Step-by-step explanation:
As punishment for killing his family, Hercules went to King Eurystheus, King of Tiryns. In Greek mythology, Hercules, also known as Heracles, was tasked with completing the Twelve Labors as atonement for his actions which included tremendous feats like slaying the Nemean Lion and capturing Cerberus, the dog of the underworld. These labors were commanded by Eurystheus, to whom Hercules was made subservient as punishment by the Olympian gods.
