When S. Francesco was at length finished Giotto returned to Florence, where he painted with extraordinary care, a picture of St Francis in the fearful desert of Vernia, to be sent to Pisa. Besides a landscape full of trees and rocks, a new thing in those days, the attitude of the saint, who is receiving the stigmata on his knees with great eagerness, exhibits an ardent desire to receive them and an infinite love towards Jesus Christ, who is in the air surrounded by seraphim granting them to him, the varied emotions being all represented in the most telling manner imaginable. The predella of the picture contains three finely executed subjects from the life of the same saint. The work may now be seen in S. Francesco at Pisa, on a pillar beside the high altar, where it is held in high veneration in memory of so great a man. It led the Pisans, on the completion of their Campo Santo from the plan of Giovanni di Niccola Pisano, as already related, to entrust to Giotto the painting of a part of the walls. For as the exterior of the walls was incrusted with marble and sculptures at a great cost, the roof being of lead, and the interior filled with antique sarcophagi and tombs of Pagan times, gathered together in that city from all parts of the world, the Pisans wished the walls to be decorated with a series of noble paintings. Accordingly Giotto went to Pisa, and beginning at the end of one of the walls of the Campo Santo he depicted the life of the patient Job in six frescoes. Now it occurred to him that the marbles of the part of the building in which he was at work were turned towards the sea, and being exposed to the south-east wind, they are always moist and throw out a certain saltness, as do nearly all the bricks of Pisa, and because the colours and paintings are eaten away by these causes, and as he wished to protect his work from destruction as far as possible, he prepared a coating for the whole of the surface on which he proposed to paint his frescoes, which consisted of a plaster or incrusture made up of lime, chalk and brick-dust. This device has proved so successful, that the paintings which he subsequently executed on this surface, have endured to this day, and they would have stood better had not the neglect of those who should have taken care of them, allowed them to be much damaged by the damp. The want of attention to this detail, which would have involved little trouble, has caused the pictures to suffer a great deal in some places where the damp has converted the crimsons into black and caused the plaster to fall off. Besides this it is the nature of chalk when mixed with lime to become corroded and to peel, whence it happens that the colours are destroyed, although they may originally appear to take well. These frescoes contain the portrait of M. Farinata degli Uberti, besides many fine figures, among which one may remark some countrymen, who in bringing the sad news to Job, exhibit
