According to the indications of an Egyptian inscription, Psammetichus strengthened his royal position by taking to wife Shabanatep, the heiress of a dynasty of Thebes. She was, apparently, the daughter of a prince Pianchi, who must have governed the canton of Thebes under Sabakon, and of Ameniritis, the sister of Sabakon, whom he gave to Pianchi to wife.[570] The independence of Egypt was won. After a foreign rule of nearly 80 years (on the lowest calculation the Ethiopians had ruled for 58 years, and the Assyrians nearly 20), Egypt was again her own mistress, and obeyed a king taken from her midst. But every one must have made up his mind to see new armies marching from the Tigris to the Nile, as soon as the rebellion of Samul-sum-ukin was crushed, and Assurbanipal's hands were free. The question was, whether Egypt's power was equal to such a struggle. Psammetichus was not put to this trial. After the capture of Babylon, Assurbanipal turned the full weight of his arms to the subjugation and destruction of Elam. The new conflict must have appeared unavoidable when Assurbanipal, about the year 643 B.C., punished the Arabian tribes on the borders of the Ammonites and Moabites. If he still omitted the attack on Egypt he must have regarded his forces as insufficient for the purpose, or they must have been seriously occupied in another direction. We may assume with tolerable certainty that it was the union of the Median tribes by Phraortes, the son of Deioces, and their combination with the Persians, which drew Assurbanipal back to the East, and kept him there. According to the statement of Herodotus, already considered, Psammetichus on his side advanced to the offensive beyond his own borders towards Syria. This war of Psammetichus in Syria, and the supposed long conflict for Ashdod, can only mean that Psammetichus attempted to bring the cities of the Philistines, and especially those of the desert, into his hands, in order to make the march through the desert, which must commence from this point, impossible, or at any rate difficult, for the Assyrians. Here also we are ignorant whether Psammetichus had to contend with the Philistines alone or with the Assyrian forces also: this only is clear, that he could not besiege Ashdod before Gaza and Ascalon were in his hands. If Psammetichus was really moved to this war by the object we impute to him, we must put the war in the period in which there was still danger to be apprehended from the Tigris: _i.e._ in the decade from 640 to 630 B.C. According to this, the impossible 29 years which Herodotus allows to the siege of Ashdod must be reduced to nine years, just as we had to cut down the 28 years which he gives for the dominion of the Scythians in Hither Asia to about ten years. But in the advance of these Scythians towards Egypt (in the year 625 B.C.), described by Herodotus, he does not tell us that Ashdod, Ascalon, or Gaza, were subject to Psammetichus;
