"This scene is set in the Stabian Baths of Pompeii. In the foreground one woman playfully splashes another in the 'frigidarium,' a cold bath. The artist based this work on photographs of the remains of the baths, revealed by archaeologists in 1824. He has made them more luxurious by adding a marble floor and walls which have usually been found in larger imperial baths. The Dutch-born artist Alma-Tadema achieved enormous success in Britain with carefully researched scenes like this of daily life in the ancient Roman world."
Well, I suspected as much. I wonder if anyone else is interested. Anyway, Eureka!
