Apsara

From Wikipedia:

An Apsara (also spelled as Apsarasa) is a female spirit of the clouds and waters in Hindu and Buddhist mythology.  English translations of the word "Apsara" include "nymph," "celestial nymph," and "celestial maiden."

Apsaras are beautiful, supernatural female beings. They are youthful and elegant, and superb in the art of dancing. They are often the wives of the Gandharvas, the court musicians of Indra. They dance to the music made by the Gandharvas, usually in the palaces of the gods, entertain and sometimes seduce gods and men. As ethereal beings who inhabit the skies, and are often depicted taking flight, or at service of a god, they may be compared to angels.

Apsaras are sometimes compared to the muses of ancient Greece, with each of the 26 Apsaras at Indra's court representing a distinct aspect of the performing arts.
