Thérèse Philosophe (Therese the Philosopher) is a 1748 French novel ascribed to Jean-Baptiste de Boyer, Marquis d’Argens, or, according to a minority opinion, Denis Diderot and others.
It has been chiefly regarded as a pornographic novel, which accounts for its massive sales in 18th-century France. 

For all of its printed debauchery, the work has some philosophical merit in its underlying concepts. Between the more graphically adult sections of the novel, philosophical issues would be discussed amongst the characters, including materialism, hedonism and atheism. All phenomena are matter in motion, and religion is a fraud, though useful for keeping the working classes in line.

The book not only draws attention to the sexual repression of women at the time of the enlightenment, but also to the exploitation of religious authority through salacious acts. _Wikipedia

I did some research to find various artworks by different artists, all for the same story. There aren’t many artists known, while there are various editions of the book with different artworks.
Antoine Borel was the artist who illustrated for the edition published in 1785. There are also some artworks done by an artist or engraver named Delchroche (for who I was unable to find info)._{Vintage Bdsm Art}
