There are several landscapes that imply man's dominance over, or submission to, nature by the simple device of relative size. But more interesting is Ubaldo Bartolini, who conjures up an idealized myth of nature in dreamlike paintings based not upon nature, but on earlier landscapes by Nicolas Poussin and Claude Lorrain. Intended or not, they also have in them a good deal of the Romantic, visionary spirit of 19th-century American landscapes.
