American Painting and its Tradition by John C. Van Dyke

During the Revolutionary Period, and immediately thereafter, art in America was something of sporadic growth, something not quite indigenous but rather transplanted from England. Painting was little more than portraiture, and the work was done after the English formula. America had no formula of its own. There was no native school of art, no tradition of the craft, no body of art knowledge handed down from one generation to another. West and Copley started out practically without predecessors. They were the beginners.

With Cole, Durand, and, later on, Kensett, that is about 1825, another kind of painting sprang up on American soil. It was the painting of landscape -- landscape of the Hudson River variety -- and, whatever its technical shortcomings, at least it had the merit of being original. Apparently nothing of artistic faith or of accumulated knowledge or art usage was handed down to the Hudson River men by the portrait-painters who had preceded them. The leaders worked from nature with little or no instruction. They were self-taught, and if any inkling of how work was carried on in the painting-rooms of Copley, Stuart, or Vanderlyn was given them, they turned a deaf ear to it or found it inapplicable to their landscape-work. If they knew of a tradition they ignored it.
