The Dome That Was Never Built
A flat ceiling opens into a convincing dome, entirely through paint.

A short colonnade looks like a much longer passage.
Compare the front and rear columns. Notice the rising floor and imagine an adult standing beside the statue at the far end.

Compare the front and rear columns. Notice the rising floor and imagine an adult standing beside the statue at the far end.
The columns become smaller, the walls converge and the floor rises towards the end. These physical changes exaggerate the normal perspective of a long corridor. The distant statue offers a misleading sense of scale. A person inside the passage would reveal how compressed it is.
