It is said that having been commissioned to paint, over the door of S. Tommaso in the Mercato Vecchio, that Saint feeling for the wound in the side of Christ, Paolo put into that work all the effort that he could, saying that he wished to show therein the full extent of his worth and knowledge; and so he caused a screen of planks to be made, to the end that no one might be able to see his work until it was finished. Wherefore Donato, meeting him one day all alone, said to him: "And what sort of work may this be of thine, that thou keepest it screened so closely?" And Paolo said in answer: "Thou shalt see it. Let that suffice thee." Donato would not constrain him to say more, thinking to see some miracle, as usual, when the time came. Afterwards, chancing one morning to be in the Mercato Vecchio buying fruit, Donato saw Paolo uncovering his work, whereupon he saluted him courteously, and was asked by Paolo himself, who was curious and anxious to hear his judgment on it, what he thought of that picture. Donato, having studied the work long and well, exclaimed: "Ah, Paolo, thou oughtest to be covering it up, and here thou art uncovering it!" Whereupon Paolo was much aggrieved, feeling that he was receiving much more by way of blame than he expected to receive by way of praise for this last labour of his; and not having courage, lowered as he was, to go out any more, he shut himself up in his house, devoting himself to perspective, which kept him ever poor and depressed up to his death. And so, growing very old, and having but little contentment in his old age, he died in the eighty-third year of his life, in 1432, and was buried in S. Maria Novella. He left a daughter, who had knowledge of drawing, and a wife, who was wont to say that Paolo would stay in his study all night, seeking to solve the problems of perspective, and that when she called him to come to bed, he would say: "Oh, what a sweet thing is this perspective!" And in truth, if it was sweet to him, it was not otherwise than dear and useful, thanks to him, to those who exercised themselves therein after his time.
