As he looked, the edge of the moon rose above the temple wall, and by slow degrees a wonderful sight was revealed to him.

Not till the moon was fully visible did he see everything, and to describe all as he discovered it, piecemeal, would be difficult.

This was what Leonard saw at length.
Before him and underneath him lay a vast and roofless building, open to the east, covering some two acres of ground, and surrounded by Titanic walls, fifty feet or more in height.

This building was shaped like a Roman amphitheatre, but, with the exception of the space immediately below him, its area was filled with stone seats, and round its wide circumference stone seats rose tier on tier.

These were all occupied by men and women in hundreds, and, except at the further end, scarcely a place was empty.
