The painters of the Barbizon School were really interested in landscape painting; they wanted to depict nature directly, outside of the classical conventions. That's why you'll see so many landscapes in a similar style on that wall.
I do love Fontainebleau.
Many of the Barbizon school painters worked in the Forest of Fontainebleau, just outside of Paris, as nature, rather than urban life, provided inspiration for their works. They got their name from the nearby village of Barbizon.
