The Museum and Library represented only one of the three sides of the triple city of Alexandria. They represented the Aristotelian, the Hellenic, and Macedonian element. But Ptolemy I had brought together two other factors to this strange centre. First there was a great number of Jews, brought partly from Palestine, but largely also from those settlements in Egypt which had never returned to Jerusalem; these latter were the Jews of the Diaspora or Dispersion, a race of Jews who, as we have already noted in Chapter XXI, had not shared the Babylonian Captivity, but who were nevertheless in possession of the Bible and in close correspondence with their co-religionists throughout the world. These Jews populated so great a quarter of Alexandria that the town became the largest Jewish city in the world, with far more Jews in it than there were in Jerusalem. We have already noted that they had found it necessary to translate their scriptures into Greek. And, finally, there was a great population of native Egyptians, also for the most part speaking Greek, but with the superstitious temperament of the dark whites and with the vast tradition of forty centuries of temple religion and temple sacrifices at the back of their minds. In Alexandria three types of mind and spirit met, the three main types of the white race, the clear-headed criticism of the Aryan Greek, the moral fervour and monotheism of the Semitic Jew, and the deep Mediterranean tradition of mysteries and sacrifices that we have already seen at work in the secret cults and occult practices of Greece, ideas which in Hamitic Egypt ruled proudly in great temples in the open light of day.
These three were the permanent elements of the Alexandrian blend. But in the seaport and markets mingled men of every known race, comparing their religious ideas and customs. It is even related that in the third century B.C. Buddhist missionaries came from the court of King Asoka in India. Aristotle remarks in his Politics that the religious beliefs of men are apt to borrow their form from political institutions, "men assimilate the lives no less than the bodily forms of the gods to their own," and this age of Greek-speaking great empires under autocratic monarchs was bearing hardly upon those merely local celebrities, the old tribal and city deities. Men were requiring deities with an outlook at least as wide as the empires, and except where the interests of
