At the age of forty-one, Henri Rousseau gave up his work as a customs official to devote himself entirely to painting. A self-taught artist, he developed a style characterised by distortions and unnatural proportions and perspectives. Tiny human figures promenade along an avenue lined with rows of uniform trees. In naïve manner, every detail – whether in the foreground or background – is treated equally. Rousseau is considered a precursor of Surrealism because of the way dream worlds and reality merge in his works.
