Mykerinos was not, it appears, the eldest son and appointed heir of Khephren; while still a mere prince he was preparing for himself a pyramid similar to those which lie near the “Horizon,” when the deaths of his father and brother called him to the throne. What was sufficient for him as a child, was no longer suitable for him as a Pharaoh; the mass of the structure was increased to its present dimensions, and a new inclined passage was effected in it, at the end of which a hall panelled with granite gave access to a kind of antechamber.* The latter communicated by a horizontal corridor with the first vault, which was deepened for the occasion; the old entrance, now no longer of use, was roughly filled up.** * Vyse discovered here fragments of a granite sarcophagus, perhaps that of the queen; the legends which Herodotus (ii. 134, 135), and several Greek authors after him, tell concerning this, show clearly that an ancient tradition assumed the existence of a female mummy in the third pyramid alongside of that of the founder Mykerinos. ** Vyse has noticed, in regard to the details of the structure, that the passage now filled up is the only one driven from the outside to the interior; all the others were made from the inside to the outside, and consequently at a period when this passage, being the only means of penetrating into the interior of the monument, had not yet received its present dimensions. Mykerinos 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.* * It was lost off the coast of Spain in the vessel which was bringing it to England. We have only the drawing remaining which was made at the time of its discovery, and published by Vyse. M. Borchardt has attempted to show that it was reworked under the XXVIth Saite dynasty as well as the wooden coffin of the king.
