In 1793, when he was going through financial difficulties, he brought together under the title of Ouvrage priapique a series of prints he had engraved during the previous ten years.
His works are mainly inspired by scenes observed on the ancient vases or on the walls of the walls of Herculaneum during his long stays in Italy, Naples and Venice.
These libertine and scabrous pieces are as burlesque and grotesque as they are erotic.
This publication was probably never openly marketed: such licentious prints could have brought him serious trouble in the context of the terror.
