Pancratis was the daughter of Alöeus and Iphimedea. She and her mother were abducted by Thracian pirates to Naxos, where two of the pirate leaders killed each other in a duel over her. Her name means 'all strength', from pas (pan), 'all' and cratos, 'strength', 'might'. This was no doubt intended generally as a propitious name, but she was actually the winner of the trial of strength between the two men.
