That the new princes, soon after the conquest, attempted to approximate their position as much as possible to that of the ancient Pharaohs may be concluded from the mere fact that Manetho was in a position to give a catalogue of their reigns by years and months. But this is proved more definitely still by certain monuments. In the neighbourhood of Lake Menzaleh, among the ruins of the ancient Tanis, the modern San, two old statues have been discovered, the forms and lineaments of which exhibit a physique different from the Egyptian. In the heads of four sphinxes, discovered in the same place, it is thought that we may recognise the portraits of four shepherd kings, and a colossus discovered at Tel Mokdam is said to bear the following inscription:--"The good god, the star of both worlds, the child of the sun, Sel Salati, beloved by Sutech, the lord of Hauar.[182]" The six shepherd kings enumerated by Josephus from the Egyptian History of Manetho reigned, according to the dates given by the latter, for 260 years, _i.e._ from the year 2101 B.C., in which, on Lepsius's arrangement, the irruption of the shepherds took place, till the year 1842 B.C. Their successors must therefore have ruled over Egypt for 251 years more, _i.e._, down to the year 1591 B.C. But in the time of the later shepherd kings, native princes again arose in Upper Egypt, although subject to tribute. A papyrus of the British Museum tells us: "It so happened that the land of Egypt became the possession of her enemies, and when this took place there was no king. And behold Raskenen became king of the country in the south. The enemy were in possession of the fortress of Aamu (p. 120), and their chief, Ra Apepi was at Hauar. The whole land paid tribute to him, and rendered service of all kinds, and brought to him the produce of Lower Egypt. King Apepi chose Sutech as his lord, and served no other god, and built him a temple of firm and lasting structure."[183] The power of the native princes at Thebes must have been gradually strengthened till the successors of Raskenen were in a position to press forward towards Lower Egypt, and place limits on the sway of the shepherd kings, and finally to drive them entirely out of Egypt. Josephus has already told us from Manetho that the princes of Thebes and the rest of Egypt rose up against the shepherds, and in consequence a long and severe struggle took place between them. In Manetho's list the series of shepherd kings is followed by Amosis of Thebes (1684-1659 B.C.). Hence we may assume that it was under this prince that the kingdom of Thebes got the upper hand, and the power of the shepherd kings was restricted to the Eastern Delta.
