J lo A History of Art in Ancient Egypt. private individuals also. Throughout the existence of the Egyptian monarchy the inhabitants of the Delta were obliged to set about the preservation of their dead in a different fashion to that followed by their neighbours in Upper Egypt ; their mummies had to be kept out of reach of the inundation. Isolated monuments, like those of Abydos, would soon have filled all the available space upon artificial mounds, such as those upon which the cities of the Delta were built. The problem to be solved was, however, a simple one. Since there could be no question of a lateral development, like that of the Theban tombs, or of a down- ward one, like that of the Memphite mummy pits, it was obvious that the development must be upwards. A beginning was made by constructing, at some distance from a town, a platform of crude brick, upon which, after its surface had been raised above the level of the highest floods, the mummies were placed in small chambers closely packed one against another. As soon as the whole platform was occupied, another layer of chambers was commenced above it. Champollion discovered the remains of two such cemeteries in the immediate neiofhbourhood of Sais. The larger of the two was not less than 1,400 feet long, 500 feet wide, and 80 feet high ; an enormous mass " which resembled," he said, "a huge rock torn by lightning or earthquake."^ No doubt was possible as to the character of the mass ; Champollion found among the debris both canopic vases and funerary statuettes. Within a few years of his death Mariette undertook some fresh excavations in the same neighbourhood ; they led to no very important results, but they confirmed the justice of the views enunciated by Champollion. Most of the objects recovered were in a very bad state of preservation ; the materials had been too soft, and in time the dampness, which had impregnated the base of the whole structure, had crept upwards through the porous brick, and turned the whole mass into a gigantic sponge. These tombs resemble those of the kinofs in havinsf no well ; and as for the funerary chapel we do not as yet know whether it existed at all, how it was arranged, or what took its place. Perhaps each of the more carefully constructed tombs was divided into two parts, a chamber more or less decorated and a niche contrived in the masonry, like the rock-cut ovens of the Phoenician catacombs.
