The next day, the real Amphitryon returned and slept with his wife. One night while Amphitryon was away, Zeus came to Alcmena disguised as her husband. Heracles was the son of Zeus (pronounced ZOOS) and Alcmena (pronounced alk-MEE-nuh), the wife of Amphitryon (pronounced am-FI-tree-uhn), a distinguished Greek warrior and heir to the throne of Tiryns (pronounced TEER-ins). In Greek mythology, only two figures with half-mortal, half-god parentage-Heracles and Dionysus (pronounced dye-uh-NYE-suhs)-became fully immortal (able to live forever) and were worshipped as gods. Only supernatural forces could defeat him, and it was magic that ended his mortal life. When the fury passed, though, Heracles was full of sorrow and guilt for what he had done and ready to accept any punishment for his misdeeds.
Easily angered, his sudden outbursts of rage often harmed innocent bystanders. Heracles (called Hercules by the Romans) was not blessed with great intelligence, but his bravery made up for any lack of cunning. Besides tremendous physical strength, he had great self-confidence and considered himself equal to the gods. The greatest of all heroes in Greek mythology, Heracles was the strongest man on earth.
