The Apsaras are beautiful supernatural spirits in the Hindu and Buddhist mythologies. Their natural element is the Air and are great dancers. They usually perform to the gods or seduce men (sometimes to disrupt their meditation) or take care of fallen heroes. Read the Wikipedia entry to get a better overview. What I find most interesting about the Apsaras is that you can see them sculpted everywhere in some Hindu temples, often with incredible details.
