Harem Dancer. Gaston Guedy

"In simplest terms, an odalisque was a female slave in a harem, trained to serve her master's pleasure, and assigned to sexual rather than domestic duties. In practice, not all odalisques were sexual partners of their owners, but they were trained and owned with this purpose in mind. Younger odalisques also served as companions and attendants of older women, in a similar way to the aristocratic ladies-in-waiting of a queen in western monarchies."Odalisques.com
I have always been fascinated by this concept, and so here I shall collect my various posts on the subject. If you want to participate, post the links to your own Odalisque posts below.
