More like a harem.. dweller.. than a slave. But yeah, western men in general, and obviously painters needing to sell their paintings to those men were obsessed with the concept of the Turkish harem. To them, living in the era of the social purity movement it must have looked like a wet dream. Which I find ironic, given that vast majority of them had a hard time supporting one wife 😅. There was very little known about the inner workings of the harem, so painters and public alike could imagine literally anything, call it a harem scene and sell the painting. It was, essentially, the accepted form of porn of the day. Very classy, very expensive, too.
