"Hilloa! but you're a grand sleeper. I'll have you out of your slumbers, I will, though you should be dreaming this very moment that the eleven thousand virgins are slipping into your bed, begging you to teach 'em what's what." With these words on his lips, Andrea Tafi shoved the door of the room violently open. Then, catching sight of the points of fire running all over the floor, he stopped dead on the landing and fell a-trembling in every limb. "They're devils," he thought, "never a doubt of it,--devils and evil spirits. Why! they move with a sort of mathematical precision, which is their strong point, I've always been told. Naturally the Demons hate us painters, who depict them under hideous shapes, in contrast with the Angels we represent in glory, an aureole about their brows and waving wings of dazzling splendour. The unhappy boy is beset with devils; I can count at least a thousand around his pallet. No doubt he has angered Lucifer himself, by drawing some horrible picture of him. 'Tis only too likely these ten thousand imps here will leap upon him and carry him off alive to Hell. His doom is fixed. And alack! I have myself figured, in mosaic and other ways, very odious caricatures of Devils, and they have good reason to bear me a grudge too." The thought redoubled his fears, and hauling up his hose, he took to his heels, too much terrified to think of facing the hundred thousand hobgoblins he had seen wheeling round and round with bodies of fire, and dashed down the stairs as fast as ever his old legs would carry him. Buffalmacco had a fine laugh under the sheets, and for once in a way slept on till broad daylight. Nor did his master ever again dare to go and wake him. II THE ASCENDING UP OF ANDREA TAFI Andrea Tafi, of Florence, being chosen to decorate the cupola of San Giovanni with mosaics, carried out the said work in the most perfect fashion. Every figure was treated in the Greek manner, which Tafi had learned during his sojourn at Venice, where he had seen workmen busy adorning the walls of San Marco. He had even brought back with him from that city a Greek by name Apollonius, who knew excellent secrets for designing in mosaic. This Apollonius was a skilful workman and a very clever man. He knew the proportions to be given to the different parts of the human body and the material for mixing the best cement. Fearing the Greek might carry his knowledge and address to some other painter of the city, Andrea Tafi never left his side day or night Every morning he took him with him to San Giovanni, and brought him home every evening to his own house, facing San Michele, and made him sleep there with his two apprentices, Bruno and Buffalmacco, in a room separated merely by a partition from his own bed-chamber. And as this partition left half a foot between the top and the beams of the ceiling, whatever was said in one room could easily be overheard in the other.
