À rebours
Huysmans' work is considered remarkable for its idiosyncratic use of the French language, large vocabulary, descriptions, satirical wit and far-ranging erudition. First considered part of Naturalism, he became associated with the decadent movement with his publication of "À rebours." His work expressed his deep pessimism, which had led him to the philosophy of Arthur Schopenhauer. In later years, his novels reflected his study of Catholicism, religious conversion, and becoming an oblate. He discussed the iconography of Christian architecture at length in "La cathédrale" (1898), set at Chartres and with its cathedral as the focus of the book.
