A Dictionary of Greek and Roman biography and mythology

(Θεαρίδης), a Syracusan, son of Hermocrates and brother of Dionysius the elder, tyrant of Syracuse. He is first mentioned in B. C. 390, when he was appointed by Dionysius to succeed his brother Leptines in the command of the fleet. The next year he commanded an expedition to the Liparaean islands, where he captured ten ships belonging to the Rhegians. Again in B. C. 388 he was chosen by his brother to conduct the magnificent procession which Dionysius sent to the Olympic festival. (Diod. xiv 102, 103, 109.)
