Definition: The Greek god Zeus was the top Olympian god in the Greek pantheon. After he took credit for rescuing his brothers and sisters from their father Cronus, Zeus became king of heaven and gave his brothers Poseidon and Hades the sea and the underworld for their domains.
Zeus was the husband of Hera, but he had many affairs with other goddesses, mortal women, and female animals. Zeus mated with, among others, Aegina, Alcmena, Calliope, Cassiopea, Demeter, Dione, Europa, Io, Leda, Leto, Mnemosyne, Niobe, and Semele.
In the Roman pantheon, Zeus is known as Jupiter.
