@PUNKEY,
A quotation from "Sherlock Holmes and the King’s Evil" by Donald Thomas:
Quote:For some time Howell lived as man and wife with a woman in Bond Street, Rosa Corder. By profession she was a painter of horses and dogs. He trained her as what he called a facsimilist-in plain English, a forger. Between them they also produced copies of pictures for clients of questionable tastes. Some rather objectionable paintings by Fuseli were copied for sale, which was the cause of their landlord giving them notice.
Below is a painting by John Henry Fuseli (1741 - 1825) called "The Nightmare". To "respectable" Victorian English people it would have been shockingly explicit and disturbing. The shape of the woman's body is clearly shown, and the ugly monster sitting on her probably intends to have sex with her. Or maybe already has.
