The annexed plan and section of Sakkara (Woodcut Nos. [9] and [10]), both to the scale of 100 ft. to 1 in., show the peculiar nature of their construction, which seems to have been cumulative; that is to say, they have been enlarged in successive periods, the original casing of the earlier portions having been traced. Mr. Petrie says: “Both of these structures have been several times finished, each time with a close-jointed polished casing of the finest white limestone, and then, after each completion, it has been again enlarged by another coat of rough masonry and another line casing outside.”

These two pyramids are the only two genuine stepped pyramids, all the others having had an uniform casing on one slope (excepting Dahshur, as above mentioned). The Pyramid of Sakkara is the only pyramid that does not face exactly north and south. It is nearly of the same general dimensions as the Third Pyramid, that of Mycerinus; but its outline, the disposition of its chambers, and the hieroglyphics found in its interior, all would seem to point it out as an imitation of the older form of mausolea by some king of a far more modern date.

Medum.

Mr. Flinders Petrie’s discoveries in 1891 determined the age and the construction of the Pyramid of Medum,[[37]] erected by Seneferu, a king of the third dynasty, being therefore the oldest pyramid known. Its construction resembles that of the small pyramid of Rikheh and the oblong step pyramid of Sakkara, that is to say, it is a cumulative mastaba, the primal mastaba being about 150 ft. square, and from 37 to 45 ft. high. The outer coatings added were seven in number, and the original mass was carried up and heightened as the circuit was increased, and lastly an outer casing covered over all the steps which had resulted during the construction. The average length of the base was 473 ft. 6 in., the total height being 301 ft. 7 in. According to Mr. Petrie, the Pyramid of Medum, as those of Sakkara and Rikheh, were of a transitional form, in which the original mastaba had been greatly enlarged and subsequently covered over with a casing of pyramidal outline. “That type once arrived at, there was no need for subsequent kings to retain the mastaba form internally, and Khufu and his successors laid out their pyramids of full size at first and built them up at an angle of 51°, and not at 75°, that which is found in the ordinary mastabas.” Mr. Petrie also discovered the temple of the pyramid in the middle of its east side, and almost uninjured. It consisted of a passage entered at the south end of east front, then a small chamber and a courtyard adjoining the side of the pyramid, containing two steles and one altar between them.

In the sepulchral pit of Rahotep, near the pyramid, Mr. Petrie found two arches thrown across a passage to relieve the thrust of the overlapping sides, which carries the use of that feature back to the 4th dynasty.

Tombs.

Around the Pyramids from Abouraash, north of Gizeh to Medum, south of Sakkara, a distance of over 15 miles, forming the Necropolis of Memphis, numberless smaller sepulchres are found, which appear to have been appropriated to private individuals, as the pyramids were—so far as we can ascertain—reserved for kings, or, at all events, for persons of royal blood. These tombs are now known under the term of mastabas, to which we have already referred. The mastaba is a rectangular building varying in size from 15 to 150 ft. in width and length, and from 10 to 80 ft. in height. Their general form is that of a truncated pyramid with an angle of 75° to the horizon, low, and looking exceedingly like a house with sloping walls, with only one door leading to the interior, though they may contain several apartments, and no attempt is made to conceal the entrance. The chambers consist (1) of reception rooms and (2) of serdabs, which are closed cells containing the terra-cotta statuettes which represent the Ka’s or doubles of the deceased. These chambers occupy a part only of the mastaba, the remainder being solid masonry or brickwork. The body seems to have been hidden from profanation by being hid in a pit sunk in the rock, the entrance to which was concealed, and could be approached only through the solid core of the mastaba.

Unlike the pyramids, the walls are covered with the paintings above alluded to, and everything in this “eternal dwelling”[[38]] of the dead is made to resemble the abodes of the living; as was afterwards the case with the Etruscans. It is owing to this circumstance that we are able not only to realise so perfectly the civil life of the Egyptians at this period, but to fix the dates of the whole series by identifying the names of the kings who built the pyramids with those on the walls of the tombs that surround them.[[39]]

Like all early architecture, that of these tombs shows evident symptoms of having been borrowed from a wooden original. The lintels of the doorways are generally rounded, and the walls mere square posts, grooved and jointed together, every part of it being as unlike a stone architecture as can possibly be conceived. Yet the pyramids themselves, and those tombs which are found outside them, are generally far removed from the forms employed in timber structures; and it is only when we find the Egyptians indulging in decorative art that we trace this more primitive style. There are two doorways of this class in the British Museum and many in that of Berlin. One engraved in Lepsius’s work (Woodcut No. [11]) gives a fair idea of this style of decorative art, in the most elaborate form in which we now know it. It is possible that some of its forms may have been derived from brick architecture, but the lintel certainly was of wood, and so it may be suspected were the majority of its features. It certainly is a transitional form, and though we only find it in stone, none of its peculiarities were derived from lithic arts. Perhaps one of the best illustrations of the architectural forms of that day was the sarcophagus of Mycerinus, unfortunately lost on its way to England. It represented a palace, with all the peculiarities found on a larger scale in the buildings which surround the pyramid, and with that peculiar cornice and still more singular roll or ligature on the angles, most evidently a carpentry form, but which the style retained to its latest day.
