Terpsichore is the greek muse of Lyric Poetry and Dance. Her name translates to "delight of dancing" from the greek τερπέω ("delight") and χoρός ("dance"). She is one of the nine muses, daughters of Mnemosyne (memory) and Zeus according to the Theogony by Hesiod. She is often depicted in art with a lyre and people dancing (as can be seen in the lower right of this picture).

O Muses, o high genius, aid me now!
O memory that noted what I saw,
Now shall your true nobility be seen!

-Dante
