Adeimantus

(Ἀδείμαντος).

1. The son of Ocytus, the Corinthian commander in the invasion of Greece by Xerxes. Before the battle of Artemisium he threatened to sail away, but was bribed by Themistocles to remain. He opposed Themistocles with great insolence in the council which the commanders held before the battle of Salamis. According to the Athenians he took to flight at the very commencement of the battle, but this was denied by the Corinthians and the other Greeks. (Hdt. 8.5, 56, 61, 94; Plut. Them. 11.)

2. The son of Leucolophides, an Athenian, was one of the commanders with Alcibiades in the expedition against Andros, B. C. 407. (Xen. Hell. 1.4.21.) He was again appointed one of the Athenian generals after the battle of Arginusae, B. C. 406, and continued in office till the battle of Aegospotami, B. C. 405, where he was one of the commanders, and was taken prisoner. He was the only one of the Athenian prisoners who was not put to death, because he had opposed the decrec for cutting off the right hands of the Lacedaemonians who might be taken in the battle. He was accused by many of treachery in this battle, and was afterwards impeached by Conon. (Xen. Hell. 1.7.1, 2.1.30_32; Paus. 4.17.2, x.. § 5; Dem. de fals. leg. p. 401.; Lys. c. Alc. pp. 143, 21.) Aristophanes speaks of Adeimantus in the "Frogs" (1513), which was acted in the year of the battle, as one whose death was wished for; and he also calls him, apparently out of jest, the son of Leucolophus, that is, "White Crest." In the " Protagoras" of Plato, Adeimantus is also spoken of as present on that occasion (p. 315c.).

3. The brother of Plato, who is frequently mentioned by the latter. (Apol. Socr. p. 34a., de Rep,. ii. p. 367e. p. 548d. c.)
