Sometimes a tomb was more pretentious than those above described. There is an edifice at Meydoum, improperly termed a pyramid, which is thought to be older than Sneferu, and was probably erected by one of the "shadowy kings" who preceded him on the throne. Situated on a natural rocky knoll of some considerable height, it rises in three stages at an angle of 74° 10' to an elevation of a hundred and twenty-five feet. It is built of a compact limestone, which must have been brought from some distance. The first stage has a height a little short of seventy feet; the next exceeds thirty-two feet; the third is a little over twenty-two feet. It is possible that originally there were more stages, and probable that the present highest stage has in part crumbled away; so that we may fairly reckon the original height to have been between a hundred and forty and a hundred and fifty feet The monument is generally regarded as a tomb, from its situation in the Memphian necropolis and its remote resemblance to the pyramids; but as yet it has not been penetrated, and consequently has not been proved to have been sepulchral.
