7.Heracles and his twelve laborWhen Hercules grew up and had become a great warrior, he married Megara. They had two children. Hercules and Megara were very happy, but life didn't turn out for them the way it does in the movie. Hera sent a fit of madness to Hercules that put him into so great a rage, he murdered Megara and the children. When Hercules regained his senses and saw the horrible thing that he had done, he asked the god Apollo to rid him of this pollution. Apollo commanded the hero to do certain tasks as a punishment for his wrongs, so that the evil might be cleansed from his spirit. Apollo had many divine responsibilities. As Phoebus, he was the sun god, and every day he drove the chariot of the sun across the sky. He was the god of healing and music. Finally, Apollo was a god of prophecy: the Greeks believed that Apollo knew what would happen in the future, and that he could advise people how to act. Hercules hurried to the temple where Apollo gave such advice. It was in the town of Delphi and was called the Delphic oracle. Apollo said that in order to purify himself for the spilling of his family's blood, he had to perform 10 heroic labors (this number would soon be increased to 12). Hercules got even more bad news. Apollo declared that he had to go to the city of Tiryns. The king of Tiryns was Eurystheus. Eurystheus had a reputation for being mean, and Hercules knew that the king would give him a tough time. The hero had to serve Eurystheus for twelve years while he performed the Labors. There was some good news, though. When the tasks were completed, Apollo said, Hercules would become immortal. Unlike other men, instead of dying and going to the Underworld of Hades, he would become a god.13.Why did Hercules had to complete 12 labors?
