(Ὑλαῖος), that is, the woodman, the name of an Arcadian centaur, who was slain by Atalante, when, in conjunction with Rhoetus, he pursued her. (Apollod. 3.9.2; Callim. Hymn. in Dian. 221; Aelian, Ael. VH 13.1.) According to Propertius (1.1, 13) Hylaeus had also attacked and severely wounded Meilanion, the lover of Atalante. (Comp. Ov. Ars Am. 2.191.) According to some legends, Hylaeus fell in the fight against the Lapithae, and others again said that he was one of the centaurs slain by Heracles. (Virg. Georg. 2.457; Serv. ad Aen. 8.294; comp. Hor. Carm. 2.12, 5.) One of the dogs of Actaeon likewise bore the name of Hylaeus. (Ov. Met. 3.213.)
