If the Roman conquest did not altogether put an end to these sentiments, it considerably mitigated their intensity. The imperial city was too strong to feel endangered by the introduction of alien deities within its precincts. The subject states were relieved from anxiety with regard to a political independence which they had irrecoverably lost. Moreover, since the conquests of Alexander, vast aggregations of human beings had come into existence, to which the ancient exclusiveness was unknown, because they never had been cities at all in the ancient sense of the word. Such were Alexandria and Antioch, and these speedily became centres of religious syncretism. Rome herself, in becoming the capital of an immense empire, acquired the same cosmopolitan character. Her population consisted for the most part of emancipated slaves, and of adventurers from all parts of the world, many of whom had brought their national faiths with them, while all were ready to embrace any new faith which had superior attractions to offer. Another important agent in the diffusion and propagation of new religions was the army. The legions constituted a sort of migratory city, recruited from all parts of the empire, and moving over its whole extent. The dangers of a military life combined with its authoritative ideas are highly favourable to devotion; and the soldiers could readily adopt new modes for the expression of this feeling both from each other and from the inhabitants of the countries where they were stationed, and would in turn204 become missionaries for their dissemination over the most distant regions.

Now, the deliberate verdict of their philosophy on the relation between beauty and virtue is contained in the following passage from Platos Laws:The general condition of the town was not calmer during these last days. New hostages were taken continually, and generally, as before, they were clerics, in consequence of which the religious services were in a continual muddle, and sometimes on Sundays no Holy Mass could be said. Burgomaster Nerinx had now posted proclamations in which he called for volunteers to serve as temporary hostages, instead of the priests, during the hours of religious service. As if it were office work they mentioned: "The service begins in the afternoon at ... o'clock and will end after ... days at ... o'clock."
