The necropolis quarter of Abydos, in which were interred the earlier generations of the Theban Empire, furnishes the most ancient examples of the first system. The tombs are built of large, black, unbaked bricks, made without any mixture of straw or grit. The lower part is a mastaba with a square or oblong rectangular base, the greatest length of the latter being sometimes forty or fifty feet. The walls are perpendicular, and are seldom high enough for a man to stand upright inside the tomb. On this kind of pedestal was erected a pointed pyramid of from 12 to 30 feet in height, covered externally with a smooth coat of clay painted white. The defective nature of the rock below forbade the excavation of the sepulchral chamber; there was no resource, therefore, except to hide it in the brickwork. An oven- shaped chamber with "corbel" vault was constructed in the centre (fig. 144); but more frequently the sepulchral chamber is found to be half above ground in the mastaba and half sunk in the foundations, the vaulted space above being left only to relieve the weight (fig. 145).
The earliest examples of the second kind are those found at Gizeh among the mastabas of the Fourth Dynasty, and these are neither large nor much ornamented. They begin to be carefully wrought about the time of the Sixth Dynasty, and in certain distant places, as at Bersheh, Sheîkh Saîd, Kasr es Saîd, Asûan, and Negadeh.
In these rock-cut tombs we find all the various parts of the mastaba. The designer selected a prominent vein of limestone, high enough in the cliff side to risk nothing from the gradual rising of the soil, and yet low enough for the funeral procession to reach it without difficulty. The feudal lords of Minieh slept at Beni Hasan; those of Khmûnû at Bersheh; those of Siût and Elephantine at Siût and in the cliff opposite Asûan (fig. 150). Sometimes, as at Siût, Bersheh, and Thebes, the tombs are excavated at various levels; sometimes, as at Beni Hasan, they follow the line of the stratum, and are ranged in nearly horizontal terraces.[][31]] A flight of steps, rudely constructed in rough-hewn stones, leads up from the plain to the entrance of the tomb. At Beni Hasan and Thebes, these steps are either destroyed or buried in sand; but recent excavations have brought to light a well- preserved example leading up to a tomb at Asûan.[][32]]
The funeral procession, having slowly scaled the cliff-side, halted for a moment at the entrance to the chapel. The plan was not necessarily uniform throughout any one group of tombs. Several of the Beni Hasan tombs have porticoes, the pillars, bases, and entablatures being all cut in the rock; those of Ameni and Khnûmhotep have porticoes supported on two polygonal columns (fig. 151). At Asûan (fig. 152), the doorway forms a high and narrow recess cut in the rock wall, but is divided, at about one- third of its height, by a rectangular lintel, thus making a smaller doorway in the doorway itself. At Siût, the tomb of Hapizefa was entered by a true porch about twenty-four feet in height, with a "vaulted" roof elegantly sculptured and painted.
