(Ἀπολλοκράτης), the elder son of Dionysius, the Younger, was left by his father in command of the island and citadel of Syracuse, but was compelled by famine to surrender them to Dion, about B. C. 354. He was allowed to sail away to join his father in Italy. (Plut. Dio 37, &c., 56; Strab. vi. p.259; Nepos, Dion, 5 ; Aelian, Ael. VH 2.41.) Athenaeus speaks (vi. pp. 435, f., 436, a.) of Apollocrates as the son of the elder Dionysius; but this must be a mistake, unless we suppose with Kühn (ad Ael. l.c.), that there were two persons of this name, one a son of the elder and the other of the younger Dionysius.
