As a Titan daughter of Uranus, Mnemosyne was also a goddess of time. She represented the rote memorisation required to preserve the stories of history and the sagas of myth before the introduction of writing. In this role she was the mother of the Muses, who were originally patron goddesses of poets of the oral tradition.
Finally Mnemosyne was a minor oracular goddess like her sister Titans. She presided over the underground oracle of Trophonius in Boeotia.
