In its darkness and abstraction, Redon's work remains exceptionally relevant today: his spiders, floating heads and glowing conch shells in near-empty frames could easily be contemporary. His figures and objects from the worlds of antiquity, Christianity and nature are often veiled in iridescent clouds of color, to enigmatic and mystical effect. In charcoal drawings and lithographs, Redon devoted himself to the human subconscious, with its fears and nightmares, and produced an urgent and eerie Symbolist oeuvre. This substantial retrospective underlines his central importance for an emergent Modernism. Redon is credited not just with changing the course of Impressionism, but with influencing artists as disparate as Duchamp, the Surrealists and Jasper Johns.
