If Josephus has transcribed and reproduced Manetho correctly there is an obvious contradiction in his narrative. The first shepherd king, Salatis, fortified and peopled Avaris, and placed there a garrison of 240,000 men, for protection against the Assyrians. Then after a lapse of 511 (or according to the excerpt of Africanus of 953) years, when the shepherds had lost Egypt they were shut up in a place containing 10,000 arouræ, _i.e._ a square of twenty-five miles, of the name of Avaris, which they surrounded with a strong wall in order to keep their possessions and booty in security. At last they were compelled to retire even from this, and march out in just the same strength as the garrison which Salatis had placed so long before at Avaris, towards Judæa, and here they founded a second city of Jerusalem, also for protection against the Assyrians. We may leave the Assyrians out of the question, and assume that the reference to them has been transferred by Manetho from the later position which Assyria took up towards Syria and Egypt in the eighth and seventh centuries B.C. to those earlier times; we may also regard the turn of the narrative, which makes the shepherds the ancestors of the Jews and builders of Jerusalem, as a combination invented by Manetho, for in the tradition of the Hebrews there is no hint that their ancestors had once ruled over Egypt for centuries, and Jerusalem down to the time of David was merely the stronghold of a small tribe, the Jebusites. Still it remains inexplicable that these shepherds, who, after they had taken Egypt, or, in order to take it, fortified Avaris, and garrisoned it with 240,000 men, should fortify Avaris a second time centuries later, in order to maintain their last possession in Egypt, and at last march out of Avaris in exactly the same numbers as the garrison originally settled there. Shepherds, _i.e._ nomads, do not make war by building fortresses as a base of operations for extending their conquests; they had nothing to gain by conquering Egypt for the mere purpose of shutting up the whole or the greater part of their numbers with their flocks in a fortified place. On the other hand, it might have seemed advisable to them, when they had subjugated Egypt, to possess a fortified place on the eastern border, in order to keep up a connection with their tribe; and it was natural that the shepherds, when the Egyptians had risen against them with success, and they were no longer able to hold the Delta, should attempt to maintain themselves in the flats and swamps of the Eastern Delta; and when forced to act on the defensive should fortify their camp at Avaris in this district.
