I’ve got a book on some of the “forbidden art” from Pompeii.
EROS IN POMPEII.
Rather interesting!
Probably not a lot different than today’s private selfies. Except for being painted on the wall where everyone could see them. There were a number of small brothels where pictures were collected, and one larger one (10 rooms). Other than that, the pictures seemed to be on private bedroom walls. And some of the images implying delusions of grandeur were on the front of the house as images of abundance rather than sexuality. Most that I saw were of execrable quality. Obviously brothels didn’t have a large profit margin to hire the better artists. There was one exquisite mosaic from a mansion but, other than that, not impressive art.
