The religious evolution which we have noted in the Empire’s early days had made constant progress ever since, and its characteristics had become increasingly accentuated. While the old indigenous gods - Italian, Celtic, Iberian and so on - continued to survive in the faith of the simplest, while official Rome, from the emperor to the lowest civil servant, maintained the cult of the State deities, the inexhaustible Asian Pantheon poured forth a flood of supernatural forces which was constantly being renewed. All these forces found their worshippers in Rome, while, alongside them, all the Asian occultisms, all the esoterisms, together with magic and astrology, seethed and bubbled and spread everywhere.
To obtain some idea of these spiritual eddies into which the pagan soul was swept at this time we must imagine what modern Europe would be like if, alongside a Christianity which remained as an administrative obligation, there existed swarms of Brahmin, Buddhist, Confucian and Moslem sects, and large numbers of spiritualist and theosophical churches; if the wisest folk ran their lives according to their horoscope; and if Tibetan lamas, Indian pandits, Moslem mullahs and voodoo wizards jostled blithely with priests, monks, Protestant ministers and Jewish rabbis in the streets of Paris and London.
