[181] The existence of the passage leading to the mummy chamber was not unknown to Strabo. He says: "Very nearly at the middle of their sides, as to height, the pyramids had a stone which could be moved away; when this is done, a winding passage appears, which leads to the coffin" (xvii. p. 1161, C).

[182] This pyramid was opened on February 28, 1881. Circumstantial accounts of the discoveries to which it led have not yet been published. The Moniteur Égyptien of March 15, 1881, contains a short account of the opening. [Since this note was written, a full account of the entrance and exploration of this pyramid, together with the texts discovered, has been published by M. Maspero in the Recueil de Travaux, vol. iii. liv. 3 and 4, 1882.—Ed.]

[185] The base of the great pyramid at Sakkarah is a rectangle, measuring 390 feet from north to south, and 347 from east to west. The three great pyramids at Gizeh like most of these structures, are built upon a base which is practically square.

[187] This method of construction may be easily recognized in the Pyramid of Meidoum. That curious structure was built in concentric layers round a nucleus. These layers are by no means equal in the excellence either of the workmanship or of the materials employed. Some show supreme negligence; in others we find the builders of the Ancient Empire and their materials both at their best. The same fact has been observed in regard to the Stepped Pyramid and the pyramids at Abousir. It would seem that the work was assigned in sections to different corvées, whose consciences varied greatly in elasticity. (Mariette, Voyage de la Haute-Égypte, p. 45.)
