John Marin (1872-1953) The year John Marin painted Tree, Castorland, was seminal in the development of American Art. The 1913 Armory Show exposed the broader American public to the avant-garde art of Europeans Georges Braque, Marcel Duchamp, Wassily Kandinsky and Henri Matisse; as well as Americans Oscar Bluemner, Marsden Hartley and John Marin for the first time. The Armory Show set the course of 20th century art in America and created a market for works by Modernist painters. In Tree, Castorland, Marin combines vibrant fauve-inspired colors with a deep love of nature, particularly trees. Marin felt trees had a deeply spiritual quality to them, and trees are central to Marin’s work in the same way that Maine and New York City are.
