An apostle of perversity and decadence, author of A rebours (Against the Grain) (1884) and La-Bas (Down There) (1891). His 1884 cult novel titled: "A rebours (Against Nature)" was a story that featured a decadent aristocrat who collected the drawings of a then relatively obscure artist named Odilon Redon. La-Bas concerns itself with the then-novel subject of Satanism.
In later years he became a devout Catholic.
