Zeus, << zoos, >> was the ruler of the gods in Greek mythology. Zeus was a sky and weather god, especially associated with rain, thunder, and lightning. The Greeks believed he was all-knowing and all-seeing. The Greeks considered Zeus a father figure and a protector, especially of guests and strangers. The Roman god Jupiter was equivalent to Zeus.
Zeus was the son of Cronus and Rhea, members of an earlier race of ruling gods called the Titans. Zeus and the other children of Cronus defeated the Titans. Zeus then took Cronus’ place and ruled from his home on Mount Olympus. He headed a family of 12 major gods and goddesses called the Olympians. Some lesser gods also lived on Olympus. Zeus’s brothers were the gods Hades and Poseidon. Hades ruled the underworld, and Poseidon ruled the seas. The goddesses Demeter, Hera, and Hestia were Zeus’s sisters.
At the time Zeus was introduced in Greece, the religion of that area was based on fertility. Each community had a major fertility goddess and a male god associated with her. Zeus eventually took the place of many of these male gods, and became the husband or lover of the goddesses. Later, Hera became Zeus’s wife, and other goddesses took a lesser status.
Zeus had many love affairs with goddesses and mortal women and fathered many children. His children included the goddess Aphrodite; the gods Apollo, Dionysus, and Hermes; and the mortal heroes Perseus and Heracles (Hercules in Latin). The goddess Athena was born out of Zeus’s head.
In art, Zeus is depicted as bearded and majestic, often holding a thunderbolt. The eagle and the oak tree were symbols associated with Zeus.
