temples, and so under the guardianship of their venerated religion. As for the other parts of the tomb, a little attention will always suffice for their identification even in those sepulchres which differ most from the mastaba. In some instances we shall find the mummy chamber contrived in the upper structure, in others the whole tomb is cut in the living rock. Sometimes we find the chapel, as we may call the public chamber in which the miraculous nourishment of the _double_ took place, more or less distantly separated from the mummy chamber; sometimes the well almost disappears, sometimes it ceases to be vertical and becomes a long corridor with but a gentle slope. As a rule all these variations are easily explained, and may be connected without difficulty with that primitive type which we have attempted to define by its most wide-spread and constant features. [Illustration: FIG. 126.--Head of a Mummy. Louvre.] Another method of sepulture was made use of in the Ancient Empire, a method which afterwards came into general use in Egypt, we mean the _hypogeum_, or subterranean tomb. The Egyptian Commission has described several rock-cut tombs in the neighbourhood of the Pyramids, especially some which face the western slope of the Second Pyramid. Similar tombs are to be found near the pyramid of Mycerinus. Some of these sepulchral grottos declare their extreme antiquity by their imitations of wooden architecture;[174] others by their inscriptions dating from the fourth and fifth dynasties. We shall not dwell long upon these rock-cut tombs. They are generally composed of one or two small sculptured chambers, upon one of which the well opens which leads to the mummy chamber. We shall postpone their study to a later chapter, as the time of the Middle Empire affords us richer and more complete examples of them than the earlier period; but, indeed, the New Empire has left us the most important examples of this kind of sepulchre. We shall here content ourselves with pointing out that the architects of Memphis did not ignore the facilities offered by the easily cut limestone rocks, not only for construction of well and mummy chamber, but also for those open parts of the tomb where the funeral rites and the ceremonies of the Ritual of the Dead were performed. In the whole course of her long vitality Egypt did little more, either in art or religion, than develop, with variations, the themes presented to her by the generations which were ruled by her first six dynasties.
