7. Daubigny, "The Banks of the Oise River," 1863

After his first venture on his studio boat, Daubigny embarked on more painting trips—often for weeks at a time—in spring, summer, and fall. The pictures created on his boat trips have a watery foreground that features reflections of the sky, clouds, and trees. No one had ever painted landscapes like this; he had invented another new compositional type that everyone recognized then as highly original.
