There is, clearly, no straightforward Roman prototype for this odd reverse. However, there is an argument to be made that it is loosely based on Maximianus' issue showing Hercules slaying the Hydra (Calicó 4656 ff.), with the hero's club being reduced to a small round object and the monster to the aegis-shaped object on a stick.
