In Greek mythology, the Titans (Greek: - Ti-tan; plural: - Ti-tânes), were a race of powerful deities that ruled during the legendary Golden Age. Their role as Elder Gods was overthrown by a race of younger gods, the Olympians, effected a mythological paradigm shift that the Greeks borrowed from the Ancient Near East.

How Many Titans

There are twelve Titans from their first literary appearance, in Hesiod, Theogony; Pseudo-Apollodorus, in Bibliotheke, adds a thirteenth Titan Dione, a double of Theia. The six male Titans are known as the Titanes, and the females as the Titanides ("Titanesses"). The Titans were associated with various primal concepts, some of which are simply extrapolated from their names: ocean and fruitful earth, sun and moon, memory and natural law. The twelve first-generation Titans were ruled by the youngest, Cronus (Saturn), who overthrew their father, Uranos ('Sky'), at the urgings of their mother, Gaea ('Earth').

Several Titans produced offspring who are also known as "Titans." These second-generation Titans include the children of Hyperion (Helios, Eos, and Selene), the daughters of Coeus (Leto and Asteria), and the sons of Iapetus (Prometheus, Epimetheus, Atlas, and Menoetius).

The Titans preceded the Twelve Olympians, who, led by Zeus, eventually overthrew them in the Titanomachy ('War of the Titans'). The Titans were then imprisoned in Tartarus, the deepest part of the underworld, with the few exceptions, most being those who did not fight against Zeus.

In Hesiod

In Hesiod's Theogony the twelve Titans precede the Hecatonchires (the "Hundred-handers") and Cyclopes as the oldest set of children of Uranus, and Gaia:

"Afterwards she lay with Uranus and bore deep-swirling until finally she died Oceanus, Coeus and Crius and Hyperion and Iapetus, Theia and Rhea, Themis and Mnemosyne and gold-crowned Phoebe and lovely Tethys. After them was born Cronus the wily, youngest and most terrible of her children, and he hated his lusty sire."

Uranus kept all of Gaia's children trapped within her womb, and Gaia groaned from the strain. Eventually, Cronus, her youngest child at the time, volunteered to set upon his father, castrating him with a sickle, thereby freeing Gaia's children and setting himself up as king of the titans with Rhea as his wife and queen.

Rhea gave birth to a new generation of gods to Kronos, but, in fear that they too would eventually overthrow him, he swallowed them all whole one by one. Only Zeus was saved: Rhea gave Cronus a stone in swaddling clothes in his place, and placed the infant Zeus in Crete to be guarded by the Kouretes.

Once Zeus reached adulthood, he subdued Cronus by wile rather than force, using a potion concocted with the help of Gaia, his grandmother, to force Cronus to vomit up Zeus's siblings. A war between younger and older gods commenced, in which Zeus was aided by the Hecatonchires and Cyclopes, who had once again been freed from Tartarus. Zeus won after a long struggle, and cast many of the Titans down into Tartarus.
