In the ancient Greek religion, Zeus (Ancient Greek: Ζεύς, Zeús; Modern Greek: Δίας, Días) is the "Father of Gods and men" who rules the Olympians of Mount Olympus as a father rules the family. He is the god of sky and thunder in Greek mythology. His Romancounterpart is Jupiter and Etruscan counterpart is Tinia.

　　Zeus is the child of Cronus and Rhea, and the youngest of his siblings. In most traditions he is married toHera, although, at the oracle of Dodona, his consort is Dione: according to the Iliad, he is the father ofAphrodite 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 fatheredAres, Hebe and Hephaestus.

　　As Walter Burkert points out in his book, Greek Religion, "Even the gods who are not his natural children address him as Father, and all the gods rise in his presence." For the Greeks, he was the King of the Gods, who oversaw the universe. As Pausanias observed, "That Zeus is king in heaven is a saying common to all men". In Hesiod's Theogony Zeus assigns the various gods their roles. In the Homeric Hymns he is referred to as the chieftain of the gods.

　　His symbols are the thunderbolt, eagle, bull, and oak. In addition to his Indo-European inheritance, the classical "cloud-gatherer" also derives certain iconographic traits from the cultures of the Ancient Near East, such as the scepter. Zeus is frequently depicted by Greek artists in one of two poses: standing, striding forward, with a thunderbolt leveled in his raised right hand, or seated in majesty.

　　King of the gods

　　After reaching manhood, Zeus forced Cronus to disgorge first the stone (which was set down at Pytho under the glens of Parnassus to be a sign to mortal men, the Omphalos) then his siblings in reverse order of swallowing. In some versions, Metis gave Cronus an emetic to force him to disgorge the babies, or Zeus cut Cronus' stomach open. Then Zeus released the brothers of Cronus, the Gigantes, the Hecatonchires and the Cyclopes, from their dungeon inTartarus, killing their guard, Campe.

　　As a token of their appreciation, the Cyclopes gave him thunder and the thunderbolt, or lightning, which had previously been hidden by Gaia. Together, Zeus and his brothers and sisters, along with the Gigantes, Hecatonchires and Cyclopes overthrew Cronus and the other Titans, in the combat called the Titanomachy. The defeated Titans were then cast into a shadowy underworld region known as Tartarus. Atlas, one of the titans that fought against Zeus, was punished by having to hold up the sky.

　　After the battle with the Titans, Zeus shared the world with his elder brothers, Poseidon and Hades, by drawing lots: Zeus got the sky and air, Poseidon the waters, and Hades the world of the dead (the underworld). The ancient Earth, Gaia, could not be claimed; she was left to all three, each according to their capabilities, which explains why Poseidon was the "earth-shaker" (the god of earthquakes) and Hades claimed the humans that died (see alsoPenthus).

　　Gaia resented the way Zeus had treated the Titans, because they were her children. Soon after taking the throne as king of the gods, Zeus had to fight some of Gaia's other children, the monsters Typhon and Echidna. He vanquished Typhon and trapped him under Mount Etna, but left Echidna and her children alive.

　　Zeus and Hera

　　Zeus was brother and consort of Hera. By Hera, Zeus sired Ares, Hebe and Hephaestus, though some accounts say that Hera produced these offspring alone. Some also include Eileithyia and Eris as their daughters. The conquests of Zeus among nymphs and the mythic mortal progenitors of Hellenicdynasties are famous. Olympian mythography even credits him with unions with Leto, Demeter, Dione and Maia. Among mortals were Semele, Io, Europaand Leda (for more details, see below) and with the young Ganymede (although he was mortal Zeus granted him eternal youth and immortality).

　　Many myths render Hera as jealous of his amorous conquests and a consistent enemy of Zeus' mistresses and their children by him. For a time, a nymphnamed Echo had the job of distracting Hera from his affairs by talking incessantly, and when Hera discovered the deception, she cursed Echo to repeat the words of others.
