daughter of Hieron II., king of Syracuse, was married to a Syracusan named Zoippus. Though her husband was a man of a quiet and unambitious character, and had taken no part in the schemes of Andranodorus and Themistus, after the death of Hieronymus, the unhappy Heraclea was nevertheless involved in the sentence of proscription passed on the whole house of Hieron at the instigation of Sopater, and was put to death together with her two daughters. It is said that the people relented, and revoked the sentence against her, but not until it was too late. (Liv. 24.26.)
