 
The 120 Days of Sodom or the School of Licentiousness (Les 
120 journées de Sodome ou l'école du libertinage) is a book written by the 
French writer Donatien Alphonse François, Marquis de Sade in 1785. It relates 
the story of four wealthy men who enslave 46 mostly teenaged victims and 
sexually torture and kill them while listening to stories told by old 
prostitutes.
The book was not published until 1905. Originally written in French, it was 
translated into many languages, including English, Japanese and German. Due to 
its extreme sexual and violent nature, the book remained banned in many 
countries for a long time.
