In the world of thought no less than in the world of action, the boundless license which characterised the last days of Roman republicanism was followed by a period of tranquillity and restraint. Augustus endeavoured to associate his system of imperialism with a revival of religious authority. By his orders a great number of ruinous temples were restored, and the old ceremonies were celebrated once more with all their former pomp. His efforts in this direction were ably seconded by the greatest poet and the greatest historian of the age. Both Virgil and Livy were animated by a warm religious feeling, associated, at least in the case of the latter, with a credulity which knew no bounds. With both, religion took an antiquarian form. They were convinced that Rome had grown great through faith in the gods, that she had a divine mandate to conquer the world, and that this supernatural mission might be most clearly perceived in the circumstances of her first origin.[307] It is also characteristic that both should have been provincials, educated in the traditions of a reverent conservatism, and sympathising chiefly with those elements in the constitution of Rome which brought her nearest to primitive Italian habits and ideas. Now it was not merely the policy, it was the inevitable consequence of imperialism to favour the provinces[308] at the expense of the capital, by depriving the urban population and the senatorial aristocracy of the political preponderance which they had formerly enjoyed. Here, as in most other instances, what we call a reaction did not mean a change in the opinions or sentiments of any particular persons or classes, but the advent of a new class whose ways of thinking now determined the general tone of the public mind.
