During this conversation the alarm which had come over Melissa at Caesar's silence had entirely disappeared. The despot whose suffering had appealed to her sympathetic soul, now struck her as singular rather than terrible. The idea that she, the humble artist's daughter, could harbor the soul of a Persian princess, amused her; and when the lion lifted his head and lashed the floor with his tail at her approach, she felt that she had won his approbation. Moved by a sudden impulse, she laid her hand on his head and boldly stroked it. The light, warm touch soothed the fettered prince of the desert, and, rubbing his brow against Melissa's round arm, he muttered a low, contented growl. At this Caesar was enchanted; it was to him a further proof of his strange fancy. The "Sword of Persia" was rarely so friendly to any one; and Theocritus owed much of the favor shown him by Caracalla to the fact that at their first meeting the lion had been on particularly good terms with him. Still, the brute had never shown so much liking for any stranger as for this young girl, and never responded with such eager swinging of his tail excepting to Caesar's own endearments. It must be instinct which had revealed to the beast the old and singular bond which linked his master and this new acquaintance. Caracalla, who, in all that happened to him, traced the hand of a superior power, pointed this out to Philostratus, and asked him whether, perhaps, the attack of pain he had just suffered might not have yielded so quickly to the presence of the revived Roxana rather than to Galen's pills. Philostratus thought it wise not to dispute this assumption, and soon diverted the conversation to the subject of Melissa's imprisoned relations. He quietly represented to Caracalla that his noblest task must be to satisfy the spirit of her who had been so dear to the hero whose life he was to fulfill; and Caesar, who was delighted that the philosopher should recognize as a fact the illusion which flattered him, at once agreed. He questioned Melissa about her brother Alexander with a gentleness of which few would have thought him capable; and the sound of her voice, as she answered him modestly but frankly and with sisterly affection, pleased him so well that he allowed her to speak without interruption longer than was his wont. Finally, he promised her that he would question the painter, and, if possible, be gracious to him. He again clapped his hands, and ordered a freedman named Epagathos, who was one of his favorite body-servants, to send immediately for Alexander from the prison. As before, when Adventus had been summoned, a crowd followed Epagathos, and, as Caesar did not dismiss them, Melissa was about to withdraw; the despot, however, desired her to wait.
