The first pictures of Paolo were in fresco, in an oblong niche painted in perspective, at the Hospital of Lelmo—namely, a figure of S. Anthony the Abbot, with S. Cosimo on one side and S. Damiano on the other. In the Annalena, a convent of nuns, he made two figures; and within the Church of S. Trinita, over the left-hand door, he painted stories of S. Francis in fresco—namely, the receiving of the Stigmata; the supporting of the Church, which he is upholding with his shoulders; and his conference with S. Dominic. In S. Maria Maggiore, also, in a chapel near the side-door which leads to S. Giovanni, where there are the panel and predella of Masaccio, he wrought an Annunciation in fresco, wherein he made a building worthy of consideration, which was something new and difficult in those times, seeing that it was the first possessing any beauty of manner which was seen by craftsmen, showing them with grace and proportion how to manage the receding of lines, and how to give so great an extent to a level space which is small and confined, that it appears far distant and large; and when to this, with judgment and grace, men can add shadows and lights by means of colours in their proper places, there is no doubt that they cause an illusion to the eye, so that it appears that the painting is real and in relief. And not being satisfied with this, he wished to demonstrate even greater difficulties in some columns, which, foreshortened in perspective, curve round and break the salient angle of the vaulting wherein are the four Evangelists; which was held something beautiful and difficult, and, in truth, in that branch of his profession Paolo was ingenious and able.
In a cloister of S. Miniato without Florence, also, he wrought the lives of the Holy Fathers, chiefly in terra-verde, and partly in colour; wherein he paid little regard to effecting harmony by painting with one colour, as should be done in painting stories, for he made the fields blue, the cities red, and the buildings varied according to his pleasure; and in this he was at fault, for something which is meant to represent stone cannot and should not be tinted with another colour. It is said that while Paolo was labouring at this work, the Abbot who was then head of that place gave him scarcely anything to eat but cheese. Wherefore Paolo, having grown weary of this, determined, like the shy fellow that he was, to go no more to work there; whereupon the Abbot sent to look for him, and Paolo, when he heard friars asking for him, would never be at home, and if peradventure he met any couples of that Order in the streets of Florence, he would start running and flying from them with all his might. Now two of them, more curious than the rest and younger than Paolo, caught him up one day and asked him for what reason he did not return to finish the work that he had begun, and why he fled at the sight of a friar; and Paolo answered: "You have murdered me in a manner that I not only fly from you, but cannot show myself near any carpenter's shop or pass by one, and all because of the thoughtlessness of your Abbot, who, what with pies and with soups always made of cheese, has crammed so much cheese into me that I am in terror lest, being nothing but cheese, they may use me for making glue. And if it were to go on any longer, I would probably be no more Paolo, but cheese." The friars, leaving him with peals of laughter, told everything to the Abbot, who made him return to his work, and ordered him some other fare than cheese.
After this, he painted the dossal of S. Cosimo and S. Damiano in the Carmine, in the Chapel of S. Girolamo (of the Pugliesi). In the house of the Medici he painted some scenes on canvas and in distemper, representing animals; in these he ever took delight, and in order to paint them well he gave them very great attention, and, what is more, he kept ever in his house pictures of birds, cats, dogs, and every sort of strange animal whereof he could get the likeness, being unable to have them alive by reason of his poverty; and because he delighted in birds more than in any other kind, he was given the name of "Paolo of the Birds" (Paolo Uccelli). In the said house, among other pictures of animals, he made some lions, which were fighting together with movements and a ferocity so terrible that they appeared alive. But the rarest scene among them all was one wherein a serpent, combating with a lion, was showing its ferocity with violent movements, with the venom spurting from its mouth and eyes, while a country girl who is present is looking after an ox made with most beautiful foreshortening. The actual drawing for this ox, by the hand of Paolo, is in my book of drawings, and likewise that of the peasant girl, all full of fear, and in the act of running away from those animals. There are likewise certain very lifelike shepherds, and a landscape which was held something very beautiful in his time. In the other canvases he made some studies of men-at-arms of those times, on horseback, with not a few portraits from the life.
Afterwards he was commissioned to paint some scenes in the cloister of S. Maria Novella; and the first, which are at the entrance from the church into the cloister, represent the Creation of the animals, with an infinite number and variety of kinds belonging to water, earth, and air. And since he was very fanciful and took great delight, as it has been said, in painting animals to perfection, he showed in certain lions, who are seeking to bite each other, the great ferocity that is in them, and swiftness and fear in some stags and fallow-deer; not to mention that the birds and fishes, with their feathers and scales, are most lifelike. He made there the Creation of man and of woman, and their Fall, with a beautiful manner and with good and careful execution. And in this work he took delight in making the trees with colours, which the painters of those times were not wont to do very well; and in the landscapes, likewise, he was the first among the old painters to make a name for himself by his work, executing them well and with greater perfection than the painters before him had done; although afterwards there came men who made them more perfect, for with all his labour he was never able to give them that softness and harmony which have been given to them in our own day by painting them in oil-colours. It was enough for Paolo to go on, according to the rules of perspective, drawing and foreshortening them exactly as they are, making in them all that he saw—namely, ploughed fields, ditches, and other minutenesses of nature—with that dry and hard manner of his; whereas, if he had picked out the best from everything and had made use of those parts only that come out well in painting, they would have been absolutely perfect. This labour finished, he worked in the same cloister below two stories by the hand of others; and lower down he painted the Flood, with Noah's Ark, wherein he put so great pains and so great art and diligence into the painting of the dead bodies, the tempest, the fury of the winds, the flashes of the lightning, the shattering of trees, and the terror of men, that it is beyond all description. And he made, foreshortened in perspective, a corpse from which a raven is picking out the eyes, and a drowned boy, whose body, being full of water, is swollen out into the shape of a very great arch. He also represented various human emotions, such as the little fear of the water shown by two men who are fighting on horseback, and the extreme terror of death seen in a woman and a man who are mounted on a buffalo, which is filling with water from behind, so that they are losing all hope of being able to save themselves; and the whole work is so good and so excellent, that it brought him very great fame. He diminished the figures, moreover, by means of lines in perspective, and made mazzocchi and other things, truly very beautiful in such a work. Below this story, likewise, he painted the drunkenness of Noah, with the contemptuous action of his son Ham—in whom he portrayed Dello, the Florentine painter and sculptor, his friend—with Shem and Japhet, his other sons, who are covering him up as he lies showing his nakedness. Here, likewise, he made in perspective a cask that curves on every side, which was held something very beautiful, and also a pergola covered with grapes, the wood-work of which, composed of squared planks, goes
