“Art, or the graphic transition of a culture, is shaped by the way space is perceived. Since the Renaissance the Western artist perceived his environment primarily in terms of the visual. Everything was dominated by the eye of the beholder. His conception of space was in terms of a perspective projection upon a plane surface consisting of formal units of spatial measurement. he accepted the dominance of the vertical and the horizontal—of symmetry—as an absolute condition of order. This view is deeply embedded in the consciousness of Western art.”
