Odilon Redon (1840–1916) spent the first half of his career making charcoal drawings and lithographs filled with extraordinary darkness: floating eyeballs, severed heads with aureoles, creatures with the body of a fish and the head of a man. In the second half, he made pastels of almost unbearable luminosity, with fields of flowers in colors that seemed to come from somewhere outside the visible spectrum. In both cases, he was trying to portray the world that lies just beyond what the eye can actually see. The Getty Center is presenting a focused selection of Redon works from its own collection. The show includes charcoals, lithographs, and pastels drawn from religion, mythology, literature, and modern science. —Elena Clavarino
