that the Abbess had some Vernaccia, the best in Florence, which was used for the holy office of the Mass, said to them that in order to remedy this defect nothing else could be done but to temper the colours with some good Vernaccia; because, touching the cheeks and the rest of the flesh on the figures with colours thus tempered, they would become rosy and coloured in most lifelike fashion. Hearing this, the good sisters, who believed it all, kept him ever afterwards furnished with the best Vernaccia, as long as the work lasted; and he, rejoicing in it, from that time onwards made the figures fresher and more highly coloured with his ordinary colours. This work finished, he painted some stories of S. James in the Abbey of Settimo, in the chapel that is in the cloister, and dedicated to that Saint, on the vaulting of which he made the four Patriarchs and the four Evangelists, among whom S. Luke is doing a striking action in blowing very naturally on his pen, in order that it may yield its ink. Next, in the scenes on the walls, which are five, there are seen beautiful attitudes in the figures, and the whole work is executed with invention and judgment. And because Buonamico was wont, in order to make his flesh-colour better, as is seen in this work, to make a ground of purple, which in time produces a salt that becomes corroded and eats away the white and other colours, it is no marvel if this work is spoilt and eaten away, whereas many others that were made long before have been very well preserved. And I, who thought formerly that these pictures had received injury from the damp, have since proved by experience, studying other works of the same man, that it is not from the damp but from this particular use of Buffalmacco's that they have become spoilt so completely that there is not seen in them either design or anything else, and that where the flesh-colours were there has remained nothing else but the purple. This method of working should be used by no one who is anxious that his pictures should have long life.
