Then Count Antonio, who believed no more than the Duke what the wizard had said concerning the need of his own presence for the working of the drug, was very sorely put to it to stay quietly where he was; for if the Duke rode away now with the phial, he might well find means to give it to the Lady Lucia before any warning could be conveyed to her. And, although the danger was great, yet his love for Lucia and his fear for her overcame his prudence, and suddenly he sprang from behind the mirror, drawing his sword and crying, "Give me that drug, my lord, or your life must answer for it." But fortune served him ill; for as the Duke and Lorenzo shrank back at his sudden appearance, and he was about to spring on them, behold, his foot caught in the folds of the black cloth that had been over the mirror and now lay on the ground, and, falling forward, he struck his head on the marble rim that ran round the charcoal stove, and, having fallen with great force, lay there like a man dead. With loud cries of triumph, the Duke and Lorenzo, having drawn their swords, ran upon him; and the Duke planted his foot upon his neck, crying, "Heaven sends a greater prize! At last, at last I have him! Bind his hands, Lorenzo." Lorenzo bound Antonio's hands as he lay there, a log for stillness. The Duke turned to the wizard and a smile bent his lips. "O faithful subject and servant!" said he. "Well do you requite my mercy and forbearance, by harbouring my bitterest enemies and suffering them to hear my secret counsels. Had not Antonio chanced to trip, it is like enough he would have slain Lorenzo and me also. What shall be your reward, O faithful servant?" When the Wizard of Baratesta beheld the look that was on Duke Valentine's face, he suddenly cried aloud, "The mirror, the mirror!" and sank in a heap on the floor, trembling in every limb; for he remembered the aspect of his own face in the mirror and knew that the hour of his death had come. And he feared mightily to die; therefore he besought the Duke very piteously, and told him again that from his hand alone could the drug receive its potency. And so earnest was he in this, that at last he half-won upon the Duke, so that the Duke wavered. And as he doubted, his eye fell on Antonio; and he perceived that Antonio was recovering from his swoon.
