After this he put a brush in the spout from which the water flows, and there left it. When the nuns returned to see the work through an opening where he had torn the canvas, they saw the supposed master in his attire. They believed that he was working there to the utmost of his power, and would do much better than the mere boy had done, so they were several days thinking of nothing else. At last they were anxious to see what beautiful things the master had made. Fifteen days had passed since Buonamico had set foot in the place, and one night they went to see the paintings, thinking that the master could no longer be there. They were covered with confusion and blushes when one bolder than the rest discovered the nature of the solemn master, who had not done a stroke in the fortnight. When they learned that Buonamico had treated them according to their deserts, and that the works which he had made were excellent, they recalled him and he returned with much laughter and joking to take up the work, making them see that there is a difference between men and dummies, and that works must not always be judged by the clothes of those who produce them. After a few days he finished one subject there, with which they were very delighted since it appeared to them to be satisfactory in all its parts, except that the figures in the flesh colouring seemed to them to be rather too pale. When Buonamico heard this and learning that the abbess had the best vernaccia in Florence, which served for the sacrifice of the mass, he told them that in order to remedy such a defect, nothing would be serviceable except to temper the colours with a good vernaccia, for if the cheeks and other flesh parts of the figures were touched with this, they would become red and very freshly coloured. When the good sisters heard this they believed it completely and afterwards kept him supplied with the best vernaccia so long as the work lasted, while he on his part made merry and thenceforward with his ordinary colours rendered his figures more fresh and brilliant.
