Khufu was succeeded by =Ṭeṭ-f-Rā=, of whom nothing is known; and he again was succeeded by =Khā-f-Rā=, the =Chephren= of the Greek writers, who is famous chiefly as the builder of the =Second Pyramid= at Gîzah, called in Egyptian “Ur” 𓅨𓉴, _i.e._, the “Great.” Its height is about 450 feet, the length of each side at the base is 700 feet, and it is said to contain about 60,000,000 cubic feet of masonry, weighing some 4,883,000 tons. It was first opened by Belzoni (born 1778, died 1823) in 1816. It was originally cased with polished stone, but only towards the top has the casing been preserved. The illustration on page 171 shows the arrangement of the corridor and sarcophagus chamber, which is very different from that of the Great Pyramid. A funerary chapel was attached to the pyramid; and among those who ministered in it was =Rutchek=, the chief of the libationer priests, who calls himself a “friend of Pharaoh” 𓋴𓍋𓈖𓉐𓐰𓉻. (For an architrave and an inscription from his tomb see Egyptian Vestibule, Nos. =22= and =23=.) The Pyramid itself was in charge of the “royal kinsman” =Thethȧ=, who was the royal steward, and “overseer of the throne of Pharaoh,” and priest of Hathor and Neith. Two fine doors from the maṣṭaba tomb of Thethȧ are exhibited in the Northern Egyptian Gallery (Bay 1, Nos. =24= and =25=), together with a short inscription referring to the burial of his father and mother (No. =26=). The perfection to which the sculptor’s art had attained at this period is well illustrated by the casts of =statues= of =Chephren=, from the hard stone originals in the Museum in Cairo, exhibited in the Egyptian Vestibule, Nos. =27= and =28=. A fragment of an alabaster vessel from the king’s tomb, bearing his name, is in Wall-case 138 in the Fourth Egyptian Room, No. 56. [Illustration: King Menkaurā (Mykerinos).
