Monsieur de Phocas (1901) has been ranked with Huysmans' À Rebours (1884) as the summation of the French Decadent Movement. In the novel, Jean Lorrain presents experiences of the darker side of his life in Paris as the adventures of the Duc de Freneuse (Phocas) and his relationship with the svengaliesque English painter Claudius Ethal

This book ranks with 'A Rebours' as the summation of the French Decadent Movement. Modelled on 'The Portrait of Dorian Gray, ' it drips with evil and certainly would have been unpublishable in fin de siecle England.

“The madness of the eyes is the lure of the abyss. Sirens lurk in the dark depths of the pupils as they lurk at the bottom of the sea, that I know for sure - but I have never encountered them, and I am searching still for the profound and plaintive gazes in whose depths I might be able, like Hamlet redeemed, to drown the Ophelia of my desire.”
― Jean Lorrain, Monsieur De Phocas
