The Roman gods afforded no good theme for poetry and art, and when they were to be used as such they were invariably replaced by loans from the Greeks. But, as in the face of Greek free-thought and Greek criticism of religion, they had the advantage that the vital point for attack was lacking. All the objectionable tales of the exploits of the gods and the associated ideas about their nature which had prompted the Greek attack on the popular faith simply did not exist in Roman religion. On the other hand, its rites were in many points more primitive than the Greek ones, but Greek philosophy had been very reserved in its criticism of ritual. We may thus no doubt take it for granted, though we have no direct evidence to that effect, that even Romans with a Greek education long regarded the Greek criticism of religion as something foreign which was none of their concern. That a time came when all this was changed; that towards the end of the Republic great scepticism concerning the established religion of Rome was found among the upper classes, is beyond doubt, and we shall subsequently find occasion to consider this more closely. In this connexion another circumstance demands attention, one which, moreover, has by some been associated with Greek influence among the upper classes, namely, the decay of the established worship of the Roman State during the last years of the Republic. Of the actual facts there can hardly be any doubt, though we know very little about them. The decisive symptoms are: that Augustus, after having taken over the government, had to repair some eighty dilapidated temples in Rome and reinstitute a series of religious rites and priesthoods which had ceased to function. Among them was one of the most important, that of the priest of Jupiter, an office which had been vacant for more than seventy-five years (87-11 B.C.), because it excluded the holder from a political career. Further, that complaints were made of private persons encroaching on places that were reserved for religious worship; and that Varro, when writing his great work on the Roman religion, in many cases was unable to discover what god was the object of an existing cult; and generally, according to his own statement he wrote his work, among other things, in order to save great portions of the old Roman religion from falling into utter oblivion on account of the indifference of the Romans themselves. It is obvious that such a state of affairs would have been impossible in a community where the traditional religion was a living power, not only formally acknowledged by everybody, but felt to be a necessary of life, the spiritual daily bread, as it were, of the nation.
