I. With a passing glance at the progress of this unity, which, great and magnificent as it is, is yet external, let us turn to an object filling the whole of this vast empire with its varied manifestations: for this object leads us to the consideration of another unity, wholly internal, without which that of government, law, and order must be apparent rather than real, or at best, however seemingly imposing, be deprived of the greater part of its efficacy. 1. It has been said that the empire contained in it many lands and many races, but these likewise worshipped their own distinct gods, which were acknowledged and sanctioned as national divinities for the several countries wherein they were locally established. Had Augustus ordered an enrolment not only of the numbers, the landed property, and the wealth of his subjects, but of their gods, his public register, or Breviarium, would have included at least ten distinct systems of idolatrous worship. First of all, there would be the proper gods of Rome, then those of the Hellenic race; and these, though the most similar to each other, yet refused a complete amalgamation. But besides these there were on the west the Etrurian, the Iberian, the Gallic, and the Germanic gods; on the east, the Carian and Phrygian, the Syrian, the Assyrian, the Arabian; on the south, the Phœnician, Libyan, and Egyptian. All these different races, inasmuch as they were subjects of the empire, enjoyed undisturbed the right of worshipping their ancestral gods,(1) who, so long as they did not overstep their local boundaries, were recognised; they possessed priests, rites, temples, estates, and self-government; they held the soil, and their worship was legal. It was a matter of Roman policy not to interfere with them. Nay, their several worshippers could carry their rites along with them in their various sojourns and settlements, and even in Rome build altars, and adore Egyptian, Asiatic, African, or Gallic gods. These various systems agreed all in one point, that they were systems of polytheistic idolatry: they all divided the attributes of the godhead, assigning them to more or fewer objects, and worshipping all these by visible symbols which the power worshipped was deemed to inhabit:(2) but they did not make the same division with a mere difference of name; on the contrary, they ran into and across each other with the most bewildering multiplicity, variation, and contradiction. Even in the same system, if we may give this name to any of the various mythologies, the several divinities were perpetually interfering with each other’s province. When the Roman made vows for the removal of his ailments, in his uncertainty to which god the ailment belonged, or who was most proper to remove it, he addressed his vow to several together; or in public supplications, being often uncertain to whom exactly the prayer or offering should be made, he cautiously expressed himself, “whether it be a god or a goddess.” And the
