A hieratic inscription upon the sarcophagus of Queen Khnem-nefert, wife of Mentu-hetep, a king of the Eleventh Dynasty (_c._ 2500 B.C.), states that a certain chapter of the _Book of the Dead_ was discovered in the reign of Hesep-ti, the fifth king of the First Dynasty, who flourished about 4266 B.C. This sarcophagus affords us two copies of the said chapter, one immediately following the other. That as early as 2500 B.C. a chapter of the _Book of the Dead_ should be referred to a date almost 2000 years before that time is astounding, and the mind reels before the idea of a tradition which, during comparatively unlettered centuries, could have conserved a religious formula almost unimpaired. Thus thirty-four centuries ago a portion of the _Book of the Dead_ was regarded as extremely ancient, mysterious, and difficult of comprehension. It will be noted also that the inscription on the tomb of Queen Khnem-nefert bears out that the chapter in question was 'discovered' about 4266 B.C. If it was merely discovered at that early era, what periods of remoteness lie between that epoch and the time when it was first reduced to writing? The description of the chapter on the sarcophagus of the royal lady states that "this chapter was found in the foundations beneath the Dweller in the Hennu Boat by the foreman of the builders in the time of the king of the South and North, Hesep-ti, whose word is truth"; and the Nebseni Papyrus says that the chapter was found in the city of Khemennu or Hermopolis, on a block of alabaster, written in letters of lapis-lazuli, under the feet of the god. It also appears from the Turin Papyrus, which dates from the period of the Twenty-sixth Dynasty, that the name of the finder was Heru-ta-ta-f, the son of Cheops, who was at the time engaged in a tour of inspection of the temples. Sir Gaston Maspero is doubtful concerning the importance which should be attached to the statement regarding the chapter on the tomb of Queen Khnem-nefert, but M. Naville considers the chapter in question one of the oldest in the _Book of the Dead_.
