This is a print I've had for a long time, but had no identifying information. I surmised that this is Helen, she of Troy, based on the hub-bub outside the window. And sure enough, 'tis so. Finding her in a book that I've since lost track of, as well as the author (maybe Bettany Hughes?), this is the caption:
This image, painted in 1914, is what Helen has become: not a part of the Eastern Mediterranean but distinct from it, a white woman attended to by an oriental slave. A vain and shallow creature, lost in her own image while behind her Troy burns.
I still can't identify the artist for now.
