Under Pope Clement VII. he took part in the defence of the Castle of St. Angelo, when it was besieged by the Constable de Bourbon, and the Pope reposed such confidence in Cellini that he was entrusted with the task of removing all the gems in the treasury from their settings, and concealing the stones in the thick folds of his clothing. However, I am not going to enlarge on Benvenuto's many talents, but to tell you of a wonderful adventure which befell him in the very Castle of St. Angelo he had helped to defend.

Those were lawless days, and Cellini was a man of fiery temper, to whom blows came more naturally than patience and forbearance. So it came to pass that, being told that a certain goldsmith named Pompeo had been spreading false reports about him, Benvenuto fell upon him one fine day in the very midst of Rome, and promptly stabbed him to death.

This might possibly have been overlooked, but a workman, jealous of Cellini's success and reputation, accused the artist to the reigning Pope, Paul III., of having purloined some of the jewels entrusted to his care during the siege, and Paul was not to be trifled with where the affairs of the treasury were concerned. Moreover, a near relation of the Pope's was Cellini's sworn enemy, and this sufficed to seal his fate.

So, when taking a walk one morning, Benvenuto suddenly found himself face to face with Crespino, the sheriff, attended by his band of constables. Crespino advanced, saying, 'You are the Pope's prisoner.'

'Crespino,' exclaimed Benvenuto, 'you must take me for some one else.'

'No, no,' replied Crespino, 'I know you perfectly, Benvenuto, and I have orders to carry you to the Castle of St. Angelo, where great nobles and men of talent like yourself are sent.'

Then he politely begged Benvenuto to give up his sword, and led him off to the Castle, where he was locked up in a room above the keep.

It was easy enough for Benvenuto to refute the accusations brought against him; nevertheless he was kept prisoner, in spite of the intervention of the French ambassador, who demanded his liberty in the name of Francis I.

The governor of the Castle was, like Cellini, a Florentine, and at first showed himself full of kind attentions towards his countryman, allowing him a certain amount of liberty on parole, within the Castle walls. Growing suspicious later, he kept his prisoner closer, but after a time he restored him to comparative liberty.

When Benvenuto found how changeable the governor's humour was, he set himself to think over matters seriously. 'For,' he reflected, 'should a fresh fit of anger or suspicion cause him to confine me more strictly, I should feel myself released from my word, and it may be as well to be prepared.'

Accordingly he ordered some new coarse linen sheets to be brought him, but when soiled he did not send them back. When his servants asked for the sheets so as to have them washed he bade them say no more, as he had given them to one of the poor soldiers on guard, who would be sure to get into trouble if the matter were known. By degrees he emptied the straw out of his mattress, burning a little of it at a time in his fireplace, and replacing it with the sheets, which he cut into strips some inches wide. As soon as he thought these strips were long enough for his purpose, he told his servants that he had given all the sheets away, and that in future they had better bring him finer linen, which he would be sure to return.

Now it so happened that every year the governor was subject to a most distressing illness, which, for the time being, entirely deprived him of his reason. When it began to come on, he would talk and chatter incessantly. Each year he had some fresh hallucination, at one time fancying himself an oil-jar, at another a frog, and skipping about like one. Again, another time, he declared he was dead, and wished to be buried; and so, year by year, he was the victim of some new delusion. This year he imagined he was a bat, and as he walked about he uttered little half-smothered cries like a bat, and flapped his hands and moved his body as though about to fly. His faithful old servants and his doctors noticed this, and, thinking change of ideas and variety of conversation might do him good, they frequently fetched Benvenuto to entertain him.

One day the governor asked Benvenuto whether it had ever occurred to him to desire to fly, and; on being answered in the affirmative, he inquired further how he should set about it.

Benvenuto replied that the only flying creature it would be at all possible to imitate artificially was the bat, on which the poor man cried out, 'True, true, that's it, that's the thing.' Then turning round he said, 'Benvenuto, if you had everything you required for it, do you think you could fly?'

'Oh, yes,' said the artist; 'if you will only leave me free to do it, I will engage to make a pair of wings of fine waxed cloth, and to fly from here to Prati with them.'

'And I, too,' exclaimed the governor; 'I could do it too, but the Pope has ordered me to keep you like the apple of his eye, and as I strongly suspect you're a cunning fellow, I shall lock you well up and give you no chance of flying.'

Thereupon, and in spite of all Benvenuto's entreaties and protestations, the governor ordered him to be taken back to prison and more carefully guarded than ever.

Seeing he could not help himself, Cellini exclaimed before the officers and attendants: 'Very well! lock me up and keep me safe, for I give you due warning I mean to escape in spite of everything.'

No sooner was he shut up in his cell than he fell to turning over in his mind how this escape could be made, and began minutely examining his prison, and, after discovering what he thought would be a sure way of getting out, he considered how best he might let himself down from the top of this enormous donjon tower, which went by the name of 'Il Mastio.' He began by measuring the length of the linen strips, which he had cut and joined firmly together so as to form a sort of rope, and he thought there would be enough for his purpose. Next, he armed himself with a pair of pincers which he had taken from one of his guards who was fond of carpentering, and who, amongst his tools, had a particularly large and strong pair of pincers, which appeared so useful to Benvenuto that he abstracted them, and hid them in his mattress.

As soon as he thought himself safe from interruption, he began to feel about for the nails in the ironwork of the door, but owing to its immense thickness they were by no means easy to get at. However, he managed at length to extract the first nail. Then came the question, how to conceal the hole left behind. This he contrived by making a paste of rusty scrapings and wax, which he modelled into an exact representation of the head of a nail, and in this way he replaced each nail he drew by a facsimile of its head in wax.

Great care was required to leave just a sufficient number of nails to keep the ironwork and hinges in their places. But Benvenuto managed this by first drawing the nails, cutting them as short as he dared, and then replacing them in such a way as to keep things together, and yet to allow of their being easily drawn out at the last moment.

All this was by no means easy to contrive, for the governor was constantly sending some one to make sure that his prisoner was safe.

The two men who were specially charged with this duty were rough and rude, and one of them in particular took pains to inspect the whole room carefully every evening, paying special attention to the locks and hinges.

Cellini lived in constant terror lest it should occur to them to examine his bedding, where, besides the pincers, he had hidden a long sharp dagger and some other instruments, as well as his long strips of linen. Each morning he swept out and dusted his room and carefully made his bed, ornamenting it with flowers which he got the soldier from whom he had taken the pincers to bring him. When his two warders appeared he desired them on no account to go near or touch his bed, for fear of soiling or disturbing it. Sometimes, in order to tease him, they would touch it, and then he would shout: 'Ah! you dirty rascals! Just let me get at one of your swords and see how I'll punish you! How dare you touch the bed of such a man as I am? Little care I about risking my own life, for I should be certain to take yours. Leave me in peace with my grief and trouble, or I will show you what a man can do when driven to desperation!'

These words were repeated to the governor, who forbade the gaolers touching Cellini's bed, or entering his room armed. The bed once safe, he felt as if all else must go right.

One night the governor had a worse attack than ever, and in a fit of madness kept repeating that he certainly was a bat, and that, should they hear of Benvenuto's escape, they must let him fly off too, as he was sure he could fly better at night and would overtake the fugitive. 'Benvenuto,' said he, 'is but a sham bat, but as I am a real bat, and he has been given into my keeping, I shall soon catch him again, depend on it.'

This bad attack lasted several nights, and the Savoyard soldier, who took an interest in Benvenuto, reported to him that the servants were quite worn out watching their sick master. Hearing this, Cellini resolved to attempt his escape at once, and set hard to work to complete his preparations. He worked all night, and about two hours before dawn he, with much care and trouble, removed the hinges from the door. The casing and bolts prevented his opening it wide, so he chipped away the woodwork, till at length he was able to slip through, taking with him his linen ropes, which he had wound on two pieces of wood like two great reels of thread.

Having passed the door he turned to the right of the tower, and having removed a couple of tiles, he easily got out on the roof. He wore a white doublet and breeches and white boots, into one of which he had slipped his dagger. Taking one end of his linen rope, he now proceeded to hook it carefully over an antique piece of tile which was firmly cemented into the wall. This tile projected barely four fingers' breadth, and the band hooked over it as on a stirrup. When he had made it firm he prayed thus: 'O Lord, my God, come now to my aid, for Thou knowest that my cause is righteous, and that I am aiding myself.' Then he gently let himself slide down the rope till he reached the ground. There was no moon, but the sky was clear, and once down he gazed up at the tower from which he had made so bold a descent, and went off in high spirits, thinking himself at liberty, which indeed was by no means the case.

On this side of the Castle the governor had had two high walls built to inclose his stables and his poultry-yard, and these walls had gates securely bolted and barred on the outside.

In despair at these obstacles Benvenuto roamed about at random, cursing his bad luck, when suddenly he hit his foot against a long pole which lay hidden in the straw. With a good deal of effort he managed to raise it against the wall and to scramble up to the top. Here he found a sharply sloping coping stone which made it impossible to draw the pole up after him, but he fastened a portion of the second linen band to it, and by this means let himself down as he had done outside the donjon tower.

By this time Benvenuto was much exhausted, and his hands were all cut and bleeding; however, after a short rest he climbed the last inclosure, and was just in the act of fastening his rope to a battlement, when, to his horror, he saw a sentinel close to him. Desperate at this interruption, and at the thought of the risk he ran, he prepared to attack the sentry, who, however, seeing a man advance on him with a drawn dagger and determined air, promptly took to his heels, and Benvenuto returned to his rope. Another guard was near, but, hoping not to have been observed, the fugitive secured his band and hastily slid down it. Whether it was fatigue, or that he thought himself nearer the ground than he really was, it is impossible to say, but he loosened his hold, and fell, hitting his head, and lay stretched on the ground for more than an hour.

The sharp freshness of the air just before sunrise revived him, but his memory did not return immediately, and he fancied his head had been cut off and that he was in purgatory. By degrees, as his senses returned, he realised that he was no longer in the Castle, and remembered what he had done. He put his hands to his head and withdrew them covered with blood, but on carefully examining himself he found he had no serious wound, though on attempting to move he discovered that his right leg was broken. Nothing daunted, he drew from his boot his poniard with its sheath, which had a large ball at the end; the pressure of this ball on the bone had caused the fracture. He threw away the sheath, and cutting off a piece of the remaining linen band with his dagger, he bound up his leg as best he could, and then, dagger in hand, proceeded to drag himself along on his knees towards the gate of the town. It was still closed, but seeing one stone near the bottom, which did not look very huge, he tried to displace it. After repeated efforts it shook, and at length yielded to his efforts, so, forcing it out, he squeezed himself through.

He had barely entered Rome when he was attacked by a band of savage dogs, who bit and worried him cruelly. He fought desperately with his dagger, and gave one dog such a stab that it fled howling, followed by the rest of the pack, leaving Benvenuto free to drag himself as best he could towards St. Peter's.

By this time it was broad daylight, and there was much risk of discovery; so, seeing a water-carrier passing with his train of asses laden with jars full of water, Benvenuto hailed him and begged he would carry him as far as the steps of St. Peter's.

'I am a poor fellow,' said he, 'who have broken my leg trying to get out of the window of a house where I went to see my lady-love. As the house belongs to a great family, I much fear I shall be cut to pieces if I am found here; so pray help me off and you shall have a gold crown for your pains,' and Benvenuto put his hand to his purse, which was well filled.

The water-carrier readily consented, and carried him to St. Peter's, where he left him on the steps, from whence Benvenuto began to crawl towards the palace of Duke Ottavio, whose wife, a daughter of the emperor's, had brought many of Cellini's friends from Florence to Rome in her train. She was well disposed towards the great artist, and he felt that beneath her roof he would be in safety. Unluckily, as he struggled along, he was seen and recognised by a servant of Cardinal Cornaro's, who had apartments in the Vatican. The man hurried to his master's room, woke him up, and cried: 'Most reverend lord, Benvenuto is below; he must have escaped from the Castle, and is all bleeding and wounded. He appears to have broken his leg, and we have no idea where he is going.'

'Run at once,' exclaimed the Cardinal, 'and fetch him here, to my room.'

When Benvenuto appeared the Cardinal assured him he need have no fears, and sent off for the first surgeons in Rome to attend to him. Then he shut him up in a secret room, and went off to try and obtain his pardon from the Pope.

Meantime a great commotion arose in Rome, for the linen ropes dangling from the great tower had attracted notice, and all the town was running out to see the strange sight. At the Vatican Cardinal Cornaro met a friend, to whom he related all the details of Benvenuto's escape, and how he was at that very moment hidden in a secret chamber. Then they both went to the Pope, who, as they threw themselves at his feet, cried, 'I know what you want with me.'

'Holy Father,' said the Cardinal's friend, 'we entreat you to grant us the life of this poor man. His genius deserves some consideration; and he has just shown an almost superhuman amount of courage and dexterity. We do not know what may be the crimes for which your Holiness has seen fit to imprison him, but if they are pardonable we implore you to forgive him.'

The Pope, looking somewhat abashed, replied that he had imprisoned Benvenuto for being too presumptuous; 'however,' he added, 'I am well aware of his talents and am anxious to keep him near me, and am resolved to treat him so well that he shall have no desire to return to France. I am sorry he is ill; bid him recover quickly, and we will make him forget his past sufferings.'

I am sorry to say the Pope was not so good as his words, for Benvenuto's enemies plotted against him, and after a time he was once more shut up in his former prison, from which, however, he was eventually delivered at the urgent request of the King of France, who warmly welcomed the great artist to his Court, where he spent some years in high honour.
