"Respecting the mighty works of Egypt, little mystery remains. The great Pyramids had been rifled by the Caliphs, if not by earlier hands, and no inscriptions have been found. But no doubt exists that they were the sepulchres of the Kings of Memphis. The Queens and the "princes of Noph" reposed in smaller pyramids beside the Kings. These mountains of wasted masonry belong to the earliest ages of the Pharaonic monarchy, before the time of the Sesostrian conquests, and therefore they bespeak the toil and suffering, not of captives, but of native slaves. Before them couches the Sphinx, hewn from the rock, to spare, as a Greek inscription says, each spot of cultivable land. His riddle--for it is _a male_--is read. He represents, perhaps portrays, the reigning King, and the thick lips may indicate Ethiopian blood. The lion's body represents the monarch's might--the human head his wisdom. The rock, from which the figure is cut, broke the view of the Pyramids, and to convert it into the Sphinx was a stroke of Egyptian genius. Pyramids were, in the Pharaonic times, peculiar to Memphis. The countless tombs of Thebes are excavated in the rocky face of the Libyan hills. Those of the Theban Pharaohs stand apart, and we approach through a narrow gorge called the "Gate of Kings." The paintings, sculptures, and inscriptions on these tombs, literally the eternal _houses_ of the dead, are the Pompeii of the Egyptian antiquary. At Thebes are the magnificent and temple-like palaces of the greatest of the Pharaohs, the halls of their assemblies and their counsels, the records of their wars and conquests. At Thebes, too, is the Memnon, a mutilated statue of Amnoph, which never was vocal except by trick or in imagination, and the Obelisks, whose form is sufficiently explained, without obscenity or mystery, by the fancy for monolithic monuments and the possession of large blocks of granite. The remains of the Labyrinth do not enable us to pronounce whether its twenty-seven halls were a burial-place for kings or crocodiles, or a place of assembly for the provinces of Egypt. "Very various and very extravagant notions have been formed of the population of ancient Egypt. That it was dense may well be inferred from the length of time through which it multiplied in a limited space, and from that evident parsimony of land which drove tombs and monuments to the rocks, and cities to the edge of the desert. Calculations based on the number of cities, and on the number of men of military age, have plausibly placed the sum at about five millions.
