AFTER I had let my statue cool for two whole days, I began to uncover it by slow degrees. The first thing I found was that the head of Medusa had come out most admirably, thanks to the air-vents; for, as I had told the Duke, it is the nature of fire to ascend. Upon advancing farther, I discovered that the other head, that, namely, of Perseus, had succeeded no less admirably; and this astonished me far more, because it is at a considerably lower level than that of the Medusa. Now the mouths of the mould were placed above the head of Perseus and behind his shoulders; and I found that all the bronze my furnace contained had been exhausted in the head of this figure. It was a miracle to observe that not one fragment remained in the orifice of the channel, and that nothing was wanting to the statue. In my great astonishment I seemed to see in this the hand of God arranging and controlling all.
I went on uncovering the statue with success, and ascertained that everything had come out in perfect order, until I reached the foot of the right leg on which the statue rests. There the heel itself was formed, and going farther, I found the foot apparently complete. This gave me great joy on the one side, but was half unwelcome to me on the other, merely because I had told the Duke that it could not come out. However, when I reached the end, it appeared that the toes and a little piece above them were unfinished, so that about half the foot was wanting. Although I knew that this would add a trifle to my labour, I was very well pleased, because I could now prove to the Duke how well I understood my business. It is true that far more of the foot than I expected had been perfectly formed; the reason of this was that, from causes I have recently described, the bronze was hotter than our rules of art prescribe; also that I had been obliged to supplement the alloy with my pewter cups and platters, which no one else, I think, had ever done before.
Having now ascertained how successfully my work had been accomplished, I lost no time in hurrying to Pisa, where I found the Duke. He gave me a most gracious reception, as did also the Duchess; and although the majordomo had informed them of the whole proceedings, their Excellencies deemed my performance far more stupendous and astonishing when they heard the tale from my own mouth. When I arrived at the foot of Perseus, and said it had not come out perfect, just as I previously warned his Excellency, I saw an expression of wonder pass over his face, while he related to the Duchess how I had predicted this beforehand. Observing the princes to be so well disposed towards me, I begged leave from the Duke to go to Rome. He granted it in most obliging terms, and bade me return as soon as possible to complete his Perseus; giving me letters of recommendation meanwhile to his ambassador, Averardo Serristori. We were then in the first years of Pope Giulio de Monti.1
