Vincent in Paris
(Spring 1887)
 

The woodland scene genre, or "sous-bois" in French for undergrowth, was popular with artists from the Barbizon School and Impressionists.
Rather than painting landscapes from afar like traditional painters, 19th-century rural painters climbed or walked into forested areas for a close view of wooded scenes. Paintings of the sous-bois, evoking the trees and grassy undergrowth, were often made vertically on canvas, as opposed to horizontal views of sweeping landscapes. In a sous-bois, the sky is barely visible, just a glimpse of sky sometimes penetrating the branches. This type of composition was rare before the 19th century when artists of the Barbizon School made paintings of forested areas in the Fontainebleau region of France. Close to the subject of the painting, artists painting sous-bois capture their experience in the forested scene. In German, the painting of interior forests was called Waldinneres, meaning enclosed woodland space.
