them.[[72]] Later, a more immediate influence was exercised upon the Roman world by the Persian colonies of Asia Minor,[[73]] who retained an obstinate faith in their ancient national beliefs.
The particular importance attributed to magic by the Mazdeans is a necessary consequence of their dualist system, which has been treated by us before.[[74]] Ormuzd, residing in the heavens of light, is opposed by his irreconcilable adversary, Ahriman, ruler of the underworld. The one stands for light, truth, and goodness, the other for darkness, falsehood, and perversity. The one commands the kind spirits which protect the pious believer, the other is master over demons whose malice causes all the evils that afflict humanity. These opposite principles fight for the domination of the earth, and each creates favorable or noxious animals and plants. Everything on earth is either heavenly or infernal. Ahriman and his demons, who surround man to tempt or hurt him,[[75]] are evil gods and entirely different from those of which Ormuzd's host consists. The magician sacrifices to them, either to avert evils they threaten, or to direct their ire against enemies of true belief, and the impure spirits rejoice in bloody immolations and delight in the fumes of flesh burning on the altars.[[76]] Terrible acts and words attended all immolations. Plutarch[[77]] mentions an example of the dark sacrifices of the Mazdeans. "In a mortar," he says, "they pound a certain herb called wild garlic, at the same time invoking Hades (Ahriman), and the powers of darkness, then stirring this herb in the blood of a slaughtered wolf, they take it away and drop it on a spot never reached by the rays of the sun." A necromantic performance indeed.
We can imagine the new strength which such a conception of the universe must have given to magic. It was no longer an incongruous collection of popular superstitions and scientific observations. It became a reversed religion: its nocturnal rites were the dreadful liturgy of the infernal powers. There was no miracle the experienced magician might not expect to perform with the aid of the demons, providing he know how to master them; he would invent any atrocity in his desire to gain the favor of the evil divinities whom crime gratified and suffering pleased. Hence the number of impious practices performed in the dark, practices the horror of which is equaled only by their absurdity: preparing beverages that disturbed the senses and impaired the intellect; mixing subtle poisons extracted from demoniac plants and corpses already in a state of putridity;[[78]] immolating children in order to read the future in their quivering entrails or to conjure up ghosts. All the satanic refinement that a perverted imagination in a state of insanity could conceive[[79]] pleased the malicious evil spirits; the more odious the monstrosity, the more assured was its efficacy. These abominable practices were sternly suppressed by the Roman government. Whereas, in the case of an astrologer who had committed an open transgression, the law was satisfied with expelling him from Rome—whither he generally soon returned,—the magician was put in the same class with murderers and poisoners, and was subjected to the very severest punishment. He was nailed to the cross or thrown to the wild beasts. Not only the practice of the profession, but even the simple fact of possessing works of sorcery made any one subject to prosecution.[[80]]
However, there are ways of reaching an agreement with the police, and in this case custom was stronger than law. The intermittent rigor of imperial edicts had no more power to destroy an inveterate superstition than the Christian polemics had to cure it. It was a recognition of its strength when state and church united to fight it. Neither reached the root of the evil, for they did not deny the reality of the power wielded by the sorcerers. As long as it was admitted that malicious spirits constantly interfered in human affairs, and that there were secret means enabling the operator to dominate those spirits or to share in their power, magic was indestructible. It appealed to too many human passions to remain unheard. If, on the one hand, the desire of penetrating the mysteries of the future, the fear of unknown misfortunes, and hope, always reviving, led the anxious masses to seek a chimerical certainty in astrology, on the other hand, in the case of magic, the blinding charm of the marvelous, the entreaties of love and ambition, the bitter desire for revenge, the fascination of crime, and the intoxication of bloodshed,—all the instincts that are not avowable and that are satisfied in the dark, took turns in practising their seductions. During the entire life of the Roman empire its existence continued, and the very mystery that it was compelled to hide in increased its prestige and almost gave it the authority of a revelation.
A curious occurrence that took place towards the end of the fifth century at Beirut, in Syria, shows how deeply even the strongest intellects of that period believed in the most atrocious practices of magic. One night some students of the famous law-school of that
city attempted to kill a slave in the circus, to aid the master in obtaining the favor of a woman who scorned him. Being reported, they had to deliver up their hidden volumes, of which those of Zoroaster and of Hostanes were found, together with those written by the astrologer Manetho. The whole city was agitated, and searches proved that many young men preferred the study of the illicit science to that of Roman law. By order of the bishop a solemn auto-da-fé was made of all this literature, in the presence of the city officials and the clergy, and the most revolting passages were read in public, "in order to acquaint everybody with the conceited and vain promises of the demons," as the pious writer of the story says.[[81]]
Thus the ancient traditions of magic continued to live in the Christian Orient after the fall of paganism. They even outlived the domination of the church. The rigorous principles of its monotheism notwithstanding, Islam became infected with those Persian superstitions. In the Occident the evil art resisted persecution and anathemas with the same obstinacy as in the Orient. It remained alive in Rome all through the fifth century,[[82]] and when scientific astrology in Europe went down with science itself, the old Mazdean dualism continued to manifest itself, during the entire Middle Ages in the ceremonies of the black mass and the worshiping of Satan, until the dawn of the modern era.
