It was a big, round room with a high arched roof, and the walls and ceiling and floor were covered with large emeralds set closely together. In the center of the roof was a great light, as bright as the sun, which made the emeralds sparkle in a wonderful manner.

But what interested Dorothy most was the big throne of green marble that stood in the middle of the room. It was shaped like a chair and sparkled with gems, as did everything else. In the center of the chair was an enormous Head, without a body to support it or any arms or legs whatever. There was no hair upon this head, but it had eyes and a nose and mouth, and was much bigger than the head of the biggest giant.

As Dorothy gazed upon this in wonder and fear, the eyes turned slowly and looked at her sharply and steadily.
