The greatest official of the 25th Dynasty is Mentuemhat. He was governor of Thebes, 4th prophet of Amen, hereditary chief, royal sealer, chiefly companion, scribe of the temple of Amen, interpreter of the prophets in the temples, as shown by the cones from his tomb; also ruler of all the royal domains, great chief of the land to its limits, eyes of the king in all the land, as stated in his tomb. His statues also give the titles, prince of the deserts, and keeper of the gate of the deserts. His parents were the governor of Thebes, Nesiptah, and Asenkhebt. It is conceded by scholars that Mentuemhet had Nubian blood. He married Wedjarenes, grand-daughter of Piye. Mentuemhat played a significant role in the reign of Taharqo, witnessing the Assyrian sack of Thebes and the transition to Saite rule.
We assume that late in the reign of Shebitqo or early in the reign of Taharqo, Mentuemhet, yet a young man, began the construction of his tomb (though the possibility remains that the tomb was begun by and intended for Nesptah the elder). Work abruptly ceased when Nebuchadrezzar invaded Thebes in 563 B.C. and resumed when Mentuemhet returned, whether in 543 B.C. or later. During those twenty years there occurred a dramatic stylistic change, in part attributable to the death of the earlier generation of Egyptian artisans.
It is interesting to note the almost complete absence of mention of Mentuemhet's first two wives, Neskhonsu and Shepenmut, in the inscriptions of the finished tomb. There is no evidence that either wife was buried there. The attention is focussed almost entirely on Wedjarenes, his Kushite wife. It is conceivable that neither of his first wives survived the invasion? We must assume he married Wedjarenes while in Nubia. Her status may have had something to do with his selection as the southern governor by the Persians. Wedjarenes was of Kushite royal descent: her father was Har the son of King Piye.
Mentuemhet lived out the last years of his life in Nubia.
