In Rome, as well as in Greece, rationalism took the form of disbelief in divination. Here at least the Epicurean, the Academician, and, among the Stoics, the disciple of Panaetius, were all agreed. But as the sceptical movement began at a much later period in Rome than in the country where it first originated, so also did the supernaturalist reaction come later, the age of Augustus in the one corresponding very nearly with the age of Alexander in the other. Virgil and Livy are remarkable for their faith in omens; and although the latter complains of the general incredulity with which narratives of such events were received, his statements are to be taken rather as an index of what people thought in the age immediately preceding his own, than as an accurate description of contemporary opinion. Certainly nothing could be farther from the truth than to say that signs and prodigies were disregarded by the Romans under the empire. Even the cool and cautious Tacitus feels himself obliged to relate sundry marvellous incidents which seemed to accompany or to prefigure great historical catastrophes; and the more credulous Suetonius has transcribed an immense number of such incidents from the pages of older chroniclers, besides informing us of the extreme attention paid even to trifling omens by Augustus.[341] Meanwhile the recognised methods for looking into futurity continued to enjoy their old popularity, and that which relied on indications afforded by the entrails of sacrifices was practised with unabated confidence down to the time of Julian.[342] Even faith in natural law, where it existed, accommodated itself to the prevalent superstition by taking the form of astrology; and it is well known what reliance the emperor Tiberius, for his time a singularly enlightened man, placed on predictions derived from observation of the starry heavens.
