From that time until the year 1550, when Julius III was elected Pope, Taddeo occupied himself with works of no great importance, yet with considerable profits. In which year of 1550, the year of the Jubilee, Ottaviano, the father of Taddeo, with his mother and another of their sons, went to Rome to take part in that most holy Jubilee, and partly, also, to see their son. After they had been there some weeks with Taddeo, on departing they left with him the boy that they had brought with them, who was called Federigo, to the end that he might cause him to study letters. But Taddeo judged him to be more fitted for painting, as indeed Federigo has since been seen to be from the excellent result that he has achieved; and so, after he had learned his first letters, Taddeo began to make him give his attention to design, with better fortune and support than he himself had enjoyed. Meanwhile Taddeo painted in the Church of S. Ambrogio de' Milanesi, on the wall of the high-altar, four stories of the life of that Saint, coloured in fresco and not very large, with a frieze of little boys, and women after the manner of terminal figures; which was a work of no little beauty. That finished, he painted a facade full of stories of Alexander the Great, beside S. Lucia della Tinta, near the Orso, beginning from his birth and continuing with five stories of the most noteworthy actions of that famous man; which work won him much praise, although it had to bear comparison with another facade near it by the hand of Polidoro. About that time Guidobaldo, Duke of Urbino, having heard the fame of the young man, who was his vassal, and desiring to give completion to the walls of the chapel in the Duomo of Urbino, wherein Battista Franco, as has been related, had painted the vaulting in fresco, caused Taddeo to be summoned to Urbino. And he, leaving Federigo in Rome, under the care of persons who might make him give his attention to his studies, and likewise another of his brothers, whom he placed with some friends to learn the goldsmith's art, went off to Urbino, where many attentions were paid him by that Duke; and then orders were given to him as to all that he was to design in the matter of the chapel and other works. But in the meantime the Duke, as General to the Signori of Venice, had to visit Verona and the other fortified places of that dominion, and he took with him Taddeo, who copied for him the picture by the hand of Raffaello da Urbino which, as has been related in another place, is in the house of the noble Counts of Canossa. And he afterwards began, also for his Excellency, a large canvas with the Conversion of S. Paul, which, unfinished as he left it, is still in the possession of his father Ottaviano at Sant'Agnolo.
