1. King of Arne in Boeotia, and husband of Philomedusa, is called in the Iliad (vii. 8, &c.) korunêtês, because he fought with no other weapon but a club. He fell by the hand of the Arcadian Lycurgus, who drove him into a narrow defile, where he could not make use of his club. Erythalion, the friend of Lycurgus, wore the armour of Areïthous in the Trojan war. (Hom. Il. vii. 138, &c.) The tomb of Areïthous was shewn in Arcadia as late as the time of Pausanias. (viii. 11. § 3.)
2. There is another mythical personage of this name in the Iliad (xx. 487).
