Greek physician from the island of Kos, traditionally called the father of Western medicine.
See it on the Technology & Medicine map →How it works
Hippocrates taught on Kos, off today's Turkish coast, around 400 BC. About 60 texts, the Hippocratic Corpus, carry his name, though many authors wrote them over a century or more. They argue that diseases have natural causes, not divine ones, and stress careful observation, prognosis, diet and rest. They include the theory of four humors, later expanded by Galen. The Hippocratic Oath, an early code of medical ethics, was probably written by followers, not by him.
Why it mattered
He became the symbol of medicine as a rational, ethical profession; many doctors still take oaths modeled on the one bearing his name.
Legacy and how we know
Legacy: Plato and Aristotle mention him as a famous doctor, and the Hippocratic Corpus survives in medieval manuscripts. Reliable biography is scarce.
Still unknown or debated
Which Hippocratic texts, if any, he wrote himself is unknown, and much of his life story comes from later legend.
Connections (4)
▸Ancient Egyptian medicine influenced the Greek medicine of HippocratesMostly agreed
The connection
Egyptian doctors were famous in the Greek world: Homer praised them, and Herodotus described their specialists. Greek traders, visitors and physicians met Egyptian remedies, and some ingredients and recipes reappear in Hippocratic texts. Greek medicine borrowed practical knowledge but built its own theory of natural causes.
When and how
The eastern Mediterranean, about 700 to 400 BC, partly through Greek trading towns in Egypt such as Naukratis.
How sure are we?
Some Hippocratic gynecological remedies closely resemble those in Egyptian papyri, and Greek writers openly credit Egyptian medicine.
Debates and open questions
How much of Greek medicine was borrowed rather than developed independently is debated; direct textual links are few.
▸Mesopotamian medicine may have influenced HippocratesDebated
The connection
Babylonian diagnostic texts list symptoms and predict outcomes, much as Hippocratic writings stress prognosis. Some scholars see Babylonian influence, perhaps through Persian-ruled Ionia, near Kos, where Greek and Near Eastern learning met. Others think the resemblance reflects similar observation, not borrowing.
When and how
Possible contact in the eastern Mediterranean and the Persian Empire, about 600 to 400 BC.
How sure are we?
Scholars such as Mark Geller note parallels in format and some disease descriptions, but no direct borrowing is proven.
Debates and open questions
Whether Hippocratic doctors knew Babylonian texts at all, and how ideas crossed the language barrier, remains open.
▸Hippocrates was systematised by GalenWell documented
The connection
Six centuries after Hippocrates, Galen made himself the champion and interpreter of the Hippocratic writings. He wrote long commentaries on them, developed their theory of four humours (blood, phlegm, yellow bile, black bile), and fused it with anatomy and his own experiments into one system that dominated medicine for 1,400 years.
When and how
Pergamon and Rome, about AD 150–200, working from Hippocratic texts collected and edited at Alexandria.
How we know
Galen's surviving commentaries on Hippocratic works such as Epidemics and Aphorisms, and his treatise On the Doctrines of Hippocrates and Plato.
Debates and open questions
Which 'Hippocratic' texts Hippocrates actually wrote is unknown; Galen shaped the image of Hippocrates we inherit, perhaps partly in his own image.
▸Hippocrates practised the chest-listening revived by the Stethoscope (Laennec)Mostly agreed
The connection
Hippocratic texts describe pressing an ear to the chest and shaking patients to hear fluid splash. Doctors largely abandoned such listening for centuries. In 1816 René Laennec, reluctant to put his ear to a young woman's chest, rolled paper into a tube, heard the heart more clearly, and later credited Hippocrates.
When and how
Hippocratic writings, about 400 BC; Necker Hospital, Paris, 1816, where Laennec made his first stethoscope.
How sure are we?
The Hippocratic text On Diseases describes chest sounds, and Laennec's 1819 book discusses the Hippocratic shaking method, called succussion, directly.
Debates and open questions
Whether Hippocrates inspired Laennec or he recognized the heritage afterward is unclear; the link is a revival, not continuous practice.
