Melissa started at hearing the order to halt shouted from the Serapeum, far down the road, and again, close at hand, "Halt!" The procession came to a standstill, the riders drew rein, the blue wheels ceased to turn, the coach was immovable but a few steps in front of her, and her eyes met those of the old man. The thought flashed through her brain that Fate itself had brought about this pause just at this spot; and when she heard the mosaic-worker exclaim, "The great Roman physician!" horses, coach, and everything swam before her eyes; she snatched her hand away from that of Andreas, and stepped out on the roadway. In an instant she was standing face to face with the venerable leech. She heard the warning voice of her companion, she saw the crowd staring at her, she had, no doubt, a brief struggle with her maidenly shyness, but she carried out her purpose. The thought that the gods themselves were helping her to appeal to the only man who could save her lover, encouraged her to defy every obstacle. She was standing by the vehicle; and scarcely had she raised her sweet, innocent, blushing face with pathetic and touching entreaty to the white- haired Roman, her large, tear-filled eyes meeting his, when he beckoned her to him, and in pleasant, sympathetic tones desired to know what she wanted. Then she made bold to ask whether he were the great Roman physician, and he replied with a flattered and kindly smile that he was sometimes so called. Her thankful glance to heaven revealed what a comfort his words were, and now her rosy lips moved freely, and she hurriedly, but with growing courage, gave him to understand that her betrothed, the son of a respected Roman citizen of Alexandria, was lying badly wounded in the head by a stone, and that the leech who was treating him had said that none but he, the great Galenus, could save the young man's life. She also explained that Ptolemaeus, though he had said that Diodoros needed quiet above all things, had proposed to carry him to the Serapeum, and to commend him there to the care of his greater colleague, but that she feared the worst results from the move. She glanced pleadingly into the Roman's eyes, and added that he looked so kind that she hoped that he would go instead to see the sufferer, who had, quite by chance, been taken into a Christian house not very far from the Serapeum, where he was being taken good care of, and--as a matter of course--cure her lover.
