That Stefano did not always behave himself according to his master's wishes appears from the following characteristic letter addressed by Michelangelo to his friend Pietro Gondi: "The poor man, who is ungrateful, has a nature of this sort, that if you help him in his needs, he says that what you gave him came out of superfluities; if you put him in the way of doing work for his own good, he says you were obliged, and set him to do it because you were incapable; and all the benefits which he received he ascribes to the necessities of the benefactor. But when everybody can see that you acted out of pure benevolence, the ingrate waits until you make some public mistake, which gives him the opportunity of maligning his benefactor and winning credence, in order to free himself from the obligation under which he lies. This has invariably happened in my case. No one ever entered into relations with me--I speak of workmen--to whom I did not do good with all my heart. Afterwards, some trick of temper, or some madness, which they say is in my nature, which hurts nobody except myself, gives them an excuse for speaking evil of me and calumniating my character. Such is the reward of all honest men." These general remarks, he adds, apply to Stefano, whom he placed in a position of trust and responsibility, in order to assist him. "What I do is done for his good, because I have undertaken to benefit the man, and cannot abandon him; but let him not imagine or say that I am doing it because of my necessities, for, God be praised, I do not stand in need of men." He then begs Gondi to discover what Stefano's real mind is. This is a matter of great importance to him for several reasons, and especially for this: "If I omitted to justify myself, and were to put another in his place, I should be published among the Piagnoni for the biggest traitor who ever lived, even though I were in the right." We conclude, then, that Michelangelo thought of dismissing Stefano, but feared lest he should get into trouble with the powerful political party, followers of Savonarola, who bore the name of Piagnoni at Florence. Gondi must have patched the quarrel up, for we still find Stefano's name in the _Ricordi_ down to April 4, 1524. Shortly after that date, Antonio Mini seems to have taken his place as Michelangelo's right-hand man of business. These details are not so insignificant as they appear. They enable us to infer that the Sacristy of S. Lorenzo may have been walled and roofed in before the end of April 1524; for, in an undated letter to Pope Clement, Michelangelo says that Stefano has finished the lantern, and that it is universally admired. With regard to this lantern, folk told him that he would make it better than Brunelleschi's. "Different perhaps, but better, no!" he answered. The letter to Clement just quoted is interesting in several respects. The boldness of the beginning makes one comprehend how Michelangelo was terrible even to Popes:--
