The Pope was induced by an enemy of Benvenuto, the Cardinal Salviati, to send for a rival goldsmith, Tobbia, to come to Rome. On his arrival both were summoned into the Pope's presence. "He then commanded each of us to draw a design for setting a unicorn's horn, the most beautiful that ever was seen, which had cost 17,000 ducats. As the Pope proposed making a present of it to King Francis, he chose to have it first richly adorned with gold; so he employed us to draw the designs. When we had finished them we carried them to the Pope. Tobbia's design was in the form of a candlestick; the horn was to enter it like a candle, and at the bottom of the candlestick he had represented four little unicorns' heads,--a most simple invention. As soon as I saw it, I could not contain myself so as to avoid smiling at the oddity of the conceit. The Pope, perceiving this, said, 'Let me see that design of yours.' It was the single head of a unicorn, fitted to receive the horn. I had made the most beautiful sort of head conceivable, for I drew it partly in the form of a horse's head, and partly in that of a hart's, adorned with the finest sort of wreaths and other devices; so that no sooner was my design seen but the whole Court gave it the preference." * * * * * Benvenuto continued to make many beautiful things for Pope Clement VII. up to the time of his death. That Pope was succeeded in the papal chair by Cardinal Farnese (Paul III.), on the 13th of October, 1534. "I had formed a resolution to set out for France, as well because I perceived that the Pope's favor was withdrawn from me by means of slanderers who misrepresented my services, as for fear that those of my enemies who had most influence might still do me some greater injury. For these reasons I was desirous to remove to some other country, and see whether fortune would there prove more favorable to me. Leaving Rome, I bent my course to Florence, whence I travelled on to Bologna, Venice, and Padua." He reached Paris, with two workmen whom he took with him from Rome, "without meeting any ill accident, and travelling on in uninterrupted mirth." But being dissatisfied with his reception there, he returned instantly to Rome, where his fears were realized; for he was arrested by order of the Pope, and made a prisoner in the Castle of St. Angelo. "This was the first time I ever knew the inside of a prison, and I was then in my thirty-seventh year. The constable of the Castle of St. Angelo was a countryman of mine, a Florentine, named Signor Giorgio Ugolini. This worthy gentleman behaved to me with the greatest politeness, permitting me to walk freely about the castle on my parole of honor, and for no other reason but because he saw the severity and injustice of my treatment.
