(Λέπρεα), a daughter of Pyrgeus, from whom the town of Lepreum, in the south of Elis, was said to have derived its name. (Paus. 5.5.4.) Another tradition derived the name from Lepreus, a son of Caucon, Glaucon, or Pyrgeus (Aelian, Ael. VH 1.24; Paus. 5.5.4), 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. 10.41 , &c.; Paus. l.c.; Eustath. ad Hom. p. 1523.)
