Hippocrates of Kos (c.?460 - c.?370 BC) was a Greek physician of the classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referred to as the "Father of Medicine" and the Hippocratic school of medicine revolutionized ancient Greek medicine, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession. Our publishing house brings to the attention of readers the treatise «Of the epidemics», attributed to Hippocrates, in the translation from ancient Greek into English made in the nineteenth century by Francis Adams, a Scottish medical doctor and translator of many Greek, Roman and Arabic ancient medical works. It is the first true historical, medical and scientific treatise of antiquity on the theme of epidemics.
