Zeus is the "Father of Gods and men" who rules the Olympians of Mount Olympus as a father rules the family according to the ancient Greek religion. He is the god of sky and thunder in Greek mythology. Zeus is etymologically cognate with and, under Hellenic influence, became particularly closely identified with Roman Jupiter.
Zeus is the child of Cronus and Rhea, and the youngest of his siblings. In most traditions he is married to Hera, although, at the oracle of Dodona, his consort is Dione: according to the Iliad, he is the father of Aphrodite by Dione.
He is known for his erotic escapades. These resulted in many godly and heroic offspring, including Athena, Apollo and Artemis, Hermes, Persephone (by Demeter), Dionysus, Perseus, Heracles, Helen of Troy, Minos, and the Muses (by Mnemosyne); by Hera, he is usually said to have fathered Ares, Hebe and Hephaestus.
His weapon is the thunderbolt, and his bird is the eagle. The central figure of the myths, Zeus epitomizes their complexity. At times he is divine and represents a pure, eternal sense of justice; at other times, he is capricious and cruel.
