"Among the Three Hundred Stories of Franco Saccheti," says Vasari, "we find it related to begin with, what our artist did in his youth--that when Buffalmacco was studying with Andrea Tafi, his master had the habit of rising before daylight when the nights were long, compelling his scholars also to awake and proceed to their work. This provoked Buonamico, who did not approve of being aroused from his sweetest sleep. He accordingly bethought himself of finding some means by which Andrea might be prevented from rising so early, and soon found what he sought." Now it happened that Tafi was a very superstitious man, believing that demons and hobgoblins walked the earth at their pleasure. Buffalmacco, having caught about thirty large beetles, he fastened to the back of each, by means of small needles, a minute taper, which he lighted, and sent them one by one into his master's room, through a crack in the door, about the time he was accustomed to rise and summon him to his labors. Tafi seeing these strange lights wandering about his room, began to tremble with fright, and repeated his prayers and exorcisms, but finding they produced no effect on the apparitions, he covered his head with the bed clothes, and lay almost petrified with terror till daylight. When he rose he enquired of Buonamico, if "he had seen more than a thousand demons wandering about his room, as he had himself in the night?" Buonamico replied that he had seen nothing, and wondered he had not been called to work. "Call thee to work!" exclaimed the master, "I had other things to think of besides painting, and am resolved to stay in this house no longer;" and away he ran to consult the parish priest, who seems to have been as superstitious as the poor painter himself. When Tafi discoursed of this strange affair with Buonamico, the latter told him that he had been taught to believe that the demons were the greatest enemies of God, consequently they must be the most deadly adversaries of painters. "For," said he, "besides that we always make them most hideous, we think of nothing but painting saints, both men and women, on walls and pictures, which is much worse, since we thereby render men better and more devout to the great despite of the demons; and for all this, the devils being angry with us, and having more power by night than by day, they play these tricks upon us. I verily believe too, that they will get worse and worse, if this practice of rising to work in the night be not discontinued altogether." Buffalmacco then advised his master to make the experiment, and see whether the devils would disturb him if he did not work at night. Tafi followed this advice for a short time, and the demons ceased to disturb him; but forgetting his fright, he began to rise betimes, as before, and to call Buffalmacco to his work. The beetles then recommenced their wanderings, till Tafi was compelled by his fears and the earnest advice of the priest to desist altogether from that practice.
