Henri Rousseau (also called Le Douanier), 1844-1910, French painter. He was entirely self-taught, and his work remained consistently naive and imaginative. The only tropical vegetation Rousseau ever saw was in Parisian greenhouses, and his remarkable landscapes had no counterpart in nature. His painted jungles are an organized profusion of carefully defined yet fantastic plants, half-concealing various wild animals with startlingly staring eyes. These scenes are rendered in a vivid, almost hypnotic folk style. The finest ones include The Snake Charmer (1907; Louvre) and The Dream (1910; MOMA). In his fantastic Sleeping Gypsy (1897; MOMA), a gispy sleeps in a nighttime desert, closely observed by a lion—the entire absurdity rendered in a compelling, straightforward manner. The painting thus combines the unique elements of Rousseau's art to their most startling effect. Rousseau exhibited at the Salon des Indépendants from 1886.
