The world of art offers rich applications of mathematics, and one of the most important of these applications is the notion of perspective. If an object is drawn in perspective, it is drawn as the eye sees it. We know, for example, that the height and width of the front face of the cube in figure 1 are the same as those of the back face. To the eye, however, the sides of the front face appear to be considerably longer than those of the back face. Moreover, the top, side, and bottom faces of the cube do not even appear to be squares.
