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.
Hippocrates was succeeded by Gelo, who, in 484, conquered Syracuse and moved his seat of government there. His brother Hiero was given control over Gela. When Theron of Agrigento conquered Himera and a Carthaginian army disembarked in Sicily to counter him, he asked for help from Gela and Syracuse. Gelo and Hiero were victorious in the subsequent battle of Himera, in which the Carthaginian leader Hamilcar lost his life.
