Subsequently, I was employed to erect two pulpits in the choir of St. Maria del Fiore, and adorn them with historical figures in basso-relievo of bronze, together with varieties of other embellishments. About this period, the great block of marble, intended for the gigantic statue of Neptune, to be placed near the fountain on the Ducal Piazza, was brought up the River Arno, and thence by road to Florence. A competition took place between the model which I had made for the statue of Neptune and that designed by Bandinello. The duchess, who had become my implacable enemy, favoured Bandinello, and I waited upon her, carrying to her some pretty trifles of my making, which her excellency liked very much. Then I added that I had undertaken one of the most laborious tasks in the world—the carving of a Christ crucified, of the whitest marble, upon a cross of the blackest, and as large as the life. Upon her asking me what I proposed doing with it, I said I would freely make her a present of it; that all I desired was that she would be neutral with respect to the model of the Neptune which the duke had ordered to be made.
When I had finished the model of Neptune, the duke came to see it. It gave him high satisfaction, and he said I deserved the prize. Some weeks later, Bandinello died, and it was generally thought that the grief which he felt at losing the fine piece of marble out of which the statue of Neptune was to be made greatly contributed to hasten his dissolution. When I was working at my great model of Neptune, I was seized with illness, caused by a dose of sublimate poison administered in food by a man named Sbietta and his brother, a profligate priest, from whom I had bought the annuity of a farm. Upon my recovery the duke and the duchess came unexpectedly with a grand retinue to my workshop to see the image of Christ upon the Cross, and it pleased them so greatly that they bestowed the highest encomiums on me. Though I had undergone infinite labour in its execution, yet with pleasure I made them a present of it, thinking none more worthy of that fine piece of work than their excellencies. They talked a long time in praise of my abilities, and the duchess seemed, as it were, to ask pardon for her past treatment of me.
At this juncture the Queen Dowager of France, Catherine de Medici, dispatched Signor Baccio del Bene on a mission to our duke. The signor and I were intimate friends, and he told me that the queen had a strong desire to finish the sepulchral monument to her husband, King Henry, and if I chose to return to France and again take possession of my castle, I should be supplied with whatever I wanted, in case I was willing to serve her majesty. But when this was communicated to the duke, his excellency said he meant to keep me in his own service; and the Queen of France, who had received a loan of money from the duke, did not propose the thing any more for fear of offending him; so I was obliged to stay, much against my will.
