The dark eunuch was held as the embodiment of the sensual tyranny that held sway in the fantasized Ottoman palace, for he had been "clipped" or "completely sheared" to make of him the "ultimate slave" for the supreme ruler. In the Ottoman court, white eunuchs, who were mostly brought from castration centers in Christian Europe and Circassia, were responsible for much of the palace administration, while black eunuchs, who had undergone a more radical form of castration, were the only male slaves employed in the royal harem.
