Ancient Hellas is often lauded as the birth place of modern science and philosophy. Certainly in the arts of medicine and healing, this is true. Hippokrátēs of Kos (Ἱπποκράτης) is seen by many as the founding father of medicine. Hippokrátēs was alive from 460 BC to about 370 BC. In his lifetime, he set about to advancing the systematic study of clinical medicine, summing up the medical knowledge of previous schools, and prescribing practices for physicians through the Hippocratic Corpus and other works (although he Corpus itself was most likely not written by him, but assembled in and slightly after his time). Hippokrátēs separated the discipline of medicine from religion, believing and arguing that disease was not a punishment inflicted by the Theoi but rather the product of environmental factors, diet, and living habits. Much of his theories came from his very basic understanding of the human body: in Hippokrátēs' time, it was forbidden to cut into a corpse, even for research.
