Il. xiv. 115, &c.; The Theogony of Apollodorus I; Description of Greece by Pausanias iv. 35. § 1, vi. 20. § 8, 21. § 7; Hygin. Fab. 175.) It should be observed that his name is sometimes written Portheus, and under this name he is mentioned by Antonius Liberalis who calls him a son of Ares.

From Smith's Dictionary of Greek and Roman Biography and MythologyFrom The Theogony of Apollodorus I
Calydon and Aeolia, daughter of Amythaon, had daughters, Epicaste and Protogonia, who had Oxylus by Ares. And Agenor, son of Pleuron, married Epicaste, daughter of Calydon, and begat Porthaon and Demonice, who had Evenus, Molus, Pylus, and Agrius by Ares. Evenus begat Marpessa, who was wooed by Apollo, but Idas, son of Aphareus, carried her off in a winged chariot which he received from Poseidon.
