A king of the Lapithae, a son of Ares and Chryse, the daughter of Halmus, succeeded Eteocles, who died without issue, in the government of the district of Orchomenos, which he called after himself Phlegyantis. (Paus. ix. 36. § 1; Apollod. iii. 5. § 5.) By Chryse he became the father of Coronis, who became by Apollo the mother of Asclepius. Enraged at this, Phlegyas set fire to the temple of the god, who killed him with his arrows, and condemned him to severe punishment in the lower world. (Hom. Hymn. xv. 3; Pind. Pyth. iii. 14; Apollod. iii. 10. § 3, ii. 26. § 4; Serv. ad Aen. vi. 618; Stat. Theb. i. 713.) According to another tradition Phlegyas had no children, and was killed by Lycus and Nycteus. (Apollod. iii. 5. § 5,) Strabo (ix. p. 442) calls him a brother of Ixion.
