Benvenuto Cellini (15001571). Autobiography. The Harvard Classics. 190914.
ON the following day, when the servant of the castellan who was my friend brought me my food, I gave him this sonnet copied out in writing. Without informing the other ill-disposed servants who were my enemies, he handed it to the castellan. At that time this worthy man would gladly have granted me my liberty, because he fancied that the great wrong done to me was a main cause of his death. He took the sonnet, and having read it more than once, exclaimed: These are neither the words nor the thoughts of a madman, but rather of a sound and worthy fellow. Without delay he ordered his secretary to take it to the Pope, and place it in his own hands, adding a request for my deliverance.
While the secretary was on his way with my sonnet to the Pope, the castellan sent me lights for day and night, together with all the conveniences one could wish for in that place. The result of this was that I began to recover from my physical depression, which had reached a very serious degree.
The Pope read the sonnet several times. Then he sent word to the castellan that he meant presently to do what would be pleasing to him. Certainly the Pope had no unwillingness to release me then; but Signor Pier Luigi, his son, as it were in the Popes despite, kept me there by force.
The death of the castellan was drawing near; and while I was engaged in drawing and modelling that miracle which I had seen, upon the morning of All Saints day he sent his nephew, Piero Ugolini, to show me certain jewels. No sooner had I set eyes on them than I exclaimed: This is the countersign of my deliverance! Then the young man, who was not a person of much intelligence, began to say: Never think of that, Benvenuto! I replied: Take your gems away, for I am so treated here that I have no light to see by except what this murky cavern gives, and that is not enough to test the quality of precious stones. But, as regards my deliverance from this dungeon, the day will not end before you come to fetch me out. It shall and must be so, and you will not be able to prevent it. The man departed, and had me locked in; but after he had remained away two hours by the clock, he returned without armed men, bringing only a couple of lads to assist my movements; so after this fashion he conducted me to the spacious rooms which I had previously occupied (that is to say, in 1538), where I obtained all the conveniences I asked for.
