Titans (male) and titanids (female) in Greek Mythology, are among the entities that faced Zeus and the other Olympic gods in their rise to power . Other opponents were the giants, Typhon and Orion. Of the various Greek poems of the Classical Age about the war between the gods and the titans, only one survived. This is the Theogony attributed to Hesiod. Also the essay On music attributed to Plutarch, mentions in passing a lost epic poem titled Titanomaquia ("War of the Titans") and attributed to the blind Thracian bard, Tamiris, a legendary character. In addition, the Titans played an important role in the poems attributed to Orpheus. Although only fragments of the orphic accounts are preserved, they reveal interesting differences in relation to the hesiodic tradition.
The titans do not form a homogeneous set. These are, in general, very old deities or "proto-gods" (first gods) who, for one reason or another, continued to have a certain validity within classical Greek myths and, when constituting the genealogical scheme of the gods, were included among the descendants of Uranus.
