(Πορθάων).

1. A son of Agenor and Epicaste, was king of Pleuron and Calydon in Aetolia, and married to Euryte, by whom he became the father of Oeneus, Agrius, Alcathous, Melas, Leucopeus, and Sterope. (Hom. Il. 14.115, &c.; Apollod. 1.7.7, &c.; Paus. 4.35.1, 6.20.8, 21.7; Hyg. Fab. 175.) It should be observed that his name is sometimes written Portheus (Heyne ad Apollod. l.c.), and under this name he is mentioned by Antonius Liberalis (2) who calls him a son of Ares.
