A son of Caucon, Glaucon, or Pyrgeus (Aelian, V. H. i. 24; Paus. v. 5. § 4), by Astydameia. He was a grandson of Poseidon (the Schol. ad Callim. Hymn. in Jov. 39, calls him a son of Poseidon), and a rival of Heracles both in his strength and his powers of eating, but he was conquered and slain by him. His tomb was believed to exist at Phigalia. (Athen. x. p. 41 , &c.; Paus. l. c.; Eustath. ad Hom. p. 1523.) [Cf. LEPREA.]
