Labours of Hercules, the 12 labours, or tasks, assigned to the Greco-Roman legendary hero Hercules (Heracles) by King Eurystheus.
Traditionally, Hercules was the son of Zeus, the chief deity among the Greek gods, and Alcmene, a mortal princess whom Zeus tricked into sleeping with him. Hercules married Megara, daughter of the king of Thebes, with whom he had children. Driven mad by Zeus’s vindictive wife, the goddess Hera, Hercules killed Megara and their children. To atone, he consulted the oracle at Delphi and was told to become the servant of King Eurystheus.
It was Eurystheus who imposed upon Hercules the famous Labours, later arranged in a cycle of 12, usually as follows:
Having completed the Labours, Hercules was free but went on to perform other noteworthy feats.
According to some accounts, after Hercules had completed the first 10 tasks, King Eurystheus declared that the second and fifth tasks did not count, either because he had assistance or because he received payment. He then demanded that Hercules complete two more tasks, which are the 11th and 12th labours.
