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 {193} 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-fe 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]
