ENIPEUS
an Oceanid and a son of Oceanus and Tethys.
A river-god in Thessaly, he was beloved by Tyro, the daughter of Salmoneus. Poseidon, who was in love with her, assumed the appearance of Enipeus, and thus visited her, and she became by him the mother of twins, Pelias and Neleus. (Apollod. i. 9. § 8.) Ovid (Metamorphoses vi) relates that Poseidon, having assumed the form of Enipeus, begot by Iphimedeia two sons, Otus and Ephialtes.
Another river-god of the same name occurs in Elis, who is
likewise connected with the legend about Tyro. (Strab. viii. p.
356.)
