Odilon Redon (1840-1916) : Unclassifiable French painter. Closest to Henri Rousseau; both seemed to work in the dreamworld, except that Redon's art was less sharp-edged in style. He worked first in prints and then later in pastels and oils; first obsessed with darkness, later luminous. Many emotions run through his work, but longing seems to be a key (see his painting, The Cyclops). His work prefigured both surrealism and Marc Chagall's.
