Mnemosyne

Titaness of memory. Mnemosyne ("Memory") was the daughter of Uranus and Gaea. She was the abstract personification of memory. In Roman myths, she was called Moneta.

By Zeus, she was the mother of nine daughters, known as the Muses. Zeus slept with Mnemosyne for nine nights, and one year later, she gave birth to the nine wondrous daughters. Mnemosyne named them as Cleio, Euterpe, Thaleia, Melpomene, Terpischore, Erato, Polyhymnia, Urania and Calliope, with Calliope being her eldest daughter.
