Hippocrates, Volume IV: Nature of Man (Loeb Classical Library, No. 150)

Hippocrates, said to have been born in Cos in or before 460 BCE, learned medicine and philosophy; travelled widely as a medical doctor and teacher; was consulted by King Perdiccas of Macedon and Artaxerxes of Persia; and died perhaps at Larissa. Apparently he rejected superstition in favour of inductive reasoning and the study of real medicine as subject to natural laws, in general and in individual people as patients for treatment by medicines and surgery. Of the roughly 70 works in the 'Hippocratic Collection' many are not by Hippocrates; even the famous oath may not be his. But he was undeniably the 'Father of Medicine'.

The works available in the Loeb Classical Library edition of Hippocrates are the following. Volume I: Ancient Medicine. Airs, Waters, Places. Epidemics 1 and 3. The Oath. Precepts. Nutriment.
