High Quality Content by WIKIPEDIA articles! Ancient Greek medicine revolved around the theory of humours. The most important figure in ancient Greek medicine is the physician Hippocrates, known as the "Father of Medicine", who established his own medical school at Cos. Hippocrates and his students documented many conditions in the Hippocratic Corpus, and developed the Hippocratic Oath for physicians, still in use today. The writings of Hippocrates, and others, like Socrates, had a lasting influence on Islamic medicine and Medieval European medicine until many of their findings eventually became obsolete from the 14th century onwards.
