Hiero II of Syracuse

Hiero II (Greek: Ἱέρων Β΄; c. 308 BC – 215 BC), also called Hieron II, was the Greek tyrant of Syracuse, Greek Sicily, from 275 to 215 BC, and the illegitimate son of a Syracusan noble, Hierocles, who claimed descent from Gelon. He was a former general of Pyrrhus of Epirus and an important figure of the First Punic War. He figures in the story of famed thinker Archimedes shouting "Eureka".
