<P> The Hippocratic Corpus (Latin: Corpus Hippocraticum) is a collection of around seventy early medical works from Alexandrian Greece . It is written in Ionic Greek . The question of whether Hippocrates himself was the author of any of the treatises in the corpus has not been conclusively answered, but current debate revolves around only a few of the treatises seen as potentially by him . Because of the variety of subjects, writing styles and apparent date of construction, the Hippocratic Corpus could not have been written by one person (Ermerins numbers the authors at nineteen). The corpus came to be known by his name because of his fame, possibly all medical works were classified under' Hippocrates' by a librarian in Alexandria . The volumes were probably produced by his students and followers . </P> <P> The Hippocratic Corpus contains textbooks, lectures, research, notes and philosophical essays on various subjects in medicine, in no particular order . These works were written for different audiences, both specialists and laymen, and were sometimes written from opposing viewpoints; significant contradictions can be found between works in the Corpus . Notable among the treatises of the Corpus are The Hippocratic Oath; The Book of Prognostics; On Regimen in Acute Diseases; Aphorisms; On Airs, Waters and Places; Instruments of Reduction; On The Sacred Disease; etc . </P> <P> The Hippocratic Oath, a seminal document on the ethics of medical practice, was attributed to Hippocrates in antiquity although new information shows it may have been written after his death . This is probably the most famous document of the Hippocratic Corpus . Recently the authenticity of the document's author has come under scrutiny . While the Oath is rarely used in its original form today, it serves as a foundation for other, similar oaths and laws that define good medical practice and morals . Such derivatives are regularly taken today by medical graduates about to enter medical practice . </P> <P> The Travels of Sir John Mandeville reports (incorrectly) that Hippocrates was the ruler of the islands of "Kos and Lango" (sic), and recounts a legend about Hippocrates' daughter . She was transformed into a hundred - foot long dragon by the goddess Diana, and is the "lady of the manor" of an old castle . She emerges three times a year, and will be turned back into a woman if a knight kisses her, making the knight into her consort and ruler of the islands . Various knights try, but flee when they see the hideous dragon; they die soon thereafter . This is a version of the legend of Melusine . </P>
