Marquis de Sade (1740-1814), born Donatien Alphonse François de Sade, was a French aristocrat, novelist, dramatist, and political prisoner whose name became inseparable from libertine literature, sexual transgression, censorship, and the philosophical extremes of Enlightenment thought. His works examine desire, power, cruelty, hypocrisy, religious authority, social control, and the collision between private appetite and public morality. Long suppressed, condemned, and circulated in restricted forms, Sade's fiction has become central to the study of eighteenth-century French literature, erotic literature, Gothic and libertine fiction, and the history of banned books.Sade's major works include Justine, Juliette, The 120 Days of Sodom, Philosophy in the Bedroom, and the stories collected in Les Crimes de l'amour. While his most notorious books are often remembered for their extremity, his shorter fiction also reveals a writer deeply interested in confession, reversal, fatalism, and moral ambiguity. Florville and Courval shows Sade working in a concentrated narrative form, combining erotic scandal, psychological disclosure, and a grimly ironic vision of fate.
