For a whole month Benvenuto devoted himself to this task, as we have said; but at the end of the month it was finished, and he only awaited a favorable opportunity to make his escape. He was compelled, however, to wait a few days, for the moon was near the full when the work was done. There was nothing more to be done to the nails, so Benvenuto continued to char the door, and drive the governor to desperation. That very day the functionary entered his cell more preoccupied than ever. "My dear prisoner," said the worthy man, whose mind constantly recurred to his fixed idea, "do you still propose to fly away? Come, tell me frankly." "More than ever, my dear host," replied Benvenuto. "Look you," said the governor, "you may say what you choose, but upon my word, I believe it's impossible." "Impossible, Master Georgio, impossible!" rejoined the artist; "why, you know full well that word does not exist for me, who have always exerted myself to do those things which are the most impossible for other men, and that with success. Impossible, my dear host! Why, have I not sometimes amused myself by making nature jealous, by fashioning with gold and emeralds and diamonds a flower fairer far than all the flowers that the dew empearls? Think you that he who can make flowers can not make wings?" "May God help me!" said the governor; "with your insolent assurance you'll make me lose my wits! But tell me, in order that these wings may sustain your weight in the air,--a thing which seems impossible to me, I confess,--what form shall you give them?" "I have thought deeply thereupon, as you may well imagine, since my safety depends entirely upon the shape of my wings." "With what result?" "After examining all flying things, I have concluded that, if I wish to reproduce by art what they have received from God, I can copy the bat most successfully." "But when all is said, Benvenuto," continued the governor, "even if you had the materials with which to make a pair of wings, would not your courage fail you when the time came to use them?" "Give me what I need for their construction, my dear governor, and I'll reply by flying away." "What do you need, in God's name?" "Oh! mon Dieu! almost nothing; a little forge, an anvil, files, tongs and pincers to make the springs, and twenty yards of oiled silk for the membranes. "Good! very good!" said Master Georgio; "that reassures me somewhat, for, clever as you may be, you never will succeed in obtaining all those things here." "'T is done," rejoined Benvenuto. The governor leaped from his chair; but he instantly reflected that it was a material impossibility. And yet, for all that, his poor brain had not a moment's respite. Every bird that flew by his window he imagined to be Benvenuto Cellini, so great is the influence of a master mind over one of moderate capacity. The same day Master Georgio sent for the most skilful machinist in all Rome, and ordered him to measure him for a pair of bat's wings.
