Men-kau-Ra did not find his last resting-place in this upper level of the interior of the pyramid: a narrow passage, hidden behind the slabbing of the second chamber, descended into a secret crypt, lined with granite and covered with a barrel-vaulted roof. The sarcophagus was a single block of blue-black basalt, polished, and carved into the form of a house, with a façade having three doors and three openings in the form of windows, the whole framed in a rounded moulding and surmounted by a projecting cornice such as we are accustomed to see on the temples. The mummy-case of cedar-wood had a man’s head, and was shaped to the form of the human body; it was neither painted nor gilt, but an inscription in two columns, cut on its front, contained the name of the Pharaoh, and a prayer on his behalf. The example given by Khufu, Khaf-Ra, and Men-kau-Ra was by no means lost in later times. From the beginning of the IVth to the end of the XIVth Dynasty--during more than fifteen hundred years--the construction of pyramids was a common state affair, provided for by the administration. Not only did the Pharaohs build them for themselves, but the princes and princesses belonging to the family of the Pharaohs constructed theirs, each one according to his resources; three of these secondary mausoleums are ranged opposite the eastern side of “the Horizon,” three opposite the southern face of “the Supreme,” and everywhere else--near Abusir, at Saqqarah, at Dahshur, or in the Fayum--the majority of the royal pyramids attracted around them a more or less numerous cortège of pyramids of princely foundation often debased in shape and faulty in proportion.[f] THE BUILDERS OF THE PYRAMIDS [Sidenote: [_ca._ 3766-3566 B.C.]] Sneferu is the first ruler of Egypt of whose deeds we know something. A relief with an inscription in Wady Magharah on the peninsula of Sinai represents him as slaying the robber-like tribes of the desert, the Mentu, with a club. According to the inscriptions of the XIIth Dynasty in Sarbut-el-Hadim, it appears that he was considered as founder of the Egyptian dominion in the peninsula of Sinai. His memory was honoured for many years; his worship was often mentioned, and in literary works his bountiful reign was also called to mind. He was probably buried in the Great Pyramid, which has the appearance of terraces, at Medum, the opening of which was begun a short while ago. In one of the neighbouring tombs a statue was found of its architect, Henka, and probably the remaining tombs at Medum belong to this epoch.
