The blocks are small and badly cut, and the courses are concave, according to a plan applied both to quays and to fortresses.

On examining the breaches in the masonry, it is seen that the outer face of each step is coated with two layers, each of which has its regular casing (Note 32).

The mass is solid, the chambers being cut in the rock below the pyramid.

It has four entrances, the main one being in the north; and the passages form a perfect labyrinth, which it is perilous to enter.

Porticoes with columns, galleries, and chambers, all end in a kind of pit, in the bottom of which a hiding place was contrived, doubtless intended to contain the most precious objects of the funeral furniture.
The pyramids which surround this extraordinary monument have been nearly all built on one plan, and only differ in their proportions.
