Light is thrown upon these dissensions between Michelangelo and his proposed assistants by a letter which Jacopo Sansovino wrote to him at Carrara, on the 30th of June 1517. He betrays his animus at the commencement by praising Baccio Bandinelli, to mention whom in the same breath with Buonarroti was an insult. Then he proceeds: "The Pope, the Cardinal, and Jacopo Salviati are men who when they say yes, it is a written contract, inasmuch as they are true to their word, and not what you pretend them to be. You measure them with your own rod; for neither contracts nor plighted troth avail with you, who are always saying nay and yea, according as you think it profitable. I must inform you, too, that the Pope promised me the sculptures, and so did Salviati; and they are men who will maintain me in my right to them. In what concerns you, I have done all I could to promote your interests and honour, not having earlier perceived that you never conferred a benefit on any one, and that, beginning with myself, to expect kindness from you, would be the same as wanting water not to wet. I have reason for what I say, since we have often met together in familiar converse, and may the day be cursed on which you ever said any good about anybody on earth." How Michelangelo answered this intemperate and unjust invective is not known to us. In some way or other the quarrel between the two sculptors must have been made up--probably through a frank apology on Sansovino's part. When Michelangelo, in 1524, supplied the Duke of Sessa with a sketch for the sepulchral monument to be erected for himself and his wife, he suggested that Sansovino should execute the work, proving thus by acts how undeserved the latter's hasty words had been.
