The walls of this wide passage are made of close-fitting sandstone

blocks, each as long as a human is tall, and half as thick. The floor

is lined with rectangular tiles, the cracks between them filled with

dust and sand. The atmosphere in the pyramid is one of claustrophobic

malevolence, as if evil creatures were lurking at every turn, and the

pyramid itself were a hateful entity. A rectangular shaft is set in

the floor here, with an identical one in the ceiling above it.
