The Duke having then returned to his state, Girolamo also returned, and was retained by him and employed as architect in restoring an old palace on the Monte dell'Imperiale, above Pesaro, and adding to it another tower. That palace was adorned with scenes in painting from the actions of the Duke, after the directions and designs of Girolamo, by Francesco da Forli and Raffaello dal Borgo, painters of good repute, and by Camillo Mantovano, a very rare master in painting landscapes and verdure; and the young Florentine Bronzino also worked there, among others, as has been related in the Life of Pontormo. Thither, likewise, were summoned the Dossi of Ferrara, and a room was assigned to them to paint; but since, when they had finished that room, it did not please the Duke, he had it thrown down and repainted by the masters mentioned above. Girolamo then erected the tower there, one hundred and twenty feet in height, with thirteen flights of wooden steps whereby to ascend to the top, so well fitted and concealed in the walls, that they can be withdrawn with ease from story to story, which renders that tower very strong and marvellous. A desire afterwards came to the Duke to fortify Pesaro, and he caused Pier Francesco da Viterbo, a most excellent architect, to be sent for; and Girolamo always taking part in the discussions that arose about the fortifications, his discourse and his opinions were held to be good and full of judgment. Wherefore, if I may be allowed to say it, the design of that fortress came rather from Girolamo than from any other, although that sort of architecture was always little esteemed by him, appearing to him to be of small value and dignity. The Duke, then, perceiving how rare a genius he had at his command, determined to build on the above-named Monte dell'Imperiale, near the old palace, a new palace; and so he built that to be seen there at the present day, which being a very beautiful and well-planned fabric, and full of apartments, colonnades, courts, loggie, fountains, and most delightful gardens, there is no Prince passes that way that does not go to see it. Wherefore it was right fitting that Pope Paul III, on his way to Bologna with all his Court, should go to see it and find it entirely to his satisfaction. From the design of this same master, the Duke caused the Palace at Pesaro to be restored, and also the little park, making within it a house representing a ruin, which is a very beautiful thing to see. Among other things, there is a staircase similar to that of the Belvedere in Rome, which is very handsome. By means of him the Duke had the fortress of Gradara restored, and likewise the Palace at Castel Durante, insomuch that all that is good in those works came from that admirable genius. Girolamo also built the corridor of the Palace at Urbino, above the garden, and he enclosed a courtyard on one side with perforated stone-work executed with great diligence.
