muse

The Muses were the nine Greek goddesses who presided over the arts (including music) and literature. A shrine to the Muses was called in Latin a museum. An artist or poet about to begin work would call on his particular Muse to inspire him, and a poem itself might begin with such a call; thus, Homer's Odyssey begins, "Sing to me of the man, Muse" (that is, of Odysseus). Today a muse may be one's special creative spirit, but some artists and writers have also chosen living human beings to serve as their muses.
