From Greek mythology, Achelous was a River God who took three different shapes when he chose. he could take the form of a bull, a speckled serpent, a bull headed man like the minotaur. He wrestled with Hercules for the hand of Dejanira and while in the latter form, lost a horn. The blood that fell to the ground from the horn became the Sirens, while the horn itself was discovered by Naiads who took and filled it with flowers and fruit. Classical myth tells us that Achelous’ horn was then presented to Plenty who made it her cornucopia (The horn of plenty).
