Muses

Any of the nine daughters of Mnemosyne and Zeus, who were regarded as the goddesses of inspiration of literature, art, or science. Their names are:

Calliope, the muse of epic poetry, 

Clio, the muse of history, 

Erato, the muse of lyric poetry,

Euterpe, the muse of song,

Melpomene, the muse of tragedy,

Polyhymnia, the muse of hymns,

Terpsichore, the muse of dance,

Thalia, the muse of comedy, and 

Urania, the muse of astronomy.

The word Muse comes from Latin, from Greek Mousa. There are Greek dialect forms mosa and moisa. As to the further origins of this form, a clue is provided by the name of Mnemosyne, the goddess of memory and mother of the Muses. Her name is the Greek noun mnemosune "memory," which comes from *mna-, an extended form of the Greek and Indo-European root *men-, "to think." This is the root of the English word amnesia (from Greek), mental (from Latin), and mind (from Germanic).
