=Tetȧ=, the first king of this dynasty, was neither a warrior nor a great builder; and details of his reign are wanting. He built a pyramid at Ṣaḳḳârah, the interior of the chambers and corridors of which are covered with inscriptions of a religious character; it is commonly known as the “Prison Pyramid.” Of the monuments of this king in the British Museum may be mentioned a =grant of land= to the god Khenti Ȧmenti of Abydos (Egyptian Vestibule, No. =74=); an alabaster =vase= from his pyramid, inscribed with his name and titles (Wall-case 138 in the Fourth Egyptian Room, Nos. 59 and 60); and a fine breccia =bull=, to which the royal names and titles have been added in recent times (No. 61). Rā-meri, =or Pepi I=, was probably the greatest king of this dynasty. He worked the granite quarries at Elephantine, or Syene, and in the Wâdî Ḥammâmât, and he established his power in the Peninsula of Sinai, where he ruled the local tribes with a strong hand. His reign was one of industrial progress; and trade and handicrafts flourished throughout the country under his fostering care. Under the leadership of a favourite official named =Unȧ=, he despatched a very large army composed of men drawn from all parts of the Sûdân, to put down a wide-spread revolt which had broken out among the dwellers in the Eastern Desert called “the Āamu, who lived on the sand.” Unȧ gained a decisive victory, and was promoted to very high honours. Pepi I built a pyramid at Ṣaḳḳârah, the walls of the chambers and corridors of which were covered with inscriptions of a religious character; from this comes the fine alabaster =vase=, inscribed with his name and titles, in Wall-case 138 in the Fourth Egyptian Room, No. 66. (For two fine “false doors” from the tomb of =Qarta=, a high official of Pepi I, see Egyptian Vestibule, Nos. =75=, =76=.)
