3. A son of Actor and Aegina, a step-brother of Aeacus, and husband of Polymele, by whom he became the father of Patroclus. He resided at Opus, and took part in the expedition of the Argonauts (Hom. Il. 11.785, 16.14, 18.326). Some accounts call his mother Damocrateia, and a daughter of Aegina; and instead of Polymele they call his wife Sthenele or Periapis (Apollod. 3.13.8; Schol. ad Pind. Ol. 9.107; Strab. p. 425; comp. V. Fl. 1.407; Eustath. ad Hom. p. 112). When Patroclus, during a game, had slain the son of Amphidamas, Menoetius fled with him to Peleus in Phthia, and had him educated there (Hom. Il. 11.770, 23.85, &c.; Schol. ad Pind. Ol. 9.104). Menoetius was a friend of Heracles. (Diod. 4.39.)
