The treatise On Ancient Medicine (Greek: Περὶ Ἀρχαίας Ἰατρικῆς) is perhaps the most intriguing and compelling work of the Hippocratic Corpus. The Corpus itself is a collection of about sixty writings covering all areas of medical thought and practice. Traditionally associated with Hippocrates, (c. 460 BC – c. 370 BC) the father of Western medicine, philological evidence now suggests that it was written over a period of several centuries and stylistically seems to indicate that it was the product of many authors dating from about 450-400 B.C. On the basis of its diverse arguments regarding the nature of medical therapeutics, the Hippocratic Corpus could be divided into four divisions or groups.
