COFFERED DOME
Pantheon
Rome
c. 118-128
The coffered dome rises to a twenty-seven foot circular opening called the oculus. It is the one light source for the interior. In five steps, and recessed four times, the coffering diminishes in size. This lightens the load on the dome and enhances its appearance of height. Originally the coffers were decorated, possibly with gold stars against a blue background.
