The Decadent movement was a late-19th-century artistic and literary movement, centered in Western Europe, that followed an aesthetic ideology of excess and artificiality. The visual artist Félicien Rops's body of work and Joris-Karl Huysmans's novel Against Nature (1884) are considered the prime examples of the decadent movement. It first flourished in France and then spread throughout Europe and to the United States. The movement was characterized by a belief in the superiority of human creativity and pleasure over logic and the natural world.
