At a somewhat later period arrived the numerous and varied Baals of Syria. The great economic movement starting at the beginning of our era which produced the colonization of the Latin world by Syrian slaves and merchants, not only modified the material civilization of Europe, but also its conceptions and beliefs. The Semitic cults entered into successful competition with those of Asia Minor and Egypt. They may not have had so stirring a liturgy, nor have been so thoroughly absorbed in preoccupation with a future {199} life, although they taught an original eschatology, but they did have an infinitely higher idea of divinity. The Chaldean astrology, of which the Syrian priests were enthusiastic disciples, had furnished them with the elements of a scientific theology. It had led them to the notion of a God residing far from the earth above the zone of the stars, a God almighty, universal and eternal. Everything on earth was determined by the revolutions of the heavens according to infinite cycles of years. It had taught them at the same time the worship of the sun, the radiant source of earthly life and human intelligence. The learned doctrines of the Babylonians had also imposed themselves upon the Persian mysteries of Mithra which considered time identified with heaven as the supreme cause, and deified the stars; but they had superimposed themselves upon the ancient Mazdean creed without destroying it. Thus the essential principles of the religion of Iran, the secular and often successful rival of Greece, penetrated into the Occident under cover of Chaldean wisdom. The Mithra worship, the last and highest manifestation of ancient paganism, had Persian dualism for its fundamental dogma. The world is the scene and the stake of a contest between good and evil, Ormuzd and Ahriman, gods and demons, and from this primary conception of the universe flowed a strong and pure system of ethics. Life is a combat; soldiers under the command of Mithra, invincible heroes of the faith, must ceaselessly oppose the undertakings of the infernal powers which sow corruption broadcast. This imperative ethics was productive of energy and formed the characteristic {200} feature distinguishing Mithraism from all other Oriental cults. Thus every one of the Levantine countries--and that is what we meant to show in this brief recapitulation--had enriched Roman paganism with new beliefs that were frequently destined to outlive it. What was the result of this confusion of heterogeneous doctrines whose multiplicity was extreme and whose values were very different? How did the barbaric ideas refine themselves and combine with each other when thrown into the fiery crucible of imperial syncretism? In other words, what shape was assumed by ancient idolatry, so impregnated with exotic theories during the fourth century, when it was finally dethroned? It is this point that we should like to indicate briefly as the conclusion to these studies.
