Parri, then, having been absent many years from his country, was recalled by his relatives, after the death of his father, to Arezzo, where, besides many works which it would take too long to recount, he made some which do not in any way deserve to be passed over in silence. In the Duomo Vecchio he made in fresco three different figures of Our Lady; and within the principal door of that church, on the left hand as one enters, he painted in fresco a story of the Blessed Tommasuolo, a sack-cloth hermit and a holy man of that time. And since this man was wont to carry in his hand a mirror wherein he saw, so he declared, the Passion of Christ, Parri portrayed him in that story kneeling, with that mirror in his right hand, which he was holding uplifted towards Heaven. And painting Jesus Christ above on a throne of clouds, and round him all the Mysteries of the Passion, with most beautiful art he made them all reflected in that mirror, in such wise that not only the Blessed Tommasuolo but all who beheld that picture could see them, which invention was truly fanciful and difficult, and so beautiful that it taught those who came after him to counterfeit many things by means of mirrors. Nor will I forbear to tell, now that I am dealing with this subject, what this holy man did once in Arezzo; and it is this. Labouring continually, without ever ceasing, to induce the Aretines to live at peace with one another, now preaching, and now foretelling many misadventures, he recognized finally that he was wasting his time. Whereupon, entering one day into the Palace where the Sixty were wont to assemble, the said Blessed Tommasuolo--who saw them every day deliberating, and never coming to any resolution save such as injured the city--when he saw that the Hall was full, placed a quantity of burning coals into a great fold in his robe, and, advancing with these towards the Sixty and all the other magistrates of the city, he threw them boldly at their feet, saying: "My lords, the fire is among you; take heed lest ruin come upon you;" and this said, he went his way. Such was the effect of the simplicity, and, as it pleased God, of the good counsel of that holy man, that the said action completely accomplished what his preachings and threatenings had never been able to do, insomuch that, becoming united among themselves no long time after, they governed that city for many years afterwards with much peace and quiet for all.
