Sortie de forêt à Fontainebleau, soleil couchant

Sortie de forêt à Fontainebleau, soleil couchant (Leaving the Fontainebleau Forest at Sunset), painted in 1848 and now in the Louvre, is considered one of Rousseau's masterpieces and a defining statement of the Barbizon school's ambitions for landscape painting. The forest edge at sunset — the moment of transition between the enclosed world of the trees and the open expanse of the plain — gave Rousseau a compositional opportunity to explore both his primary landscape domains simultaneously. The sunset light transforms the forest margin from a simple topographical boundary into a scene of extraordinary chromatic drama: the sky is burning, the tree silhouettes are dark against it, and the plain catches the last warm reflections of a descending sun. Rousseau had been building toward this image across years of direct study of the Fontainebleau forest and surrounding plain, and the 1848 canvas synthesises that accumulated knowledge into a composition of great formal ambition. Its entry into the Louvre's collection confirmed Rousseau's status as the central figure of French Romantic landscape.

The painting is structured around the silhouetted forest edge — trees rendered as dark, complex masses against a brilliant warm sky. The sunset palette exploits the full range from deep orange-red at the horizon to pale gold above, with the open plain catching warm reflected light below. Rousseau used thick impasto in the most intensely lit sky zones.
