_E si compiacque tanto Spinello di farlo orribile e contrafatto, che si dice (tanto può alcuna fiata l'immaginazione) che la detta figura da lui dipinta gli apparve in sogno, domandandolo dove egli l' avesse veduta si brutta._[1] (_Vite de' piu eccellenti pittori_, da Messer Giorgio Vasari.--"Vita di Spinello.") [Footnote 1: "And so successful was Spinello with his horrible and portentous Production that it was commonly reported--so great is alway the force of fancy--that the said figure (of Lucifer trodden underfoot by St. Michael in the Altar-piece of the Church of St. Agnolo at Arezzo) painted by him had appeared to the artist in a dream, and asked him in what place he had beheld him under so brutish a form." _Lives of the most Excellent Painters_, by Giorgio Vasari.--"Life of Spinello."] Andrea Tafi, painter and worker-in-mosaic of Florence, had a wholesome terror of the Devils of Hell, particularly in the watches of the night, when it is given to the powers of Darkness to prevail. And the worthy man's fears were not unreasonable, for in those days the Demons had good cause to hate the Painters, who robbed them of more souls with a single picture than a good little Preaching Friar could do in thirty sermons. No doubt the Monk, to instil a soul-saving horror in the hearts of the faithful, would describe to the utmost of his powers "that day of wrath, that day of mourning," which is to reduce the universe to ashes, _teste David et Sibylla_, borrowing his deepest voice and bellowing through his hands to imitate the Archangel's last trump. But there! it was "all sound and fury, signifying nothing," whereas a painting displayed on a Chapel wall or in the Cloister, showing Jesus Christ sitting on the Great White Throne to judge the living and the dead, spoke unceasingly to the eyes of sinners, and through the eyes chastened such as had sinned by the eyes or otherwise.
