The breast of Symmachus was animated by the warmest zeal for the cause of expiring Paganism; and his religious antagonists lamented the abuse of his genius, and the inefficacy of his moral virtues. The orator, whose petition is extant to the emperor Valentinian, was conscious of the difficulty and danger of the office which he had assumed. He cautiously avoids every topic which might appear to reflect on the religion of his sovereign; humbly declares, that prayers and entreaties are his only arms; and artfully draws his arguments from the schools of rhetoric, rather than from those of philosophy. Symmachus endeavors to seduce the imagination of a young prince, by displaying the attributes of the goddess of victory; he insinuates, that the confiscation of the revenues, which were consecrated to the service of the gods, was a measure unworthy of his liberal and disinterested character; and he maintains, that the Roman sacrifices would be deprived of their force and energy, if they were no longer celebrated at the expense, as well as in the name, of the republic. Even scepticism is made to supply an apology for superstition. The great and incomprehensible secret of the universe eludes the inquiry of man. Where reason cannot instruct, custom may be permitted to guide; and every nation seems to consult the dictates of prudence, by a faithful attachment to those rites and opinions, which have received the sanction of ages. If those ages have been crowned with glory and prosperity, if the devout people have frequently obtained the blessings which they have solicited at the altars of the gods, it must appear still more advisable to persist in the same salutary practice; and not to risk the unknown perils that may attend any rash innovations. The test of antiquity and success was applied with singular advantage to the religion of Numa; and Rome herself, the celestial genius that presided over the fates of the city, is introduced by the orator to plead her own cause before the tribunal of the emperors. "Most excellent princes," says the venerable matron, "fathers of your country! pity and respect my age, which has hitherto flowed in an uninterrupted course of piety. Since I do not repent, permit me to continue in the practice of my ancient rites. Since I am born free, allow me to enjoy my domestic institutions. This religion has reduced the world under my laws. These rites have repelled Hannibal from the city, and the Gauls from the Capitol. Were my gray hairs reserved for such intolerable disgrace? I am ignorant of the new system that I am required to adopt; but I am well assured, that the correction of old age is always an ungrateful and ignominious office." The fears of the people supplied what the discretion of the orator had suppressed; and the calamities, which afflicted, or threatened, the declining empire, were unanimously imputed, by the Pagans, to the new religion of Christ and of Constantine.
But the hopes of Symmachus were repeatedly baffled by the firm and dexterous opposition of the archbishop of Milan, who fortified the emperors against the fallacious eloquence of the advocate of Rome. In this controversy, Ambrose condescends to speak the language of a philosopher, and to ask, with some contempt, why it should be thought necessary to introduce an imaginary and invisible power, as the cause of those victories, which were sufficiently explained by the valor and discipline of the legions. He justly derides the absurd reverence for antiquity, which could only tend to discourage the improvements of art, and to replunge the human race into their original barbarism. From thence, gradually rising to a more lofty and theological tone, he pronounces, that Christianity alone is the doctrine of truth and salvation; and that every mode of Polytheism conducts its deluded votaries, through the paths of error, to the abyss of eternal perdition. Arguments like these, when they were suggested by a favorite bishop, had power to prevent the restoration of the altar of Victory; but the same arguments fell, with much more energy and effect,
