Sous-bois (or undergrowth) emerged as a sub-genre of landscape painting in 19th-century French art, typically in the form of a study of tree trunks and the forest floor, or trees with a solitary figure. This exhibition catalogue explores Van Gogh’s contributions through 30 paintings by the artist and his contemporaries and precursors, including Corot, Gauguin and Cézanne. Accompanying essays examine the Barbizon School, Van Gogh’s nature painting and his 1890 canvas, Undergrowth with Two Figures.
