By the 1740s, colonial America had matured to the point where its increasing wealth allowed grander expressions of architecture than the saltboxes and other basic subsistence forms that a rough frontier life dictated. The English colonialists naturally turned to their homeland for inspiration and drew on the latest styles there. What they borrowed was a mix of classical themes that the English had drawn from the Italian Renaissance, primarily from the work of Palladio. The most famous manifestation of these phenomena is probably Thomas Jefferson’s home, Monticello.
