Work being then begun on the broad festoons that were to run in clusters round the windows, Vasari made one with his own hand, keeping real fruits in front of him, that he might copy them from nature. This done, he ordained that Cristofano and Stefano should go on with the rest, holding to the same design, one on one side of the window, and the other on the other side, and should thus, one by one, proceed to finish them all; promising to him who might prove at the end of the work to have acquitted himself best a pair of scarlet hose. And so, competing lovingly for both honour and profit, they set themselves to copy everything, from the large things down to the most minute, such as millet-seed, hemp-seed, bunches of fennel, and the like, in such a manner that those festoons proved to be very beautiful; and both of them received from Vasari the prize of the scarlet hose.
Giorgio took great pains to persuade Cristofano to execute by himself part of the designs for the scenes that were to go into the frieze, but he would never do it. Wherefore, the while that Giorgio was drawing them himself, Gherardi executed the buildings in two of the panel-pictures, with much grace and beauty of manner, and such perfection, that a master of great judgment, even if he had had the cartoons before him, could not have done what Cristofano did. And, in truth, there never was a painter who could do by himself, and without study, the things that he contrived to do. After having finished the execution of the buildings in the two panel-pictures, the while that Vasari was carrying to completion the twenty stories from the Apocalypse for the above-mentioned frieze, Cristofano, taking in hand the panel-picture in which S. Gregory (whose head is a portrait of Pope Clement VII) is eating with his twelve poor men, executed the whole service of the table, all very lifelike and most natural. Then, a beginning having been made with the third panel-picture, while Stefano was occupied with the gilding of the ornamental frames of the other two, a staging was erected upon two trestles of wood, from which, while Vasari was painting on one side, in a glory of sunlight, the three Angels that appeared to Abraham in the Valley of Mamre, Cristofano painted some buildings on the other side. But he was always making some contraption with stools and tables, and at times with basins and pans upside down, on which he would climb, like the casual creature that he was; and once it happened that, seeking to draw back in order to look at what he had done, one of his feet gave way under him, the whole contraption turned topsy-turvy, and he fell from a height of five braccia, bruising himself so grievously that he had to be bled and properly nursed, or he would have died. And, what was worse, being the sort of careless fellow that he was, one night there slipped off the bandages that were on the arm from which the blood had been drawn, to the great danger of his life, so that, if Stefano, who was sleeping with him, had not noticed this, it would have been all up with him; and even so Stefano had something to do to revive him, for the bed was a lake of blood, and he himself was reduced almost to his last gasp. Vasari, therefore, taking him under his own particular charge, as if he had been his brother, had him tended with the greatest possible care, than which, indeed, nothing less would have sufficed; and with all this he was not restored until that work was completely finished. After that, returning to S. Giustino, Cristofano completed some of the apartments of the Abbot there, which had been left unfinished, and then executed at Città di Castello, all with his own hand, an altar-piece that had been allotted to Battista, his dearest friend, and a lunette that is over the side-door of S. Fiorido, containing three figures in fresco.
