(Ἀρκεσίλαος), a son of Lycus and Theobule, was the leader of the Boeotians in the Trojan war. He led his people to Troy in ten ships, and was slain by Hector. (Hom. Il. 2.495, 15.329; Hyg. Fab. 97.) According to Pausanias (9.39.2) his remains were brought back to Boeotia, where a monument was erected to his memory in the neighbourhood of Lebadeia. A son of Odysseus and Penelope of the name of Arcesilaus is mentioned by Eustathius. (Ad Hom. p. 1796.)
