The one I'm interested in has three women at a public bath with large pools. The lower part has the women, the men are in the back, but there isn't a proper separation. Indeed, one of the men is belly down on the marble border of the pool, trying to reach down, the lecher. The woman in the middle has sandals and a flowing vest. There's huge cylindical columns in some dark brown stone, with white corinthyan capitals and friezes. Lots of people, but most on the background. Portrait orientation.
Orientalism. Vibrant colours. Probably oil on canvas?
