ACHALEOUS, ACHELEOUS, ACHELOYS. Achelous, a river god, was one of Dejanira's suitors. Hercules challenged him to combat, and Achelous changed himself into different forms, last of all into a bull. Hercules broke off one of his horns, defeated him, and won Dejanira (Met IX.4-88; OM IX.1-872).
The Monk mentions the breaking of Achelous's horn, MkT 2106. Lady Philosophy also tells of the fight, Bo IV, Metr 7.43-50.
The forms are variants of OF Acheloüs. Acheloys appears in medial position, MkT 2106; Achaleous occurs in Bo IV, Metr 7.43, and Acheleous appears in Bo IV, Metr 7.45.
