(Ἡσιόνη), a daughter of Laomedon, and consequently a sister of Priam. When Troy was visited by a plague and a monster on account of Laomedon's breach of promise, Laomedon, in order to get rid of these calamities, chained Hesione to a rock, in accordance with the command of an oracle, where she was to be devoured by wild beasts. Heracles, on his return from the expedition against the Amazons, promised to save her, if Laomedon would give him the horses which he had received from Zeus as a compensation for Ganymedes. Laomedon again promised, but did not keep his word. (Hom. Il. 5.649, &c.; Diod. 4.42; Apollod. 3.12.7.) Hesione was afterwards given as a slave to Telamon, by whom she became the mother of Teucrus. Priam sent Antenor to claim her back, and the refusal on the part of the Greeks is mentioned as one of the causes of the Trojan war. (Dares, Phryg. 4, &c.) According to Tzetzes (ad Lycoph. 467), Hesione, already in pregnancy by Telamon, fled from his ship to Miletus, where king Arion found her and her newly-born son, Trambelus, whom he brought up as his own child.

There are two other mythical personages of this name, one a daughter of Danaus, and by Zeus the mother of Orchomenus (Schol. ad Apollon. Rhod. 1.230), and the other the wife of Nauplius, and the mother of Palamedes, Oeax, land Nausimedon. (Apollod. 2.1.5.)
