From these conquests and annexations in Asia Minor and Syria dates the sudden propagation of the Persian mysteries of Mithra in the Occident. For even though a congregation of their votaries seems to have existed at Rome under Pompey as early as 67 B. C., the real diffusion of the mysteries began with the Flavians toward the end of the first century of our era. They became more and more prominent under the Antonines and the Severi, and remained the most important cult of paganism until the end of the fourth century. Through them as a medium the original doctrines of Mazdaism were widely propagated in every Latin province, and in order to appreciate the influence of Persia upon the Roman creeds, we must now give them our careful attention.
However, it must be said that the growing influence of Persia did not manifest itself solely in the religious sphere. After the accession of the Sassanid dynasty (228 A. D.) the country once more became conscious of its originality, again resumed the cultivation of national traditions, reorganized the hierarchy of its official clergy and recovered the political cohesion which had been wanting under the Parthians. It felt { 141} and showed its superiority over the neighboring empire that was then torn by factions, thrown upon the mercy of manifestoes, and ruined economically and morally. The studies now being made in the history of that period show more and more that debilitated Rome had become the imitator of Persia.
In the opinion of contemporaries the court of Diocletian, prostrating itself before a master who was regarded as the equal of God, with its complicated hierarchy and crowd of eunuchs that disgraced it, was an imitation of the court of the Sassanides. Galerius declared in unmistakable terms that Persian absolutism must be introduced in his empire,[11] and the ancient Cæsarism founded on the will of the people seemed about to be transformed into a sort of caliphate.
Recent discoveries also throw light upon a powerful artistic school that developed in the Parthian empire and later in that of the Sassanides and which grew up independently of the Greek centers of production. Even if it took certain models from the Hellenic sculpture or architecture, it combined them with Oriental motives into a decoration of exuberant richness. Its field of influence extended far beyond Mesopotamia into the south of Syria where it has left monuments of unequalled splendor. The radiance of that brilliant center undoubtedly illuminated Byzantium, the barbarians of the north, and even China.[12]
