In fact, the purpose for which he had needed her must certainly come to nothing. He himself was attached to the service of Posidonius, a great magician and wizard, to whom half Alexandria flocked--Christians, Jews, and heathens--in order to communicate with the dead, with gods and with demons, to obtain spells and charms by which to attract lovers or injure foes, to learn the art of becoming invisible, or to gain a glimpse into the future. In the performance which was being planned Dada was to have appeared to a bereaved mother as the glorified presence of her lost daughter; but the disturbance in the city had driven the matron, who was rich, to take refuge in the country the previous afternoon. Nor was it likely that the sorcerer's other clients--even if all turned out better than could be hoped--would venture into the streets by night. Rich people were timid and suspicious; and as the Emperor had lately promulgated fresh and more stringent edicts against the magic arts, Posidonius had thought it prudent to postpone the meeting. Hence Medius had at present no use for the girl; but he affected to agree so readily to her wishes merely out of anxiety to relieve Isarnis as soon as possible of his uneasiness as to her fate. The morning was bright and hot, and the town was swarming with an excited mob soon after sunrise. Terror, curiosity and defiance were painted on every face; however, Medius and his young companion made their way unhindered as far as the temple of Isis by the lake. The doors of the sanctuary were closed, and guarded by soldiers; but the southern and western walls were surrounded by thousands and thousands of heathen. Some hundreds, indeed, had passed the night there in prayer, or in sheer terror of the catastrophe which could not fail to ensue, and they were kneeling in groups, groaning, weeping, and cursing, or squatting in stolid resignation, weary, crushed and hopeless. It was a heart-rending sight, and neither Dada--who till this moment had been dreading Dame Herse's scolding tongue far more than the destruction of the world--nor her companion could forbear joining in the wail that rose from this vast multitude. Medius fell on his knees groaning aloud and pulled the girl down beside him; for, upon the wall that enclosed the temple precincts, they now saw a priest who, after holding the sacred Sistrum up to view and muttering some unintelligible prayers and invocations, proceeded to address the people.
