However, he had not visited the cellar to ponder on symbols and emblems, and he was not long in carrying out his plan. He caught two dozen of the cockroaches, without regard to sex or age, and popped them in a bag he had brought with him for the purpose. This done, he proceeded to hide the bag under his bed, and returned to the workroom, where his comrades Bruno and Calendrino were painting, from the master's sketches, the good St. Francis receiving the stigmata, and meantime devising some way of hoodwinking Memmi the cobbler, whose wife was comely and obliging. Buffalmacco, who was not less expert, far from it, than his two comrades, mounted the ladder and started painting the wings of the seraphic crucifix that came down from heaven to mark the Blessed Saint with the five wounds of love, taking the utmost pains to blend in the celestial pinions all the tenderest hues of the rainbow. The task occupied him all day, and when old Tafi came back from San Giovanni, he could not refrain from bestowing a few words of commendation on his pupil. This cost him no small effort, for age and riches had made him both cross and critical. "My lads," he said, addressing the apprentices, "those wings are painted with a good deal of spirit. Buffalmacco might go far in the art of painting, if he would only apply himself more vigorously. But there, his mind is far too much set on self-indulgence; and great achievements can only be accomplished by steady labour. Now Calendrino here would beat you all, with his industry--if he were not a born fool."
