In "Oblique Drawing," Massimo Scolari investigates "anti-perspective" visual representation over two thousand years, finding in the course of his investigation that visual and conceptual representations are manifestations of the ideological and philosophical orientations of different cultures. Images prove to be not just a form of art but a form of thought, a projection of a way of life. Scolari's generously illustrated studies show that illusionistic perspective is not the only, or even the best, representation of objects in history; parallel projection, for example, preserves in scale the actual measurements of objects it represents, avoiding the distortions of one-point perspective.
