The Roman Empire was at the zenith of its power, and had there not been many admirable administrators and men of worth in the governing caste, such a political consummation could never have been reached and maintained. Moreover, as ever previously in the ancient world, religious liberty was guaranteed, and where we find persecution, as in the reigns of Nero and Domitian, it must be set down to political and not to theological reasons. Setting aside the disputed question of the persecution of the Christians under Domitian, the Neronian persecution was directed against those whom the Imperial power regarded as Jewish political revolutionaries. So, too, when we find the philosophers imprisoned or banished from Rome during these two reigns, it was not because they were philosophers, but because the ideal of some of them was the restoration of the Republic, and this rendered them obnoxious to the charge not only of being political malcontents, but also of actively plotting against the Emperor’s _majestas_. Apollonius, however, was throughout a warm supporter of monarchical rule. When, then, we hear of the philosophers being banished from Rome or being cast into prison, we must remember that this was not a wholesale persecution of philosophy throughout the Empire; and when we say that some of them desired to restore the Republic, we should remember that the vast majority of them refrained from politics, and especially was this the case with the disciples of the religio-philosophical schools. SECTION II. THE RELIGIOUS ASSOCIATIONS AND COMMUNITIES OF THE FIRST CENTURY. In the domain of religion it is quite true that the state cults and national institutions throughout the Empire were almost without exception in a parlous state, and it is to be noticed that Apollonius devoted much time and labour to reviving and purifying them. Indeed, their strength had long left the general state-institutions of religion, where all was now perfunctory; but so far from there being no religious life in the land, in proportion as the official cultus and ancestral institutions afforded no real satisfaction to their religious needs, the more earnestly did the people devote themselves to private cults, and eagerly baptised themselves in all that flood of religious enthusiasm which flowed in with ever increasing volume from the East. Indubitably in all this fermentation there were many excesses, according to our present notions of religious decorum, and also grievous abuses; but at the same time in it many found due satisfaction for their religious emotions, and, if we except those cults which were distinctly vicious, we have to a large extent before us in popular circles the spectacle of what, in their last analysis, are similar phenomena to those enthusiasms which in our own day may be frequently witnessed among such sects as the Shakers or Ranters, and at the general revival meetings of the uninstructed.
