ABSTRACT
The god of a river in northwestern Greece. He was a son of Oceanus and Tethys. Achelous wrestled with Heracles for the hand of Deianira, but in spite of his power to change shape was defeated. He turned into a bull, but Heracles broke off one of his horns. To recover this, Achelous gave Heracles a horn from the goat Amalthea, which had suckled Zeus.
