Threatened by Carthage and dominated by Hiketas, the tyrant of Leontini, Syracusans sent an appeal for help to their mother city, Corinth. By a unanimous vote Corinth selected Timoleon to set sail for Sicily with a few leading citizens of Corinth and a small troop of Greek mercenaries. After defeating Hiketas, Timoleon put order to Syracuse' affairs and established a democratic government. He repelled Carthage in several wars, ending with a treaty which divided the island. Timoleon then retired without any title or office, though he remained practically supreme. He became blind before his death, but when important issues were under discussion he was carried to the assembly to give his opinion, which was usually accepted. When he died the citizens of Syracuse erected a monument to his memory, afterward surrounded with porticoes, and a gymnasium called Timoleonteum.
