As for the manners and habits of life, it is unnecessary to point out how vastly different they were from those of Persia. Public contempt punished the young, wealthy, pleasure-loving cosmopolitan, who attempted to live in Persian style. Thus, until the time of Alexander, when the power of Greece had arrived at its culminating point, Persia, with all her preponderance, could not convert Hellas to her civilization. In the time of Alexander, this incompatibility of dissimilar modes of culture was singularly demonstrated. When the empire of Darius succumbed to the Macedonian phalanxes, it was expected, for a time, that a Hellenic civilization would spread over Asia. There seemed the more reason for this belief when the conqueror, in a moment of aberrancy, treated the monuments of the land with such aggressive violence as seemed to evince equal hatred and contempt. But the wanton incendiary of Persepolis soon changed his mind, and so completely, that his design became apparent to simply substitute himself in the room of the dynasty of Achæmenes, and rule over Persia like a Persian king, with Greece added to his estates. Great as was Alexander's power, it was insufficient for the execution of such a project. His generals and soldiers could not brook to see their commander assume the long flowing robes of the eastern kings, surround himself with eunuchs, and renounce the habits and manners of his native land. Though after his death some of his successors persisted in the same system, they were compelled greatly to mitigate it. Where the population consisted of a motley compound of Greeks, Syrians, and Arabs, as in Egypt and the coast of Asia Minor, a sort of compromise between the two civilizations became thenceforth the normal state of the country; but where the races remained unmixed, the national manners were preserved. In the latter periods of the Roman empire, the two civilizations had become completely blended in the whole East, including continental Greece; but it was tinged more with the Asiatic than the Greek tendencies, because the masses belonged much more to the former element than to the latter. Hellenic forms, it is true, still subsisted, but it is not difficult to discover in the ideas of those periods and countries the Oriental stock upon which the scions of the Alexandrian school had been engrafted. The respective influence of the various elements was in strict proportion to the quantity of blood; the intellectual preponderance belonged to that which had contributed the greatest share. The same antagonism which I pointed out between the intellectual culture of the Greeks and that of the Persians, will be found to result from the contact of all other widely different civilizations. I shall mention but one more instance: the relations between the Arab civilization[181] and our own.
