Mnemosyne — Classical Greek Myth Library

Zeus lay with Mnemosyne (Memory), daughter of Uranus and Gaia, for nine successive nights apart from the other gods. When the year turned, she bore nine daughters—alike in mind, song, and carefree hearts—near snowy Olympus, or in Pieria in the *Theogony*’s opening frame. They are the Muses: Cleio, Euterpe, Thaleia, Melpomene, Terpsichore, Erato, Polyhymnia, Urania, and Calliope (eldest, and Hesiod’s especial patron for kings and epic). From their birth they delight Zeus’s halls with song: they hymn the race of gods, the earth, and the laws of the immortals. Whoever the Muses love is gifted speech that softens quarrels and makes a king’s judgments straight; shepherds and poets they teach to tell what is, what will be, and what was. Hesiod himself claims they met him on Helicon, gave him a staff of laurel, and breathed song into him so he might celebrate the blessed ones—truth mixed, he warns, with the power to speak fictions that sound like truth. Catalogue the Muses’ birth as the Hesiodic union of Zeus and Mnemosyne: nine nights, nine sisters of memory and song, foundation of poetic authority in the classical tradition.
