Hippocrates was a Greek physician born in 460 BC on the  island of Cos, Greece. He became known as the founder of medicine  and was regarded as the greatest physician of hisâ¦ time. He based  his medical practice on observations and on the study of the human  body.
Plato mentions Hippocrates in two of his dialogues: in Protagoras, Plato describes Hippocrates as Hippocrates of Kos, the Asclepiad; while in Phaedrus, Plato suggests that Hippocrates the Asclepiad thought that a complete knowledge of the nature of the body was necessary for medicine. Hippocrates taught and practiced medicine throughout his life, traveling at least as far as Thessaly, Thrace, and the Sea of Marmara.
