This system of pyramid building would explain the curious shapes which we have noticed in the Stepped Pyramid and the southern pyramid of Dashour.[193] Both of those erections would thus be unfinished pyramids. At Sakkarah, the angles left by the successive stages would be waiting for their filling in; at Dashour, the upper part of a pyramid of gentle slope would have been constructed upon the nucleus which was first erected, but the continuation of the slope to the ground would have been prevented by the stoppage of the works at the point of intersection of the upper pyramid and its provisional substructure. Hence the broken slope which has such a strange effect, an effect which could not have entered into the original calculations of the architect. [193] There are other stepped pyramids besides that at Sakkarah. Jomard describes one of crude and much crumbled brick at Dashour. It is, he says, about 140 feet high. Its height is divided into five stages, each being set back about 11 feet behind the one below. These steps are often found, he adds, among the southern pyramids, and there is one example of such construction at Gizeh. (_Description de l'Égypte_, vol. x., p. 5.) At Matarieh, between Sakkarah and Meidoum, there is a pyramid with a double slope like that at Dashour. But although this theory seems satisfactorily to explain some puzzling appearances, it also, when tested by facts, encounters some very grave objections. The explorers of the pyramids have more than once, in their search for lost galleries and hidden chambers, cut for themselves a passage through the masonry, but neither in these breaches made by violence, nor in the ancient and carefully constructed passages to which they were the means of giving access, have any signs been, discovered, or at least, reported, of the junctions of different surfaces and slopes which must have existed according to the theory which we are noticing. We should expect, at least, to find the nearly upright sides of the cubic mass with which the pyramid began, contrasting with the comparatively gentle slopes which were built against it. These different parts of the pyramid, we are told, were built and finished separately, a proceeding which, if the later parts were to be properly fitted to the earlier and the final stability of the monument assured, would have demanded a minute and scrupulous care which was not common with Egyptian workmen. How, without numerous through bonding-stones, could those slides and settlements be prevented to which the want of homogeneity in the structure would otherwise be sure to lead? But we are not told that any such junctions of old and new work are to be found even in those points where they would be most conspicuous, namely, in the galleries leading to the internal chambers, where a practised eye could hardly fail to note the transition. We do not say that there are no such
