The staircase, which was of stone, still remained, however, leading to four galleries, also of stone.

Perhaps once there were floors as well, but if so these had vanished, only the stone galleries and their balustrades remaining.
Ithiel led Nehushta up the stair, which, though narrow, was safe and easy.

Resting at each story, at length they came to that gallery which projected from its sides within ten feet of the top of the tower, and saw Jerusalem and the country round spread like a map beneath.

Then, as it was sunset, they returned.

At the foot of the stair Ithiel gave Nehushta the piece of iron and showed her how to lift the secret latch and pull upon the block of hewn stone that was a door, so that it opened to swing to again behind them.
Next morning, before it was dawn in the world above, Miriam aroused Nehushta.
