HISTORY OF ARCHITECTURE FUN FACT!!! PANTHEON - the largest dome ever built in masonry or unreinforced concrete. "T H E E Y E" The Pantheon has no windows and the only light penetrates from above streaming down like a river of inner light; towards midday, the rays coming through the Oculus (the Latin word for “eye”) are particularly intense. A beam of light penetrates this circular hole to create a dramatic effect as it slowly travels across the floor and wall of the rotunda, illuminating them like a spotlight. This intriguing aspect of the Pantheon immediately catches the eye of any visitor who enters the vast circular space.
