In spite of this arrangement, Pope Clement was allowed to employ Michelangelo in Florence or where he liked during four months of the year, that being required by his Holiness for his undertakings at S.Lorenzo.Such then was the contract made between the Duke and Michelangelo.

But here it has to be observed, that after all accounts had been made up, Michelangelo secretly agreed with the agents of his Excellency that it should be reported that he had received some thousands of crowns above what had been paid to him; the object being to make his obligation to the Duke of Urbino seem more considerable, and to discourage Pope Clement from sending him to Florence, whither he was extremely unwilling to go.
This acknowledgment was not only bruited about in words, but, without his knowledge or consent, was also inserted into the deed; not when this was drawn up, but when it was engrossed; a falsification which caused Michelangelo the utmost vexation.

The ambassador, however, persuaded him that this would do him no real harm: it did not signify, he said, whether the contract specified a thousand or twenty thousand crowns, seeing they were agreed that the tomb should be reduced to suit the sums actually received; adding, that nobody was concerned in the matter except himself, and that Michelangelo might feel safe with him on account of the understanding between them.

Upon this Michelangelo grew easy in his mind, partly because he thought he might have confidence, and partly because he wished the Pope to receive the impression I have described above.

In this way the thing was settled for the time, but it did not end there; for when he had worked his four months in Florence and came back to Rome, the Pope set him to other tasks, and ordered him to paint the wall above the altar in the Sistine Chapel.
