When, during the fourth century, the weakened empire split asunder like an overburdened scale whose beam is broken, this political divorce perpetuated a moral separation that had existed for a long time. The opposition between the Greco-Oriental and the Latin worlds manifests itself especially in religion and in the attitude taken by the central power toward it. Occidental paganism was almost exclusively Latin under the empire. After the annexation of Spain, Gaul and Brittany, the old Iberian, Celtic and other religions were unable to keep up the unequal struggle against the more advanced religion of the conquerors. The marvelous rapidity with which the literature of the civilizing Romans was accepted by the subject peoples has frequently been pointed out. Its influence was felt in the temples as well as in the forum; it transformed the prayers to the gods as well as the conversation between men. Besides, it was part of the political program of the Caesars to make the adoption of the Roman divinities general, and the government imposed the rules of its sacerdotal law as well as the principles of its public and civil law upon its new subjects. The municipal laws prescribed the election of pontiffs and augurs in common with the judicial duumvirs. In Gaul druidism, with its oral traditions embodied in {21} long poems, perished and disappeared less on account of the police measures directed against it than in consequence of its voluntary relinquishment by the Celts, as soon as they came under the ascendency of Latin culture. In Spain it is difficult to find any traces of the aboriginal religions. Even in Africa, where the Punic religion was far more developed, it maintained itself only by assuming an entirely Roman appearance. Baal became Saturn and Eshmoun AEsculapius. It is doubtful if there was one temple in all the provinces of Italy and Gaul where, at the time of the disappearance of idolatry, the ceremonies were celebrated according to native rites and in the local idiom. To this exclusive predominance of Latin is due the fact that it remained the only liturgic language of the Occidental church, which here as in many other cases perpetuated a preexisting condition and maintained a unity previously established. By imposing her speech upon the inhabitants of Ireland and Germany, Christian Rome simply continued the work of assimilation in the barbarian provinces subject to her influence that she had begun while pagan.[1]
