Victorian painters of medieval themes are often referred to as pre-Raphaelite, following an artistic style thought to have existed prior to the Renaissance.
Various 19th Century renditions of “The Birth of Venus” make Lady Godiva look like a prude, especially as done by French painters.
The PRB is a specific small group, the leader of which was Dante Gabriel Rossetti, and he was evocative in his works, but probably the least talented in the technical sense. Lord Leighton (one of the artists of those two blam posted) wasn’t, I don’t thing Waterhouse (the other artist up there) was either. Alma-Tadema, who with Leighton had a similar talent for both stunningly realistic scenes and prolific output, is probably my favorite (he did a lot of scenes imagined from classical antiquity).
