Zeus: The God of Thunder

In Greek mythology, the primordial deities,  are the first gods and goddesses born from the void of Chaos. Hesiod's first (after Chaos) are Gaia, Tartarus, Eros, Erebus, Hemera and Nyx. The primordial deities Gaia and Uranus give birth to the Titans, and the Cyclopses. The

Titans Cronus and Rhea give birth to Zeus, Poseidon, Hades, Hestia, Hera and Demeter who overthrew the Titans. The warring of the gods ends with the reign of Zeus.

Zeus is the sky and thunder god in ancient Greek religion, who rules as king of the gods on Mount Olympus. His mythologies and powers are similar, though not identical, to those of Indo-European deities such as Jupiter, Perkunas, Perun, Indra and Thor.

Zeus is the child of Cronus and Rhea, the youngest of his siblings to be born, though sometimes reckoned the eldest as the others required disgorging from Cronus's stomach. In most traditions, he is married to Hera, by whom he is usually said to have fathered Ares, Hebe and Hephaestus.  At the oracle of Dodona, his consort was said to be Dione, by whom the Illiad states that he fathered Aphrodite. Zeus was also infamous for his erotic escapades. These resulted in many divine and heroic offspring, including Athena, Apollo, Artemis, Hermes, Persephone, Dionysus, Perseus, Heracles, Helen of Troy, Minos and the Muses.

The Birth:

Cronus sired several children by Rhea: Hestia, Demeter, Hera, Hades and Poseidon, but swallowed them all as soon as they were born, since he had learned from Gaia and Uranus that he was destined to be overthrown by his son as he had previously overthrown Uranus, his own father.

When Zeus was about to be born, Rhea sought Gaia to devise a plan to save him, so that Cronus would get his retribution for his acts against Uranus and his own children. Rhea gave birth to Zeus in Crete, handing Cronus a rock wrapped in swaddling clothes, which he promptly swallowed.

After reaching manhood, Zeus forced Cronus to disgorge first the stone then his siblings in reverse order of swallowing.  In some versions, Zeus cut Cronus's stomach open. Then Zeus released the brothers of Cronus, the Hecatonchires and the Cyclopes, from their dungeon in Tartarus, 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, his brothers and sisters, 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 who 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 who died.

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, Eris, Enyo and Angelos as their daughters. The conquests of Zeus among nymphs and the mythic mortal ancestor of Hellenic dynasties are famous. Olympian mythography even credits him with unions with Leto, Demeter, Metis, Themis, Eurynome and Mnemosyne. Other relationships with immortals included Dione and Maia. Among mortals were Semele, Io, Europa and Leda .

Many myths render Hera as jealous of his desirous conquests and a consistent enemy of Zeus's mistresses and their children by him. For a time, a nymph named 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.
