Mnemosyne Titan daughter of Uranus and Gaea. Goddess of memory and remembrance and the inventress of language and words. Mnemosyne was also a goddess of time. She represented the rote memorization required before the introduction of writing, to preserve the stories of history and sagas of myth.
Mnemosyne slept with Zeus for nine consecutive nights, thus birthing the nine Muses. Nine Muses are usually named: Calliope (heroic or epic poetry), Clio (history), Erato (lyric or love poetry), Euterpe (music or flutes), Melpomene (tragedy), Polyhymnia (sacred poetry or mime). Terpsichore (dancing and choral song), Thalia (comedy), and Urania (astronomy).
