna, 1999). Forty years later, Aristotle, the son of a doctor and a recommender of medical study to philosophers, continued to use Hippocrates as a stock example, citing him in the Politics as a man great by reason of his science rather than his stature (Jouanna, 1999); by Aristotle’s time the bare name “Hippocrates” was sufficient to identify the physician of Cos, without the further qualifications that had been needed in Plato’s day (Jouanna, 1999).
There is one other fifth-century witness, of a different kind. Aristophanes appears to parody the physicians’ Oath in one of his comedies, suggesting that Hippocratic practices were already familiar enough in Athens to serve as material for comic allusion.(Pormann (ed.), 2018) This would make the comedies a form of independent attestation for the social presence of Hippocratic medicine in the classical city, even if Hippocrates himself never lived there.
The biographical record beyond Plato and Aristotle is largely a matter of source criticism. Aristophanes’ Thesmophoriazusae uses the phrase “household of Hippocrates,” which nineteenth-century scholarship interpreted as an allusion to the medical brotherhood; Jouanna shows the reference is in fact to the foolish sons of an Athenian general also called Hippocrates, a nephew of Pericles who had been ridiculed in Clouds (Jouanna, 1999). The pseudo-Hippocratic Letters date from the Roman era (between the first century BCE and the first century CE), and on Jouanna’s reading the events and opinions they attribute to Hippocrates are highly suspect, although individual passages may preserve genuine ancient traditions now otherwise lost (Jouanna, 1999). The Presbeutikos (Speech of the Envoy), attributed to Hippocrates’ son Thessalus and supposed to have been delivered before the Athenian assembly at the end of the fifth century, contains specific details about the First Sacred War and the First Persian War that have been confirmed by recent epigraphic discoveries, lending it more weight as a source than the rest of the epistolary literature (Jouanna, 1999). The canonical biography is the Life of Hippocrates attributed to Soranus of Ephesus, which heads the manuscripts and earliest editions of the Hippocratic works and draws on more ancient sources, the most important being the Hellenistic library director Eratosthenes of Cyrene (Jouanna, 1999). A local Coan scholar, also called Soranus, consulted the island’s archives and recorded that Hippocrates was born in 460 BCE (the first year of the Eighty-Fourth Olympiad) on the twenty-seventh day of the Dorian month Agrianos, under the “monarchy” of Abriadas (Jouanna, 1999).
A traveler today who lands at the modern town of Cos and admires the great platan tree in the Plateia Platanou where Hippocrates is conventionally said to have taught is, on Jouanna’s deflationary reading, looking at a tree that is at most five centuries old, younger than Hippocrates by about twenty centuries (Jouanna, 1999). The bald-headed bust in the museum at Cos that the Blue Guide tentatively identifies as a Hellenistic copy of a classical original of Hippocrates is also, on Jouanna’s account, certainly a false attribution, since the long-haired statue does not match the bald-headed Hippocrates pictured on Roman-period coins of Cos and authenticated by the abbreviation III (Jouanna, 1999). The present-day town of Cos sits at the eastern end of the island; the classical city Hippocrates would have known was Astypalaea, in the southwest near the modern Kephalos, around an acropolis overlooking the harbor of Kamari (Jouanna, 1999). Excavations at the sanctuary of Asclepius on Cos have revealed nothing earlier than the fourth century BCE, so it is not certain that Hippocrates knew the Asclepieum at all, and there is no evidence that he was ever a priest of Asclepius (Jouanna, 1999).
The Asclepiad designation itself has a more specific sense than later usage suggests. In its original meaning, “Asclepiad” referred not to all physicians but to descendants of Asclepius’s two sons, Podalirius and Machaon, a noble family claiming direct descent from the healing god; only later was the term extended by improper usage to all physicians, a distinction the Byzantine grammarian Johannes Tzetzes preserved and Jouanna restores (Jouanna, 1999). By the genealogical tradition Jouanna reconstructs, Hippocrates’ family belonged to the Asclepiads descended from Podalirius, who after the Trojan War settled at Syrna in Caria; the descendants of Podalirius then split into two great branches, one settling on Cos (Hippocrates’ branch) and the other at Cnidus directly across the strait, a fact attested by the historian Theopompus of Chios, who was born about the time Hippocrates died (Jouanna, 1999) (Jouanna, 1999). Hippocrates was thus, by the same tradition, descended through his mother Phaenerete from Heracles as well as from Asclepius, making him both Asclepiad and Heraclid; the dual descent was not automatic for all members of the wider clan and is asserted on two surviving Roman-period inscriptions from Cos, one of which calls a man “a descendant of Asclepius on one side and of Heracles on the other side” (Jouanna, 1999) (Jouanna, 1999). His ancestor Nebros took part in the First Sacred War and is said to have introduced a drug into the water supply of the besieged city of Crisa to give its inhabitants diarrhea, one of the earliest recorded episodes of biological warfare in Greek tradition; Nebros’ son was buried in the hippodrome at Delphi and given a public cult, marking the beginning of the privileged relations between the Asclepiads and the Delphic sanctuary (Jouanna, 1999) (Jouanna, 1999). Those privileges have a tangible epigraphic confirmation: a decree issued by the koinon of the Asclepiads of Cos and Cnidus, found at Delphi, requires every arriving Asclepiad to swear before consulting the oracle that he is “Asclepiad by male descent” (kat’androgeneian), the same rare expression used in the Speech of the Envoy, which Jouanna treats as strong evidence that the Presbeutikos draws on a good source (Jouanna, 1999) (Jouanna, 1999). A separate dedicatory inscription at Delphi bearing Hippocrates’ own name (incomplete but legible enough to confirm both the name and a reference to diseases) independently corroborates that he came to the sanctuary (Jouanna, 1999).
Hippocrates received his medical education within the family, in keeping with Asclepiad tradition, and that teaching was almost certainly oral and practical rather than textual: Galen, in Anatomical Procedures, records the convention that children of the medical clans practiced dissection from childhood under parental instruction as they did reading and writing (Jouanna, 1999). A later tradition that Hippocrates learned medicine from accounts of healing inscribed on temple steles at the shrine of Asclepius is, on Jouanna’s reading, almost certainly a legend put into circulation by the Asclepiad clergy to appropriate the great physician’s glory; rational Asclepiad medicine did not in fact emerge from the temples (Jouanna, 1999). Hippocrates married into a Coan family of standing (one of his wife’s ancestors, Cadmus of Cos, was the tyrant of the island during the First Persian War), and he and his wife had three children: two sons, Thessalus and Dracon, both trained in medicine in the family tradition, and a daughter who married Polybus, one of Hippocrates’ own students (Jouanna, 1999) (Jouanna, 1999).
Hippocrates left Cos only after the death of his parents (Jouanna, 1999). The biographical tradition records several explanations for the departure, none entirely trustworthy. One, traceable to Andreas (a disciple of Herophilus and physician to Ptolemy IV), claimed Hippocrates left because he had burned down the medical library at Cnidus (Jouanna, 1999); on Jouanna’s reading, this and a parallel arson story share a malevolent purpose, namely to charge Hippocrates with plagiarism by suggesting his knowledge was stolen and the sources destroyed to hide the theft, (Jouanna, 1999) and they testify to an anti-Hippocratic movement among the pupils of Herophilus in Hellenistic Egypt that antedates the better-known Roman mistrust of Greek doctors (Jouanna, 1999). A more reputable account, again traceable to Soranus of Cos, holds that Hippocrates left as a result of a dream commanding him to settle in Thessaly (Jouanna, 1999). The most probable explanation, Jouanna argues, is that Hippocrates wished to enrich his clinical experience by studying the practices of other lands, since the Hippocratic conviction that the natural environment of a place influences health and disease itself supports such a project, a reading Galen had already proposed in his portrait of the ideal physician (Jouanna, 1999). The departure must have taken place during the decade after 430 BCE, since the Speech of the Envoy shows Hippocrates already settled in Thessaly when a plague broke out in 419-416 (Jouanna, 1999).
The textual record of the Hippocratic school’s geographical reach confirms this Thessalian career. The patient names recorded in the Epidemics refer to Larissa and to other Thessalian cities — Meliboea, Crannon, Pharsalus, Pherae — across all three parts of the collection, marking out the territory in which Hippocrates and his disciples practiced over more than half a century (Jouanna, 1999). The non-Thessalian place-names in the Epidemics are mostly northern: Thrace, the Propontis, Macedonia (Jouanna, 1999). Epidemics I and III specifically were composed by an itinerant physician who lived not only in Thessaly but spent at least four years on Thasos, treated patients in Abdera (the city of Democritus), and traveled as far as Cyzicus on the Asiatic side of the Propontis (Jouanna, 1999). The geographical map drawn by these case records gives, in Jouanna’s view, a faithful picture of the sphere of the Hippocratic school’s influence (Thessaly and the north of Greece), and shows that the clinical work of the school as a whole dates from after Hippocrates left Cos, with its height tied to the Thessalian period rather than to his birthplace (Jouanna, 1999) (Jouanna, 1999). Strikingly, Cos itself is barely mentioned in the medical works attributed to Hippocrates: only one writing, Prorrhetic 7, refers to a patient from the island (Jouanna, 1999).
Hippocratic medicine as actually practiced had a characteristic clinical structure. The physician called to a patient examined as many symptoms as possible and then made a prognosis — a forecast of what was likely to happen — rather than a diagnosis in the modern sense. The concept of disease as an entity with a name distinct from the patient who suffers it was largely foreign to Hippocratic practice (Henry E. Sigerist, 1933). Treatment followed a hierarchy: dietary regulation came first, followed by drugs, and surgery only as a last resort. The materia medica was restricted, consisting mainly of vegetable drugs gathered by skilled herbalists (Henry E. Sigerist, 1933). Stapley, reviewing the Corpus from a pharmacological perspective, notes that it contains information on over 350 herbs and preserves the theory that plants draw their tastes — acid, bitter, sweet, and salt — from the nourishment of the earth, equipping each drug to draw a particular element (phlegm, bile, and so forth) in the corresponding patient.(Stapley, 2024) When the Hippocratic physician did intervene surgically, scrupulous cleanliness was expected — a precaution that provided something approximating asepsis (Henry E. Sigerist, 1933).
The Hippocratic tradition’s ethical commitments also shaped its stance toward the acquisition of anatomical knowledge. Followers of Hippocrates objected specifically to the deliberate infliction of wounds for the pursuit of knowledge, holding to the conviction that the physician must do no harm — not only to humans, but significantly to animals as well.(Jackson (ed.), 2011) This ethical stance placed Hippocratic medicine in opposition to the vivisectional practices that Hellenistic anatomists would later develop at Alexandria.
The therapeutic ethic these practices served has its single most famous formulation in Epidemics 1.11, which describes the physician’s task in four short clauses: he should “declare what has happened before, understand what is present, and foretell what will happen in the future. This is what he should practise. As to diseases, he should strive to achieve two things: to help, or to do no harm” (ōphelein ē mē blaptein). The same passage adds that “the (medical) art consists of three components: the disease, the patient, and the doctor. The doctor is servant of the art. The patient should combat the disease in co-operation with the doctor.”(van der Eijk, Philip J., 2005) The “help or do no harm” formula recurs across the Corpus and supplies the moral framework within which the rest of Hippocratic therapeutics has to be read. It does not commit the physician to refusing all intervention in difficult cases. Van der Eijk shows that in nosological texts such as On Diseases 1–3 and On Internal Affections, treatment is recommended even in cases the author knows to be lethal: “When the case is such, the patient wastes away sorrily for a year, and dies; you must treat him very actively and strengthen him.”(van der Eijk, Philip J., 2005) Hippocratic therapeutics is also notably tentative in its language: instructions are routinely qualified with “if you wish,” “if you think it is right,” “if you treat him,” “if you wish to treat him,” “if you do not want to give him the drug,” a non-rigid style that leaves the choice of intervention to the doctor’s judgment about the case in front of him.(van der Eijk, Philip J., 2005)
Care does not stop with recovery. The Corpus warns that “if the patient is not cared for after he has recovered, and does not keep a watch over himself, in many the disease has returned and killed them,” so that the body “needs to be looked after not only when it is healthy or when it is sick, but also when it has turned from sickness to health.”(van der Eijk, Philip J., 2005) This understanding of medicine as continuous bodily care, not merely intervention against acute disease, is one reason van der Eijk argues that dietetics in the Greek tradition is best defined more broadly than as a branch of therapeutics: perhaps “more generally as a care for the body both — and perhaps predominantly — in healthy states as well as (perhaps secondarily) in unhealthy states, or on the interface between the two, as seems to be the position of the author of On Regimen.”(van der Eijk, Philip J., 2005)
The Hippocratic Regimen exemplifies the tradition’s individualized approach. Hippocrates is described by Stapley as prescribing treatment based on the patient’s constitution, age, climate, wind direction, seasonal factors, diet, and exercise, attending to whether the predominant climate is wet and cold or dry and warm, and observing the direction of the prevailing wind.(Stapley, 2024) The same text organized vegetables and culinary herbs by their energetic qualities, distinguishing hot herbs (mustard, rocket, coriander) from cooling ones (lettuce, mint, fresh purslane), drying astringents such as sage, and moistening vegetables such as pumpkin and turnip.(Stapley, 2024) Stapley also summarizes the Corpus’s account of Hippocrates’ place in the tradition, noting that he was born on the island of Cos about 460 BC, and that the Corpus consists of around seventy manuscripts varying in length and quality, with the Aphorisms considered by some scholars as most likely to reflect his actual views.(Stapley, 2024)
The Construction of a Legend
Graeco-Roman medicine has always occupied a privileged position in general accounts of the history of medicine, typically placed at the beginning as the rational foundation or “cradle” of the Western medical tradition, with Hippocrates cast as its great hero — the “Father of Medicine” — and Galen as “the Prince of Physicians” who secured its legacy.(Jackson (ed.), 2011) The cultural content attributed to Hippocrates’ name was equally foundational: the Hippocratic Oath was believed to have laid the ethical basis for the profession; the Epidemics provided the model for the clinical case-history based on meticulous empirical observation; and On the Sacred Disease advanced rational, natural explanation of phenomena (epilepsy above all) that had previously been ascribed to the divine and supernatural.(Jackson (ed.), 2011)
The legendary Hippocrates was built over centuries through three converging tendencies: the Greek cultural habit of seeking out the lives of great men, the accretion of anonymous medical texts around a famous name, and the growth of an interpretive tradition that elevated certain texts above others (Nutton, 2023).
By the Hellenistic period, the legend was flourishing. Spurious letters and speeches appeared, emphasizing Hippocrates’s wisdom, patriotism, and shrewdness — a body of biographical invention that scholars have only recently recognized as fabrication (Nutton, 2023). Late additions to the Corpus, including Decorum, Precepts, and The Physician, reflect Hellenistic institutional concerns and constructed an idealized physician: a man of virtue, wisdom, and philanthropic conduct who was “the equal of a god” (Nutton, 2023). Pormann, surveying the full sweep of this reception, notes that Hippocrates’ appeal crossed every boundary of country and creed: Christians, Jews, and Muslims appropriated him in various ways, and his influence in Arabic is arguably greater than in Latin, with his fame reaching as far as India and China (Pormann (ed.), 2018).
The accumulation of sayings attributed to Hippocrates illustrates the same dynamic. Beyond the Aphorisms, other pithy sayings circulated widely: “conflux one, conspiration one, all things in sympathy”; “moisture is the vehicle of nutriment”; and “to refuse to treat those overmastered by their diseases” (Pormann (ed.), 2018). Still other phrases attributed to him do not appear anywhere in the surviving Corpus — among them “coitus is a slight epileptic attack” and “the cure for the foot is rest” (Pormann (ed.), 2018). His prestige commanded such authority that his name alone increased in symbolic value as less and less was actually known about his life, and as it became increasingly difficult to determine which works attributed to him were genuine (Pormann (ed.), 2018).
Sigerist captured the logic of this process precisely: what we certainly know of Hippocrates is that he lived, yet no doctor ever exerted a more far-reaching influence than he. Each successive epoch formed a new picture of Hippocrates and incorporated its own yearnings in his ideal figure. What people found wanting in the doctors of their own day, they thought of as having existed in Hippocrates, who thus became a perpetual exhortation (Henry E. Sigerist, 1933). In early Alexandria, he was ranked alongside Praxagoras and Chrysippus as one of three leading authorities on dietetics; from century to century, his fame grew until Galen elevated him to the status of the ideal physician (Henry E. Sigerist, 1933).
The most consequential stage of legend-building came with Galen, who identified with Hippocrates so completely that he projected onto his hero theories and practices that Hippocrates was unlikely to have held. Much of what Galen presented as uniquely Hippocratic — the primacy of anatomy, the tripartite division of the body’s systems — has little basis in the Hippocratic Corpus itself (Nutton, 2023). Galen created an unerring Hippocrates in his own image (Nutton, 2023), and because Galen dominated Western medicine for the next fifteen centuries, his Hippocrates became everyone’s Hippocrates.
Smith’s analysis of Galen’s rhetorical posture reveals the mechanism in detail. Galen constructed an ideal physician who could not care for both science and money; if he followed Hippocrates, he would limit his concern for wealth (Wesley D. Smith, 1979). Galen extended this into philosophical territory, arguing that Plato was not only largely correct in his physiological and psychological doctrines but was furthermore the follower of Hippocrates (Wesley D. Smith, 1979). His treatise Elements according to Hippocrates asserts that Hippocrates is the archegete (first founder) in elemental philosophy as well as in medicine (Wesley D. Smith, 1979). The fact that Hippocrates used the word gnome in The Surgery became, for Galen, proof that Hippocrates gave reason equal status with sense perception (Wesley D. Smith, 1979).
Galen did not claim that one could learn sphygmology directly from the Hippocratic Corpus, but presented Hippocrates as not ignorant of the science of the pulse (Wesley D. Smith, 1979). His Therapeutic Method makes the most reasoned claims to follow the science of Hippocrates, arguing that Hippocrates showed the way and that his system was the only proper basis for a method of healing (Wesley D. Smith, 1979). Yet Galen’s rhetorical posture in relation to Hippocrates was partly a superficial denial of what he was obviously doing: innovating while claiming merely to recover ancient wisdom (Wesley D. Smith, 1979). Against what he called barbarism of all kinds, Galen allied himself with the classical age of Hippocrates and Plato (Wesley D. Smith, 1979).
A late Galenic reception is also documented in the case of Athenaeus of Attaleia, founder of the Pneumatist school, who held that the proper balance of hot and cold in pneuma constituted almost a fifth element and equated this with the Hippocratic concept of innate heat, exploring parallels between the microcosm of the body and the macrocosm of the universe (Nutton, 2023). The Pneumatists are one illustration of how Hippocrates’ name was attached to doctrines that developed long after his death.
Temkin’s study of Hippocrates’ reception traces the full arc of this process through paganism and into Christianity. As a classical author, Hippocrates stood alongside Homer and Thucydides as one of the pillars of ancient culture; his writings proved him a model of honesty and courage, an educator who led physicians toward humane behavior, and a person of exceptional wisdom.(Temkin, 1991) A single episode in the Epidemics — his frank confession of a fatal diagnostic mistake, having mistaken injury fissures for skull sutures so that trephination was not performed in time — was read by Celsus as an example of “a great man’s love of truth in great matters,” and became a touchstone of intellectual honesty for Quintilian, Plutarch, and the Emperor Julian.(Temkin, 1991) The first aphorism, “Life is short, but the art is long,” placed him in the company of outstanding philosophers; Seneca read it as a complaint about the brevity of human life, while Stoics like Zeno extended it far beyond medicine to cover all the arts.(Temkin, 1991) An anonymous preface to a collection of Problems gave the aphorisms three levels of meaning: a precise individual significance, a systemic medical meaning where each aphorism supports the others, and a universal applicability to all life — making Hippocrates comparable to Plato as a writer of universally valid law.(Temkin, 1991) The jurist Paul (c. 200 CE) cited Hippocratic authority on the viability of seven-month births to settle questions of legal legitimacy — “a fetus born in the seventh month is perfect has now been accepted owing to the authority of that very learned man, Hippocrates” — demonstrating that Hippocratic expertise extended beyond the consultation room into civil law.(Temkin, 1991)
Unlike Asclepius (whose healing miracles were part of an official cult) and Apollonius of Tyana (deployed as a pagan rival to Christ), Hippocrates never became a competitor of Jesus. He remained, in Temkin’s formulation, a hero and sage but the human head of a secular art — and this precisely is what allowed the Hippocratic tradition to survive the transition from pagan to Christian culture intact.(Temkin, 1991)
The Hippocratic Corpus
The Corpus is a collection of approximately sixty texts composed by different authors between roughly 430 and 330 BCE. It is not a coherent body of doctrine. Sigerist puts the problem plainly: close study shows the texts lack uniformity and expound the most contradictory views, with some utterances expressly directed against others (Henry E. Sigerist, 1933). King notes that the corpus was assembled probably in the third or second century BCE and was never the work of a single author, despite the singular name attached to it (King, 1998). The traditional division of Hippocratic texts into a rational “Coan” school and a more primitive “Cnidian” rival has been shown by Ian Lonie to be an entirely historiographical construct, invented to fill a gap in the developmental narrative rather than reflecting any historical reality (King, 1998). The texts disagree with one another on fundamental questions: whether disease has natural or divine causes, whether the physician should treat aggressively or conservatively, whether theory should guide practice or practice generate theory.
The intellectual soil from which Hippocrates emerged included a network of regional medical schools. By the sixth century BCE, schools had arisen at Croton (where Pythagoras dwelt), in Sicily, in Cyrene, at Rhodes, and especially at Cnidus and Cos (Henry E. Sigerist, 1933). The Pythagoreans, above all, were greatly interested in medical problems and sought a dietetics of both mind and body (Henry E. Sigerist, 1933).
By the mid-fourth century BCE, medicine was no longer the preserve of a group of clans but a subject publicly debated and capable of being taught to anyone who could afford a master’s fee (Nutton, 2023).
Far more papyri of Hippocratic texts survive from Graeco-Roman Egypt than of any other medical author, and references to Hippocrates appear across writers of all kinds, from philosophers to theologians (Nutton, 2023). A revealing instance of the Corpus’s later authority: a first- or early second-century CE text known as the Anonymus Parisinus compiled in doxographical format the views of Hippocrates, Diocles, Praxagoras, and Erasistratus on the causes of specific diseases including epilepsy, ileus, and tetanus (Nutton, 2023).
The Four-Humour Question
The doctrine most firmly associated with Hippocrates — that health depends on the balance of four bodily humours (blood, phlegm, yellow bile, black bile) — was almost certainly a minority position within the Corpus, developed by Polybus rather than by Hippocrates himself (Nutton, 2023). The Anonymus Londinensis evidence suggests Hippocrates held a different physiological theory entirely (Nutton, 2023). Stapley records that the Nature of Man text names blood, phlegm, yellow bile, and black bile as constituting the body, and frames this as a pattern of belief that held sway for over a thousand years.(Stapley, 2024) Within the same tradition, the Regimen text describes the body as composed of fire and water, with fire carrying hot and dry qualities and water carrying cold and moist ones, and uses this framework to distinguish male from female constitutions: females incline to water and are nourished by cold, moist, and gentle foods; males incline to fire and are nourished by dry and warm regimen.(Stapley, 2024) Galen later elaborated these elemental correspondences into a full systematic table: blood corresponds to air (hot and moist), flourishing in infancy and spring; yellow bile to fire (hot and dry), dominant in youth and summer; black bile to earth (cold and dry), increasing in middle age and autumn; phlegm to water (cold and moist), characteristic of old age and winter.(Stapley, 2024)
Sigerist’s survey of the humoral debate within the Corpus captures its internal plurality: some authors declare there are many humours, others insist on two cardinal humours (bile and mucus), and still others articulate the four-humour scheme of two pairs with opposed qualities (blood and black bile, yellow bile and mucus). What all versions share is a premise: health depends on equilibrium, and illness results when one humour is present in excess or is corrupted, at which point the organism endeavours through its natural healing forces to restore balance (Henry E. Sigerist, 1933).
Jouanna’s philological analysis traces the formation of the Corpus through three stages: an original Coan core known to Bacchius in the third century BCE, Cnidian treatises added by Erotian’s time in the first century CE, and medieval additions of unknown provenance (Jouanna, 1999). The quantitative growth of the attributed corpus tracks this expansion: Bacchius of Tanagra, a disciple of Herophilus and one of the first Hippocratic commentators, attested about twenty texts attributed to Hippocrates; three centuries later Erotian mentioned about forty; and the 1526 Aldine edition contained sixty or so treatises. (Hynek Bartoš and Vojtěch Linka, 2024) Littre in the nineteenth century attributed only eleven of the sixty-odd treatises to Hippocrates himself, and modern scholarship is even more skeptical (Jouanna, 1999).
The Hippocratic Question and Textual History
The question of which texts, if any, the historical Hippocrates actually wrote has occupied scholars since antiquity and remains unresolved. Pormann, in his introduction to the Cambridge Companion to Hippocrates, states the problem simply: the Corpus spans texts composed from the fifth century BCE to the first or second century CE, making it not the work of a single author but a heterogeneous collection accumulated over several centuries (Pormann (ed.), 2018). No text in the sixty or so collected under Hippocrates’ name can be unequivocally proclaimed as his work (Pormann (ed.), 2018). Philip van der Eijk has proposed abandoning the designation “Hippocratic” for texts in the Corpus altogether, on the grounds that it implies a false unity and a connection to the historical Hippocrates that cannot be sustained (Pormann (ed.), 2018).
Craik’s contribution to the same volume surveys the historical problem most directly. She confirms that the classical attestations (Plato and Aristotle) provide minimal biographical data and nothing that allows attribution of specific treatises (Pormann (ed.), 2018). She also argues that the traditional Coan/Cnidian division — long used as an organizing framework for Hippocratic scholarship — has been largely abandoned by modern scholars, who regard it as an oversimplification that does not reflect the actual diversity within the texts (Pormann (ed.), 2018). The four-humour theory, often treated as the core Hippocratic doctrine, in fact makes only a sporadic appearance in the Corpus and is systematically presented chiefly in Nature of Man; most texts use different frameworks (Pormann (ed.), 2018). Against this skepticism, Craik herself argues there is a reasonable case for identifying Hippocrates of Cos as the author of Fractures and Joints (which originally formed one work), on the grounds of their shared style, method, and surgical expertise (Pormann (ed.), 2018). Craik extends this case somewhat further in the Cambridge Companion’s biographical chapter: the strongest candidates for genuine Hippocratic authorship are Fractures and Joints and possibly Prognostic, Prorrhetic 2, and Epidemics 1 and 3, though “possibly” carries significant weight in each case.(Pormann (ed.), 2018) Some documents in the Corpus were, she notes, invented specifically to furnish evidence for Hippocrates’ loyalties and associations rather than to record clinical or theoretical content.(Pormann (ed.), 2018) The Hippocrates-Democritus correspondence is an example at the more complex end of this spectrum: a demonstrable pastiche in its current form, yet one that may reflect genuine patterns of intellectual interaction in fifth-century Thrace rather than pure invention.(Pormann (ed.), 2018)
Galen’s classification of Hippocratic texts into three categories — genuine, authentic, and spurious — dominated the scholarship until the twentieth century (Pormann (ed.), 2018). Galen distinguished authentic from inauthentic texts according to what Bartoš and Linka’s 2024 volume describes as his “thoroughly subjective notion of what was worthy or unworthy of Hippocrates,” and he devoted an entire (now lost) treatise to the topic: On the Authentic and Illegitimate Writings of Hippocrates. (Hynek Bartoš and Vojtěch Linka, 2024) This lost work is itself a testament to how consequential the authenticity question had become by the second century CE. Littré, producing his eleven-volume edition between 1839 and 1861, expanded this to eleven categories based on content, style, and presumed authorship (Pormann (ed.), 2018). Littré’s edition long served as the standard reference work and established the convention of citing Hippocratic texts by his volume and page numbers (abbreviated “L.”) (Pormann (ed.), 2018). The Corpus Medicorum Graecorum project, begun in 1904, undertook critical editions of ancient medical texts and has provided modern scholarly editions for much of the Hippocratic and Galenic literature (Pormann (ed.), 2018). The international Colloque Hippocratique, a scholarly conference series held regularly since 1972, remains the main forum for advances in Hippocratic scholarship (Pormann (ed.), 2018).
Jouanna, the leading authority on the textual history of the Corpus, has identified approximately seventy-two treatises in the current collection, though the exact number varies depending on whether certain texts count as separate works or parts of the same work (Pormann (ed.), 2018). The two oldest surviving manuscript witnesses are Marcianus gr. 269 (tenth century, sigla “M”) and Vaticanus gr. 276 (eleventh to twelfth century, sigla “V”), which form the foundation of modern textual criticism (Pormann (ed.), 2018). The Aldine editio princeps of the Hippocratic Corpus in Greek was published in Venice in 1526, making the texts widely available in print for the first time and stimulating Renaissance engagement (Pormann (ed.), 2018). The transition from papyrus scroll to codex in Late Antiquity introduced textual errors, as copyists unfamiliar with the technical vocabulary made mistakes or incorporated marginal glosses into the main text (Pormann (ed.), 2018). In the Latin medieval West, the Corpus circulated primarily through the Articella, a collection of medical school texts that included the Aphorisms and Prognostic in Latin translation, serving as the basis for university medical education from the twelfth century onward (Pormann (ed.), 2018). The Aphorisms is attested by ten surviving papyri, more than any other Hippocratic work — a measure of its popularity across the ancient world (Pormann (ed.), 2018).
A critical feature of the indirect tradition: Galen’s commentaries on Hippocratic texts sometimes preserve lemmas (quoted passages) that represent older and better readings than those found in medieval manuscripts copied from the Corpus itself, making Galen’s quotations an irreplaceable witness to the pre-medieval state of the text (Pormann (ed.), 2018). Galen refers to Hippocrates more than 2,500 times in his extant works, and his commentaries shaped how the Corpus was read for over a thousand years (Pormann (ed.), 2018). The Arabic reception both transmitted and complicated this influence: Arabic translators and commentators worked largely through Galen’s lemmas, so that the Hippocratic text embedded in Arabic commentaries was itself filtered through Galen’s understanding (Pormann (ed.), 2018).
Some treatises in the Corpus enjoy an influence disproportionate to their scholarly merit. Craik notes that Ancient Medicine owes its prominent position in modern discussion primarily to Littré’s decision to place it first in his edition; it is important but not uniquely so (Pormann (ed.), 2018). The alleged “rational” character of On the Sacred Disease has been exaggerated: scholars cite a few sentences from that text as proof of Greek medicine’s rationalism, but the author’s stance is arguably traditional, and irrational attitudes persisted throughout Greek medicine even in Galen’s time (Pormann (ed.), 2018). Theories of flux and fixation of peccant matter, though ubiquitous in Hippocratic physiology and pathology, have received relatively little attention in the scholarly literature (Pormann (ed.), 2018).
Hippocrates and the Gynecological Corpus
The Corpus is written in the Ionian dialect, but scholars have traced Doric tendencies in the text, explained by Hippocrates’ origin on Cos. Later manuscript scribes sometimes imposed hypercorrect Ionian forms — what editors call “hyperionisms” — in an attempt to produce a consistent Ionic text, with the result that modern editors must present the state of the text with its dialect variants rather than silently imposing a uniform dialect (Pormann (ed.), 2018).
Approximately one quarter of the Hippocratic corpus concerns the diseases of women (King, 1998). Helen King’s Hippocrates’ Woman (1998) argues that the gynecological texts must be understood as historical constructs shaped by social and cultural context rather than as objective medical truth (King, 1998).
The gynecological treatises — particularly the three-volume Diseases of Women — rest on a model of sexual difference that goes beyond the Galenic “one-sex body” in which women are simply colder men. In the Diseases of Women texts, women are assumed to be creatures entirely different from men in the texture of their flesh and in the associated physiological functions (King, 1998). Women’s flesh is described as looser, wetter, and spongier than men’s — like wool compared to woven cloth — making women absorb more fluid and necessitating regular menstruation to purge the excess (King, 1998). If the menses do not flow, the surplus blood builds up until disease or even death results: “if the menses do not flow, the bodies of women become sick” (On Generation 4) (King, 1998).
The central anatomical concept distinguishing women from men in these texts is the hodos, a route extending from the orifices of the head to the vagina: woman has an uninterrupted internal tube from nostrils to womb, with a mouth (stoma) at each end that can be read diagnostically and used therapeutically (King, 1998). The womb was understood not as the primary organ but as a secondary vessel made necessary by the fluid-absorbing nature of female flesh, needing somewhere to store blood the flesh could not use (King, 1998). Crucially, Hippocratic anatomical knowledge of the female body derived not from dissection but from deducing interior structure from external signs and analogy with animal anatomy observed through sacrifice and butchery (King, 1998). It was not until third-century BCE Alexandria and the work of Herophilos that systematic anatomy on human bodies was carried out, revealing ovaries and Fallopian tubes — though not yet falsifying the wandering womb theory (King, 1998).
The statement in Diseases of Women 1.62 — that the treatment of women’s diseases “differs greatly from that of men” — was later called “the founding act of ancient Greek gynaecology” by Paola Manuli, and appeared on the title page of Maurice de la Corde’s 1574 commentary, demonstrating the text’s long reach into early modern medicine (King, 1998).
Therapy for Women’s Diseases
Hippocratic therapy for women’s diseases was extensive and technically sophisticated. Interventions included dietary modification, fumigation (a complex multi-day procedure using earthenware apparatus), pessaries, bandaging, vapour baths, and scent therapy (King, 1998). The Hippocratic concept of healthy menstrual blood described it as flowing “like that of a sacrificed victim” — hot, red, and quickly coagulating — a comparison King identifies as gender-specific and restricted to the gynecological texts, linking women’s physiology to the civic institution of animal sacrifice (King, 1998) (King, 1998). The corpus understood breast milk as menstrual blood diverted and refined, linking breasts and womb as organs in a shared female physiological economy, so that heavy menstruation could be treated by applying cupping-glasses to the breasts (King, 1998). Hippocratic texts specified that a healthy woman should lose two Attic cotyls (approximately a pint) over two to three days each month, a quantity that would indicate pathological haemorrhage by modern standards (King, 1998).
The gynecological pharmacopoeia included agnos castus (Vitex agnus-castus), used both as an astringent to check excessive flux and as an expulsive agent to bring on menstruation, induce labour, and expel the afterbirth (King, 1998). The Greek word for drugs, pharmakon, carried the double sense of healing remedy and poison, and the great poisoners of antiquity were predominantly women; this linguistic fact framed female pharmaceutical knowledge as inherently double-edged and potentially threatening to male social order (King, 1998).
On the Diseases of Virgins presents a striking Hippocratic application of menstrual physiology to menarche (King, 1998). At menarche, blood unable to exit presses on the heart and diaphragm (King, 1998), producing delirium, visions that compel the girl to seek death by hanging or drowning, and an erotic fascination with death (King, 1998). The prescribed remedy is marriage and pregnancy; diviners who recommend dedications to Artemis instead are condemned as “thoroughly deceitful” (King, 1998). The text survived only in the Arabic tradition from the eighth or ninth century until Marco Fabio Calvi’s 1525 Latin translation made it available to Western readers (King, 1998).
Twenty-one out of twenty-five Hippocratic uses of the opium poppy occur in the gynecological texts, but the most common purpose of its administration is to recall a wandering womb — illustrating how narcotic plants were deployed within an explanatory framework entirely different from pain relief (King, 1998). The Greek word for menstrual suppression is revealing: there is no Greek term for a “missed” period; instead the Greeks said the blood was “hidden” within the body, making menstrual suppression always pathological rather than a neutral physiological event (King, 1998).
The “Wandering Womb” and Hysteria
Among the Hippocratic corpus’s most influential doctrines is the concept of the womb as capable of movement through the body, drawn toward moist organs like the liver and producing dramatic symptom clusters — seizure-like states, suffocation, lividity — depending on its destination (King, 1998). Diseases of Women 1.7 describes the womb “throwing itself” onto the liver when dried out by fatigue, and this passage became the primary Hippocratic anchor for all subsequent hysteria theories (King, 1998). Despite later association with Hippocratic authority, the word “hysteria” does not appear in the Hippocratic corpus; the term hysterika in Aphorisms 5.35 is an adjective meaning “things to do with the womb,” not a disease name — a confusion introduced by Littré’s nineteenth-century translation headings (King, 1998).
The womb-as-animal idea — so central to later hysteria theories — derives not from the Hippocratic corpus but from Plato’s Timaeus; Galen attributed this theory to Plato and explicitly denied it was Hippocratic (King, 1998). King argues that the Hippocratic corpus emphasises symptom description and cause-based classification rather than unified disease labels, making retrospective diagnosis of “Hippocratic hysteria” methodologically inappropriate and historically misleading (King, 1998).
Soranus of Ephesus argued that menstruation is harmful to women’s health and that perpetual virginity represents the best option for both sexes, contradicting the Hippocratic framework (King, 1998).
Female Healers and Midwifery
The gynecological texts bear indirectly on the question of who actually treated women in the ancient world: one passage in Diseases of Women 1.68 describes a woman designated as an iatros (a healer) assisting in a difficult birth alongside a male colleague, evidence that female practitioners existed but operated within ideological constraints that limited their scope (King, 1998). The Hippocratic corpus contains no treatise on obstetrics, which is commonly taken to indicate that ordinary midwifery was a taken-for-granted female activity while Hippocratic practitioners were summoned only for difficult or dangerous cases (King, 1998). Soranus, writing in the second century CE, recorded that “the public is wont to call in midwives in cases of sickness when the women suffer something peculiar which they do not have in common with men,” which suggests midwives were consulted as general women’s healers, not merely birth attendants (King, 1998).
The Corpus as Ideological Instrument
The gynecological corpus mapped female physiology onto a single correct life-path: all women must pass through the category of virgin (parthenos) before becoming wives (gynaikes), and only pregnancy could stabilise the inherently unstable female constitution (King, 1998). The Pandora myth supplied the ancient cultural warrant for treating women’s bodies as requiring separate, specialist medicine; King argues that women as a “separate creation” requiring a different kind of medical attention is the mythological basis for the gynecological corpus as a whole (King, 1998). In the Pandora myth, woman contains a womb-jar (gastêr) and a bitch-mind; she is a late construction, an artifice, and it is this image of woman as a separate race, biologically distinct and requiring specialist management, that makes Hippocratic gynaecology both possible and necessary as a distinct body of medical knowledge (King, 1998).
The Hippocratic Aphorisms was one of the most widely copied texts in the corpus, circulated in both the West and Arab world, translated from Arabic into Latin by Constantine the African, and the first to be printed (King, 1998). Two diseases constructed entirely from classical texts and given deliberately classicising names then applied to real women were chlorosis and hysteria; the common ideological conclusion of both was that marriage was woman’s proper destination (King, 1998). The term “chlorosis” was not coined until 1619 by Varandal of Montpellier, who wrongly claimed it was a Hippocratic word that does not in fact appear anywhere in the corpus (King, 1998).
The Hippocratic Diseases of Women treatises were historically marginalised by traditional Hippocratic scholarship as “Cnidian” and irrational, yet they were regarded as genuinely Hippocratic in antiquity by Galen (King, 1998). The erasure of these texts from the “core” Hippocratic canon reflects the same mechanism by which the corpus’s enormous diversity enables each tradition to find within it texts supporting its own preferred identity (King, 1998).
The Modern Hippocratic Tradition
Smith argues that the standard medical-historical narrative about Hippocrates is an ‘etiological myth’ dressed as history, derived from Enlightenment assumptions where priests, tyrants, and speculation are enemies of progress, while the unique genius who observes Nature is its hero (Wesley D. Smith, 1979).
The process of remaking Hippocrates began with Paracelsus (1493-1541), who took the crucial first step of dissociating Hippocrates from Galen in spirit and doctrine (Wesley D. Smith, 1979). Paracelsus claimed Hippocrates had possessed the true medical insight but that Galen and other “sophists” had perverted it (Wesley D. Smith, 1979). Thomas Sydenham built on Francis Bacon’s interpretation and emulated Hippocrates as the careful observer; for this new Hippocratism, “Hippocrates” was a spirit and a method rather than a body of doctrine (Wesley D. Smith, 1979). Boerhaave’s influential Institutiones Medicinae then created the template for all subsequent medical historiography, establishing a narrative in which medicine progresses naturally from observation through experience to science, Hippocrates unified Greek medicine, and Galen introduced excessive theorizing (Wesley D. Smith, 1979).
Daniel Le Clerc’s Histoire de la Médecine (1696) offered the evaluative generalization that would determine the subsequent course of Hippocratic scholarship, but his evaluations remained superficial (Wesley D. Smith, 1979). Le Clerc outlined Hippocrates’ view of the sources of health and disease according to the four-humour, four-quality theory (Wesley D. Smith, 1979), and in comparing Galen’s medicine with that of Hippocrates, agreed with Galen’s own claims to have followed Hippocratic principles (Wesley D. Smith, 1979).
Kurt Sprengel, writing in the early nineteenth century, compared the problem of the Hippocratic writings to that of the Homeric poems, and argued that Hippocrates’ doctrine could only be recovered by subtracting from the Corpus all Platonism, Aristotelianism, and other later intrusions (Wesley D. Smith, 1979). Sprengel concluded that Hippocrates showed physicians that observation alone was the basis of medicine, proving the uselessness of theories (Wesley D. Smith, 1979). He accepted that the humoral and elemental theory of the first part of Nature of Man must express genuinely Hippocratic views (Wesley D. Smith, 1979).
The Romantic interpretation pushed further. One account presented Hippocrates as unique and heroic, a figure who freed himself from oriental dogmatism and priestly caste and ascended alone the steps of rational science and moral dignity (Wesley D. Smith, 1979). Max Neuburger’s twentieth-century work exemplified the result: once he had established his interpretive principles, the Corpus became a selection table from which he could choose the elements that appealed to him in each treatise (Wesley D. Smith, 1979). Neuburger’s historical scheme organized early Greek medicine into three geographical streams — the Cnidians working on disease description, the Coans seeking conceptual unity subject to prognosis, and the Sicilians attempting to arrive at first principles through natural philosophy, from which to derive theories of disease and treatment. (Wesley D. Smith, 1979) Smith characterizes this entire tradition of Hippocratic historiography as shaped by the “fount of false as well as true medical history” — Galen — whose interpretive choices echo across every subsequent attempt to reconstruct the ancient tradition. (Wesley D. Smith, 1979)
Littre, editing the Corpus between 1839 and 1861, was the last complete interpreter for whom Hippocratism was alive in day-to-day practice. He promoted Auguste Comte’s positivism and read Hippocrates through the lens of the Paris school’s emphasis on observation and expectative therapy (Wesley D. Smith, 1979). His decisive move was assigning Ancient Medicine rather than Nature of Man as the key to Hippocratic doctrine, reversing Galen’s judgment (Wesley D. Smith, 1979).
The discovery of the Anonymus Londinensis papyrus shocked scholars: Aristotle’s pupil Meno had attributed to Hippocrates the doctrines of Breaths, a treatise the scholarly world considered intellectually unworthy of the master (Wesley D. Smith, 1979). Fragments of Menon’s lost history of medicine came to light in a papyrus roll from Egypt, and Menon’s report of Hippocrates’ doctrines was readily recognized by Diels to be a digest of the doctrines of one of the works of the Corpus, Breaths (Wesley D. Smith, 1979).
Karl Deichgraber’s influential 1933 monograph renounced skepticism about Hippocrates’ relation to the Corpus Hippocraticum and argued that three generations of the Coan school were represented in the three groups of books in the Epidemics (Wesley D. Smith, 1979) (Wesley D. Smith, 1979). W.H.S. Jones, who worked on the relationship between philosophy and medicine, conceded that the question of authorship was not likely ever to be settled (Wesley D. Smith, 1979). Ludwig Edelstein came closest to a radical critique, arguing that Hippocratic prognosis was a social tool (establishing reputation without credentials) rather than incipient science (Wesley D. Smith, 1979).
Smith’s Regimen Thesis
Smith’s most controversial thesis is that the historical Hippocrates probably authored the treatise Regimen — a conclusion he calls “hitherto unheard-of” but which follows from reading the pre-Alexandrian evidence without the assumptions inherited from Galen and the Enlightenment (Wesley D. Smith, 1979).
The argument begins with the Platonic evidence. Plato’s Phaedrus sees a parallel between Hippocrates’ method and the process of knowing together and knowing separately (gnosis and diagnosis) (Wesley D. Smith, 1979). Regimen addresses itself to heat and cold as operative principles in diet, drugs, and environment, arguing that all must be balanced (Wesley D. Smith, 1979). Its fourth chapter states that whenever it speaks of becoming or perishing it is merely using popular expressions, meaning in reality mingling and separating (Wesley D. Smith, 1979). Smith further claims that Hippocrates discovered, in addition to all the foregoing factors of diet and exercise, prodiagnosis — the ability to anticipate a patient’s condition before symptoms fully manifest (Wesley D. Smith, 1979).
The Menon evidence is central to Smith’s case. He suggests that Menon, the first known historian of medicine, read Regimen and based his report of Hippocrates’ doctrine on it (Wesley D. Smith, 1979). Menon organized his survey of earlier medicine according to two essential categories of disease cause: perissomata (residues left over from digestion) and stoicheia (the elemental components of the body), placing each physician in a sequence in which each disagrees in some particular with those before him. (Wesley D. Smith, 1979) Hippocrates’ peculiarity, according to Menon, was to say that physai (gas, winds) cause disease (Wesley D. Smith, 1979). Regimen has precisely this theory: altered food that remains in the intestines creates gas, which in turn causes illness (Wesley D. Smith, 1979). Smith argues, however, that Menon imported the common Aristotelian term perissomata (residues) into the text of the writers he reported, distorting the original (Wesley D. Smith, 1979), and that Menon probably fabricated a line of reasoning for Hippocrates in a manner similar to that of Aristotle himself (Wesley D. Smith, 1979). No one in antiquity adduced Menon as a witness for the authenticity or lack of it of any work in the Hippocratic Corpus (Wesley D. Smith, 1979). Despite these qualifications about Menon’s reliability, Smith concludes that it is very likely that Hippocrates wrote the work Regimen that has come down in the Corpus (Wesley D. Smith, 1979).
Sigerist drew a sharp distinction between Hippocrates and Sydenham (Henry E. Sigerist, 1933). Hippocrates, Sigerist argued, recognised only sick individuals (never disease as a generalisable entity) and treated each case as a unique, unrepeatable event (Henry E. Sigerist, 1933). Sydenham’s contribution was precisely the opposite: where Hippocrates saw only cases, Sydenham saw types (Henry E. Sigerist, 1933). Sydenham’s method was ontological, directed toward disease entities that could be classified like botanical species; the Hippocratic method was, by contrast, purely individual (Henry E. Sigerist, 1933). [GAP: The paragraph’s final claim that this contrast complicates the standard narrative about Sydenham as “the English Hippocrates” is not supported by the cited card.]
Smith synthesised Edelstein’s radical critique more fully than most commentators acknowledged. Edelstein had argued that the entire myth of Hippocrates as father of medicine arose after the Alexandrian period, grounded in the Corpus rather than in anything verifiable about the historical man; since the pre-Alexandrian evidence (Plato and Aristotle) says nothing that requires attributing the Corpus to Hippocrates, the elements of the Hippocratic legend (his rational method, his opposition to superstition, his clinical acuity) are post hoc constructions (Wesley D. Smith, 1979). Smith found Edelstein’s negative conclusions more convincing than his positive proposals but saw that Edelstein had cleared the ground for a genuinely non-Galenic reading of the pre-Alexandrian evidence.
The Early Dogmatics and the Non-Hippocratic Tradition
The most important revisionary finding in Smith’s The Hippocratic Tradition concerns not the modern reception but the ancient one. The physicians conventionally listed as Hippocrates’ intellectual heirs or rivals — Diocles of Carystus, Praxagoras of Cos, Herophilus of Chalcedon, and Erasistratus — turn out, on Smith’s careful source criticism, to have had no meaningful relationship with Hippocrates at all.
Diocles of Carystus is conventionally described as “second in time and fame to Hippocrates,” but Smith argues that this designation is a fabrication of later doxographic lists rather than a historical fact.(Wesley D. Smith, 1979) The argumentum ex silentio is, in this case, unusually strong: Diocles was silent about Hippocrates, and if Diocles had discussed him, Galen would not have let it pass.(Wesley D. Smith, 1979) The same evidentiary problem affects Praxagoras: all available information about Praxagoras’s relation to Hippocrates comes from Galen’s rhetorical formulations and is therefore worthless as independent historical evidence.(Wesley D. Smith, 1979) Herophilus represents a slightly different case. His only recorded criticism of Hippocrates concerned the distinction between prognosis and prorrhesis, a narrow technical disagreement that Galen inflated into an imaginary intellectual quarrel.(Wesley D. Smith, 1979) Any notion of Herophilus as a proponent of Hippocratism is, Smith concludes, groundless.(Wesley D. Smith, 1979) Erasistratus apparently never discussed Hippocrates at all, and Galen’s silence on any such discussion is positive evidence of that absence.(Wesley D. Smith, 1979)
The general conclusion is stark. All the early dogmatics (Diocles, Praxagoras, Herophilus, Erasistratus) were neither followers nor opponents of Hippocrates.(Wesley D. Smith, 1979) The list of Dogmatics with Hippocrates at its head, which forms the backbone of later medical historiography, evolved not from any genuine intellectual lineage but from later attempts to write medical history using Empiric categories.(Wesley D. Smith, 1979)
The Alexandrian Library then played its own role in consolidating the legend. Smith documents that the Library sorted old medical works and styled them all Hippocratic, a curatorial decision that retrospectively unified a heterogeneous collection under a single authoritative name.(Wesley D. Smith, 1979)
The Empirics and “Hippocratic Medicine”
Smith argues that the concept of Hippocratic medicine itself is a later construction. In the period of creative fourth- and third-century dogmatic medicine, there is no evidence that any physician acknowledged Hippocrates as an authority to be followed or dethroned (Wesley D. Smith, 1979). It was the Empirics, roughly 225-50 BCE, who first revived the archaic medical works collected by the Alexandrian library and attributed them en bloc to Hippocrates, admiring them as records of useful medical experience unaffected by dogmatic theorizing (Wesley D. Smith, 1979). The Empirics wrote the first commentaries on the Corpus, and “Hippocratism” as a medical identity began with their claim that Hippocrates was empiric (Wesley D. Smith, 1979). Their interpretation was programmatic: the Empirics considered Hippocratic prognosis derivable only from experience, making the Corpus useful evidence for their own methodological commitments.(Wesley D. Smith, 1979)
Greek Medicine in Rome
The Roman reception of Hippocrates was more varied, and more contentious, than the standard narrative of unbroken reverence suggests. Smith’s analysis of the first century BCE through the second century CE reveals a spectrum of positions that ranged from qualified admiration to outright rejection.
Asclepiades of Bithynia, practicing in Rome in the late Republic, represents the sharpest break. He rejected Hippocratic critical days (the theory that crises in fever occurred at predictable intervals) as incompatible with his own corpuscular physiology.(Wesley D. Smith, 1979) Smith shows that Asclepiades thereby initiated a tradition continued by the Methodist school: Hippocrates had much to offer, but his errors were typical of the benighted past, products of a medicine that had not yet achieved theoretical clarity.(Wesley D. Smith, 1979) This position was not simple rejection but a qualified one, treating Hippocrates as a historically significant figure whose clinical observations remained useful even when his theoretical framework did not.
Celsus, writing in the second or third decade of the first century CE, presents a notably different Hippocrates from any that had come before: the father of medical science, a student of philosophy who had studied under Democritus, and the source of dogmatic medicine as a coherent tradition.(Wesley D. Smith, 1979) On Celsus’s account, Hippocrates was the first to separate medicine from general learning, establishing it as a discipline distinct from philosophy. His surgery is, as Smith notes, almost wholly a Hippocratic digest, and the Hippocratic Question (which texts are genuine) does not yet trouble Celsus’s usage.(Wesley D. Smith, 1979) Not everyone was oriented this way. The Pneumatic theorists, for all their theoretical ambition, showed no particular attention to Hippocrates; the assumption that every medical thinker in this period was necessarily a “follower” or “enemy” does not survive close examination.(Wesley D. Smith, 1979)
The first recorded statement about the authenticity of a specific Hippocratic text appears in this same period. Erotian, the first-century CE lexicographer who compiled a glossary of Hippocratic terms, stated that Prorrhetic 2 was not by Hippocrates, the earliest known instance of an authenticity judgment about a Corpus text.(Wesley D. Smith, 1979) Erotian also listed the Presbeutikos and the Epibomios logos as texts that present Hippocrates more as a patriot than as a medicine man, suggesting awareness even in antiquity that biographical texts served political rather than clinical purposes.(Wesley D. Smith, 1979) His contemporaries Dioscurides and Capiton took a different approach to the textual problem: rather than simply attributing or denying, they altered the language of Hippocratic texts to conform to the dialect of Cos, obelized passages they considered spurious, and attributed certain works to Hippocrates’ grandson.(Wesley D. Smith, 1979)
A further criterion for authenticity emerged in this period. Smith traces the conviction that the “most genuine” Hippocratic works are the least theoretical, the observational case records rather than the doctrinal treatises.(Wesley D. Smith, 1979) This preference inverted Galen’s later hierarchy and anticipated modern scholarship’s skepticism about systematizing treatises.
Rufus of Ephesus, active in the late first and early second century CE, represents a more nuanced engagement than either the Asclepiadean critique or Galenic reverence. Rufus revered Hippocrates but did not hesitate to disagree when his own clinical experience pointed elsewhere.(Wesley D. Smith, 1979) He praised Hippocrates while urging that the patient’s own testimony not be neglected, a practical corrective that implicitly acknowledged limits in the received tradition.(Wesley D. Smith, 1979) Smith notes that Rufus encountered in his own practice aggressive know-nothing Hippocrateans for whom the name had become a formula rather than a method, an early witness to the gap that had already opened between the historical physician and the ideological figure his name was being made to serve.(Wesley D. Smith, 1979)
The Biographical Legend
Almost everything traditionally “known” about Hippocrates as a person comes from pseudepigraphic letters and speeches that became part of the Corpus, published in Littre’s volume 9. The most elaborate biographical tradition was recorded in the second century CE by Soranus of Ephesus: Hippocrates was the son of a doctor named Heraclides, his mother was Phenarete, he studied under his father and then under Herodicus, Gorgias the sophist, and Democritus the philosopher, and he died at an advanced age of 104 years (Henry E. Sigerist, 1933). The nucleus of this biography dates back to the fourth century BCE in Cos itself, and by the third century BCE a version was already circulating in Egypt at Alexandria (Pormann (ed.), 2018). The legendary biographies grew by accretion around two core narrative clusters: stories of Hippocrates and the Persian king Artaxerxes (Letters 2–9) and stories of Hippocrates and the philosopher Democritus (Letters 10–18) (Pormann (ed.), 2018).
In the Artaxerxes strand of the Letters, Hippocrates is invited to the Persian court with promises of rich rewards but refuses to serve an enemy of Greece (Pormann (ed.), 2018). Jouanna preserves the texture of the refusal: when Artaxerxes I (464-424 BCE), son of Xerxes, sought Hippocrates’ services to end a pestilence afflicting his army, Hippocrates is said to have answered the envoy Hystanes that he had food, clothing, shelter, and substance enough already, that it was not proper for him to enjoy Persian opulence or save Persians from disease “since they are enemies of the Greeks,” and that the messenger should fare well (Jouanna, 1999) (Jouanna, 1999). The refusal of Artaxerxes had become a stock theme by the second century CE: Galen, in his portrait of the ideal physician, wrote that the excellent physician will “disdain Artaxerxes and not be able to show himself to his view, even for a single moment” (Jouanna, 1999). Jouanna treats the refusal as plausibly historical at least in spirit: it accords with the attitude of Hippocrates’ forebear Hippolochus, who according to the Speech of the Envoy incited the revolt of Cos against the Persians, and it occurred when the island had been delivered from Persian domination and belonged to the Athenian confederation (Jouanna, 1999). Refusing the Persian king should also be set against the older example of Democedes of Croton, the foremost physician before Hippocrates, who had successfully treated King Darius and Queen Atossa but only after becoming the Persian king’s prisoner and slave (Jouanna, 1999). He treats Prince Perdiccas of Macedonia, quickly diagnosing lovesickness for one of his father’s concubines, restores the prince to health, and then declines to remain as court physician (Pormann (ed.), 2018). Jouanna is more guarded about the Perdiccas story than the Letters are: a closely parallel anecdote attaches to the great Hellenistic physician Erasistratus, who is said to have diagnosed King Antiochus’ lovesickness for Stratonice, the wife of his father Seleucus I, and the sameness of the two narratives casts doubt on the underlying tale (Jouanna, 1999). What does have independent support is the bond between the Asclepiads and the Macedonian royal house: the Speech of the Envoy confirms ancestral ties of hospitality, and Hippocrates’ son Thessalus went on to become physician to Archelaus, Perdiccas’s bastard son and successor (Jouanna, 1999). The plague episode in which Hippocrates’ pupils, rather than himself, quell disease among the Illyrians and Paeonians (Pormann (ed.), 2018) also has a fuller form in the Presbeutikos: when plague was running through barbarian lands north of Illyria and Paeonia, the kings sent for Hippocrates from Thessaly because of his reputation; he questioned their messengers about the heat, winds, mist, and other unusual conditions area by area, told them he could not come, and then arranged as quickly as possible to inform the Thessalians how to protect themselves against the evil that was coming (Jouanna, 1999). Jouanna emphasizes that this is not the famous Athenian plague of Thucydides: the Hippocratic plague came from the north rather than the south and occurred after 421, probably during 419-416, whereas Thucydides’ plague originated in Ethiopia and reached Athens through Piraeus in 430-429 (Jouanna, 1999). He also observes a problem with the Hippocratic tradition itself: no source other than the Presbeutikos and its dependents records a plague in Greece in 419-416, and Thucydides, alert to such matters, does not speak of one, which calls the authenticity of the Hippocratic story into question even though the framework around it draws on other corroborated material (Jouanna, 1999). A pithy exchange recorded by Stobaeus in the fifth century CE, not derived from the Letters or any other known source, has someone urging Hippocrates to go to the king Xerxes on the grounds that “he is a good king,” to which Hippocrates replies, “I have no need of a good master” (Pormann (ed.), 2018).
The Perdiccas tale proved remarkably durable. It was retold repeatedly throughout the Imperial age, appeared in reworked form in a fifth-century Latin poem by Dracontius (Aegritudo Perdicae), and survives in a third-century mosaic from Algiers depicting Hippocrates testing the young prince’s pulse (Pormann (ed.), 2018). The philosopher Posidonius is credited with the version of the twins anecdote in which Hippocrates diagnoses two men as twins by recognising their bodily similarity — a story known through Augustine’s later citation and illustrating how Hippocratic material circulated through philosophical rather than medical channels.(Pormann (ed.), 2018) The Late Life of Bruxelles, one of several biographical compilations whose circulation extended into the Byzantine period, adds the claim that Hippocrates brought many books back from Persia and Egypt during his travels, a detail that assimilates him to the later figure of the learned physician who synthesizes oriental and Greek wisdom — a biographical topos that says more about the period of composition than about the historical Hippocrates.(Pormann (ed.), 2018)
In the Democritus strand, Hippocrates encounters the philosopher who suffers continuous laughter for unknown reasons. He concludes that Democritus is not mad but laughing at human vanity as a genuinely wise man — an episode with Cynic overtones that draws on philosophical rather than medical sources, making Hippocrates effectively the sidekick of Democritus (Pormann (ed.), 2018). Diogenes Laertius adds a separate anecdote in which Democritus outperforms Hippocrates diagnostically: he identifies the source of a cup of milk as a black she-goat and, after a maidservant accompanied Hippocrates one day, greets her the next morning as “woman” rather than “maiden” (Pormann (ed.), 2018).
Temkin’s analysis of the literary form of the Pseudepigrapha clarifies what the texts were doing. By the first or second century CE, the legendary stories had been given fixed literary form in two Greek works: the Pseudepigrapha themselves, which handled Hippocrates in a novelistic fashion through letters and speeches, and the biographical Vita attributed to Soranus, treated in antiquity not as fiction but as a collection of documents with historical value.(Temkin, 1991) The three main thematic clusters of the Pseudepigrapha — the invitation from King Artaxerxes, the invitation from the Abderites leading to the meeting with Democritus, and the fate of Cos as related to Hippocrates and his family — provided the narrative skeleton around which other biographical materials were organized.(Temkin, 1991) The Artaxerxes correspondence showed a Hippocrates who refused to help Persia because he had “no right to share the wealth of the Persians or to liberate from disease barbarians who are the enemies of the Greeks” — an expression of Panhellenic philanthropy deliberately bounded by national loyalty.(Temkin, 1991) The encounter with Democritus ended as a philosophical victory for the Cynic position and a defeat for Hippocrates: Democritus, the laughing philosopher, convinced him that human life was folly, leaving open the troubling question of whether ordinary human life was worth treating and saving only to be left to its follies.(Temkin, 1991) One text in the collection, a letter by Paetus to Artaxerxes, described Hippocrates in explicitly divine terms: descendant of Asclepius and Hercules, possessed of a divine nature, who purged the earth of fierce diseases as Triptolemus once spread the gifts of Demeter — “father of health, savior, and leader of the science befitting a god.”(Temkin, 1991) The Vita, by contrast, showed almost no interest in the content of Hippocratic medical doctrine, noting only the difficulty of identifying genuine works while devoting sustained attention to biographical exploits — a distribution of interest that Temkin reads as reflecting a public more concerned with the life of a great man than with his medical theories.(Temkin, 1991)
A fourth-century BCE Delphic inscription concerning the Coan and Cnidian Asclepiads has been pressed into service as epigraphic corroboration of the biographical tradition. The French epigrapher Bousquet proposed a reading of this inscription that would link the Asclepiad guild directly to Hippocratic history, but Smith notes that Bousquet’s theory requires “considerable suspension of disbelief” and that the inscription’s relevance to the Hippocratic Question remains disputed.(Wesley D. Smith, 1979)
These texts relate his deeds — Athenian plans to attack Cos averted by Hippocrates’s diplomacy, his service curing plagues, his patriotic refusal to serve barbarian royalty, his famous meeting with Democritus the laughing philosopher (Wesley D. Smith, 1979). Smith considers virtually all of this fantasy. The pseudepigrapha, he argues, probably concocted their biography from inferences drawn from the Corpus itself — especially from the case records of the Epidemics, which mention place names and travel itineraries from which a mobile life could be inferred (Wesley D. Smith, 1979).
Smith goes further: there is no ascertainable relation between the Corpus and the sons, son-in-law, grandsons, father, or grandfather attributed to Hippocrates. The genealogy itself has no authority that can be ascertained (Wesley D. Smith, 1979).
A counter-tradition also circulated. Varro told a version in which Hippocrates copied the god’s prescriptions from patients’ votive tablets at the temple, kept the information for himself, and started clinical medicine when the temple burned (Wesley D. Smith, 1979) (Wesley D. Smith, 1979). The anti-Hippocratic legends served different interests but shared the same evidentiary base: none.
Among the more curious byproducts of biographical elaboration is a pseudo-Hippocratic letter addressed to King Ptolemy, preserved in numerous manuscripts but never edited — apparently because it is historically impossible that the fifth-century BCE Hippocrates wrote to the third-century BCE Ptolemy (Pormann (ed.), 2018). The accumulation of such texts is a reminder that the image of Hippocrates underwent numerous mutations across different communities: the “Christian” Hippocrates differs sharply from the one projected by Galen and recovered during the Renaissance (Pormann (ed.), 2018).
The early medieval Latin West compounded these confusions. Isidore of Seville, writing around 600 CE, identified Hippocrates’ father as Asclepius himself — “Hippocrates, born on the island of Cos and whose father was Aesculapius, restored it to light” — a blunder that Temkin sees as unsurprising given the collapse of historical memory; around the same time, Marcellus of Bordeaux cited letters of Hippocrates purportedly addressed to King Antiochus (a Seleucid of the third or second century BCE) and to Maecenas (a Roman patron of the first century BCE) — a chronological impossibility of five centuries that passed without comment.(Temkin, 1991)
Democritus of Abdera had a considerable and long-lasting influence on medicine, and an Alexandrian catalogue lists his works on prognosis and dietetics (Nutton, 2023). Schiefsky documents that scholars have long alleged Democritus’s influence on On Ancient Medicine, particularly regarding the account of the gradual development of medicine from necessity and the use of krasis and dynamis to explain humoral effects (Schiefsky, 2005).
Hippocrates and Madness
The Hippocratic approach to mental disturbance is among the most discussed and most misrepresented aspects of the Corpus. The treatise On the Sacred Disease is misnamed: its entire argument is a refutation of its title. It constituted what Andrew Scull calls “a full-blooded assault on attempts to invoke magical and religious explanations” of epilepsy and related disturbances (Andrew Scull, 2015). The text argues that epilepsy “appears to me to be nowise more divine nor more sacred than other diseases, but has a natural cause from which it originates like other affections.” This rejection was part of a broader competitive move: the Hippocratics were differentiating themselves from temple medicine, the practitioners of healing shrines dedicated to Asclepius, who relied on spells, charms, and purification rites (Andrew Scull, 2015).
Temkin, whose monograph The Falling Sickness remains the standard history of epilepsy, identifies On the Sacred Disease as “not only the first monograph on epilepsy that we possess, but also one of the most important documents extant of magic beliefs and practices in ancient Greece,” and notes that its author extended the argument well beyond epilepsy: “not only epilepsy, but all mental diseases as well, can be explained by disturbances of the brain.”(Temkin, Owsei, 1971)(Temkin, Owsei, 1971) The text’s authenticity was, however, never secure. Galen expressed doubt, and when the works of Hippocrates were edited at the start of the sixteenth century, a note was found in several manuscripts stating that Galen had thought the work spurious and “not congruous with the style and acumen of Hippocrates” — a challenge to its canonical status that added to Renaissance debates about which writings were genuinely Hippocratic.(Temkin, Owsei, 1971)
The Hippocratic naturalistic account of madness located its seat in the brain. The Corpus asserts that from nothing else but the brain come joys, delights, laughter, and sports, as well as sorrows, griefs, despondency, and lamentations, and that the head rather than the heart is where madness lurks. The mechanism was humoral: too much blood warmed the brain and produced nightmares and terrors; too much phlegm produced a quiet mania; madness resulting from bile caused shouting, mischief, and agitation (Andrew Scull, 2015). The very word “melancholy” (melas, black + cholê, bile) embeds Hippocratic humoral theory into the vocabulary of emotional suffering, a linguistic trace that persisted across centuries into modern clinical language.
Van der Eijk’s reading of On the Sacred Disease refines the dominant picture in two ways that matter for how the text’s “naturalism” should be described. First, the author does not simply abolish the divine character of the disease; he reinterprets it. As van der Eijk puts it, the author
does not reject the divine character of the disease, but modifies the sense in which this disease (and, as a consequence of this conception, all diseases) may be regarded as divine: not in the sense that it is sent by a god, for example as a punishment, and is to be cured by this same god, but that it shares in the divine character of nature in showing a fixed pattern of cause and effect and in being subordinated to what may perhaps be called, somewhat anachronistically, a natural ‘law’ or regularity.(van der Eijk, Philip J., 2005)
There is, in fact, a textual ambiguity about why diseases are called “divine” at all in the treatise: one strand identifies the divine with climatic causes (heat, cold, winds), another identifies it with the phusis (regular nature) the disease has in common with other phenomena.(van der Eijk, Philip J., 2005) Second, the author also expresses, alongside this naturalised theology, an unmistakable personal religious conviction in gods who purify human beings of their moral transgressions, “who are worshipped in temples by means of prayer and sacrifice.”(van der Eijk, Philip J., 2005) He is, on this reading, drawing a careful boundary between magic, where “man himself performs the purification by making the gods obey his incantations (epaōidai),” and religion, in which “man approaches the gods in the temple and prays for help, but it is the god who performs the purification.”(van der Eijk, Philip J., 2005) Van der Eijk’s overall verdict is that the author’s primary aim is “the disengagement of epilepsy from the religious domain (which implies claiming it as an object of medicine)”; the corrective criticism of the idea that diseases are sent by gods is “subordinated to a primarily medical purpose,” not the proclamation of a new naturalistic theology.(van der Eijk, Philip J., 2005) The unresolved tension between the author’s belief in cleansing gods and his statements about the divine character of disease is, on this reading, “characteristic of religious thought” rather than evidence of confusion.(van der Eijk, Philip J., 2005)
The encephalocentrism the treatise actually defends is more nuanced than later doxography acknowledged. The author sets out the core claim plainly: “I believe that the brain is the most powerful part in a human being. So long as it is healthy, it is the interpreter of what comes to the body from the air. Consciousness is provided by the air … [The other parts] carry out what the brain knows … it is the brain which is responsible for all these.”(van der Eijk, Philip J., 2005) But within this scheme he distinguishes two faculties that are not coterminous. Phronēsis, “consciousness,” runs throughout the body in proportion to the air it receives; sunesis (understanding) and diagnōsis (discriminating thought) are restricted to the brain because they require a degree of purity and precision that contact with other organs disrupts.(van der Eijk, Philip J., 2005) The Hippocratic On Regimen takes a different course again, treating the soul as a material entity composed of fire and water in proportion: the soul moves through “passages” (poroi) in the body and during sleep withdraws to a “home” (oikos) the author declines to locate.(van der Eijk, Philip J., 2005) Van der Eijk’s broader cautionary point about these texts is that the standard tripartition of ancient views (encephalocentric, cardiocentric, haematocentric) is itself “a product of schematisation”; only the authors of On the Sacred Disease and On the Heart commit to a single anatomical seat, and On the Heart is “presumably post-Aristotelian” and is the only ancient text that explicitly puts gnōmē in the left ventricle.(van der Eijk, Philip J., 2005) The three explanations of epilepsy that the medical tradition produced (in On the Sacred Disease, phlegm blocks pneuma at the brain; in On Breaths, air disturbs the blood; in Aristotle, food vapours obstruct the heart’s cooling) illustrate how thoroughly each author’s prior commitment about the seat of cognition shaped the pathology he proposed.(van der Eijk, Philip J., 2005)
Hippocratic medicine also constructed hysteria as a female-specific condition rooted in the womb: the womb as the origin of all diseases of women, with its tendency to wander internally in search of moisture producing a great variety of organic complaints (Andrew Scull, 2015). This account was reworked by Galen and other Roman commentators to produce the classical accounts of hysteria that would dominate Western medicine for more than a millennium, though Soranus and Galen both disputed whether the womb could literally wander while accepting it as the organ of origin for hysterical symptoms.
The naturalistic ambition of Hippocratic psychiatry was real and historically consequential. But Scull makes clear that this ambition coexisted with a competitive social context rather than arising from neutral scientific observation: the same texts that argue for natural causation of madness are also, simultaneously, arguments against rival practitioners whose livelihoods depended on supernatural explanations (Andrew Scull, 2015).
The Hippocratic Body: Pulse, Muscle, and Anatomical Seeing
The Hippocratic body was not the body familiar from later anatomical medicine. Shigehisa Kuriyama’s comparative study of Greek and Chinese medicine reveals that several categories now taken as natural givens were, in Hippocratic practice, absent or radically different in meaning.
The pulse is the clearest case. In Hippocratic writings, the word sphygmos (which Galen and Rufus would later use for the pulse) did not name a constant physiological rhythm. It named a pathological throbbing associated with fevers and inflammations, one sign among others on a continuum with palmos (palpitation), tromos (tremor), and spasmos (spasm). The verb sphyzein referred not to the continuous activity of the arteries but to the throbbing that sometimes accompanies acute disease (Kuriyama, Shigehisa, 1999). A philological detail makes the absence of the unified pulse concept concrete: several Hippocratic passages use the plural sphygmoi where later medicine would use a singular. Diseases of Women speaks of “the pulses quivering, faint, and fading against the hand”; Epidemics 4 records that “the pulses of Zoilos the carpenter were trembling and obscure.” Sphygmoi named throbbings in their concrete multiplicity; the idea of a single, unified pulse had not yet crystallized (Kuriyama, Shigehisa, 1999).
The term mys (muscle) appears nowhere in Homer, Herodotus, Thucydides, or any of the dramatists (Kuriyama, Shigehisa, 1999). Plato’s Timaeus speaks extensively of flesh and sinews but makes no mention of muscles (Kuriyama, Shigehisa, 1999). Hippocratic treatises referred instead to sarks (flesh) and neuroi (tendons) (Kuriyama, Shigehisa, 1999). Muscle-consciousness as a distinct category of anatomical knowledge emerged only gradually between Hippocrates and Galen (Kuriyama, Shigehisa, 1999).
Hippocratic indifference to systematic anatomy reflects a broader historical pattern. Kuriyama notes that major medical traditions (Egyptian, Ayurvedic, and Chinese) all flourished for thousands of years without privileging the inspection of corpses. Even the Hippocratic Corpus, for all its reputation as the source of Western medical rationalism, manifests scarce interest in anatomical inquiry (Kuriyama, Shigehisa, 1999). There are innumerable ways to know the body, and the Greek privileging of dissection was historically anomalous rather than medically necessary.
Where Hippocratic medicine did attend carefully to the body’s surface and internal connections, it operated with a topological logic rather than an anatomical map. Bloodletting provides the clearest example. The approximately seventy references to letting blood in the Hippocratic Corpus earn it only a modest therapeutic role, and no treatise develops an extended theory of phlebotomy. The attribution of bloodletting’s later centrality to Hippocratic authority is, as Kuriyama documents, a myth: bleeding became a pillar of Western medicine later, through Galen (Kuriyama, Shigehisa, 1999). But when the Corpus does prescribe bloodletting, it specifies sites: to relieve liver afflictions, let blood from the right elbow; for the spleen, from the left elbow; for back pain, from veins on the outside of the ankles; for testicular pain, from the inside of the ankles. Galen himself asserts that Hippocrates and “the most celebrated physicians” promoted this practice of topological bleeding, choosing specific sites based on perceived vascular connections to distant body parts (Kuriyama, Shigehisa, 1999).
The Airs, Waters, Places treatise extends bodily thinking into environmental and political territory. It argues that the well-articulated, taut bodies of Europeans reflect the violent seasonal variation of their climate, which forces individual endurance, while Asian bodies (less articulated, flabbier) reflect the uniform climates that breed softness. “Uniformity engenders slackness, while variation fosters endurance in both body and soul” (Kuriyama, Shigehisa, 1999). The body’s internal organization, on this account, mirrors the character of its environment.
Hippocratic wind theory similarly reveals how Greek medicine structured its explanations. In Airs, Waters, Places and On the Sacred Disease, winds are understood through their qualities (dry or moist, hot or cold) as distant exciting causes that act on the body by triggering imbalances within the humoral system. The wind does not invade; it is a remote cause that operates through the body’s own constitution. This contrasts with Chinese medical wind theory, where evil winds (xiefeng) are defined not by quality but by timing: proper winds blow from the right direction in the right season, and deviation from seasonal regularity is itself pathological (Kuriyama, Shigehisa, 1999).
Melancholia in the Hippocratic Tradition
The Hippocratic Corpus provides the first systematic account of melancholia in Western medicine. The core definition that the Corpus established — and that Galen would later quote as authoritative — held that “all patients who are troubled by melancholia without cause in their activities are seized by fear or despondency” (Radden, Jennifer (ed.), 2000). This is a definition anchored in affect: the disorder is characterized not by any particular delusion or behavior but by persistent fear and sadness experienced without identifiable external cause. Galen, writing in the second century CE, cited this formula from the Hippocratic tradition to establish the clinical baseline for melancholic presentations, and it remained the reference point for Western accounts of the condition for over a millennium.
The Hippocratic pseudo-Aristotelian tradition also contributed a specific theory of melancholic temperament. The Problemata (ca. 300 BCE), attributed to Aristotle’s school, contains one of the earliest accounts of the thermal properties of black bile that would anchor all subsequent humoral theory of melancholia: black bile, unlike other humors, could be either naturally cold or heated by disease, and this thermal variability explained the range of melancholic presentations from stupor and torpor to agitation and mania (Radden, Jennifer (ed.), 2000). This thermal flexibility was the conceptual resource that made black bile theory so durable: it could explain both the depressed and the excited presentations of the same disorder by attributing different thermal states to the same substance.
On Ancient Medicine and Medical Epistemology
On Ancient Medicine (in Greek, Peri Archaies Ietrikēs; conventionally abbreviated VM for the Latin Vetusta Medicina) is among the earliest and philosophically most demanding texts in the Hippocratic Corpus. Where most Hippocratic treatises practice medicine, VM theorizes it — arguing at length about what medicine is, where its knowledge comes from, and why it does not need philosophy to legitimate it. Mark Schiefsky’s 2005 Cambridge commentary is the fullest modern analysis of the text, and his reading transforms VM from a simple manifesto of empiricism into a sophisticated intervention in fifth-century debates about the nature of craft knowledge.(Schiefsky, 2005)
The Anti-Hypothesis Argument
The treatise opens with a direct polemical attack. Certain doctors and sophists, VM’s author complains, have attempted to found medicine on hypotheseis — one or two elemental principles such as hot, cold, wet, or dry — claiming that these abstractions are the primary causes of disease and that treatment consists in applying the opposite quality.(Schiefsky, 2005) Schiefsky shows that the word hypothesis here carries its etymological sense of “foundation” or “basis”: the opponents are trying to give medicine a new systematic starting point borrowed from Presocratic cosmology, specifically from the tradition running through Empedocles.(Schiefsky, 2005) Their motivation was respectable — they wanted to prove that medicine was a genuine technê, a systematic art with rational foundations, rather than mere craft routine or luck.(Schiefsky, 2005)
The author’s response is that medicine does not need an empty postulate, as it is already a genuine art.(Schiefsky, 2005) Schiefsky argues that both the author and his opponents share the same underlying ambition: establishing medicine as a genuine technê requiring systematic knowledge of the human constitution and the causes of health and disease.(Schiefsky, 2005) The disagreement is about method, not about whether medicine should be systematic.(Schiefsky, 2005)(Schiefsky, 2005)
Schiefsky identifies the shared underlying impulse of VM’s opponents across both the early and late portions of the text: they draw on Presocratic cosmology — the “inquiry into nature” beginning with Thales and running through Empedocles, Anaxagoras, Diogenes of Apollonia, and Democritus — to give medicine the theoretical foundation that would qualify it as a genuine technê (Schiefsky, 2005). The reference to Empedocles in chapter 20 is specifically to his embryological cosmogony and his four elemental roots, for which Empedocles’ own term (rhizoma, root) indicates these elements are embedded within a larger cyclical framework governed by Love and Strife (Schiefsky, 2005). This is not mere academic cosmology: Schiefsky demonstrates that Empedocles was the first thinker to develop a clear concept of elemental constituent, with unchanging and indestructible roots that combine and separate to produce all change (Schiefsky, 2005).
The opponents’ elemental framework also fails on practical grounds. VM chapter 15 presses the embarrassing question: can they identify a food that is purely hot, or purely cold, with no other quality mixed in? They cannot.(Schiefsky, 2005) Meanwhile, VM chapter 16 argues that hot and cold are actually the least powerful of bodily forces precisely because they automatically counteract one another in the body without any medical intervention — feverish chills resolving spontaneously into warmth — which Schiefsky reads as an early implicit argument for the body’s own healing powers.(Schiefsky, 2005) (Schiefsky, 2005) This argument is made explicit in chapters 17-18: the persistence of fever in serious diseases like pneumonia shows that heat is not the sole cause of harm but an auxiliary power accompanying a primary causative humor (Schiefsky, 2005). Diseases do not cease when hot changes to cold; they cease when unconcocted humors undergo pepsis (coction) and krasis (blending) (Schiefsky, 2005). The real causes of disease, the author insists, are specific unconcocted humors — salty, bitter, acid, astringent substances — which cause harm when they separate from the body’s normal blend. These humors are addressed not by opposing their elemental quality but by the process Schiefsky calls pepsis (coction): blending and ripening, the restoration of the mixture.(Schiefsky, 2005)
VM chapter 14 presents the humoral theory directly: the human body contains a blend of fluid substances — salty, bitter, sweet, acid, astringent, insipid, and many more — that remain benign when mixed together but cause pain and disease when one separates and concentrates on its own (Schiefsky, 2005).
Medicine as Technê and the Problem of Precision
Schiefsky argues that by the end of the fifth century BC there had developed a widespread conception of an “exact techne”: an art that could achieve full akribeia by using precision tools to make exact quantitative measurements.(Schiefsky, 2005) The earliest known instance of the adjective akribes occurs in a medical context: a fragment of the sixth-century BC poet Arctinus of Miletus that describes the different abilities of the Homeric physicians Machaon and Podaleirius, suggesting that precision was closely associated with medicine from its earliest literary attestations.(Schiefsky, 2005)
VM is acutely aware that medicine cannot fully meet this standard. Chapter 9 admits plainly that the doctor’s art “requires greater precision” than simple dietary adjustment, but then acknowledges that the only available measure (metron) is “the feeling of the body” — the patient’s own felt response to treatment.(Schiefsky, 2005) There is no number, no weight, no instrument that can supply the precision that rulers and scales provide to the carpenter. Schiefsky’s commentary establishes that this phrase refers specifically to the patient’s perceived reaction as a clinical tool, the doctor’s sole standard for judging whether a treatment is working.(Schiefsky, 2005) Schiefsky refutes the scholarly reading that equates this with Protagoras’s relativism: the author does not say that a treatment is efficacious because the patient perceives it to be so. The patient’s reaction is the tool for judging efficacy, not the criterion that constitutes it (Schiefsky, 2005).
This acknowledgment of imprecision might seem to undermine medicine’s claim to be a genuine art. VM’s author turns the argument around. Medicine has advanced “by means of reasoning from profound ignorance close to perfect accuracy” — and this trajectory of progressive improvement, not some currently achieved perfection, is what makes medicine admirable.(Schiefsky, 2005) The doctor who makes only small errors deserves high praise; perfection is rarely seen.(Schiefsky, 2005) This is what Schiefsky identifies as the concept of hikanon akribeia — sufficient or appropriate precision: medicine need not aspire to the precision of mathematics to be a genuine art; it needs only the degree of precision its subject matter makes possible. The claim anticipates Aristotle’s Nicomachean Ethics, which argues that each art should be judged by the standards appropriate to it rather than by the standards of a different discipline.
The Dietetic Origin of Medicine
One of VM’s most striking arguments is its account of medicine’s historical origins. The author traces medicine back not to divine inspiration, priestly tradition, or theoretical discovery, but to ordinary dietary observation. Ancient humans, he argues, began from a brutish diet identical to that of animals; observing that such foods caused suffering and that modified, prepared foods caused less, they developed the art of cooking — and from cooking, by the same method, medicine.(Schiefsky, 2005) Schiefsky reads this as a rhetorical strategy as well as a historical claim: by asserting that the discovery of cooking and the discovery of medicine are “one and the same,” the author makes medicine intelligible to a lay audience while simultaneously elevating cooking to the status of an art with deep historical roots (Schiefsky, 2005). Schiefsky interprets chapters 3-8 as establishing a strict methodological parallel between the discovery of food preparation and the discovery of medical regimen: both begin from the observation that different individuals respond differently to the same foods, and both proceed by systematically adjusting preparation to fit individual constitutions.(Schiefsky, 2005)
This argument serves several purposes at once. It grounds medicine’s epistemic authority entirely in experience — not in cosmological speculation about how the world began, but in the accumulated observation of how bodies respond to what they consume. It also answers the charge that medicine without elemental hypotheses is unsystematic: the author’s own humoral theory, which proposes that the body contains a large number of fluid substances (sweet, salty, bitter, acid, astringent, and many more) that remain healthy when blended and harmful when one separates and concentrates on its own, is presented as a theory derived from precisely this kind of dietary observation.(Schiefsky, 2005) The cheese passage in chapter 20 is the clearest illustration: cheese does not harm all people equally, because individuals differ in which humors predominate in their constitutions, and what is harmful to one constitution may be beneficial to another.(Schiefsky, 2005) VM’s humoral theory is deliberately more open-ended than the canonical four humors of Nature of Man; Schiefsky shows that this multiplicity is strategic, providing the explanatory flexibility that elemental reductionism lacks.(Schiefsky, 2005)
VM chapter 20 makes the methodological claim explicit: whatever sophists and doctors have written about “nature” in the Empedoclean style pertains “less to the art of medicine than to the art of writing.”(Schiefsky, 2005) Schiefsky reads this as sarcastic dismissal rather than principled contrast — the authors of cosmological theories may write fine prose, but they have produced nothing useful for practice.(Schiefsky, 2005) The counter-claim is more radical: genuine knowledge of human nature cannot be attained from any source other than medicine. This does not deny that Empedocles had philosophical insight, but it makes a strong methodological argument: the knowledge the doctor needs — how the human constitution responds to regimen — can only be built by studying what regimen does to the body, not by inferring it from elemental theory.(Schiefsky, 2005)
VM’s analogical method is a further elaboration of this empirical approach. Chapter 22 introduces a theory of bodily structures (schemata) — hollow and tapering, extended, solid and round, broad and suspended — and their capacities to attract, retain, or expel fluids. To investigate these unobservable structures, the author turns to external analogies: cupping instruments that taper from wide to narrow have been crafted precisely to attract and draw fluid from the flesh, so the bladder, the head, and the womb must work by the same structural logic (Schiefsky, 2005). Schiefsky distinguishes this controlled analogical method from Empedocles’ more speculative analogies: the VM author applies analogy only to matters where he already knows a great deal from clinical experience, so the analogy clarifies an established phenomenon rather than conjuring an invisible one from scratch (Schiefsky, 2005). The analogical method is then extended in chapter 24: the author argues that the doctor must study not only how humors blend but how they transform spontaneously on their own, using the example of sweet wine turning to vinegar as an analogue for internal humoral change (Schiefsky, 2005). Schiefsky’s commentary on chapter 22 also catalogs the specific organs the author offers as structural illustrations: the bladder, the head, and the womb attract moisture through their tapered hollow form; the spleen, lung, and breasts readily drink up what is in contact with them through their spongy porous texture (Schiefsky, 2005).
The Competitive Context and the Lay Audience
Schiefsky establishes two important features of VM’s rhetorical situation that bear on how to read its arguments. First, the text was very likely composed for oral delivery rather than as a written treatise — the author consistently uses verbs for speaking rather than writing when referring to his own presentation, suggesting a public lecture or debate context.(Schiefsky, 2005) Second, VM was aimed at a lay audience with general intellectual interests, not at specialist practitioners.(Schiefsky, 2005) Aristotle distinguishes between those with episteme (scientific knowledge) of a subject and the pepaideuemenos — the educated layperson capable of judging whether an argument’s methodology is sound. It is this second audience, Schiefsky argues, at whom VM is primarily directed.
This matters because the text’s competitive context was fierce.(Schiefsky, 2005) Hippocratic doctors competed for patients and reputation against root-cutters, drug-sellers, midwives, and the itinerant purifiers attacked in On the Sacred Disease.(Schiefsky, 2005) This competitive context motivated the development of theoretical accounts of human nature as a means of professional differentiation.(Schiefsky, 2005)
The text also participates in a broader fifth-century controversy about the relationship between art and chance (technê and tychê). Schiefsky documents that On Places in Man and On the Art articulate the same debate in closely parallel terms: medicine’s superiority over chance consists precisely in the fact that its knowledge is systematic and teachable, not dependent on luck.(Schiefsky, 2005)
Epistemological Legacy
VM’s arguments anticipate, in germinal form, the great methodological dispute between the Rationalist and Empiricist schools of medicine that would dominate Hellenistic medical theory. Schiefsky demonstrates that both the author of VM and his opponents share the framework of technê theory that Plato and Aristotle would later adopt and systematize.(Schiefsky, 2005) The Hellenistic Empiricists, who distrusted theoretical postulation and grounded medical practice entirely in clinical observation and accumulated experience, could read VM as supporting their position — its insistence that medicine has its own method independent of philosophical hypotheses resonates strongly with Empiricist polemic against the Rationalist sects. The book’s appendix on VM and medical Empiricism explores this connection, which Schiefsky treats as a historically significant reception rather than a direct line of influence.
VM also anticipates questions about causal reasoning that would later become central to medical epistemology. Chapter 21’s critique of other doctors who mistake temporal succession for causal connection — attributing a patient’s deterioration to the bath or meal that happened to precede it — represents one of the earliest formulations of the distinction between post hoc and propter hoc reasoning in clinical medicine.(Schiefsky, 2005) Schiefsky’s commentary on this passage identifies it as an early articulation of causal reasoning in clinical medicine: the author’s point is that most doctors, like lay people, blame whatever unusual activity preceded a relapse, not knowing the actual cause and perhaps depriving the patient of what is most beneficial (Schiefsky, 2005). The author’s insistence on knowing why a regimen change affected a patient, not merely that it did, implies a model of causal knowledge that goes well beyond the observational practices he praises.
Schiefsky’s commentary on VM chapter 20 refutes two common misreadings. The word historia in that chapter does not carry a merely speculative or relativist sense; it was commonly used for investigations with a solid empirical basis, and the author clearly regards the knowledge he calls historia as attainable through the right kind of inquiry (Schiefsky, 2005). Nor does the pros (“in relation to”) construction throughout chapter 20 express relativism: it conveys a relational framework in which the doctor must be able to coordinate an individual patient’s constitution with the components of their regimen — a systematic, mappable relationship rather than a statement that treatment effects are relative to the perceiver (Schiefsky, 2005). On the Empedoclean side, Schiefsky draws on Aristotle’s critique (Parts of Animals 640a18–22) to clarify the explanatory weakness of Empedocles’s approach: Empedocles derived the present characters of animals from how things happened during their coming-to-be, whereas VM insists that coming-to-be must be explained by substance, not substance by coming-to-be (Schiefsky, 2005) (Schiefsky, 2005). The method of analogical inference in VM chapter 22 also presupposes existing knowledge: the author already knows the hollow-tapering morphology of the bladder, head, and womb and uses that established knowledge as the starting point for analogical extension, not as a conclusion conjured from the analogy alone (Schiefsky, 2005). And the cheese passage finds independent corroboration in Morbus IV 35, which describes how cheese or pungent foods immediately run up to the mouth and brain in susceptible individuals — confirming that the sensitivity of specific constitutions to specific foods was a widely recognised clinical datum, not merely a rhetorical example (Schiefsky, 2005).
By Plato’s time, Hippocrates’ method of relating individual constitutions to types was recognized outside medicine. In the Phaedrus, Socrates describes the ideal scientific rhetorician as one who proceeds exactly as Hippocrates does: classifying types of soul and coordinating each type with the speech appropriate to it.(Schiefsky, 2005) This suggests that what made Hippocrates symbolically significant to the fourth century was not a specific doctrinal position but a method — the systematic, individualized relational analysis of person to regimen, soul to speech, constitution to treatment — that could be abstracted from medicine and applied elsewhere.
Legacy
Hippocrates became the patron saint of Western medicine not because of what he actually wrote or taught but because he was useful. Every reformer, every tradition, every faction could claim him. The Oath alone has been scrutinised in ethical debates on abortion, and the US Supreme Court judgment in Roe v. Wade references scholarly debates about its meaning (Pormann (ed.), 2018). National Socialist physicians invoked Hippocrates — alongside Paracelsus — to justify their actions, arguing that doing no harm to the individual body took second place to doing no harm to the social body as understood through Nazi racial ideology (Pormann (ed.), 2018). Scribonius Largus in the first century CE invoked the Hippocratic Oath as a professional code analogous to a soldier’s oath of allegiance, establishing a duty to heal and never to harm as the foundation of the medical professio (Nutton, 2023). Galen claimed Hippocratic precedent for recognizing stress-related illness and extending the physician’s role into moral counsel (Nutton, 2023). He also claimed that his skill in prognosis — the art of predicting the course of disease — was a recovery of a lost Hippocratic art (Nutton, 2023).
The Hippocratic Oath
The Hippocratic Oath is the most famous document in medical ethics, but Karl-Heinz Leven’s contribution to the Cambridge Companion argues that it has been systematically misunderstood. Its injunction “to help or at least to do no harm” — often rendered as the Latin primum non nocere — was not formulated in those exact words in any ancient text, though the principle is present in the Corpus, notably in Epidemics I (Pormann (ed.), 2018). More striking is the document’s reception history: the Oath became famous and widely cited only from the first century CE onward; before that period it was largely unknown or ignored in the medical literature (Pormann (ed.), 2018). Galen does not mention the five principal Hippocratic deontological treatises (Oath, Law, Decorum, Precepts, Physician) in his extensive writings on Hippocrates — suggesting they were not considered authentically Hippocratic in the second century CE (Pormann (ed.), 2018).
Leven argues that the Oath is a late and anomalous document, probably not composed during Hippocrates’ lifetime in the fifth century BCE, and may reflect a minority Pythagorean or sectarian medical tradition rather than mainstream Greek medical ethics (Pormann (ed.), 2018). Pormann later calls it a Renaissance invention in practical terms (Pormann (ed.), 2018). In ancient Greece, there was no system of medical licensing or formal credentialing; a physician’s reputation — built through demonstrated competence and success in prognosis — was his only professional capital (Pormann (ed.), 2018). The deontological treatises Decorum and Precepts (first to second century CE) reflect Stoic and Epicurean philosophical influences and represent a later, more philosophically sophisticated ethical tradition than the Oath itself, with which they were not originally connected (Pormann (ed.), 2018). The concept of philanthrōpíē (love of humanity) as a medical virtue appears in Precepts, where it forms the ethical counterweight to the physician’s claim to technical skill (philotechnia) (Pormann (ed.), 2018).
Despite this complicated origin, the Oath has been repeatedly adapted across centuries. Its clauses were modified to suit changing sensibilities: the religious introduction was dropped, the injunction to refuse lethal drugs was reinterpreted, and from the 1960s onward the prohibition of abortive pessaries was reclaimed as a statement on abortion — an interpretation that conflated two different concerns, one about controlling a dangerous drug and one about a specific clinical procedure (Pormann (ed.), 2018). National Socialist Germany is an extreme instance of this re-appropriation: physicians claimed to honor the Oath while redefining “harm” at the level of the social body rather than the individual patient (Pormann (ed.), 2018). After the Second World War, the Oath’s standing recovered rapidly: the Geneva Declaration of 1948 adapted its language to post-war concerns, and the number of medical schools in the United States, Canada, and the United Kingdom using some variant of it rose substantially (Pormann (ed.), 2018).
Mattern’s analysis of Galen’s rhetorical strategies clarifies the mechanism of this appropriation. Galen looked to what he called the palaioi — “the ancients,” especially Hippocrates, Plato, and Aristotle — as the authoritative sources of medical tradition, expending enormous energy distinguishing genuine from spurious Hippocratic treatises and treating the genuine Hippocrates as virtually infallible.(Mattern, 2008) But this reverence was productive rather than merely deferential: by presenting his own innovations as recoveries of Hippocratic wisdom, Galen converted his originality into orthodoxy and his rivals’ practices into deviations from an established canon.
The sheer scale of Galen’s engagement with Hippocrates is striking. “Galen mentions Hippocrates more than 2,500 times in his surviving works… Galen was like early Christian exegetes who expanded on biblical texts and altered their meaning with their interpretations. The genuine Hippocrates, in Galen’s work, is laconic, often enigmatic, and virtually never wrong; but Galen did not consider all works transmitted in the Corpus to be genuine.”(Mattern, 2013) This last qualification was crucial: by distinguishing genuine from spurious texts, Galen claimed the authority to define what Hippocrates actually taught, which in practice meant selecting the texts that most supported his own positions.
Galen’s identification with Hippocrates extended beyond doctrinal claims to a projected philosophical identity. “Galen continued to seek education from philosophers throughout his life and considered himself a philosopher, as well as a physician. He long argued that all truly educated doctors were philosophers and that Hippocrates had been a philosopher; he wrote philosophical treatises on logic and ethics and a brief work That the Best Physician is Also a Philosopher; he boasts of his reputation as a philosopher, which is attested independently of his works.”(Mattern, 2013) In this self-portrait, Hippocrates serves as the warrant for the claim that philosophy and medicine are inseparable — a claim that supports Galen’s own aspirations to be both.
On the specific question of humoral doctrine, Mattern identifies the decisive Hippocratic text. “The Hippocratic treatise The Nature of Man is the most coherent and explicit description of a humoral doctrine… identifying no less, or more, than four humors. The new humor — the one lacking in other Hippocratic texts… was black bile. The other humors were blood, phlegm, and yellow bile, and all together they were the essential components of man, whose health depended on their proper balance. Linked to the four humors were the four elemental qualities of hot, cold, wet, and dry.”(Mattern, 2013) Aristotle attributed The Nature of Man not to Hippocrates but to Polybus; Galen accepted it as genuinely Hippocratic. That attribution was the foundation on which Galen built his humoral system.
Galen’s stance toward Hippocrates was also his stance toward intellectual allegiance in general. “Throughout his life Galen vigorously proclaimed his independence from any sect. This intellectual independence he attributed to the influence and advice of his father, who warned him not to align himself with any tradition but to choose the best ideas from each… ‘I consider,’ he writes, making his point sharply, ‘those who name themselves Hippocrateans or Praxagoreans or after any man at all to be slaves.’”(Mattern, 2013) The paradox is deliberate: Galen invoked Hippocratic authority to legitimize his independence from Hippocratic authority. Naming oneself a Hippocratean was slavish; being like Hippocrates, in the deepest sense, meant refusing to be anyone’s follower.
Mattern also provides a systematic analysis of the Hippocratic Epidemics as a narrative genre rather than simply a clinical record. These books — composed largely of case histories characterized by minimalist prose, focus on specific observations, effacement of the author, and day-by-day chronological structure — functioned not as personal patient records but as teaching tools, ways for physicians to share experiences and illustrate general points in debate or instruction.(Mattern, 2008) The patient roster in books I and III is socially broad (both sexes, all ages, slaves, athletes, craftsmen), and more than half the patients die — a profile very different from Galen’s own case narratives, which are far more selective in who appears and almost never record fatal outcomes as straightforward failures.(Mattern, 2008) The Epidemics represent a style of clinical documentation organized by humoralist theories linking disease to weather and seasons, with particular attention to the periodicity of fevers.(Mattern, 2008)
Nutton characterizes his own book as “the first anti-Galenic history of ancient medicine,” deliberately delaying well-known texts and introducing unfamiliar figures to counter Galen’s dominance of the narrative (Nutton, 2023). His most striking conclusion about the period Hippocrates inhabited is its diversity: there was no single medical tradition even in Hippocrates’s time, and uniformity remained only a distant hope in Galen’s day (Nutton, 2023).
The Hippocratic Corpus in the Renaissance and After
David Cantor, in the chapter on Western medicine since the Renaissance in the Cambridge Companion, shows that the earliest printed collections of Hippocratic writings (from 1476) were rarely produced without Galen’s commentaries, and that only texts available through Galen’s manuscripts were included. A complete Latin printed edition appeared in 1525, followed by the first complete Greek edition in 1526 (Pormann (ed.), 2018). The process of disentangling Hippocrates from Galen took the better part of a century. Vivian Nutton argues that what Cantor calls “our modern picture” of Hippocrates was first constructed in the 1560s, with roots in the development of new medical syllabi at Bologna and Montpellier at the end of the thirteenth century, when human dissection was introduced into medical teaching (Pormann (ed.), 2018).
The relationship between Vesalius and the Galenic tradition illustrates the difficulty of that extraction. Vesalius’s deep knowledge of Galenic anatomy paradoxically contributed to his own disenchantment with it — his personal dissections showed where Galen had generalized from animal bodies to human ones — yet even he retained much Galenic physiological explanation in On the Fabric of the Human Body (Pormann (ed.), 2018). The arrival of “new diseases” for which there was no Galenic precedent posed an additional challenge: syphilis and other conditions revealed the limits of the ancient tradition, but this revelation could as easily promote deeper study of the ancient texts as undermine them (Pormann (ed.), 2018). By the late seventeenth century the separation of Hippocrates from Galen seemed irreversible: for many, Hippocrates had come to stand for empiricism and practice, while Galen stood for rationalism and theory (Pormann (ed.), 2018).
Van Helmont expressed this opposition sharply, claiming that Hippocrates was the first to leave a record of useful experimental practice and that Galen had taken the Hippocratic art and turned it into “idle speculation” (Pormann (ed.), 2018). Francis Bacon, for his part, saw in Hippocrates’ practice of taking a “history” of each individual patient’s illness a method that might be applied to the study of nature more generally (Pormann (ed.), 2018). Harold Cook argued that Sydenham’s Hippocrates was a Baconian collector of case studies, an inductivist who had founded the true methods of natural history and whose achievements had been devalued by rationalists like Galen (Pormann (ed.), 2018) — though Dimitri Levitin has challenged this interpretation, arguing that Sydenham was not opposed to rationalism and that for him Hippocrates was the founder of true systematic reasoning, not merely an observer (Pormann (ed.), 2018). In eighteenth-century France, Pierre-Jean-Georges Cabanis saw Hippocrates as a “philosopher-physician” (médecin-philosophe) who combined the empirical and the rational to produce the original observational method (Pormann (ed.), 2018). Littré, editing the Corpus in the nineteenth century, held that although medicine had improved on Hippocrates, both his method and modern medicine were essentially the experimental method (Pormann (ed.), 2018).
This pattern — each era constructing a Hippocrates that validates its own methodological commitments — is itself the central finding of the scholarly reception literature. The Hippocratic tradition, as Pormann and his contributors conclude, is an “invented tradition,” constantly reinvented across time and place without following a linear development; it spreads in many directions, layered with competing meanings (Pormann (ed.), 2018).
Celsus, writing in the second or third decade of the first century CE, treated Hippocrates as the authoritative point from which the discipline’s history could be narrated, and framed medicine’s early division into diet, medicaments, and surgery as a Hippocratic inheritance.(Stapley, 2024) By the second century, the Roman army carrying this tradition into Britain was itself multicultural — drawing men from Belgium, Austria, Spain, Gaul, North Africa, and Syria — making the transmission of Hippocratic and Galenic medicine into new territories a feature of Roman military expansion.(Stapley, 2024)
Vicki Pitman’s comparative study of Ayurvedic and Hippocratic texts identifies seven correspondences between doshas and humours, concluding that although the two traditions used terms drawn from different cultural systems, “the experience which generated the concepts, that of the human body-mind-spirit whole, was the same.”(Stapley, 2024) In the medieval English tradition, the Macer Floridus de Viribus Herbarum records thirty-six therapeutic uses for betony — a huge increase from what appears in Dioscorides — reflecting the plant’s adoption into Celtic and Roman traditions before the medieval period, as part of the broader expansion of the Hippocratic materia medica as it moved through cultures.(Stapley, 2024) In seventeenth-century England, Culpeper’s astrological approach to prescribing worked with both sympathetic cures (herbs of the planet governing the diseased organ) and antipathic ones (herbs of the opposing planet), reserving antipathic treatment for acute situations as potentially damaging — a distinction Culpeper traced explicitly to the Hippocratic tradition.(Stapley, 2024)
Giorgio Baglivi (1668–1707) embodied a profound contradiction: a dogmatic iatromechanist in theory but an empirical Hippocratic clinician in practice who explicitly praised observation over hypothesis (Henry E. Sigerist, 1933). Sigerist described him as “a remarkably able observer” whose practical method was free from the preconceptions his theoretical writings proclaimed (Henry E. Sigerist, 1933). [GAP: The claim that this contradiction was characteristic of the period and that claiming Hippocratic authority became compatible with any theoretical allegiance is not supported by the cited card.]
Hippocrates in Popular Culture
Pormann’s survey of Hippocrates’ reception draws a structural distinction between two kinds of engagement with his name that operate quite differently: the man as a biographical and ethical character (drawn on for aphorisms, life stories, and moral examples), and Hippocrates as a figure in professional training (the shaping authority for how medicine defines its own competence and obligations).(Pormann (ed.), 2018) These two registers often drew on the same sources but served different purposes and reached different audiences. The biographical-character strand dominates popular culture; the professional-training strand dominates medical education and institutional self-definition.
Pormann’s survey of Hippocrates’ modern afterlife reveals a shape-shifter who has taken on quite different identities depending on the medium. In the late nineteenth and twentieth centuries, writers drew on his name to organise a longing for a lost organic world where the doctor was treated with near-religious deference and the healing power of nature had not yet been displaced by modern technology (Pormann (ed.), 2018). Arthur John Brock, physician translator of Galen’s On the Natural Faculties, exemplified this tendency by reading Hippocrates’ vitalistic view of disease as the medical representative of the sanity and common sense that characterised classical Greek culture (Pormann (ed.), 2018). Brock went further, speculating that the Cnidian tendency to regard diseases as things rather than processes was itself a product of political subordination — the physicians of Cnidus living under Carian and Lydian despots, in contrast to the relative freedom of the island of Cos (Pormann (ed.), 2018).
The story of refusing the Persian king’s gold has lent itself to political appropriation across very different contexts. Pormann notes that the same Artaxerxes narrative has been read as evidence of Greek patriotism in Greek-language reception and of untrustworthiness in Roman readings that viewed a doctor who refused the command of a legitimate sovereign as deficient in professional obligation.(Pormann (ed.), 2018) The Edinburgh physician Begbie, writing in 1872, drew on the Artaxerxes story as evidence of the Greek spirit of freedom — making Hippocrates’ refusal serve a Victorian argument about liberty and national character rather than a medical one.(Pormann (ed.), 2018)
In popular media, Hippocrates has appeared as a walk-on character in the 1957 Marx Brothers film The Story of Mankind and as the prize in the 1942 film The Perils of Nyoka, where the heroine battles the villain to retrieve the lost tablets of Hippocrates — imagined as a cure for cancer (Pormann (ed.), 2018) (Pormann (ed.), 2018). On television he was brought back in 1996 by Xena: Warrior Princess, who taught him techniques of tracheotomy and CPR (Pormann (ed.), 2018), and he appears as the all-knowing medical computer in the 1998 science fiction series Mercy Point, as a cartoon character in the 1998 Disney television series Hercules (Pormann (ed.), 2018) (Pormann (ed.), 2018), and as the devoted four-armed alien companion of L. Ron Hubbard’s “Ole Doc Methuselah” (Pormann (ed.), 2018). His name has given rise to Dr Hippocrates Noah in Deep Space Nine, an episode of that series titled “The Hippocratic Oath,” and a song by Hoagy Carmichael, “The Army of Hippocrates” (1942) (Pormann (ed.), 2018) (Pormann (ed.), 2018). The physician-columnist Eugene Schoenfeld adopted the pseudonym “Dr. Hip Pocrates” in the San Francisco Bay area counterculture (Pormann (ed.), 2018). Pormann summarises the phenomenon: Hippocrates has taken on different identities over the millennia, reflecting ever-changing medical, political, religious, and cultural interests and agendas (Pormann (ed.), 2018).
The Arabic Transmission
The Hippocratic and Galenic medical traditions survived the collapse of the Western Roman Empire largely through their preservation in the Byzantine East and in the Persian and Arab Near East (Andrew Scull, 2015). Scull notes that Hunayn ibn Ishaq (d. 873) and his circle translated 129 Galenic texts into Arabic (Andrew Scull, 2015), and that these translations continued to shape medical practice in the Near East long after the texts had been lost or marginalised in Western Europe (Andrew Scull, 2015).
Pormann makes an important distinction within the Arabic reception: although Galen’s technical influence on the tradition far outstrips that of Hippocrates, Hippocrates exercised greater power over the imagination of generations of Arab and Muslim physicians, becoming something of a household name (Pormann (ed.), 2018). For beginners in medicine across both traditions, the reinterpretation of Hippocratic doctrines produced a simplified “basic Hippocrates to be learned by heart,” while his wording was filtered through Galen’s texts in a way that in practice substituted Galen for the original author (Pormann (ed.), 2018). The Arab physician-historian Ibn Abī Uṣaybiʿa (d. 1270) organised the history of Greek medicine into four periods: a mystical prehistory; the period of Hippocrates, when he “propagated the art of medicine”; the age of Galen; and the Late Antique Alexandrian tradition — thereby recognising Hippocrates and Galen as the two poles around which the entire tradition was organised (Pormann (ed.), 2018).
The mechanism of that transmission has been studied in detail. Galen’s commentaries on Hippocratic works served as the prism through which the Greek texts were read, translated, and interpreted in the Arabo-Islamic world (Pormann (ed.), 2018). The Arabic-language Hippocrates arrived bundled with Galen’s exposition, and this mediation was material: Ḥunayn ibn Isḥāq (d. ca. 873), the principal translator of medical works from Greek into Arabic, had studied at Alexandria and compared medical teaching in Baghdad to the Alexandrian tradition (Pormann (ed.), 2018). His Arabic translation of the Aphorisms was extracted directly from his translation of Galen’s Commentary on the Aphorisms — meaning the Hippocratic text embedded in Arabic manuscripts was already shaped by Galen’s understanding of it (Pormann (ed.), 2018). One concrete illustration: in translating aphorism 5.22, Ḥunayn wrote “pains” rather than “fractures” because Galen had stated in his commentary that “pains” was the better reading, and this editorial judgment flowed into the Arabic text and all descendants that drew from it (Pormann (ed.), 2018). There were at least two Arabic versions of the Aphorisms — an older paraphrastic translation attributed to al-Biṭrīq and Ḥunayn’s newer idiomatic one — with the Syriac translation also surviving (Pormann (ed.), 2018).
Ibn Riḍwān recorded that the Alexandrian curriculum taught four Hippocratic texts in its amphitheatres: Aphorisms, Prognostic, Regimen in Acute Diseases, and Airs, Waters, and Places (Pormann (ed.), 2018). This Alexandrian canon set the agenda for Arabic commentary. The Aphorisms attracted more exegetical attention in Arabic than any other Greek medical text: at least twenty commentaries are known, spanning more than a hundred manuscripts across numerous libraries (Pormann (ed.), 2018). Among the most celebrated of these commentators was Ibn Abī Ṣādiq (d. after 1068), known in the Arabic tradition as the “second Hippocrates” (Buqrāṭ al-thānī); his commentary survives in about forty manuscripts, the oldest dating to his own lifetime, the youngest produced in 1942 (Pormann (ed.), 2018). Ibn Abī Ṣādiq’s preface gives some sense of what the Aphorisms meant to Arabic physicians: he writes that each aphorism “contains a principle that could only have come from someone who obtained it with help from heaven [taʾyīd samāwī] and divine support [tawfīq ilāhī],” concluding that Hippocrates was divinely inspired and that “not one word in this excellent work is wrong” (Pormann (ed.), 2018).
The biographical legends similarly circulated in Arabic. The lovesick prince story, in which Hippocrates diagnoses a prince’s passion by holding his pulse while women from the harem were brought before him one by one, appears in al-Sijistānī’s Cabinet of Wisdom and traces back to a Greek Life of Hippocrates falsely attributed to Soranus (Pormann (ed.), 2018). The patriotism narrative — Hippocrates refusing to treat the Persian king out of loyalty to Greece — also circulated in Arabic, with versions in both al-Sijistānī and Ibn Fātik, though the Arabic versions name Artaxerxes as Bahman Ardašīr and transpose the story into Persian cultural idiom (Pormann (ed.), 2018). The Aphorisms also entered gnomological literature: anthologists extracted its sayings alongside philosophers’ proverbs, with the opening line — “Life is short, the art is long, opportunity fleeting, experience dangerous, and decision difficult” — appearing as the prime example of Hippocratic wisdom (Pormann (ed.), 2018).
The question of which Hippocrates stood behind all these texts was already troubled in Arabic. Thābit ibn Qurra (d. 901) reportedly distinguished among four different “Hippocrateses,” probably drawing on a Late Antique source such as Stephen of Alexandria, who had likewise distinguished four: the first was “the famous and well known one”; the second (Hippocrates, son of Heraclides) lived nine generations later; the third (Hippocrates, son of Draco) came another eleven generations after that; and the fourth was the third’s nephew (Pormann (ed.), 2018). Ibn Abī Uṣaybiʿa (d. 1270), organising the whole history of Greek medicine, placed Hippocrates and Galen as the poles around which the tradition was structured (Pormann (ed.), 2018). And al-Rāzī, the leading empirical clinician of the Islamic world, put the Epidemics directly to experimental use: drawing on Ḥunayn’s Questions on the Epidemics, he divided patients suffering from “brain fever” into two groups, phlebotomising one group while deliberately leaving the other untreated, then observing outcomes — one of the earliest documented uses of a control group in medical experimentation (Pormann (ed.), 2018).
Sigerist traced this transmission in his accounts of the two dominant figures of Islamic medicine. The Arab world created the political and intellectual conditions for this absorption: within roughly a century of the Hegira, an empire stretched from the Pyrenees to the Indus, encompassing populations that preserved Greek learning in Syriac, and translation into Arabic was facilitated by the earlier Syriac versions (Henry E. Sigerist, 1933) (Henry E. Sigerist, 1933). The physician Rhazes (Abu Bekr Mohammed ibn Zakkariya, Ar-Razi, c. 865–925) was born in northeastern Persia, came to medicine late after earlier study of philosophy and music, and became the leading clinician of the Islamic world (Henry E. Sigerist, 1933). His method of selecting the site for the Baghdad hospital by hanging uncooked meat at candidate locations and choosing where putrefaction was slowest expressed a Hippocratic sensibility about environmental causation of disease (Henry E. Sigerist, 1933). His treatise On Smallpox and Measles is one of the first disease monographs in medical history — containing excellent clinical description despite not sharply distinguishing the two conditions (Henry E. Sigerist, 1933). His posthumous encyclopaedia El-Hawi (the Continens of Latin translation) synthesised Greek, Arabian, and Indian knowledge enriched by his own clinical observations (Henry E. Sigerist, 1933).
Avicenna (Abu Ali Husain ibn Abdullah ibn Sina, c. 980–1037) was an infant prodigy who memorised the Quran at ten and gained fame as a physician at eighteen (Henry E. Sigerist, 1933). Sigerist characterised the contrast between Rhazes and Avicenna as that between a musician and a logical thinker, a clinician and a systematist (Henry E. Sigerist, 1933). Avicenna’s Canon of Medicine was divided into five sections covering medical theory, simple drugs, special pathology, general diseases, and the pharmacopoeia, and used Aristotelian dialectic (Henry E. Sigerist, 1933). This work dominated Western medical education from the thirteenth to the seventeenth century and continued in Eastern curricula into the twentieth (Henry E. Sigerist, 1933).
Islamic medical knowledge reached medieval Europe through two routes: Constantine of Africa’s translations at Salerno, which opened Latin readers to Arabic reworkings of the Galenic and Hippocratic tradition, and the Toledo school of translators in the late twelfth century, which recovered additional Greek and Arabic texts for European use (Henry E. Sigerist, 1933). These translations reintroduced Hippocratic texts — including the Aphorisms — to a Western readership that had largely lost direct access to them, and the medieval Hippocrates was largely the product of this Arabic-to-Latin transmission rather than any continuous Greek textual tradition.
Nutton characterizes his own book as “the first anti-Galenic history of ancient medicine,” deliberately delaying well-known texts and introducing unfamiliar figures to counter Galen’s dominance of the narrative (Nutton, 2023). His most striking conclusion about the period Hippocrates inhabited is its diversity: there was no single medical tradition even in Hippocrates’s time, and uniformity remained only a distant hope in Galen’s day (Nutton, 2023). (Hynek Bartoš and Vojtěch Linka, 2024): Bacchius of Tanagra, a disciple of Herophilus of Alexandria and a commentator and glossator of Hippocrates, attests about twenty texts attributed to Hippocrates. Three centuries later, Erotianus mentions about forty, and the 1526 Aldine edition (as well as most subsequent editions, including Littré) consist of 60 or so treatises. (Hynek Bartoš and Vojtěch Linka, 2024): Galen already distinguished between authentic and inauthentic Hippocratic texts according to his “thoroughly subjective notion of what was worthy or unworthy of Hippocrates”. He even devoted an entire treatise to the topic (On the Authentic and Illegitimate Writings of Hippocrates), which unfortunately has been lost.
