Caesar's Treatment of Matters in the Capital
Caesar did not deplore, but he sought to help so far as help was possible. Rome remained, of course, what it was-- a cosmopolitan city. Not only would the attempt to give to it once more a specifically Italian character have been impracticable; it would not have suited Caesar's plan. Just as Alexander found for his Graeco-Oriental empire an appropriate capital in the Greek, Jewish, Egyptian, and above all cosmopolitan, Alexandria, so the capital of the new Romano-Greek universal empire, situated at the meeting-point of the east and the west, was to be not an Italian community, but the denationalized capital of many nations.
For this reason Caesar tolerated the worship of the newly-settled Egyptian gods alongside of Father Jovis, and granted even to the Jews the free exercise of their strangely foreign ritual in the very capital of the empire. However offensive was the motley mixture of the parasitic--especially the Graeco-Oriental-- population in Rome, he nowhere opposed its extension; it is significant, that at his popular festivals for the capital he caused dramas to be performed not merely in Latin and Greek, but also in other languages, presumably in Phoenician, Hebrew, Syrian, Spanish.
