Now that we have seen what Augustus did, the question arises irresistibly as to the measure of his success. There can be no question but that he was successful in obtaining the immediate object which he was seeking after. A formal religious life was unquestionably brought into being, and such strength as that life had was exerted in behalf of the empire. This is only in part true of the city but it is absolutely true of the provinces, where after all in the long run the balance of power was bound to lie. In every case the religious reform, begun in the city, spread rapidly through the rest of Italy and out into the provinces.
