" The rooftops of a great city present a panorama unlike anything else in the world. A range of giant gumdrop karst formations may impress, a deep canyon awe, a jungle canopy stun into silence, but cities alone are the product of human hands and human tools, human blood and human will. They come into being with worship, or not at all. "
