Giotto, about to paint a picture of the Crucifixion, induced a poor man to suffer himself to be bound to a cross, under the promise of being set at liberty in an hour, and handsomely rewarded for his pains. Instead of this, as soon as Giotto had made his victim secure, he seized a dagger, and, shocking to tell, stabbed him to the heart! He then set about painting the dying agonies of the victim to his foul treachery. When he had finished his picture, he carried it to the Pope; who was so well pleased with it, that he resolved to place it above the altar of his own chapel. Giotto observed, that, as his holiness liked the copy so well, he might perhaps like to see the original. The Pope, shocked at the impiety of the idea, uttered an exclamation of surprise. "I mean," added Giotto, "I will show you the person whom I employed as my model in this picture, but it must be on condition that your holiness will absolve me from all punishment for the use which I have made of him." The Pope promised Giotto the absolution for which he stipulated, and accompanied the artist to his workshop. On entering, Giotto drew aside a curtain which hung before the dead man, still stretched on the cross, and covered with blood. The barbarous exhibition struck the pontiff with horror; he told Giotto he could never give him absolution for so cruel a deed, and that he must expect to suffer the most exemplary punishment. Giotto, with seeming resignation, said that he had only one favor to ask, that his holiness would give him leave to finish the piece before he died. The request had too important an object to be denied; the Pope readily granted it; and, in the meantime, a guard was set over Giotto to prevent his escape.
