Nekhtnebf built the Hathor temple and great pylon at Philae, and the east pylon of Karnak, beside temples elsewhere, now vanished.
Monuments of all these kings are known, and art flourished particularly under the MendesiankingsNekhtharheb (Nectanebes or Nectanebus I.) and Nekhtnebf (Nectanebes II.).
He entered Phoenicia with every prospect of success, but having offended Agesilaus he was dethroned in a military revolt which gave the crown to Nekhtnebf or Nectanebes II., the last native king of Egypt.
Agesilaus defeated the rival pretender and left Nekhtnebf established on the throne.
A first expedition was defeated by the Greek mercenaries of Nekhtnebf, ~ut a second, commanded by Ochus himself, subdued Egypt with no further resistance than that of the Greek garrison of Felusium.
Nekhtnebf, instead of endeavouring to relieve them, retreated to Memphis and fled thence to Ethiopia, 340 (?) B.C.
The latest building was a new temple of Nekhtnebf in the XXXth dynasty.
