Zeus (known as Jupiter by the Romans) was the son of Cronus and Rhea. He killed/banished* his father and mother and was named king of Heaven. Zeus was a very powerful god, and could turn himself into humans, animals, vegetables, and minerals. Although when he was altered, he hardly fooled gods, he had the power to fool humans. He eventually married his sister, Hera, and lived to regret it. He was constantly unfaithful to Hera, and the gave her reason to be very bitter. Soon Hera took action, and with help from Poseidon and Apollo, made Zeus a prisoner of Olympus. Zeus became furious and soon Nereid, a female Titan, decided to release him since she did not want to see another civil war on Olympus. Zeus inflicted punishment on all his captures, but Hera received the worst. She was hung from the sky with a golden bracelet on each wrist and an anvil on each ankle. Poseidon and Apollo were sent temporarily as servants to an earthly king, Laomedon, for whom they built the city of Troy. Zeus continued to rule his family, and he also kept the stars and planets in order, made laws, enforced oaths, and pronounced oracles.
