At eight months he strangled two serpents that had entered his nursery. During a fit of anger he killed his wife and three kids. Not succeeding to find peace, he consulted the Oracle of Delphi that told him to go to Euristheus who would give him 12 labours to perform to pay for his sin. These labours took Heracles all over the world and the Underworld. The first labour was to kill and skin a lion that could not be killed by any weapon. Heracles fought with his club, and even though the club broke, he succeeded in killing the lion. He skinned the lion and wore its hide.
