Achelous

(Achelo′us) was a river god, and the rival of Hercules in his love for Deianira. To decide who should have the bride, Hercules and Achelous had recourse to a wrestling bout, the fame of which extends through all the intervening centuries. In this fierce struggle, Achelous changed himself into the form of a bull and rushed upon his antagonist with lowered horns, intending to hurl him aside. Hercules eluded the onset, and seizing one of the huge horns, held it so firmly that it was broken off by the furious efforts of Achelous to free himself. He was defeated, and finally turned himself into a river, which has since been known by his name.
