But Amasis found the Greeks more indispensable than ever, and they were loaded with favours even more than before. They were moved to Memphis that they might be close to the king, and at the same time overawe the native Egyptians, and Amasis himself married a Greek wife. The invasion of Egypt by Nebuchadrezzar in B.C. 567 showed that the policy of Amasis had been a wise one. The Babylonians were unable to penetrate beyond the eastern part of the Delta; the Greek troops fought too well. The limits of the Babylonian empire were permanently fixed at the frontiers of Palestine.
That empire, however, was overthrown by Cyrus, and it was easy to see that the conqueror who had proved so irresistible in Asia would not allow Egypt to remain at peace. Amasis prepared himself accordingly for the coming storm. Cyprus was occupied, and therewith the command of the sea was assured. The maritime policy of the Twenty-sixth dynasty was an indication of Greek influence; in older days the sea had been to the Egyptian a thing abhorred.
Kambyses carried out the invasion which his father, Cyrus, had planned. Unfortunately for the Egyptians, Amasis died while the Persian army was on its march, and the task of opposing it fell to his young and inexperienced son. The Greek mercenaries fought bravely, but to no purpose: the battle of Pelusium gave Egypt to the invader, Memphis was taken, and the Pharaoh put to death. In the long struggle between Asia and Egypt, Asia had been finally the victor.
The Egyptians did not submit tamely to the Persian yoke. Kambyses indeed seemed inclined to change himself into an Egyptian Pharaoh; he took up his residence at Memphis and sent an expedition to conquer the Sudân. But under Darius and his successors, whose Zoroastrian monotheism was of a sterner description, there was but little sympathy between the conquered and their conquerors. Time after time the Egyptians broke into revolt, once against Xerxes, once again against Artaxerxes I., and a third time against Artaxerxes II. The last insurrection was more successful than those which had preceded it, and Egypt remained independent for sixty-five years. Then the crimes and incompetence of its last native king, Nektanebo II., opened the way to the Persian, and the valley of the Nile once more bowed its neck under the Persian yoke. Its temples were ruined, the sacred Apis slain, and an ass set up in mockery in its place.
A few years later Egypt welcomed the Macedonian Alexander as a deliverer, and recognised him as a god. The line of the Pharaohs, the incarnations of the Sun-god, had returned in him to the earth. It was not the first time that the Egyptian and the Greek had stood side by side against the common Persian foe. Greek troops had disputed the passage of Kambyses into Egypt. The first revolt of Egypt had saved Greece from the impending invasion of Darius, and postponed it to the reign of his feebler son, and during its second revolt Athenian ships had sailed up the Nile and assisted the Egyptians in the contest with the Persians. If Egypt could not be free, it was better that its master should be a Greek.
Alexander was followed by the Ptolemies. They were the ablest of his successors, the earlier of them being equally great in war and in peace. Alexandria, founded by Alexander on the site of the village of Rakotis, became the commercial and literary centre of the world; thousands of books were collected in its Library, and learned professors lectured in the halls of its Museum. An elaborate fiscal system was devised and carefully superintended, and enormous revenues poured into the treasury of the king. As time passed on, the Ptolemies identified themselves more and more with their subjects; the temples were rebuilt or restored, and the Greek king assumed the attributes of a Pharaoh. The Jews flocked into the country, where special privileges were granted to them, and where many of them were raised to offices of state. A rival temple to that of Jerusalem was built at Onion near Heliopolis, the modern Tel el-Yahudîya, or "Mound of the Jews," and the books of the Hebrew Scriptures were translated into Greek. A copy of the Septuagint, as the Greek translation was called, was needed for the Alexandrine Library.
Egypt, once the house of bondage, thus became a second house of Israel. It gave the world a new version of the Hebrew Bible which largely influenced the writers of the New Testament; it gave it also a new Canon which was adopted by the early Christian Church. The prophecy of Isaiah was fulfilled: "The Lord shall be known to Egypt, and the Egyptians shall know the Lord."
In the course of centuries, however, the monotheistic element in Egyptian religion had grown clearer and more pronounced in the minds of the educated classes. The gods of the official cult ceased to be regarded as different forms of the same deity; they became mere manifestations of a single all-pervading power. As M. Grébaut puts it: they were "the names received by a single Being in his various attributes and workings.... As the Eternal, who existed before all worlds, then as organiser of the universe, and finally as the Providence who each day watches over his work, he is always the same being, reuniting in his essence all the attributes of divinity." It was the hidden God who was adored under the name whatever the latter might be, the God who is described in the texts as "without form" and "whose name is a mystery," and of whom it is said that He is the one God, "beside whom there is no other." In Ptah of Memphis or Amon of Thebes or Ra of Heliopolis, the more educated Egyptian recognised but a name and symbol for the deity which underlay them all.
Along with this growth in a spiritual conception of religion went, as was natural, a growth in scepticism. There was a sceptical as well as a believing school, such as finds its expression in the festal Dirge of King Antef of the Eleventh dynasty. Here we read in Canon Rawnsley's versified translation—
"What is fortune? say the wise.
