Achelous

god
Ἀχελῷος
Greatest river god, father of the Sirens

Achelous was the god of the mightiest river in Greece and father of the Sirens — he wrestled Heracles for the right to marry Deianira.

The Myth

Achelous was the most powerful river god, honoured as the father of all freshwater. He could shape-shift into a bull, a serpent, and a man with a bull's face. When he and Heracles competed for Deianira, Achelous fought in bull form. Heracles broke off one of his horns, which became the Cornucopia (Horn of Plenty). He was the father of the Sirens by one of the Muses.
