But to return to Michelagnolo: having gone back to Florence, he lost much time now in one thing and now in another. And he made at that time for the Palace of the Medici a model for the knee-shaped windows of those rooms that are at the corner, where Giovanni da Udine adorned the chamber in stucco and painting, which is a much extolled work; and he caused to be made for them by the goldsmith Piloto, but under his own direction, those jalousies of perforated copper, which are certainly admirable things. Michelagnolo consumed many years in quarrying marbles, although it is true that while they were being excavated he made models of wax and other things for the work. But this undertaking was delayed so long, that the money assigned by the Pope for the purpose was spent on the war in Lombardy; and at the death of Leo the work was left unfinished, nothing being accomplished save the laying of a foundation in front to support it, and the transportation of a large column of marble from Carrara to the Piazza di S. Lorenzo. [Illustration: MADONNA AND CHILD (_After =Michelagnolo=. Florence: New Sacristy of S. Lorenzo_) _Anderson_] The death of Leo completely dismayed the craftsmen and the arts both in Rome and in Florence; and while Adrian VI was alive Michelagnolo gave his attention in Florence to the tomb of Julius. But after the death of Adrian Clement VII was elected, who was no less desirous than Leo and his other predecessors to leave his fame established by the arts of architecture, sculpture, and painting. At this time, which was the year 1525, Giorgio Vasari was taken as a little boy to Florence by the Cardinal of Cortona, and placed with Michelagnolo to learn art. But Michelagnolo was then summoned to Rome by Pope Clement VII, who had made a beginning with the library of S. Lorenzo and also the new sacristy, in which he proposed to place the marble tombs that he was having made for his forefathers; and he resolved that Vasari should go to work with Andrea del Sarto until he should himself be free again, and went in person to Andrea's workshop to present him.
