À rebours
In his 1884 decadent novel "À rebours" (English: "Against Nature" or "Against the Grain"), Joris-Karl Huysmans identified likely candidates for the core of the Decadent movement, which he seemed to view Baudelaire as sitting above: Paul Verlaine, Tristan Corbière, Theodore Hannon and Stéphane Mallarmé. His character Des Esseintes hailed these writers for their creativity and their craftsmanship, suggesting that they filled him with "insidious delight" as they used a "secret language" to explore "twisted and precious ideas."
