Charles-Marie-Georges Huysmans (February 5, 1848 – May 12, 1907) was a French novelist who published his works as Joris-Karl Huysmans. He is most famous for the novel À Rebours (Against the Grain or Against Nature), a representative work of Parisian decadence that heavily influenced British aesthetes like Oscar Wilde and Aubrey Beardsley. Such books in Paris were wrapped in yellow paper to alert the reader to their lascivious content.
In Oscar Wilde's The Picture of Dorian Gray (1891), a major corrupting influence on Dorian is "the yellow book" which Lord Henry sends over to amuse him after the suicide of his first love. This "yellow book" is understood by critics to be À Rebours.
