It is dated Rome, July 8, 1506, and contains this passage: "Michelangelo the sculptor, who left us without reason, and in mere caprice, is afraid, as we are informed, of returning, though we for our part are not angry with him, knowing the humours of such men of genius.

In order, then, that he may lay aside all anxiety, we rely on your loyalty to convince him in our name, that if he returns to us, he shall be uninjured and unhurt, retaining our apostolic favour in the same measure as he formerly enjoyed it." The date, July 8, is important in this episode of Michelangelo's life.

Soderini sent back an answer to the Pope's brief within a few days, affirming that "Michelangelo the sculptor is so terrified that, notwithstanding the promise of his Holiness, it will be necessary for the Cardinal of Pavia to write a letter signed by his own hand to us, guaranteeing his safety and immunity.

We have done, and are doing, all we can to make him go back; assuring your Lordship that, unless he is gently handled, he will quit Florence, as he has already twice wanted to do." This letter is followed by another addressed to the Cardinal of Volterra under date July 28.

Soderini repeats that Michelangelo will not budge, because he has as yet received no definite safe-conduct.
