Here is an image of the Asparas in Angkor Wat, Cambodia.
Here is an introduction from Wikipedia:
Apsaras are beautiful, supernatural female beings. They are youthful and elegant, and superb in the art of dancing. They are often 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.
