Summary
Hippocratic medicine names the medical tradition associated with the Hippocratic Corpus, a collection of roughly sixty texts composed by multiple authors between approximately 430 and 330 BCE. Hippocrates has been called the “father of medicine” and has inspired generations of physicians over millennia in both the East and West.(Pormann (ed.), 2018) He is the most famous physician from antiquity, and possibly of all time: in the five years preceding the 2018 Cambridge Companion to Hippocrates alone, some three hundred articles in medical journals discussed various aspects of Hippocrates.(Pormann (ed.), 2018) Yet the historical Hippocrates was born on Cos around 460 BCE, was of small stature, willing to teach medicine for a fee, and known to Plato and Aristotle — and how prominent he actually was, and whether any book of the Hippocratic Collection was written by him, remain open questions.(Temkin, 1991)
The tradition he gave his name to is characterized by three intellectual commitments: naturalism (disease has physical causes, not divine ones), close bedside observation, and individualized treatment through attention to the patient’s body, diet, and environment. The physician’s role was to assist nature’s own healing tendency rather than to force a cure. Therapeutic practice placed diet first, drugs second, and surgery last. What historians call “Hippocratic medicine” is partly a historical construction assembled through centuries of commentary, most influentially by Galen in the second century CE, but the tradition carried a genuine coherence around its core commitments that gave it staying power across Greek, Roman, Islamic, and medieval Latin medicine.
The Corpus and the Construction of a Tradition
What we call Hippocratic medicine was never a single, unified system. The Hippocratic Corpus is the product of a long accretive canonization process that absorbed nearly all surviving non-fragmentary medical literature from the classical period.(Hynek Bartoš and Vojtěch Linka, 2024) The texts contain mutually contradictory views on humoral theory, on the relationship between medicine and philosophy, and on the proper limits of surgery.(Ackerknecht, 1955) Modern scholarship has largely abandoned the project of identifying which, if any, texts can be attributed to the historical Hippocrates himself; as the editors of a recent volume on Aristotle and medicine conclude, “statements prefaced by ‘Hippocrates said…’ are fundamentally misplaced.”(Hynek Bartoš and Vojtěch Linka, 2024)
The collection grew steadily over time. Bacchius of Tanagra, a disciple of Herophilus working in Alexandria in the early third century BCE, attested about twenty texts as Hippocratic. Three centuries later, the grammarian Erotianus mentioned about forty. The 1526 Aldine printed edition, which became the foundation of modern scholarship, contained sixty or more.(Hynek Bartoš and Vojtěch Linka, 2024) Galen himself, writing in the second century CE, distinguished authentic from inauthentic texts by criteria he frankly acknowledged were based on his own sense of what was “worthy” of Hippocrates. He even composed a now-lost treatise called On the Authentic and Illegitimate Writings of Hippocrates to adjudicate these disputes.(Hynek Bartoš and Vojtěch Linka, 2024)
Some scholars have pressed even further, suggesting that the “Hippocratic question” — the project of identifying what is authentically Hippocratic — is essentially meaningless and that the very concept of Hippocratic medicine is flawed from the start, treating the Corpus as a “Renaissance construct” that modern scholarship should dismantle rather than interpret.(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). The traditional Coan/Cnidian division, long deployed as an organizing framework for Hippocratic scholarship, has been largely abandoned by modern scholars who regard it as an oversimplification that does not map onto the actual diversity within the texts (Pormann (ed.), 2018). The transmission of these texts is itself complicated: 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). One measure of ancient reading priorities survives in the papyrus record: the Aphorisms is attested by ten surviving papyri, more than any other Hippocratic work (Pormann (ed.), 2018).
This interpretive history matters for understanding the tradition. What we call “Hippocratic medicine” is, in William Francis Bynum’s formulation, “a historical construct, achieved by picking out certain themes and theories, and putting them together in a framework that was unknown during the centuries of the composition of the treatises.”(Bynum, William, 2008) The construct is nonetheless real in its effects. The themes selected across two millennia of commentary (naturalism, observation, the healing power of nature, individualized regimen) form a coherent enough cluster to give the tradition genuine identity.
Naturalism as the Founding Commitment
The clearest statement of what distinguished Hippocratic medicine from its competitors appears in the treatise On the Sacred Disease, which takes up epilepsy. The author opens by declaring 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. Men regard its nature and cause as divine from ignorance and wonder.”(Ackerknecht, 1955) Erwin Ackerknecht, a historian of medicine who trained in both medicine and anthropology, called this the Hippocratic “declaration of independence”: the founding assertion that disease, all disease, operates through natural mechanisms that a physician can study and learn to influence.(Ackerknecht, 1955) Significantly, the text does not use the word “soul” (psyche) in discussing mental experience; it attributes all mental processes to the brain, treating cognition, emotion, and consciousness as cerebral functions rather than as activities of a separate immaterial entity.(Jackson (ed.), 2011) The companion treatise On Regimen extends this somatic account of mental life: it attributes the character of mental states (intelligence, folly, courage, timidity) to the relative proportion of fire and water in the soul, treating psychological variation as physiological variation expressed in the language of elemental composition.(Jackson (ed.), 2011)
Jouanna’s reconstruction places this naturalism inside a specific social setting. Rational Asclepiad medicine of the kind associated with Hippocrates did not in fact emerge from the temples of Asclepius: the later tradition that Hippocrates learned medicine from healing accounts inscribed on temple steles is, on Jouanna’s reading, a legend put into circulation by the Asclepiad clergy to appropriate the great physician’s glory.(Jouanna, 1999) Hippocrates received his medical education within the family in keeping with Asclepiad tradition; at this period that teaching was essentially oral and practical, with children of the medical clans practicing dissection from childhood under parental instruction as they did reading and writing.(Jouanna, 1999) The split between this family-trained, secularizing strand of medicine and the temple-cult medicine that operated in parallel at the Asclepieia is part of what made the naturalistic stance of texts like On the Sacred Disease a recognizable position rather than a generic commonplace.
The declaration was not a rejection of religion as such; the Corpus contains prayers and acknowledges the gods. What it rejected was the explanatory use of divine agency as a substitute for physical investigation. Despite their many differences, the theoretical texts of the Corpus share a general commitment to the physical causality of disease and a corresponding rejection of any appeal to divine intervention, at least in specific cases.(Pormann (ed.), 2018) The physician’s task was to identify natural causes, not to seek divine intervention. This naturalistic stance became, through later commentary and institutional adoption, one of the defining marks of learned medicine across the Western tradition.
The Hippocratic naturalistic stance had philosophical antecedents. Alcmaeon of Croton (early fifth century BCE) had defined health as an “equality of powers” (isonomia) among opposing qualities in the body, and disease as the “monarchy” (monarkhia) of one quality — an early theoretical framework that shaped Hippocratic aetiological thinking (Pormann (ed.), 2018). Within the Corpus, the clearest naturalistic statement in pathological terms is in On the Sacred Disease: the text argues that epilepsy has a natural, brain-based cause (excess phlegm blocking the brain) and emphatically rejects divine or demonic agency, not on sceptical grounds but on the grounds that such attribution is intellectually dishonest toward the gods (Pormann (ed.), 2018). The rejection of supernatural causation also extended to epidemic disease: the Hippocratic texts attribute epidemic conditions not to contagion from person to person but to shared environmental factors — corrupted air, water, climate, and season — affecting all inhabitants of a region simultaneously (Pormann (ed.), 2018). Airs, Waters, Places is the first systematic treatise to extend this environmental reasoning comprehensively, arguing that climate, water quality, and topography determine both individual constitutions and the characteristic diseases of populations (Pormann (ed.), 2018).
The concept of physis (nature) was central to this project. The term physicus, from which the English “physician” derives, originally meant someone with specialist knowledge of nature as a whole.(French, 2003) The physician was, on this account, a student of natural processes who applied that knowledge to the particular case of the human body in health and disease.
By late antiquity, it had become a commonplace to say that “medicine is the philosophy of the body and philosophy the medicine of the soul.” The idea of two forms of medicine — one healing bodily diseases by diet, drugs, and surgery, the other healing the troubles of the mind by reasoning and psychological techniques — was popular among pagans and Christians alike and structured the cultural reception of the Hippocratic tradition throughout late antiquity.(Temkin, 1991) The introduction of correct regimen as a treatment of disease supplemented older therapeutic forms — drugs and surgery — around the beginning of the fifth century BCE, adding a new speculative dimension to medicine and inviting hypotheses about body and food constituents drawn from natural philosophy.(Temkin, 1991) This expansion of the physician’s toolkit was not merely practical; it committed medicine to a more comprehensive theory of the body and its processes than drug and surgery practice alone required. The principle of “opposites cure opposites” — the allopathic principle known in Latin as contraria contrariis curantur — dominated Hippocratic therapeutical thinking as its primary mode of action.(Pormann (ed.), 2018) Hippocratic medicine was also psychosomatic in the sense that conditions of the body were recognized to affect mental states and vice versa; the body and soul were not felt to be separated by as deep a gulf as Descartes would later envision.(Temkin, 1991) The principle that guided practice at all levels was what Temkin identifies as the backbone of medical ethics before and after philosophical notions of philanthropy made their impact: “to help or not to harm” — an avowed maxim expressive of the good craftsman’s pride and caution rather than of philosophy alone.(Temkin, 1991)
Disease as Process: The Physiological Conception
Hippocratic medicine understood disease not as a foreign entity that invades and inhabits the body but as a disturbance of the body’s own equilibrium. Eric Cassell, a clinical internist and medical philosopher, names this the “physiological conception” and contrasts it with the “ontological conception,” the view that diseases are entities, things localized in tissues, which took hold in pathological anatomy during the nineteenth century.(Cassell, 1991)
The physiological view treats disease as an imbalance, a disruption of the proper blending of the body’s constituents. The Hippocratic On Ancient Medicine states the core principle: “A human is healthy when an effective blending prevents any particular bodily constituent from manifesting itself more than necessary. Disease and pain arise from the disruption of the proper equilibrium, when one bodily constituent prevails over the others or separates itself from the blending.”(Hynek Bartoš and Vojtěch Linka, 2024)
This model made disease irreducibly individual. The same food that harms one person may strengthen another, because the damage depends on the specific interaction between the food and the particular humoral constitution of that body.(Hynek Bartoš and Vojtěch Linka, 2024) Generalizations about disease were therefore always conditional on the patient’s individual nature, season, climate, and history. For detail on the specific humoral theory that underpinned this view, see humoral-theory.
The Hippocratic author of On Ancient Medicine was a sharp opponent of the philosophical approach to medicine, which sought to reduce health and disease to a single pair of qualities (hot and cold, or wet and dry) borrowed from natural philosophy. Such reductions, the author argued, produce claims too general to explain why the same food harms some people but leaves others unaffected.(Hynek Bartoš and Vojtěch Linka, 2024) The measure for any dietary prescription cannot be found “in number or weight besides, but only in the feeling of the body.”(Hynek Bartoš and Vojtěch Linka, 2024) Medicine’s claim to be a genuine art, not mere guesswork, rested on precisely this attentiveness to individual variation.
This anti-reductionism had both a positive and negative thesis. Negatively, it rejected explanations from elementary qualities or from a prior theory of human origins.(Hynek Bartoš and Vojtěch Linka, 2024) Positively, it argued that medicine should study two domains with achieved precision: the dynameis (powers and strengths of humours in the body) and the schemata (structures of internal parts analyzed for their capacity to draw, retain, or release fluids).(Hynek Bartoš and Vojtěch Linka, 2024) Medicine derived its legitimacy from this careful attention to bodily processes, not from speculative first principles.
Epistemological Foundations
The Hippocratic Corpus contains the first known systematic self-reflection about medical method in the history of Western medicine, raising explicit questions about how knowledge of the body is acquired and what counts as evidence (Pormann (ed.), 2018). Lorenzo Perilli, surveying these epistemological texts, identifies the Prognostic as central: it argues that the physician’s ability to predict the course of disease is the surest mark of medical skill and the best way to establish authority with patients (Pormann (ed.), 2018). This dual ideal runs through the whole tradition: the physician must possess both episteme (systematic knowledge) and metis (practical wisdom, the situational judgment to adapt general principles to each individual case) (Pormann (ed.), 2018).
Nosology: Disease Classification
The term “nosology” (systematic classification of diseases) is a modern word not used by ancient physicians; the Corpus does not present a unified disease taxonomy but addresses individual diseases in a variety of overlapping frameworks (Pormann (ed.), 2018). The core nosological treatises are Diseases 1–4, Regimen in Acute Diseases, and Affections; they present disease in structured units combining a disease label, characteristic symptoms, humoral aetiology, recommended treatment, and prognosis for recovery or death (Pormann (ed.), 2018). This nosographic unit — label, symptoms, aetiology, treatment, prognosis — is the key literary-medical form of Hippocratic disease description (Pormann (ed.), 2018). A methodological tension within the Corpus appears in Regimen in Acute Diseases, which criticized the lost “Cnidian Sentences” for proliferating too many disease categories and distinctions, implying that the Coan tradition preferred fewer, broader classifications adequate to guide treatment (Pormann (ed.), 2018). Underlying the different written treatises, Amneris Roselli argues, is a shared stock of traditional knowledge about specific diseases — fevers, pneumonia, pleurisy — that suggests a professional oral tradition on which all the texts drew (Pormann (ed.), 2018).
The Therapeutic Hierarchy: Regimen, Drugs, Surgery
If disease was disturbance of natural balance, the physician’s primary tool was whatever could restore that balance by working with the body’s own tendencies rather than against them. The Hippocratic tradition assigned a clear hierarchy to therapeutic interventions. Diet (in the ancient sense of diaita, encompassing food, drink, exercise, sleep, and sexual activity) came first. Only if diet failed were drugs employed. Surgery was a last resort.(Ackerknecht, 1955)
This hierarchy reflects the tradition’s underlying conviction about nature’s own healing power. The physician was an assistant to a process already underway; the body, given appropriate conditions, tended toward recovery. For the full treatment of this doctrine, see vis-medicatrix-naturae.
The emphasis on diet connected Hippocratic medicine to a broader tradition of dietary medicine that traced the art’s origins to the history of cooking. The author of On Ancient Medicine argued that cooking and medicine shared a methodological structure: both discover appropriate processes to neutralize the power of harmful substances, and both aim at the proper functioning of specific body types.(Hynek Bartoš and Vojtěch Linka, 2024) This genealogy grounded medicine’s claim to practical authority in a craft tradition rather than in abstract philosophy.
Laurence Totelin’s analysis of Hippocratic drug lore shows that drugs were classified not by botanical family but by their point of entry and mode of action: purgation upward (vomiting), downward (evacuation), through sweating, or through urine — a therapeutic logic focused on expelling harmful humours by the most efficient route (Pormann (ed.), 2018). This classification instantiates the allopathic principle: “opposites cure opposites” (enantia tois enantiois iatreiai), so that diseases characterised by cold were treated by heat, those by dryness by moistening treatments (Pormann (ed.), 2018). Hippocratic therapeutics was genuinely innovative relative to earlier Greek medicine: the Corpus introduced systematic drug prescriptions, dietary regimens, and surgical procedures that represent a substantial body of practical medical knowledge (Pormann (ed.), 2018). Totelin emphasises that the boundary between folk or popular remedies and learned Hippocratic medicine was permeable: many drugs and treatments in the Corpus derive from traditional popular knowledge, indicating that learned medicine drew on and interacted with lay medical culture rather than standing apart from it (Pormann (ed.), 2018). The most extensive Hippocratic therapeutics text, Regimen (Diaita), presents a comprehensive system of health maintenance through diet and exercise calibrated to individual constitution, season, climate, and occupation (Pormann (ed.), 2018).
Hippocratic surgery merits brief notice here. The notion of surgery (cheirourgía) in antiquity covered all manipulations with hands and instruments on a patient, not merely cutting: much of orthopaedics, for instance, involved no incision (Pormann (ed.), 2018). The Corpus lacks systematic treatises on non-trauma surgery, but its accounts of fracture and dislocation management are detailed and technically sophisticated. All ancient surgical operations were performed without anaesthesia; narcotics such as mandrake and opium were known but not administered prior to operations because the difficulty of achieving safe dosage made the risk of killing the patient too high (Pormann (ed.), 2018).
In practice, the Hippocratic physician attending an acute illness would observe the patient closely, noting the skin, eyes, breath, and posture. The Prognostics described this cluster of signs as the “Hippocratic facies,” which could indicate whether death was near.(Ackerknecht, 1955) The Epidemics, case records describing individual patients through the course of their illnesses, exemplified this observational ethos. The author of Epidemics I reported forty-two cases, of which twenty-five died. Ackerknecht marked this unusual willingness to report failures as “a rare example of scientific honesty” in ancient medicine.(Ackerknecht, 1955)
Prognosis and the Social Position of the Physician
Hippocratic emphasis on prognosis, predicting the course of disease before it unfolded, had a social as well as a clinical rationale. The Greek physician of the classical period was typically an itinerant craftsman without fixed institutional position, dependent on reputation to attract patients.(Ackerknecht, 1955) In the absence of academic degrees and licenses, laymen’s suspicion of physicians was understandable; distinguishing the good doctor from the charlatan required observation of ethics and behavior as well as of clinical outcomes.(Temkin, 1991) A physician who could correctly predict the patient’s fate gained trust rapidly; one who accepted a hopeless case and failed would lose it. Prognosis thus served the physician’s reputation alongside the patient’s welfare.(French, 2003)
The Hippocratic text Precepts addressed the question of fees directly, advising physicians not to begin by discussing payment with suffering patients and to consider patients’ economic condition: sometimes treating gratis, sometimes helping destitute aliens above all, combining economic realism with philanthropy.(Temkin, 1991) The same text identified philanthropy (philanthropia) as the key ethical principle: “if love of men is present, love of the art is also present,” making love of patients and dedication to the craft inseparable.(Temkin, 1991) The deeper question of medicine as a liberal art — whether accepting fees degraded the physician to a hired workman — was addressed in the Pseudepigrapha, where Hippocrates insisted that medicine must remain free and independent, capable of being practiced by a free man rather than one subject to the commands of an employer.(Temkin, 1991) The question of medical fees thus carried a social and ethical charge that extended well beyond simple economics.
The treatise Prognosis opens with this strategic logic close to the surface: the physician who practices careful prediction “will be trusted by the public” and will avoid the association with death that came from taking on cases already beyond recovery. For a detailed account of the doctrine, see prognosis.
The Hippocratic physician was expected to read the patient’s entire situation, not only the presenting complaint. Bynum notes that this required knowing “what his social, economic, and familial circumstances were, how he lived, what he usually ate and drank, whether he had travelled or not.”(Bynum, William, 2008) The absence of hospitals meant that care took place at the patient’s own bedside; the physician arrived, observed, prescribed, and departed. This structure gave Hippocratic medicine a profile that Bynum calls the prototype of modern primary care, attentive to the whole person in their social and environmental context.
The link between observation, prognosis, and crisis is discussed in crisis-doctrine.
The Epidemics books are the primary source for understanding the Hippocratic doctor-patient relationship, containing hundreds of case histories that record the physician’s observations of individual patients across the course of illness (Pormann (ed.), 2018). Chiara Thumiger’s analysis of this material identifies two social features of Hippocratic practice that bear on these records. First, Hippocratic physicians were largely itinerant practitioners who travelled between communities, treating patients during temporary stays; they did not typically maintain ongoing relationships with a fixed local patient population (Pormann (ed.), 2018). Second, prognosis served primarily to protect the physician’s reputation: by declaring in advance what will happen to a patient, the physician demonstrates skill if correct and limits reputational damage if the patient dies (Pormann (ed.), 2018). The patient’s voice in the Epidemics is filtered almost entirely through the physician’s account; patient statements appear mainly in indirect speech and are selected for their diagnostic relevance, not as expressions of the patient’s subjective experience (Pormann (ed.), 2018). Yet these indirect speech passages do preserve traces of the patient’s own perspective, showing that patients communicated their symptoms and experiences to physicians and that this information entered the clinical record (Pormann (ed.), 2018). Some Hippocratic texts take a more collaborative stance: Regimen and Affections address an educated lay audience of “intelligent men” who can understand and participate in their own health management, suggesting a more collaborative model than the Epidemics case records convey (Pormann (ed.), 2018).
Aetiology and Causal Reasoning
Hippocratic aetiological thinking operated through a distinction that modern readers can easily miss. The term próphasis, often translated as “cause,” more precisely means an evident antecedent circumstance, something observable that attends the onset of disease. As the chapter on Hippocratic causation in the Cambridge Companion to the Corpus explains, “a próphasis is something which is obvious. In medicine, propháseis are often contrasted, as the evident antecedent circumstances attending the diseases, with the causes.”(Pormann (ed.), 2018) The Hippocratic physician was therefore making a two-level distinction: the manifest trigger (eating something unusual, a sudden change in weather) and the deeper constitutional or humoral condition that made the patient susceptible to that trigger. Confusing the two was a characteristic error documented in Ancient Medicine 21, where the author observes that “most doctors, like lay-people, assign responsibility to one of them, and in ignorance of the real cause” — blaming, for instance, a single unusual food eaten on the day of crisis rather than the patient’s underlying imbalance.(Pormann (ed.), 2018)
The author of Ancient Medicine pressed this point against colleagues who had adopted the philosophical vocabulary of the four primary qualities. The first serious investigators, he argued, “did not consider the dry, the wet, the hot or the cold…to harm or to be of any benefit to man, but rather they thought that the strength of each thing” (meaning the specific powers and intensities of actual foods and medicines) was the relevant causal factor.(Pormann (ed.), 2018) Heat and cold were at most concomitant conditions, not primary causes. This position placed the Hippocratic craft tradition in explicit opposition to those physicians who had borrowed reductive explanatory schemes from the natural philosophers.
Epidemic disease presented a related but distinct problem. Breaths 6 identified the air as the common medium of epidemic fever, noting that different animals are affected differently because of body and nature differences, in what amounts to a proto-ecological account of host susceptibility within a shared environment: “There are two kinds of fevers, one common to all…called ‘plague’…air is the cause of both.”(Pormann (ed.), 2018) Crucially, this atmospheric framework displaced any notion of disease transmission from person to person. Hankinson’s analysis in the Cambridge Companion identifies “the complete absence of any idea that disease is something that can be transmitted from one individual to another” in the Hippocratic texts, attributing this lacuna to the fact that such an idea “was associated with an earlier, supernatural paradigm” and was therefore not available to physicians committed to naturalistic explanation.(Pormann (ed.), 2018)
Beneath these competing theoretical frameworks, the tradition held a set of shared methodological commitments. R. J. Hankinson identifies a common ground that persisted across the internal debates: “a commitment to generality of explanation” across multiple cases, and the corollary that “appeals to divine intervention…are correspondingly rejected” as explanatory moves.(Pormann (ed.), 2018) Individual variation was accounted for not by divine whim but by constitutional differences in the patient’s body, the interaction of constitution with season and diet, and the particular history of the illness.
The method for building generalizations from cases is described with unusual explicitness in Epidemics 6.3.12, which characterizes the physician’s inductive work as assembling a “complete summary account” that “derives from the genesis and the points of origin, and from many accounts,” learning gradually, comparing likenesses and dissimilarities across multiple patients, and arriving at a unified type.(Pormann (ed.), 2018) This is as close as any ancient medical text comes to articulating an explicit methodology of clinical induction.
Epistemology and Method
The Cambridge Companion’s chapter on Hippocratic epistemology, assembled by Lorenzo Perilli, identifies what he calls an “epistemological decalogue” underlying the tradition’s self-understanding of medical knowledge: reliance on observation and empirical evidence; meticulous recording of signs, symptoms, and proofs; systematization from particular instances; generalization across cases; demarcation from supernatural explanation; awareness of the possibility of error; capacity for argumentative engagement with critics; and causal explanation as the goal of inquiry.(Pormann (ed.), 2018) These are not always articulated together in any single text; Perilli reconstructs them by reading across the Corpus. But taken together they constitute the epistemological grammar of Hippocratic medicine.
Two epistemological poles organize this grammar. At one end stands the foundational role of observation. At the other stands the necessity of reasoning when observation reaches its limit. The Art 11 states the complementary principle with directness: “what the physician cannot see with the eyes nor hear with the ears, he grasps through logismós” — reasoning — “with the ‘eye of the mind’ (Breaths 3.10).”(Pormann (ed.), 2018) Ancient Medicine 2 frames this as a settled possession: “Medicine has long since had everything it needs, both a principle (archē) and a discovered method (hodós)…Anyone who casts off…all these things, tries to investigate in another way…has been deceived.”(Pormann (ed.), 2018) The claim is polemical, directed against physicians who would import philosophical first principles, but it encodes a genuine epistemological position: that the medical craft already has its own adequate starting points and methods, neither borrowed from nor reducible to natural philosophy.
The practical articulation of this epistemology runs through The Art 6: “Medicine consists in the because of (dià tí) and in the forecasting, for everything that occurs will be found to do so through something.”(Pormann (ed.), 2018) Causal explanation (dià tí) and prospective judgment are not separate activities; they are two aspects of the same cognitive act. The physician who can say why something is happening can thereby say what will happen next.
Prognosis, on this account, is not merely predictive guesswork but the natural expression of causal understanding. Prognostic 1 makes the aspiration explicit: “It is the task of the best physician to practise forecasting” — and forecasting means to “recognise immediately and to declare publicly what has happened beforehand, the present situation and what one expects to happen.”(Pormann (ed.), 2018) The triad of past, present, and future that the Hippocratic physician was expected to traverse was not sequential in a simple sense; reading the present sign correctly already implied a causal story extending backward and forward.
The epistemological value of failure is also acknowledged. Joints 47 describes a failed attempt to reduce a dislocation using a wineskin as a lever, and the author comments: “I relate this on purpose: for those things also give good instruction which after trial show themselves failures.”(Pormann (ed.), 2018) This willingness to record and analyze therapeutic failures as data is characteristic of the same empirical ethos that Ackerknecht noted in the Epidemics: the physician who acknowledges failure honestly teaches more than one who conceals it.
Clinical Practice: The Itinerant Physician
Reconstructing the social practice of Hippocratic medicine from the case records in the Epidemics requires care, because the texts that survive are neither uniform nor unmediated. Jacques Jouanna and Chiara Thumiger both emphasize that the Epidemics books differ substantially in character: the original nucleus of the Corpus (Epidemics 1 and 3) presents “carefully crafted narratives,” while later books offer looser notes of a more variable character.(Pormann (ed.), 2018) Patient cases range from precisely observed narrative records to quick mentions, and the “wide gap between Epi 1/3 diary-reports and looser notes of Epi 2/4/6” means that any single description of Hippocratic practice overgeneralizes.(Pormann (ed.), 2018)
One feature of the practice is clear from the title itself. The term “Epidemics” derives from the Greek epidēmiai (literally “visits to the city” or “visits to the people”) and reflects the social fact that the Hippocratic doctor was itinerant, traveling between communities rather than residing permanently in any one of them.(Pormann (ed.), 2018) Individual visits lasted weeks to months; some patients appear in the records as seen only once, while others are followed across many years.(Pormann (ed.), 2018) The resulting picture is of a craft practiced in motion, building experience across multiple clinical environments rather than deepening roots in a single community.
Despite this mobility, the case records suggest a quality of attention that implies genuine familiarity. The precise personal details recorded (the patient’s name, occupation, household, neighborhood) indicate that the physician gathered intimate knowledge of the individual’s circumstances, even in the absence of an ongoing relationship.(Pormann (ed.), 2018) This is consistent with the history-taking method reconstructed by Thumiger: the physician gathered information through conversation, and “the patient’s voice is preserved though functional to physician’s agenda.” Dialogue about past illnesses and life habits was “fundamental for therapy,” not merely background color.(Pormann (ed.), 2018)
History-taking was not always direct. For gynaecological complaints, female patients required female intermediaries who served as go-betweens, channeling the physician’s questions and the patient’s answers through a social structure that maintained propriety.(Pormann (ed.), 2018) The physician’s access to the patient’s body and history was therefore socially mediated in ways that varied by gender, status, and the nature of the complaint.
The Patient’s Voice
The patient’s perspective in Hippocratic medicine is accessible only indirectly, filtered through the physician’s clinical record. Thumiger’s analysis identifies several channels through which patient experience enters the Epidemics: reported words in indirect speech, descriptions of sensorial experience (pain, discomfort, unusual sensations), and occasional emotional responses.(Pormann (ed.), 2018) These passages are not windows onto unmediated patient subjectivity; they have been selected and reframed by a physician whose primary concern was diagnostic relevance. Yet they demonstrate that communication between physician and patient was real and that what patients said was treated as clinically significant data.(Pormann (ed.), 2018)
Prognosis, as noted in the earlier discussion, served the physician’s reputation as well as the patient’s welfare.(Pormann (ed.), 2018) This social function had implications for the doctor-patient relationship: a physician who declared a prognosis publicly was staking reputation on a prediction, which created an incentive to communicate clearly, to assess honestly, and to avoid taking on cases already beyond recovery. Noncompliance was a known problem. Some Hippocratic texts show awareness that patients did not always follow instructions and that physicians sometimes employed deception or placebo effects to secure compliance.(Pormann (ed.), 2018) The physician who appeared calm and detached at the bedside was not necessarily indifferent: Thumiger’s analysis shows that beneath the surface of clinical detachment, “physicians relied on communication with patients” in ways that their formal case records underrepresent.(Pormann (ed.), 2018)
Therapeutics: Dietetics over Pharmacology
The Hippocratic Corpus contains no pharmacological treatises as such. Drug recipes appear, but they are concentrated in the gynaecological texts; references elsewhere point toward a lost work called Pharmakîtis that has not survived.(Pormann (ed.), 2018) This absence was not accidental. Totelin’s analysis in the Cambridge Companion shows that the tradition “deliberately subsumed pharmacology under dietetics,” treating drugs as an extension of dietary reasoning rather than as an independent domain.(Pormann (ed.), 2018) The practical hierarchy (diet first, drugs second, surgery last) was reinforced at the theoretical level by a conceptual absorption: drugs were a specialized form of dietary intervention, classified by their effects on the body’s humoral balance rather than by their botanical origins.
The reason for this subsumption was partly competitive and partly intellectual. Vivian Nutton’s phrase “medical marketplace” captures the social environment of Hippocratic practice: physicians competed for patients in an open market, and Regimen in Acute Diseases explicitly criticizes disagreeing physicians, evidence that the competition was visible and consequential.(Pormann (ed.), 2018) In this environment, the history of pharmacological knowledge stretched back, in the tradition’s own understanding, all the way to Apollo and Chiron. No practicing physician could plausibly claim superiority over a tradition of divine and heroic origin.(Pormann (ed.), 2018) By subsuming pharmacology under dietetics, Hippocratic physicians could claim a systematic rationale (the humoral framework and the logic of opposites) that neither folk healers nor mythological authorities possessed.
The relationship between lay and learned pharmaceutical knowledge was permeable in practice. The Affections states that laypeople discover medications by chance, but that reasoned knowledge of how and why they work must be learned from experts.(Pormann (ed.), 2018) This formulation simultaneously acknowledged popular pharmaceutical knowledge and claimed a different kind of authority for physician’s knowledge: not priority of discovery but depth of understanding.
The Hippocratic physician found many diseases caused by disregard for a reasonable way of life or by lack of self-control; such diseases could be tagged with a moral blemish, as Galen did with gout, severe arthritis, and bladder stone. To insist on a rational, wholesome way of life was a task both of the philosopher and of the physician. Yet it was not, Temkin notes, the doctor’s duty to moralize about patients’ dietary trespasses — the moral dimension of disease awareness did not convert the physician into a preacher.(Temkin, 1991)
Cos and Cnidus: The Internal Division
The Hippocratic Corpus was not the product of a single school. While most texts reflect what later tradition identified as the position of the school of Cos (Hippocrates’ home island), some treatises reflect the teachings of Cnidus and of Sicilian medicine.(Ackerknecht, 1955) The Coan and Cnidian approaches are often contrasted, though the contrast can be overstated. The conventional account holds that Cnidian medicine favored more detailed disease classification into specific named conditions, while Coan medicine concentrated on prognosis and the overall course of the illness without isolating named diseases as discrete entities.
The author of On Regimen in Acute Diseases, usually assigned to the Coan tradition, criticizes Cnidian physicians for enumerating diseases too finely while neglecting the variations in presentation that only experience could teach. The critique is methodological rather than personal: classification without observation mistakes the map for the territory.
This internal division prefigures a tension that recurred throughout the history of Western medicine: between the physician who treats diseases as named entities with fixed properties (the ontological view) and the physician who treats patients as individuals whose illness must be understood in its full particularity (the physiological view).(Cassell, 1991) Thomas Sydenham, the seventeenth-century English physician, was called the “English Hippocrates” by Giorgio Baglivi precisely because he revived the emphasis on direct observation over received theory.(Coulter, 1975) Yet Sydenham’s own work contained the seeds of modern nosology, the classification of diseases into fixed types, making him an ironic figure. Bynum notes that his thinking “had posed the modern medical dilemma: how to retain a belief in the unique individuality of each patient, and still apply the more general findings of a scientifically grounded diagnosis and therapy.”(Bynum, William, 2008)
The Physician’s Relationship to Nature
The intellectual center of Hippocratic medicine, connecting its naturalism, its therapeutic hierarchy, and its observational method, is a specific understanding of the physician’s relationship to nature. Nature (physis) has its own medicinal action. Disease, on this reading, “is a generalized reaction designed to bring about a cure; the organism develops a disease in order to get well.”(Canguilhem, 1966) The physician’s role is not to override this tendency but to assist it, to provide conditions under which the body’s own recovery can proceed.
Georges Canguilhem, the French philosopher of biology who wrote the most rigorous twentieth-century analysis of the concept of the normal, located in this Hippocratic principle a still-productive insight: that disease is not merely a deficiency of normal function but is itself a norm of life, however inferior and constrained.(Canguilhem, 1966) The organism is not passive under disease; it is actively, if imperfectly, responding to disruption.
This understanding shaped the Hippocratic aphorism that Bynum identifies as the most durable of the tradition’s legacies: “help, or at least do no harm.”(Bynum, William, 2008)(Pormann (ed.), 2018) The maxim encodes a specific theory: that the physician who does too much may interfere with the body’s own remedial effort. Aggressive intervention was not merely technically risky; it could be medically wrong.
A famous passage in the Epidemics stated the limits of this collaboration with nature without mentioning any divinity at all: “Three things make the art: the illness, the patient, and the physician. The physician is a servant of the art; the patient must oppose the illness together with the physician.” Temkin observes that this formula is as remarkable for what it omits as for what it says — no god appears as a factor in the art of healing.(Temkin, 1991) The tradition did acknowledge a divine dimension, but at the edge of its horizon. A Hippocratic author stated that “prayer indeed is good, but while calling on the gods a man should himself lend a hand,” capturing the complementary rather than competitive relationship that prevailed in pagan culture between secular medicine and divine healing.(Temkin, 1991) The Epidemics’ dictum on the healing power of nature — that constitutions are themselves the physicians of diseases, and that nature finds its own ways without instruction — expressed admiration for nature common to many Hippocratic authors, but this admiration was not essential to the science itself and could be replaced; the fundamental claim was methodological, not theological.(Temkin, 1991)
The On Ancient Medicine offered a distinctly non-divine account of medicine’s origins: human ingenuity driven by necessity, not divine gift. The sufferings inflicted by eating raw food led step by step, by trial and error, to cooking, then to special diets for the sick, then to medicine itself. “Necessity itself has made human beings seek and find medicine.”(Temkin, 1991)
The concept of physis as provident and purposive also shaped the tradition’s understanding of anatomy. The Hippocratic author of On Ancient Medicine argued that the function of internal structures could be inferred from their shapes, by analogy with external parts and tools.(Hynek Bartoš and Vojtěch Linka, 2024) You could learn what the stomach was for by attending to its structure, as you could learn what a vessel was for by attending to its form. This functional reasoning was taken up, extended, and systematized by Aristotle, who turned the question of function into the cornerstone of his natural philosophy.
Hippocratic Medicine and Aristotle
Aristotle’s relationship to Hippocratic medicine was closer than a simple division between medicine and philosophy would suggest. His father Nicomachus was court physician to the Macedonian king Amyntas III, giving Aristotle a medical upbringing before he entered Plato’s Academy.(Hynek Bartoš and Vojtěch Linka, 2024) In On Sensation, Aristotle observed that most students of natural philosophy “end by dealing with medicine, while those of the doctors who practise their art in a more philosophical manner take their medical principles from the study of nature.”(Hynek Bartoš and Vojtěch Linka, 2024) He placed medicine and natural philosophy in a reciprocal relationship rather than a hierarchy.
Aristotle cited Hippocrates by name only twice in surviving works, but he engaged extensively with medical concepts, sometimes naming specific medical figures and sometimes absorbing medical ideas without attribution.(Hynek Bartoš and Vojtěch Linka, 2024) The texts most likely known to Aristotle include On the Nature of Man, the Aphorisms, Epidemics 2, 5, and 7, On Regimen, Airs Waters Places, and On Generation.(Hynek Bartoš and Vojtěch Linka, 2024)
The methodological parallels between On Ancient Medicine and Aristotle’s Parts of Animals are genuine and striking. Both texts oppose reductionism (the attempt to explain bodily parts and processes by reference to elementary material constituents alone) and both insist on the priority of function over origin.(Hynek Bartoš and Vojtěch Linka, 2024) Both treat the investigation of bodily structure as inseparable from the question of what that structure is for. Whether Aristotle drew directly on specific Hippocratic texts or encountered the same ideas through shared medical culture remains debated; scholarly opinion ranges from strong source influence to the view that most parallels reflect common educated knowledge of the period.(Hynek Bartoš and Vojtěch Linka, 2024)
Galen, in the second century CE, called Aristotle “an interpreter of Hippocrates’ reasoning on nature,” reflecting his conviction that both drew from a shared source.(Hynek Bartoš and Vojtěch Linka, 2024) This was partly accurate and partly self-serving: Galen wanted to recruit both figures as co-witnesses to his own synthesis.
The Sectarian Debate and Hippocrates as Authority
By the beginning of the first century CE, two main sects had formed among Hippocratic followers. The Dogmatists, or Logicians, saw Hippocrates as the founder of a scientific medicine based on natural philosophy, anatomy, and physiology — in short, on hidden causes. The Empiricists, their opponents, held that nature could not be fathomed, and so speculation about hidden causes (including elements, humors, and pneuma) was useless; for them, Hippocrates was a great clinical teacher whose authority rested on experience rather than theory.(Temkin, 1991) The Methodists, a third sect arising in first-century CE Rome, stood apart: they believed medicine needed no science and rested on direct diagnosis by symptoms — constriction, relaxation, or mixture — and did not claim Hippocrates as their authority at all.(French, 2003)(Temkin, 1991)
Smith’s historical argument pushes the origin of Hippocratic doctrinal authority later than is commonly assumed: the views and importance of Hippocrates first became a subject of doctrinal dispute precisely out of the Empiric reaction against dogmatic medicine (roughly 250-100 BCE), and the Empirics gave authority to the Corpus by constructing a Hippocrates in their own image — an observer-physician opposed to theoretical speculation (Wesley D. Smith, 1979)(Wesley D. Smith, 1979). The tradition of studying Hippocratic texts runs slightly earlier to Bacchius, but Bacchius attributed no doctrine to Hippocrates; it was the Empirics who first made Hippocrates a doctrinal authority, and any earlier Hippocratism is a retrospective construction (Wesley D. Smith, 1979).
This sectarian conflict was one of the main contexts in which the Hippocratic Corpus first became a doctrinal authority. Galen’s historical contribution was to reject the sects in favor of a single medical science guided by reason and experience together; the Later Empire accepted Galen, Hippocrates, and Hippocratic medicine as seen through Galen’s eyes as the authorities representing true medicine.(Temkin, 1991) After Galen, a standard version of Hippocratic doctrine became widespread, combining the theory of the four humors, the concepts of krasis (blend of humors) and dyskrasia (morbid imbalance in the blend), the theory of temperaments, the allopathic principle (contraria contrariis curantur), and the need to adapt treatment to the patient, the season, and the environment.(Pormann (ed.), 2018) This standard version was shared by physicians across the Greek and Latin worlds, including Philagrius, Alexander of Tralles, Cassius Felix, and Theodore Priscian.(Pormann (ed.), 2018)
Galen’s formulation defined Hippocratic medicine as the great patristic authors were to see it: its main points were the basic roles of the four humors and an allopathic principle of therapy.(Temkin, 1991) His commentaries shaped not only what texts were considered central but also how they were read across Byzantine, Islamic, and Latin scholarly networks.
Galen’s Reconstruction and Its Consequences
The most consequential act in the history of Hippocratic medicine was not any text in the Corpus itself but Galen of Pergamon’s systematic reconstruction of Hippocrates as the founding authority for Galen’s own medical system. Writing in Rome in the second century CE, Galen produced extensive commentaries on Hippocratic texts, distinguishing authentic from inauthentic works, interpreting ambiguous passages in light of his own views, and in general, as Roger French observed, “reconstructing Hippocrates in his own image.”(French, 2003)
Galen’s Hippocrates was a Rationalist who endorsed humoral theory derived from the four elements, who performed anatomical reasoning, and who endorsed the authority of natural philosophy over mere empirical practice.(French, 2003) None of these claims was uncontested. The Empiricist sect, which arose in Alexandria roughly between 225 and 50 BCE, had also claimed Hippocrates as their founding authority, emphasizing the observational, case-recording aspects of the Corpus rather than its philosophical dimension.(French, 2003) Galen’s interpretation won out, largely because Galen also produced the fullest synthesis of ancient medical knowledge that survived and was transmitted forward.
For Galen, the physician who practiced the art in a manner worthy of Hippocrates necessarily possessed all three parts of philosophy: logic, natural philosophy, and ethics. Being a philosopher in Galen’s sense did not mean the contemplative life; it meant virtue lived — ethics as practice, not speculation.(Temkin, 1991) Galen did not view medicine and philosophy as two fundamentally independent disciplines; being a philosopher was not a matter of finding fulfillment in contemplation but of practicing virtue in daily life.(Temkin, 1991) He compared Hippocrates’ words to “a voice from a god,” a tribute that exceeded what a scientist typically paid to a predecessor, and that Temkin explains in part by the predisposing force of the legendary tradition that surrounded Hippocrates by the time Galen wrote.(Temkin, 1991)(Temkin, 1991) Galen’s idealization of Hippocrates drew on that legendary tradition as well as the works themselves: he recounted Hippocrates’ contempt for money, his refusal of Artaxerxes and Perdiccas, and his delegation of care to Polybus, drawing on biographical legends that he treated as historically reliable sources.(Temkin, 1991) Galen’s Hippocrates declared that the physician who is a philosopher is “godlike,” but this was not an endorsement of any and all philosophizing; only a pragmatic philosophy, lived in the right kind of person, would do.(Temkin, 1991)
Galen’s commentaries on Hippocratic texts were extensive. He distinguished between private commentaries written as personal exercises and public commentaries intended for learned readers; the public ones densely cited Hellenistic scholars who had disputed textual readings across the preceding four centuries.(Gill_ed, 2010) Through this massive interpretive apparatus, Galen positioned himself as the supreme inheritor and authentic interpreter of the Hippocratic tradition, a status that was then transmitted with his works through Byzantine, Islamic, and Latin scholarly networks.(Gill_ed, 2010)
One critical modern judgment on this project comes from the Galen scholarship of the last several decades: Galen’s recruitment of Hippocrates in support of a provident, purposive nature was, in Rebecca Flemming’s careful phrase, “basically fraudulent.” The Hippocratic Corpus texts, including those Galen most admired, are largely indifferent to the notion of a providentially designed natural order.(Gill_ed, 2010) What Galen attributed to Hippocrates was mostly Galen’s own philosophical theology.
Transmission: Hellenistic, Roman, Islamic, and Medieval Latin
The transmission of Hippocratic medicine operated through several distinct phases, each transforming what was transmitted. In Alexandria from the third century BCE onward, the collection of texts under Hippocrates’ name gave medicine the status of literature: the first commentaries on Hippocratic texts were written there, and physicians debated Hippocratic terminology alongside Homeric usage with scholars and librarians.(French, 2003) The Alexandrian library made Hippocratic medicine into a canonical textual tradition.
In Rome, Hippocratic medicine was initially unfamiliar. When Galen began to practice prognosis in the Roman manner of the Hippocratic tradition, his Roman colleagues were confused: one compared his predictions to divination from bird flight.(French, 2003) Galen’s eventual dominance reshaped what Hippocratic medicine meant in the Latin West.
In late antiquity, Stephanus the Philosopher, delivering lectures at Alexandria, defined medical craftsmen as “armed with the Hippocratic methods against diseases,” sharply distinguishing the Hippocratic physician from what he called “a doctor who happens to be an amateur.”(Temkin, 1991) This insistence on a clear boundary between the trained Hippocratic practitioner and the incompetent doctor was one of the tradition’s persistent self-assertions.
The Islamic phase is captured in Bynum’s observation that medieval Islamic medicine “was more than an interlude”: it was a vigorous learned culture that reformulated Greek medical ideas, added new observations and medicaments, and produced encyclopaedic syntheses that were then transmitted back to the Latin West.(Bynum, William, 2008) The most studied vehicle of this transmission was Avicenna’s Canon of Medicine (1025 CE), which packaged Hippocratic and Galenic wisdom in logical order and became the standard textbook in European universities, in Latin translation, for several centuries.(Bynum, William, 2008)
Ibn Ridwan, the eleventh-century Egyptian physician, applied Hippocratic environmental medicine (the tradition of Airs, Waters, Places) to a description of Egypt’s medical geography, arguing that the physician’s primary task was preventive: preserving health through regimen and prophylaxis rather than remedying illness after the fact. He cited Ludwig Edelstein’s observation that Hellenistic medicine “is concerned with the dietetics of the healthy” and that preventing illness “is considered to be not only as important as therapeutics; it seems to be even more important than healing the sick.”(Dols, Michael W. (trans.), 1984)
In medieval Latin universities, Hippocratic texts (particularly the Aphorisms and Prognostics) formed part of the articella, the basic medical curriculum. The aphorisms circulated as a repository of clinical wisdom applicable without extensive theoretical apparatus.(French, 2003) Surgeons and apothecaries trained by apprenticeship in what Bynum calls “the Hippocratic way,” while learned physicians who could dispute the niceties of Galen and Avicenna acquired a higher social status precisely because their training was literary and theoretical rather than practical.(Bynum, William, 2008)
The Hippocratic Oath deserves separate mention here: its canonical status in medical ethics is inseparable from the transmission history. Ackerknecht, following Ludwig Edelstein, notes that the Oath is most likely post-Hippocratic in origin and may reflect Neo-Pythagorean rather than mainstream Hippocratic thought.(Ackerknecht, 1955) The Christian versions of the Oath replaced pagan invocations with Christian formula; its adoption was gradual and its use among ancient practitioners was not universal.(Ferngren, Gary B., 2009) For full treatment, see hippocratic-oath.
Environmental Medicine and the Airs, Waters, Places Tradition
One of the tradition’s most consequential contributions was a framework for understanding how environment shapes health at both individual and population levels. The treatise Airs, Waters, Places is, in Bynum’s description, “the foundation statement of Western environmentalism, especially as it relates to health and disease,” offering analysis of how soil, water, climate, and the orientation of a settlement toward prevailing winds shaped the health of its inhabitants.(Bynum, William, 2008)
The Epidemics extended this analysis to season-by-season case records, tracking how the “constitution” of each year (its pattern of seasonal temperatures and winds) shaped the diseases that appeared. The physician who arrived in an unfamiliar city was advised by Airs, Waters, Places to observe its orientation, its water sources, and its residents’ habits before attempting to practice.
This environmental medicine made its way into Islamic medical geography through Ibn Ridwan’s application of the Airs, Waters, Places framework to Egypt and into later European medicine through the concept of miasma, atmospheric pollution that corrupted the air and promoted epidemic disease. The framework predates germ theory by two millennia, but its core insight (that the environment acts on the body in medically significant ways) remains productive.
Contemporary medical historiography has acknowledged the continued relevance of this environmental framework. Jackson’s handbook identifies a “Hippocratic turn” in recent medical and health history — a revival of Hippocratic ways of thinking in which airs, waters, and places have attracted new scholarly scrutiny, moving the historical narrative beyond clinic-centered accounts to recover the tradition’s environmental and ecological dimensions.(Jackson (ed.), 2011)
The environmental commitment runs deep enough in the tradition to plausibly explain the school’s own movements. Jouanna argues that Hippocrates most likely left Cos in order to enrich his clinical experience by examining 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 already given by Galen in his portrait of the ideal physician.(Jouanna, 1999) The same environmental sensibility appears in the Speech of the Envoy’s account of the northern plague: when barbarian kings sent for Hippocrates from Thessaly, he questioned their messengers about the heat, winds, mist, and other unusual conditions area by area, declined to come, and used the climatological information to predict the plague’s spread to Greece and to instruct the Thessalians on how to protect themselves.(Jouanna, 1999) Whether or not the episode is historical in detail, it captures a method: predict by environment, intervene by regimen.
Greek Medicine’s Three Enduring Legacies
Bynum identifies three principles bequeathed by Greek medicine that shaped Western practice until the nineteenth century: humoralism, botanical pharmacology, and a secular approach to disease.(Bynum, William, 2008)
Humoralism, the framework in which health and disease turn on the balance among four bodily fluids (blood, yellow bile, black bile, phlegm), is treated in detail at humoral-theory. It was, in Bynum’s phrase, “the most powerful explanatory framework of health and disease available to doctors and laymen” until scientific medicine began to replace it in the nineteenth century.(Bynum, William, 2008)
The botanical pharmacopoeia that accompanied Hippocratic practice was consolidated by Dioscorides in the first century CE into a Materia Medica organized by plant properties and uses, which remained influential through the Renaissance.(Bynum, William, 2008) The Hippocratic connection between plant knowledge and systematic medicine helped legitimate herbalism as a learned, rather than merely folk, discipline.
The secular approach, the commitment to natural causation, is the tradition’s most enduring intellectual legacy. When Hippocrates or Galen faced a sick patient, they drew on their own knowledge and skills “in an attempt to bring about an act of healing at the bedside,” not through prayer or ritual but through observation, reasoning, and intervention in natural processes.(Bynum, William, 2008) This set the terms for what counted as medicine in the Western tradition, even as specific doctrines were repeatedly revised or abandoned.
The Legendary Hippocrates
Alongside the technical authority of the Corpus, there grew up a parallel legendary tradition that shaped how Hippocrates was received across cultures and centuries. By the first or second century CE, these stories had been given literary form in the Greek Pseudepigrapha — novelistic letters and speeches — and in a biography attributed to Soranus, both of which were treated in antiquity not as fiction but as documents of historical value.(Temkin, 1991) The legendary Hippocrates was a figure of moral as well as scientific authority: he was a model of honesty and courage, an educator who led physicians to humane behavior, and a very wise person — in short, a classical author and one of the pillars of culture, ranged with Homer and Thucydides.(Temkin, 1991)
Hippocrates’ confession in the Epidemics of a fatal diagnostic mistake — mistaking the fissures of a head injury for skull sutures, with the result that the patient’s head was not trephined in time — was cited by Celsus as an example of “a great man’s love of truth in great matters.” Quintilian, Plutarch, and the Emperor Julian all used the episode as a touchstone of intellectual honesty.(Temkin, 1991) Equally celebrated was the first aphorism, “Life is short, but the art is long,” which placed Hippocrates in the company of outstanding philosophers and was extended by Seneca and the Stoics far beyond its medical origins into a comment on the brevity of all human endeavor.(Temkin, 1991)
What distinguished this legendary Hippocrates from a purely religious or divine figure was his remaining emphatically human: a hero and sage, but not a god’s competitor. Unlike Asclepius, who became the most tenacious pagan competitor of Jesus, or Apollonius of Tyana, who was used as a pagan rival to Christ, Hippocrates remained the human head of a secular art.(Temkin, 1991) This restraint is, Temkin argues, one reason he survived the pagan-Christian transition intact. The legendary Hippocrates’s refusal of the Persian king — his reply to the satrap Hystanes that he had “no right to share the wealth of the Persians or to liberate from disease barbarians who are the enemies of the Greeks” — expressed a Panhellenic philanthropy bounded by national allegiance.(Temkin, 1991) One anonymous eulogy went further: Paetus’s letter to Artaxerxes portrayed Hippocrates as a descendant of Asclepius and Hercules who “purges the wide earth and the sea of beastly and fierce diseases” as Triptolemus had spread Demeter’s gifts — calling him “father of health, savior, mitigator of pain, leader of the science befitting a god.”(Temkin, 1991) Yet such near-divine language remained rhetorical. The biography attributed to Soranus showed curiously little interest in the content of Hippocratic medical doctrine, noting only the difficulty of identifying genuine works while lavishing attention on biographical exploits — suggesting a public more interested in the life of a great man than in his medical theories.(Temkin, 1991)
The Aphorisms attracted commentary that raised Hippocrates to a different kind of authority. An anonymous preface to a collection of Problems assigned Hippocratic aphorisms three levels of meaning: each had a precise limited significance; together the aphorisms formed a system in which each supported the others; and beyond that, they were “adapted not only to medicine but to all life in general,” being universal laws foretelling and regulating events — a reading that placed Hippocrates in the company of Plato.(Temkin, 1991) Hippocrates also earned legal authority outside medicine: the jurist Paul, writing around 200 CE, cited his authority on seven-month births to settle questions of legitimacy, recording that “a son born in the seventh month following a legitimate marriage must be held to be legitimate” on the strength of Hippocratic teaching.(Temkin, 1991)
Hippocrates’ influence was not confined to the Greek-speaking world. Already in his lifetime, both Plato and Aristotle referred to him as the physician par excellence.(Pormann (ed.), 2018) Jouanna’s philological survey makes the Athenian standing of the figure more concrete. In Plato’s Protagoras (set around 430 BCE), Socrates uses Hippocrates of Cos as a textbook example of a paradigmatic physician — parallel to Polyclitus of Argos and Phidias of Athens as paradigmatic sculptors — which establishes that by the end of the fifth century Hippocrates was already known for his teaching and was regarded as the most celebrated physician of the Periclean Age.(Jouanna, 1999) In the more mature Phaedrus, Plato has Phaedrus and Socrates invoke “Hippocrates of the Asclepiad family” as an authority on method, agreeing that one cannot satisfactorily comprehend the soul or the body apart from the nature of the universe.(Jouanna, 1999) Jouanna reads this as evidence both that Hippocrates’ teaching was known in detail in Athens — though he had never lived or taught there — and that medical thinking exerted a broader influence on the intellectual history of classical Greece, with a leading philosopher invoking a physician and the science of the body serving as model for the science of the soul.(Jouanna, 1999) Aristotle, the son of a doctor and a recommender of medical study to philosophers, picked up the same usage forty years later, citing Hippocrates in the Politics as a man great by reason of his science rather than his stature; by then the bare name “Hippocrates” sufficed without further qualification, a sign of unchallenged celebrity.(Jouanna, 1999) (Jouanna, 1999) Christians, Jews, and Muslims subsequently appropriated him in various ways; his influence in Arabic is arguably greater than in Latin, and his fame reached all the way to India and China.(Pormann (ed.), 2018) In the medieval Islamic world, Hippocrates became the most famous Greek physician, arguably more famous than Galen, exercising a power over the imagination of generations of Arab and Muslim physicians that went well beyond his textual authority.(Pormann (ed.), 2018)
Hippocratic Medicine and Christianity
Temkin’s central finding was that the conversion of the Roman world to Christianity did not force far-reaching accommodations upon Hippocratic medicine. He had initially assumed it would; his sources convinced him otherwise. He had underrated the strength of popular support for secular medicine, overrated the influence of philosophical and religious creeds on actual practice, and not sufficiently reckoned with how much latitude medicine left to the physician in private life.(Temkin, 1991) There is no good evidence that educated persons who had used Hippocratic doctors before converting to Christianity shunned them afterward; the question is rather when and how Hippocratic medicine moved into the purview of Christian theology and when Christian theologians began to make use of Hippocratic science.(Temkin, 1991)
Pagans and Christians, living together in late antiquity, shared some traditional ways of thought and faced the same physical realities. Both groups had a common notion of the principles of Hippocratic medicine, its relationship to body and mind, and its goal regarding human health and disease; both had to make use of the physician unless they rejected secular medicine altogether.(Temkin, 1991) At late antiquity’s broadest level, the parallel between medicine of the body and medicine of the soul — healing by diet, drugs, and surgery versus healing by reasoning and psychological techniques — was a commonplace shared across the pagan-Christian divide.(Temkin, 1991)
What Christianity introduced was a new category of difficulty. The naturalism of pre-Socratic philosophers and Hippocratic physicians had arisen in a pagan society that demanded respect for the gods while leaving much freedom for speculation about the divine, and that was secular in its orientation toward life in this world. Potential conflict existed between the natural explanation of disease and the concept of disease as imposed by God; between the Hippocratic view of the soul as corporeal (or nearly so) and Christian insistence on its immortality; and between the physician’s role as autonomous healer and his function as mere agent of God, the true healer.(Temkin, 1991) Jews had used wounds and diseases as symbols of sin and disobedience with an intensity the Greeks had not matched, and Jesus had compared himself to a physician when he said that those who are whole need not a physician but those who are sick.(Temkin, 1991)
There was no single “Christian attitude” toward Hippocratic medicine. Outspoken hostility coexisted with welcome acceptance, and one can only identify tendencies that integrated many existing views.(Temkin, 1991) What distinguished the sincere Christian doctor from his pagan counterpart was not a fundamental change in professional ethics but a new relationship to faith and its church.(Temkin, 1991) Hippocratic naturalism was accepted by the Christian church provided that nature was acknowledged as God’s creation rather than given a divine character of its own; on that condition, natural law presented no challenge to Christian theology.(Temkin, 1991)
The practical resolution was that the medical literature of late antiquity paid little attention to the existence of divinely caused diseases; physicians treated medicine of the body while supernatural diseases were left to priests and clergy. This division of labor was important for rendering Hippocratic medicine religiously neutral in practice, whatever theoretical tensions remained.(Temkin, 1991) Late-antique Hippocratic medicine deserves, in Temkin’s formulation, to be called neutral in one specific sense: it was neither polytheistic, Jewish, nor Muslim. Jews and Muslims could adopt it and add to it what their respective faiths demanded — as indeed they did. Modern scientific medicine has retained this character.(Temkin, 1991)
Yet the neutrality was never complete. Hippocratic naturalism was not neutral in the way mathematics could be. Even when stripped of frank polytheism, its remaining naturalism remained a foreign body in any radically Christian culture, because in Hippocratism nature was and remained the final power — and whether nature was considered God’s creation was a decision outside medicine’s own purview.(Temkin, 1991) For pagans, the coexistence of religious and secular healing did not involve a troubled conscience. For Christians it did, because the naturalistic basis of Hippocratic medicine gave it a non-Christian character that created a difficulty pagans had not faced.(Temkin, 1991)
The Greek tradition had viewed health as the highest human good; within a Christian culture oriented toward the kingdom of God, health became problematic. Healing was good — it was part of love for one’s neighbor, and Jesus had compared himself to a physician. But to be healed, unless by God and His servants, was not generally accepted as good. Disease could be well-deserved punishment for sin, or a test of faith, or a preparation for eternity.(Temkin, 1991) The Hippocratic doctor who converted to Christianity entered a new religious world, but his traditional science remained intact; what changed was personal orientation, not clinical method. As a human being he was transformed; as a physician, his practice did not have to undergo a revolution. What shook the world did not shake everything in it in equal measure.(Temkin, 1991)
The reception of Hippocrates in the Christian era involved a diminution of his cultural status alongside a preservation of his medical authority. Christian culture needed Hippocratic medicine but did not need Hippocrates as a culture hero, having its own apostles, saints, and theologians. In the eyes of strict Christians, he was not a real sage, as Isidore of Pelusium made clear, nor was he a perfect physician in the sense of the physician-saints who could heal both bodies and souls.(Temkin, 1991) Galen, rather than Hippocrates, drew the ire of Christian theologians, because Galen as spokesman in scientific matters had openly doubted the soul’s immortality and confessed to philosophical agnosticism; Hippocrates, by contrast, represented clinical medicine and medical ethics and carried no such baggage.(Temkin, 1991) Tertullian nonetheless acknowledged Hippocrates as a humane doctor, conceding that Hippocratic physicians had performed embryotomy not from cruelty but from compassion — convinced the fetus was a living being, they chose to kill it rather than have it dismembered alive.(Temkin, 1991)
A semantic change in the tradition’s self-understanding reflects the shift. The Hippocratic saying about the doctor harvesting sorrows from others’ miseries began as a complaint about the burden of the profession; by the fifth century at the latest it had been transformed into a professional demand: the good physician must make the misfortunes of others his own sorrow.(Temkin, 1991) The Hippocratic oath retained its moral force throughout antiquity and the Middle Ages in both East and West, and it is the oath that keeps Hippocrates’ name alive among a broad public that may never have heard of humoral pathology.(Temkin, 1991) By about 500 CE, a Christian paraphrase had also appeared, opening “Blessed be God the Father of our Lord Jesus Christ, who is blessed for ever and ever; I lie not” — substituting Christian for pagan invocations while preserving the oath’s ethical substance.(Temkin, 1991)
In Byzantium, the Souda of the tenth century praised Hippocrates’ books as honored “like utterances of a god,” singling out the Oath, Prognostic, and Aphorisms as the foremost works. Late in antiquity, an anonymous preface to the Aphorisms presented Hippocrates as “nature incarnate” fulfilling the divine mission of saving mankind — a formulation that created an unintentional parallel with the Johannine Word made flesh, producing what Temkin calls a christianized Hippocrates.(Temkin, 1991)
Reception in the Early Modern Period and Beyond
The period Bynum calls “library medicine” — the millennium between the fall of Rome and the Renaissance — was not intellectually passive.(Bynum, William, 2008) Byzantine, Islamic, and Latin scholars preserved and transmitted the Greek heritage while adding new observations and medicaments of their own. When Vesalius demonstrated in 1543 that Galen’s anatomical descriptions (many derived from animal dissection) did not accurately describe the human body, the authority of the Galenic-Hippocratic synthesis began to fracture, though humoral theory persisted in practice long after the anatomical errors were corrected.
The Enlightenment phase of Hippocratic reception preserved the patient-centered character of the tradition: before modern diagnostic technology, patients and physicians “spoke the same language and had similar conceptions of disease and its causes,” and diagnosis relied substantially on patients’ accounts of their own symptoms.(Bynum, William, 2008) This continuity with Hippocratic attention to the patient’s experience ended only with the emergence of hospital-based medicine in the early nineteenth century, when physical examination and postmortem correlation gave physicians access to a new world of objective signs that patients could not report.
By the end of the seventeenth century, the separation of Hippocrates from Galen seemed irreversible. For many, Hippocrates had come to be revered as a symbol of empiricism and practice, while Galen stood for rationalism and theory.(Pormann (ed.), 2018) Earlier, Francis Bacon had suggested that Hippocrates’ practice of taking a “history” of an individual patient’s illness in the form of notes might be applied to the study of nature more generally, linking the Hippocratic clinical record to the new experimental philosophy.(Pormann (ed.), 2018)
The figure of Sydenham illustrates the complexity of later Hippocratic reception. Called the “English Hippocrates” and described by Baglivi as “the profoundest observer after Hippocrates,“(Coulter, 1975) Sydenham revived Hippocratic observational method explicitly against the speculative physiologies of his contemporaries. He rejected Willis’s chemical interpretation of physiology in favor of a return to direct clinical experience.(Coulter, 1975) Harold Cook has argued that Sydenham’s Hippocrates was a Baconian collector of case studies, a compiler of medical detail, an inductivist, and the early founder of the true methods of natural history whose achievements had been devalued by rationalists like Galen.(Pormann (ed.), 2018) Yet the concept of “specific disease” that emerged from his work — the idea that diseases have universal features independent of the individual patient — was in tension with the individualist commitments of the Hippocratic tradition he claimed to continue.(Bynum, William, 2008)
The Philadelphia yellow fever epidemic of 1793 offers an instructive case study in how Hippocratic empiricism functioned as a methodological framework long after its ancient context had dissolved. As Thomas Apel has shown, most physicians turned to Hippocratic empiricism to understand the disease: they agreed that it was a local condition largely limited to the city’s boundaries, and that it tended to emerge in late summer through autumn — a period of heat, humidity, and torrential rain — in keeping with Hippocratic seasonal and meteorological reasoning. Yet those who favored miasmatic and those who favored contagionist explanations reached quite different conclusions about what these shared observations meant, demonstrating that Hippocratic empiricism could license divergent aetiological inferences from identical clinical data.(Pormann (ed.), 2018)
Nutton’s work on Hippocratic ethics has also reframed how scholars understand the function of the Oath. Jackson’s handbook notes that Nutton’s analysis emphasizes the reputational gain that moral injunctions — commitments to do no harm, to keep confidences, and to refrain from certain practices — would have brought to healers in ancient Greek society who committed to them: the Oath’s ethical provisions were, in part, a competitive strategy in a pluralistic healing marketplace, conferring the kind of moral credibility that attracted patients and patrons in a world where medicine had no regulatory authority.(Jackson (ed.), 2011)
Modern medical historians have been central to clarifying what Hippocratic medicine was and was not. Temkin credits Ludwig Edelstein with bringing an increased awareness of the “otherness” of former periods to the history of medicine, stimulating study of the philosophical, religious, and social conditions under which ancient medical ideas evolved, while also cautioning that this contextual approach sometimes overrated the influence of general ideas and creeds at the expense of medicine’s own intellectual autonomy.(Temkin, 1991) Jacques Jouanna, whose 1999 biography Hippocrates remains the fullest scholarly account of the tradition, argued that Aristotle’s relationship to the Hippocratic texts was that of “an attentive reader.”(Hynek Bartoš and Vojtěch Linka, 2024) Vivian Nutton, whose Ancient Medicine (revised 2023) is the standard reference for ancient medicine in the English-speaking world, has emphasized the diversity and internal tensions of the Corpus over its unity, and concluded that the Hippocratic Corpus as we know it is substantially “a renaissance construct.”(Hynek Bartoš and Vojtěch Linka, 2024) Wesley D. Smith’s The Hippocratic Tradition (1979) remains the essential study of how the tradition was constructed through commentary rather than inherited from a single founding source.
The historiography of ancient medicine carries its own disciplinary history. For much of the twentieth century, professional study of Greco-Roman medicine was dominated by a philological paradigm, in which the primary task was the editing, translating, and grammatical analysis of ancient texts rather than their social, cultural, or scientific contextualization.(Jackson (ed.), 2011) The field was perceived as the province of classicists and retired physicians: a domain for those who combined Greek scholarship with medical training, rather than for professional historians of medicine trained in social or cultural methods.(Jackson (ed.), 2011) By the early twenty-first century this picture had substantially changed. The study of ancient medicine has been flourishing in the Anglophone world, producing work of breadth and sophistication that was not conceivable within the older philological paradigm.(Jackson (ed.), 2011) A related challenge confronts the field: to open up the history of ancient medicine to neighboring disciplines (social history, anthropology, religious studies, history of philosophy) whose methods and questions enrich the philological core without displacing it.(Jackson (ed.), 2011)
(Hynek Bartoš and Vojtěch Linka, 2024): the Hippocratic Corpus is the final product of a long process of canonization with a strong accretive tendency, which gradually absorbed practically all extant non-fragmentary medical literature from the Classical period. Nutton goes so far as to conclude that the Hippocratic Corpus as we know it “is a renaissance construct”. (Hynek Bartoš and Vojtěch Linka, 2024): Modern debate on the issue practically ceased during the second half of the twentieth century, with a number of scholars independently coming to the conclusion that none of the Hippocratic writings can with reasonable certainty be ascribed to Hippocrates. Accordingly, “statements prefaced by ‘Hippocrates said …’ or ‘Hippocrates knew …’, all too common in general writings about early medicine, are fundamentally misplaced.” (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. (Hynek Bartoš and Vojtěch Linka, 2024): A human is healthy when an effective blending prevents any particular bodily constituent from manifesting itself more than necessary. Disease and pain, on the other hand, arise from the disruption of the proper equilibrium, when one bodily constituent prevails over the others or separates itself from the blending, and when a bodily part becomes excessively hot or cold or dry or wet. (Hynek Bartoš and Vojtěch Linka, 2024): Hence the natures of these people differ, and the difference concerns the very thing in the body that is hostile to cheese and is stirred up and set in motion by it. Those in whom such a humour happens to be present in greater quantity and to exert more power in the body will naturally suffer more. But if cheese were bad for human nature in general, it would harm all people (VM 20.6). (Hynek Bartoš and Vojtěch Linka, 2024): All those who have undertaken to speak or write about medicine, having laid down as a hypothesis for their account hot or cold or wet or dry or anything else they want, [1] narrowing down the primary cause of diseases and death for human beings and laying down the same one or two things as the cause in all cases, clearly go wrong in much that they say (VM 1.1, i.570.1–7 L.). (Hynek Bartoš and Vojtěch Linka, 2024): For one must aim at a measure; but you will find no measure—nor number nor weight besides—by referring to which you will know with precision, except the feeling of the body (VM 9.1–3, i.588.4–590.1 L.). (Hynek Bartoš and Vojtěch Linka, 2024): The first thesis is that (1) disease and death will have to be analysed on the basis of a reduction of the body to its basic components (ch. 1). The second thesis, (2), seeks to ground medicine and cure on a prior knowledge of the nature or being of the body conceived as a study of the origins of human beings and of the way they were generated (ch. 20). … In both cases, the critique takes an anti-reductionist stance. (Hynek Bartoš and Vojtěch Linka, 2024): the author argues that medicine gains its credibility as an art as it examines in detail two spheres of phenomena in the body that are responsible for health and disease. The first relates to the powers; the second to the structures of the body (VM 22.1, i.626.6–7 L.). … Powers are defined as ‘the acuity and strength of the humours’ (VM 22.1, i.626.8–9 L.). (Hynek Bartoš and Vojtěch Linka, 2024): the author does not hesitate to give to the art of cooking the name of ‘medicine’, establishing thus an ancient origin for his own art (VM 3.6). This identification is based on a teleological and a methodological consideration … The two arts aim at securing the good functioning of specific types of body, and they use similar means by seeking the appropriate chemical process in nutrition that will neutralise possible harming effects. (Hynek Bartoš and Vojtěch Linka, 2024): the reason we should examine external animal parts and artefacts is to discover the functions such structures support. This is the direction that the author urges us to take in order to search for an explanation in the domain of medicine. … What he does not know and what is invisible and beyond his comprehension is their function. (Hynek Bartoš and Vojtěch Linka, 2024): Aristotle’s father Nicomachus was a court physician to the Macedonian king Amyntas iii (reigning from c. 393 to c. 370bce). Although Nicomachus died at an early age, it is reasonable to assume that Aristotle was brought up in a medical environment and that he received some medical education (formal or informal) before he left for Athens to enter Plato’s Academy. (Hynek Bartoš and Vojtěch Linka, 2024): It is the business of the student of nature to inquire into the first principles (archai) of health and disease. For neither health nor disease can come to be in things deprived of life. So generally speaking, most of those who study nature end by dealing with medicine, while those of the doctors who practise their art in a more philosophical manner (philosophōterōs) take their medical principles from the study of nature. (Hynek Bartoš and Vojtěch Linka, 2024): In some cases, such accounts are taken into consideration as authoritative sources in terms of evidence or theory that needs to be supplemented and refined by Aristotle’s own observations and arguments. In other cases, however, medical endoxa are mentioned anonymously alongside opinions of pre-Socratic philosophers and other thinkers relevant to Aristotle’s accounts. Occasionally, conceptions and terminology of medical origin are adopted and tacitly integrated into Aristotle’s own expositions. (Hynek Bartoš and Vojtěch Linka, 2024): Regarding the Hippocratic texts most likely to have been known to Aristotle, van der Eijk (2012, 1520 and 2022,10, n. 26) suggests the following works: Nat. Hom., Aph., Epid. 2, 5 and 7, Loc. Hom., VM, Morb. 2, Genit. Nat. Pue. Morb. 4, Vict., Flat., and Aër. (Hynek Bartoš and Vojtěch Linka, 2024): Now the ancients who first began philosophising about nature were examining the material origin and that sort of cause: what matter is and what sort of thing it is, and how the whole comes to be from it and what moves it … Aristotle’s objection against his predecessors is that descriptions of the formation of parts … that rely on the description of the elements, their properties, and their natural motions … are insufficient for explaining the presence of such bodily parts (Part. an. 1.1, 640b5–16). (Hynek Bartoš and Vojtěch Linka, 2024): Perilli is sceptical about any direct influence of the medical texts on Aristotle, instead suggesting that most of the parallels can be explained by reference to shared common knowledge among the educated or to common (but no longer extant) sources. (Hynek Bartoš and Vojtěch Linka, 2024): The idea that Aristotle was “an attentive reader of Hippocrates”, as Jouanna puts it, goes back to Galen, who took for granted that, in some of his theories and accounts, Aristotle drew on the very same medical sources and authorities that Galen was familiar with under Hippocrates’ name. And since Galen believed that at least some of the texts were written by Hippocrates himself, he called Aristotle an “interpreter of Hippocrates’ reasoning on nature”.
