A mythological hero, son of Zeus and of the mortal woman Alcmene. He was endowed with extraordinary strength and achieved many feats. The best known are the Twelve Labours of Hercules. An episode of his tenth labour is probably depicted: the fight of Hercules with the giant shepherd Cacus. The girl running behind is probably Cacus's sister pursued by Fury, the goddess of vengeance, persecuting her for having betrayed her brother.
