Delville was a Belgian writer and painter, and an initiate of the occult. His work "Dialogue among Ourselves, Cabbalistic, Occult, and Idealist Arguments" is well known in the Pagan community. He was one of the founders of the" Cercle pour l'Art", and he also founded the "Salon d'Art Idéaliste". Delville's work reveals the idealist and esoteric currents which typified an era in which secretive obsessions were constantly at work.
