Going from Loreto to Arezzo, Piero painted for Luigi Bacci, a citizen of Arezzo, the Chapel of the High-altar of S. Francesco, belonging to that family, the vaulting of which had been already begun by Lorenzo di Bicci. In this work there are Stories of the Cross, from that wherein the sons of Adam are burying him and placing under his tongue the seed of the tree from which there came the wood for the said Cross, down to the Exaltation of the Cross itself performed by the Emperor Heraclius, who, walking barefoot and carrying it on his shoulder, is entering with it into Jerusalem. Here there are many beautiful conceptions and attitudes worthy to be extolled; such as, for example, the garments of the women of the Queen of Sheba, executed in a sweet and novel manner; many most lifelike portraits from nature of ancient persons; a row of Corinthian columns, divinely well proportioned; and a peasant who, leaning with his hands on his spade, stands listening to the words of S. Helena—while the three Crosses are being disinterred—with so great attention, that it would not be possible to improve it. Very well wrought, also, is the dead body that is restored to life at the touch of the Cross, together with the joy of S. Helena and the marvelling of the bystanders, who are kneeling in adoration. But above every other consideration, whether of imagination or of art, is his painting of Night, with an angel in foreshortening who is flying with his head downwards, bringing the sign of victory to Constantine, who is sleeping in a pavilion, guarded by a chamberlain and some men-at-arms who are seen dimly through the darkness of the night; and with his own light the angel illuminates the pavilion, the men-at-arms, and all the surroundings. This is done with very great thought, for Piero gives us to know in this darkness how important it is to copy things as they are and to ever take them from the true model; which he did so well that he enabled the moderns to attain, by following him, to that supreme perfection wherein art is seen in our own time. In this same story he represented most successfully in a battle fear, animosity, dexterity, vehemence, and all the other emotions that can be imagined in men who are fighting, and likewise all the incidents of battle, together with an almost incredible carnage, what with the wounded, the fallen, and the dead. In these Piero counterfeited in fresco the glittering of their arms, for which he deserves no less praise than he does for the flight and submersion of Maxentius painted on the other wall, wherein he made a group of horses in foreshortening, so marvellously executed that they can be truly called too beautiful and too excellent for those times. In the same story he made a man, half nude and half clothed in the dress of a Saracen, riding a lean horse, which reveals a very great mastery of anatomy, a science little known in his age. For this work, therefore, he well deserved to be richly rewarded by Luigi Bacci, whom he portrayed there in the scene of the beheading of a King, together with Carlo and others of his brothers and many Aretines who were then distinguished in letters; and to be loved and revered ever afterwards, as he was, in that city, which he had made so illustrious with his works.
In the Vescovado of the same city, also, he made a S. Mary Magdalene in fresco beside the door of the sacristy; and for the Company of the Nunziata he painted the banner that is carried in processions. At the head of a cloister at S. Maria delle Grazie, without that district, he painted S. Donatus in his robes, seated in a chair drawn in perspective, together with certain boys; and in a niche high up on a wall of S. Bernardo, for the Monks of Monte Oliveto, he made a S. Vincent, which is much esteemed by craftsmen. In a chapel at Sargiano, a seat of the Frati Zoccolanti di S. Francesco, without Arezzo, he painted a very beautiful Christ praying by night in the Garden.
In Perugia, also, he wrought many works that are still to be seen in that city; as, for example, a panel in distemper in the Church of the Nuns of S. Anthony of Padua, containing a Madonna with the Child in her lap, S. Francis, S. Elizabeth, S. John the Baptist, and S. Anthony of Padua. Above these is a most beautiful Annunciation, with an Angel that seems truly to have come out of Heaven; and, what is more, a row of columns diminishing in perspective, which is indeed beautiful. In the predella there are scenes with little figures, representing S. Anthony restoring a boy to life; S. Elizabeth saving a child that has fallen into a well; and S. Francis receiving the Stigmata. In S. Ciriaco at Ancona, on the altar of S. Giuseppe, he painted a most beautiful scene of the Marriage of Our Lady.
Piero, as it has been said, was a very zealous student of art, and gave no little attention to perspective; and he had a very good knowledge of Euclid, insomuch that he understood all the best curves drawn in regular bodies better than any other geometrician, and the clearest elucidations of these matters that we have are from his hand. Now Maestro Luca dal Borgo, a friar of S. Francis, who wrote about the regular geometrical bodies, was his pupil; and when Piero, after having written many books, grew old and finally died, the said Maestro Luca, claiming the authorship of these books, had them printed as his own, for they had fallen into his hands after the death of Piero.
Piero was much given to making models in clay, on which he spread wet draperies with an infinity of folds, in order to make use of them for drawing.
A disciple of Piero was Lorentino d'Angelo of Arezzo, who made many pictures in Arezzo, imitating his manner, and completed those that Piero, overtaken by death, left unfinished. Near the S. Donatus that Piero wrought in the Madonna delle Grazie, Lorentino painted in fresco some stories of S. Donatus, with very many works in many other places both in that city and in the district, partly because he would never stay idle, and partly to assist his family, which was then very poor. In the said Church of the Grazie the same man painted a scene wherein Pope Sixtus IV, between the Cardinal of Mantua and Cardinal Piccolomini (who was afterwards Pope Pius III), is granting an indulgence to that place; in which scene Lorentino portrayed from the life, on their knees, Tommaso Marzi, Piero Traditi, Donato Rosselli, and Giuliano Nardi, all citizens of Arezzo and Wardens of Works for that building. In the hall of the Palazzo de' Priori, moreover, he portrayed from the life Cardinal Galeotto da Pietramala, Bishop Guglielmino degli Ubertini, and Messer Angelo Albergotti, Doctor of Laws; and he made many other works, which are scattered throughout that city.
It is said that once, when the Carnival was close at hand, the children of Lorentino kept beseeching him to kill a pig, as it is the custom to do in that district; and that, since he had not the means to buy one, they would say, "What will you do about buying a pig, father, if you have no money?" To which Lorentino would answer, "Some Saint will help us." But when he had said this many times and the season was passing by without any pig appearing, they had lost hope, when at length there arrived a peasant from the Pieve a Quarto, who wished to have a S. Martin painted in fulfilment of a vow, but had no means of paying for the picture save a pig, which was worth five lire. This man, coming to Lorentino, told him that he wished to have the S. Martin painted, but that he had no means of payment save the pig. Whereupon they came to an agreement, and Lorentino painted him the Saint, while the peasant brought him the pig; and so the Saint provided the pig for the poor children of this painter.
Another disciple of Piero was Pietro da Castel della Pieve,[4] who painted an arch above S. Agostino, and a S. Urban for the Nuns of S. Caterina in Arezzo, which has been thrown to the ground in rebuilding the church. His pupil, likewise, was Luca Signorelli of Cortona, who did him more honour than all the others.
Piero Borghese, whose pictures date about the year 1458, became blind through an attack of catarrh at the age of sixty, and lived thus up to the eighty-sixth year of his life. He left very great possessions in the Borgo, with some houses that he had built himself, which were burnt and destroyed in the strife of factions in the year 1536. He was honourably buried by his fellow-citizens in the principal church, which formerly belonged to the Order of Camaldoli, and is now the Vescovado. Piero's books are for the most part in the library of Frederick II, Duke of Urbino, and they are such that they have deservedly acquired for him the name of the best geometrician of his time.
