Then, he remembered, too, to what a position he had risen through that master's confidence in him. Polybius knew nothing of the concerns of his house but from the reports laid before him by Andreas; for the steward controlled not merely the estate but the fortune of the family, and for years had been at the head of the bank which he himself had founded to increase the already vast income of the man to whom he owed his freedom. Polybius paid him a considerable portion of each year's profits, and had said one day at a banquet, with the epigrammatic wit of an Alexandrian, that his freedman, Andreas, served his interests as only one other man could do--namely, himself--but with the industry of ten. The Christian greatly appreciated his confidence; and as he walked on by the side of Melissa, he told himself again and again that it would be dishonorable to betray it. If only the sweet girl might find the way alone! If she were chosen to salvation, the Lord himself would lead and guide her. Had he indeed not beckoned her already by impressing on her heart those words, "The fullness of the time is now come?" That he was justified in keeping this remembrance alive he had no doubt; and he was about to speak of it again, when she prevented him by raising her large eyes beseechingly to his, and asking him: "Is Diodoros in real danger? Tell me the truth. I would rather endure the worst than this dreadful anxiety." So Andreas acknowledged that the youth was in a bad way, but that Ptolemaeus, himself well-skilled, hoped to cure him if his greater colleague Galenus would aid him. "And it is to secure his assistance, then," Melissa went on, "that the leech would have him carried to the Serapeum?" "Yes, my child. For he is in Caesar's train, and it would be vain to try to speak with him to-day or to-morrow." "But the journey through the town will do the sufferer a mischief." "He will be carried in a litter." "But even that is not good for him. Perfect quiet, Ptolemaeus said, was the best medicine." "But Galenus has even better remedies at hand," was the reply. Melissa seemed satisfied with this assurance, for she walked on for some time in silence. But when the uproar of the crowd in the vicinity of the Serapeum became more audible as they advanced, she suddenly stood still, and said: "Come what may, I will find my way to the great physician's presence and crave his help." "You?" cried the freedman; and when she firmly reiterated her purpose, the strong man turned pale. "You know not what you say!" he exclaimed, in deep concern. "The men who guard the approaches to Caracalla are ruthless profligates, devoid of courtesy or conscience. But, you may rely upon it, you will not even get into the antechamber." "Perhaps. Nevertheless, it is my duty, and I will try."
