Light is the Sculptor of Space It is not surprising that often architects emphasise that their work revolves around light, just as some painters have focused completely on color. The perpetual spirit and metaphysical strength of architecture are driven by the quality of light and shadow, shaped by solids and voids, by opacities, transparencies, and translucencies. Appropriately termed as the 'Fourth dimension', light is what brings to the fore front, space defined by length, breadth and height.
