But when he heard that Baccio had gone off to become a monk, Mariotto was almost overwhelmed and out of his mind; and so strange did the news seem to him, that he was in despair, and nothing could cheer him. If it had not been, indeed, that Mariotto could not then endure having anything to do with monks, against whom he was ever railing, and belonged to the party that was opposed to the faction of Fra Girolamo of Ferrara, his love for Baccio would have wrought upon him so strongly, that it would have forced him to don the cowl in the same convent as his companion. However, he was besought by Gerozzo Dini, who had given the commission for the Judgment that Baccio had left unfinished in the Ossa, that he, having a manner similar to Baccio's, should undertake to finish it; whereupon, being also moved by the circumstance that the cartoon completed by the hand of Baccio and other drawings were there, and by the entreaties of Fra Bartolommeo himself, who had received money on account of the painting, and was troubled in conscience at not having kept his promise, he finished the work, and executed all that was wanting with diligence and love, in such a way that many, not knowing this, think that it was painted by one single hand; and this brought him vast credit among craftsmen. In the Chapter-house of the Certosa of Florence he executed a Crucifixion, with Our Lady and the Magdalene at the foot of the Cross, and some angels in the sky, who are receiving the blood of Christ; a work wrought in fresco, with diligence and lovingness, and passing well painted. Now some of the young men who were learning art under him, thinking that the friars were not giving them proper food, had counterfeited, without the knowledge of Mariotto, the keys of those windows opening into the friar's rooms, through which their pittance is passed; and sometimes, in secret, they stole some of it, now from one and now from another. There was a great uproar about this among the friars, since in the matter of eating they are as sensitive as any other person; but the lads did it with great dexterity, and, since they were held to be honest fellows, the blame fell on some of the friars, who were said to be doing it from hatred of one another. However, one day the truth was revealed, and the friars, to the end that the work might be finished, gave a double allowance to Mariotto and his lads, who finished the work with great glee and laughter. For the Nuns of S. Giuliano in Florence he painted the panel of their high-altar, which he executed in a room that he had in the Gualfonda; together with another for the same church, with a Crucifix, some Angels, and God the Father, representing the Trinity, in oils and on a gold ground.
