Hippocrates Timeline

(c. 460 BCE – c. 370 BCE)

Hippocrates of Kos (c. 460 – c. 370 BCE) was an ancient Greek physician widely regarded as the Father of Medicine. He founded a medical school on the island of Kos and revolutionized healthcare by separating medicine from superstition and religion, promoting observation, diagnosis, and rational treatment. The Hippocratic Corpus, a collection of medical writings attributed to him and his followers, and the Hippocratic Oath, an ethical code for physicians, remain profoundly influential in medicine today.

Life and Early Years

Birth of Hippocrates on Kos

460 BC

Hippocrates is traditionally believed to have been born around 460 BC on the Aegean island of Kos. He came from a family that claimed descent from Asclepius, the god of medicine, and his father Heracleides was reportedly a physician who gave him early training in the healing arts.

Family lineage and Asclepiad tradition

460 BC

Hippocrates belonged to the Asclepiads, a hereditary guild or family of physicians tracing their origins to Asclepius. This tradition meant he likely received formal training through apprenticeship within his family, learning remedies, rituals, and practical medical techniques from an early age.

Early education in medicine and philosophy

450 BC

As a young man Hippocrates received a broad education encompassing medicine, gymnastics, rhetoric, and philosophy. Sources suggest he studied under his father and later under Democritus of Abdera and Gorgias of Leontini, absorbing both scientific speculation and the art of persuasion.

Study at the Asclepieion of Kos

445 BC

Hippocrates is said to have trained at the Asclepieion, or healing temple, on his home island of Kos. There patients gathered for treatment and cures were recorded, giving aspiring physicians exposure to many diseases and an empirical foundation for medical practice.

Travels across Greece to study disease

440 BC - 420 BC

According to ancient biographers, Hippocrates traveled widely across the Greek world, including Thessaly, Thrace, Propontis, and possibly Scythia and Egypt. His journeys exposed him to diverse climates and diseases, material later reflected in the treatise Airs, Waters, Places.

Medicine and Practice

Practice during the Plague of Athens era

430 BC - 426 BC

Tradition holds that Hippocrates responded to devastating epidemic outbreaks in the Greek world during this period, including plague-like fevers. Later legends credit him with controlling epidemics through measures such as purifying air with bonfires, though the accounts are largely apocryphal.

Advancement of rational, non-supernatural medicine

420 BC

Hippocratic medicine rejected explanations attributing illness to gods or curses, insisting that every disease had a natural cause. This epistemological shift toward observation, diagnosis, and natural causation is often regarded as the founding moment of Western scientific medicine.

Recording case histories in the Epidemics

410 BC - 380 BC

The books of the Epidemics contain day-by-day descriptions of individual patients' symptoms, including famous case studies such as those of Philiscus, Cnidus, and Thasus. They represent some of the oldest surviving clinical records and demonstrate rigorous longitudinal observation of disease.

Emphasis on dietetics and lifestyle in treatment

400 BC

Hippocratic therapy centered on regimen—diet, exercise, sleep, bathing, and environmental adjustment—with drugs and surgery reserved as needed. Treatises like Regimen in Health and On Regimen detailed how physicians should tailor lifestyle prescriptions to each patient's constitution.

Systematization of surgical techniques

400 BC

Corpus treatises such as On Fractures and On Joints describe reduction of dislocations, treatment of fractures including the Hippocratic bench for traction, management of head injuries, and drainage of empyema. These works show a remarkably sophisticated level of surgical practice.

Authorship of Prognostic and clinical observation method

400 BC

The Prognostic taught physicians to predict the course of illness by observing signs such as facial appearance, fever patterns, and sleep. Emphasis on careful daily observation of patients made prognosis a central skill of the Coan physician and founded clinical medicine as a discipline.

Alleged service during wars and epidemics in Thessaly

395 BC - 385 BC

Later traditions place Hippocrates treating patients during military campaigns and pestilences in Thessaly, where several cities honored him. Ancient accounts claim Larisa granted him citizenship and honors for his services during outbreaks of contagious disease.

Medical Works and Teachings

Teaching medicine to students and apprentices

430 BC - 370 BC

Throughout his career Hippocrates taught pupils through lectures, demonstrations, and bedside instruction. Many works of the Hippocratic Corpus appear to be teaching texts written for students, laying out methods of diagnosis, prognosis, and treatment in systematic form.

Establishment of a medical school on Kos

430 BC

Hippocrates established a school of medicine on Kos that emphasized systematic observation, clinical training, and rational explanation over superstition. The Coan school became one of the two great centers of Greek medicine alongside its rival at Cnidos.

Composition of On Airs, Waters, and Places

420 BC

This treatise argued that environment—climate, water quality, winds, and local customs—shapes the health and character of populations. It marks one of the earliest attempts at a systematic medical geography and epidemiological analysis.

Development of the theory of the four humors

420 BC

Hippocratic medicine articulated the doctrine of four humors—blood, phlegm, yellow bile, and black bile—whose balance determined health and whose imbalance caused disease. This framework dominated European medicine for nearly two thousand years until the rise of modern pathology.

Formulation of principles of medical ethics

400 BC

Works such as Physician, Decorum, and Precepts codified physician conduct: professionalism, compassion, discretion, fair fees, and humility before the limits of medicine. These writings created an enduring ideal of the physician as both skilled craftsman and moral agent.

Composition of the Oath attributed to Hippocrates

400 BC

The Hippocratic Oath set ethical obligations for physicians, including duties to teachers, prohibitions on harmful drugs and abortion, and requirements of confidentiality. It became the archetype of medical ethics and continues to influence modern professional oaths.

Compilation of the Hippocratic Corpus begins

400 BC - 300 BC

The roughly sixty treatises of the Hippocratic Corpus were composed and compiled between about 420 and 350 BC, though most are by students and followers rather than Hippocrates himself. The collection spans surgery, gynecology, epidemics, dietetics, ethics, and medical philosophy.

Writing of On the Sacred Disease

400 BC

In this influential treatise epilepsy, then called the sacred disease, was declared no more divine than other illnesses but instead a natural disorder of the brain. The work is celebrated as a landmark argument for naturalistic explanations of disease against supernatural interpretations.

Legacy and Influence

Recognition as the greatest physician of his age

400 BC

Already during his lifetime Hippocrates acquired fame throughout Greece; Plato twice refers to him in the Protagoras and Phaedrus, calling him an Asclepiad and comparing him to great sculptors. Contemporaries regarded him as the foremost practitioner and teacher of medicine of the era.

Death of Hippocrates at Larisa in Thessaly

370 BC

Hippocrates died around 370 BC, traditionally in Larisa, Thessaly, at an advanced age estimated near ninety years. Ancient sources differ on the exact year, with estimates ranging from about 380 to 350 BC, but all agree he lived to old age and died greatly honored.

Tomb of Hippocrates becomes site of veneration

360 BC

Ancient writers report that bees made honey on Hippocrates' tomb near Larisa, honey sought after for healing children's sores. The story reflects how quickly his memory passed into legend and how his grave became a symbol of his enduring healing power.

Establishment of the Hippocratic school's lasting canon

300 BC

By the Hellenistic period scholars at Alexandria organized the writings of the Coan school into a canonical corpus attributed to Hippocrates, cementing his name as the authority of Greek medicine and preserving the texts that shaped medical education for millennia.

Galen champions Hippocratic medicine

150 AD - 210 AD

The Roman-era physician Galen revered Hippocrates, writing commentaries on his works and building his own vast medical system upon Hippocratic humoral theory. Galen's endorsement transmitted Hippocratic medicine intact to Byzantine, Islamic, and medieval European physicians.
