In Greek mythology, the Titans (Ancient Greek: Τιτᾶνες, Tītânes; singular: Τιτάν, Tītā́n) were the deities that preceded the Olympians. According to the Theogony of Hesiod, they were the twelve children of the primordial deities Uranus (Sky) and Gaia (Earth). The six male Titans were Oceanus, Coeus, Crius, Hyperion, Iapetus, and Cronus, and the six female Titans (called the Titanesses; Ancient Greek: Τιτανίδες, Tītānídes; singular: Τιτανίς, Tītānís) were Theia, Rhea, Themis, Mnemosyne, Phoebe, and Tethys.
After Cronus married his sister Rhea, she bore the first generation of Olympians: the six siblings Zeus, Hera, Poseidon, Demeter, Hades, and Hestia. Certain other children of the Titans, such as Prometheus, Atlas, Helios, and Leto, are sometimes also called Titans.
