The man-headed bull on the reverses is thought to be the River-god Acheloös, the father of the Sirens, whose cultus was wide-spread throughout the Greek world.
The man-headed bull, crowned on the later coins by a winged Nike, clearly an agonistic type, is characteristic of many Campanian coins, and may have been generally understood as symbolical of Acheloös.
