This is the name of a class of primordial GIANTS in the classical mythology of Greece and Rome. The TITANS were the progeny of URANUS and GAIA and originally were twelve in number: six sons named COEUS/KOIOS, CRIUS/KREIOS/CREIUS, HYPERION, JEPETUS/IAPETUS, and OKEANUS/OCEANUS; and six daughters, known as the TITANIDES, named MNEMOSYNE, PHOEBE/PHIOBE, RHEA/RHEIA, TETHYS, THEIA, and THEMIS. Their names and number varied, including EURIBIA/EURIBIE, CLYMENE/KLYMENE, and DIONE during the classical period, but the Italian poet Boccaio (1313-1375) mentions others who, in the classical period, were not counted as TITANS but as other classes of GIANT, including BRAREUS, TYPHON, TYPHEUS, ENCELADUS, ENCELADUS, EGON, ATLAS, ASTREUS, and ALOUS. These GIANTS were the siblings of the FURIES, THE CYCLOPES, and the HUNDRED-HANDED-GIANTS. The TITANS were so ugly that URANUS, their father, threw them into TARTARUS, or the belly of GAIA in some accounts.
The TITANS rebelled against their father, URANUS, and CRONUS took a sickle and castrated him. CRONUS, however, knew that one of his children would also rebel against him and he so set out to devour each one as it emerged. However, the last, ZEUS, was hidden by his mother RHEA, who persuaded CRONUS to vomit up the other children, the OLYMPIAN GODS, who waged a war against the TITANS and eventually threw them into Tartarus.
