Titans, in Greek mythology, the sons and daughters of Uranus (Coelus) and Gsea (Terra). They were Oceanus, Cceus, Crius, Hyperion, Japetus, Cronus, Theia, Rhea, Themis, Mnemosyne, Phoebe, and Tethys. According to the most generally received account, Uranus feared his offspring, and as fast as they were born threw them into Tartarus. Gaea endeavored to persuade them to free her and themselves from this oppressive treatment. Cronus, armed with a sickle made by his mother, unmanned his father, and thus secured liberty and power for himself and his brothers. Marrying his sister Rhea, he begot three sons and three daughters, but, having been told that he would be destroyed by one of his own children, swallowed them as soon as they were born. Rhea concealed Zeus (Jupiter), the youngest, in a cave in Crete, giving to Cronus instead a stone wrapped in swaddling clothes. "When Zeus had grown up, he was enabled by stratagem to make his father vomit up the stone and the five children he had swallowed. Supplied by the Cyclops with thunder and lightning, and aided by the Centimani, Zeus carried on a war against the Titans for ten years, and at length triumphed.

The Titans, with the exception of Oceanus, were confined for ever in a subterranean dungeon, where they were guarded by the Centimani. The name of Titans was also given to their descendants.
