"There is enough for two," said he, "in the phial; and we will put this thing to the test. But if you speak or move or make any sign, forthwith in that moment you shall die." Then the Duke poured half the contents of the phial into a glass and came to Lorenzo and whispered to him, "If the drug works on him, and the wizard is proved to lie, the wizard shall die; but we will carry Antonio with us; and when I have mustered my Guard, I will hang him in the square as I have sworn. But if the drug does not work, then we must kill him here; for I fear to carry him against his will; for he is a wonderful man, full of resource, and the people also love him. Therefore, if the operation of the drug fail, run him through with your sword when I give the signal." Now Antonio was recovering from his swoon, and he overheard part of what the Duke said, but not all. As to the death of the wizard he did not hear, but he understood that the Duke was about to test the effect of the drug on him, and that if it had no effect, he was to die; whereas, if its operation proved sufficient, he should go alive; and he saw here a chance for his life in case what the wizard had said should prove true. "Drink, Antonio," said the Duke softly. "No harm comes to you. Drink: it is a refreshing draught." And Antonio drank the draught, the wizard looking on with parted lips and with great drops of sweat running from his forehead and thence down his cheeks to his mouth, so that his lips were salt when he licked them. And the Duke, having seen that Lorenzo had his sword ready for Antonio, took his stand by the wizard with the dagger from his belt in his hand. And he cried to Antonio, "Rise." And Antonio rose up. The wizard started a step towards him; but the Duke showed his dagger, and said to Antonio, "Will you go with me to Firmola, Antonio?" And Antonio answered, "I will go." "Do you love me, Antonio?" asked the Duke. "Aye, my lord," answered Antonio. "Yet you have done many wicked things against me." "True, my lord," said Antonio. "Is your mind then changed?" "It is, my lord," said Antonio. "Then leap two paces into the air," said the Duke; and Antonio straightway obeyed. "Go down on your knees and crawl;" and Antonio crawled, smiling secretly to himself. Then the Duke bade Lorenzo mount Antonio on his horse; and he commanded the wizard to follow him; and they all went out where the horses were; and the three mounted, and the wizard followed; and they came to the end of the bridge. There the Duke turned sharp round and rode by the side of the rushing river. And, suddenly pausing, he said to Antonio, "Commend thy soul to God and leap in." And Antonio commended his soul to God, and would have leapt in; but the Duke caught him by the arm even as he set spurs to his horse, saying, "Do not leap." And Antonio stayed his leap. Then the Duke turned his face on the wizard, saying, "The potion works, wizard. Why did you lie?"
