Cellini, however, who was exacting and sensitive, became dissatisfied with the treatment of the King of France; and, leaving his workmen at his tower of the Nesle, he returned to Italy, and engaged in the service of Cosmo de' Medici, Grand Duke of Tuscany, who assigned him a house to work in.
His chief performance here was a bronze statue of Perseus for the fine square before the Palazzo Vecchio. After many drawbacks, doubts, and difficulties,—
"I now took courage, resolving to depend on myself, and banished all those thoughts which from time to time occasioned me great inquietude, and made me sorely repent my ever having quitted France. I still flattered myself that if I could but finish my statue of Perseus, all my labors would be converted to delight, and meet with a glorious and happy reward.
"This statue was intended to be of bronze, five ells in height, of one piece, and hollow. I first formed my model of clay, more slender than the statue was intended to be. I then baked it, and covered it with wax of the thickness of a finger, which I modelled into the perfect form of the statue. In order to effect in concave what the wax represented in convex, I covered the wax with clay, and baked this second covering. Thus, the wax dissolving, and escaping by fissures left open for the purpose, I obtained, between the first model and the second covering, a space for the introduction of the metal. In order to introduce the bronze without moving the first model, I placed the model in a pit dug under the furnace, and by means of pipes and apertures in the model itself, I meant to introduce the liquid metal.
"After I had made its coat of earth, covered it well, and bound it properly with irons, I began by means of a slow fire to draw off the wax, which melted away by many vent-holes,—for the more of these are made, the better the moulds are filled; and when I had entirely stripped off the wax, I made a sort of fence round my Perseus, that is, round the mould, of bricks, piling them one upon another, and leaving several vacuities for the fire to exhale at. I next began gradually to put on the wood, and kept a constant fire for two days and two nights, till, the wax being quite off and the mould well baked, I began to dig a hole to bury my mould in, and observed all those fine methods of proceeding that are proscribed by our art. When I had completely dug my hole, I took my mould, and by means of levers and strong cables directed it with care, and suspended it a cubit above the level of the furnace, so that it hung exactly in the middle of the hole. I then let it gently down to the very bottom of the furnace, and placed it with all the care and exactness I possibly could. After I had finished this part of my task I began to make a covering of the very earth I had taken off; and in proportion as I raised the earth, I made vents for it, of a sort of tubes of baked earth, generally used for conduits, and other things of a similar nature.
"I had caused my furnace to be filled with several pieces of brass and bronze, and heaped them upon one another in the manner taught us by our art, taking particular care to leave a passage for the flames, that the metal might the sooner assume its color, and dissolve into a fluid. Thus, with great alacrity, I excited my men to lay on the pine-wood, which, because of the oiliness of the resinous matter that oozes from the pine-tree and that my furnace was admirably well made, burned at such a rate that I was continually obliged to run to and fro, which greatly fatigued me. I, however, bore the hardship; but, to add to my misfortune, the shop took fire, and we were all very much afraid that the roof would fall in and crush us. From another quarter, that is, from the garden, the sky poured in so much rain and wind that it cooled my furnace.
"Thus did I continue to struggle with these cross accidents for several hours, and exerted myself to such a degree that my constitution, though robust, could no longer bear such severe hardship, and I was suddenly attacked by a most violent intermitting fever; in short, I was so ill that I found myself under a necessity of lying down upon my bed. This gave me great concern, but it was unavoidable. I thereupon addressed myself to my assistants, who were about ten in number, saying to them: 'Be careful to observe the method which I have shown you, and use all possible expedition; for the metal will soon be ready. You cannot mistake; these two worthy men here will quickly make the orifices. With two such directors you can certainly contrive to pour out the hot metal, and I have no doubt but my mould will be filled completely. I find myself extremely ill, and really believe that in a few hours this severe disorder will put an end to my life.' Thus I left them in great sorrow, and went to bed. I then ordered the maids to carry victuals and drink into the shop for all the men, and told them I did not expect to live till the next morning. In this manner did I continue for two hours in a violent fever, which I every moment perceived to increase, and I was incessantly crying out, 'I am dying, I am dying.'
"My housekeeper was one of the most sensible and affectionate women in the world. She rebuked me for giving way to vain fears, and at the same time attended me with the greatest kindness and care imaginable; however, seeing me so very ill, and terrified to such a degree, she could not contain herself, but shed a flood of tears, which she endeavored to conceal from me. Whilst we were both in this deep affliction, I perceived a man enter the room, who in his person appeared to be as crooked and distorted as a great S, and began to express himself in these terms, in a dismal and melancholy voice: 'Alas, poor Benvenuto, your work is spoiled, and the misfortune admits of no remedy.'
"No sooner had I heard the words uttered by this messenger of evil, but I cried out so loud that my voice might be heard to the skies, and got out of bed. I began immediately to dress, and, giving plenty of kicks and cuffs to the maidservants and the boy as they offered to help me on with my clothes, I complained bitterly in these terms: 'Oh, you envious and treacherous wretches, this is a piece of villany contrived on purpose; but I will sift it to the bottom, and before I die give such proofs who I am as shall not fail to astonish the whole world.' Having huddled on my clothes, I went, with a mind boding evil, to the shop, where I found all those whom I had left so alert and in such high spirits, standing in the utmost confusion and astonishment. I thereupon addressed them thus: 'Listen, all of you, to what I am going to say; and since you either would not or could not follow the method I pointed out, obey me now that I am present. My work is before us; and let none of you offer to oppose or contradict me, for such cases as this require activity and not counsel.' Hereupon one of them had the assurance to say to me, 'Look you, Benvenuto, you have undertaken a work which our art cannot compass, and which is not to be effected by human power.'
