The Labors of Herakles is a series of tasks performed by the Greek hero Herakles () as a penance for a terrible crime he committed. These tasks required great strength and courage. For the most part, they involved killing fierce animals and horrible monsters. The Labors were said to have been devised by Hera, the goddess of marriage. She hated Herakles because he was a bastard son of her husband Zeus. She hoped these tasks would kill him. Herakles however performed them with great success, and, in the process, became very famous. The Labors of Herakles probably had their origin in the religious and magical practices of prehistoric man. They are the subject of ancient and modern art.
