The oak tree crashed into the forest of Fontainebleau 

Theodore Rousseau, a prominent figure in the Barbizon School, captured the essence of the French countryside in this charcoal drawing. His focus on natural light and atmospheric effects is evident in the subtle shading and the interplay of light and shadow on the dense foliage. The "oak tree" in the foreground is a testament to the artist's fascination with the gnarled forms and textures of nature. Rousseau's works, known for their realistic depictions of landscapes, paved the way for later Impressionist and Realist artists.
