ndrea 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.

Now Tafi was a man of decent manners and pious. He was not like some painters who, on leaving the Churches where they have been depicting God creating the world and the infant Jesus in his holy mother's arms, go straight to houses of ill fame to play dice and drink, play the pipes and cuddle the girls. He had never wished for better than his good wife, albeit she was by no means made and moulded by the Creator to afford any great delight to men; for she was a very dry and a very chilling personage. Then, after God had removed her from this world to a better, in his loving mercy, Andrea took no other woman to his bosom either by marriage or otherwise. On the contrary he was strictly continent, as became his years, sparing himself both expense and vexation, and pleasing God to boot, who recompenses in the next world the privations men endure in this. Andrea Tafi was chaste, sober and well-advised.

He said his prayers with unfailing regularity, and being got to bed, he never fell asleep without first invoking the Blessed Virgin in these words:

"Holy Virgin, Mother of God, which for Thy merits wast exalted alive to Heaven, stretch forth Thy hand full of grace and mercy to me, to lift me up to that blessed Paradise where Thou sittest on a chair of gold."

And this petition old Tafi did not mumble between the two or three teeth he had left, but spoke it out in a loud, strong voice, persuaded it is the singing, as they say, makes the song, and that if you want to be heard, it is best to shout. Thus it came about that Master Tafi's supplication was overheard every night by Apollonius the Greek and the two young Florentines who lay in the next chamber. Now it so happened Apollonius was likewise of a merry humour, every whit as ready for a jest as Bruno or Buffalmacco. All three itched sore to play off some trick on the old painter, who was a just man and a god-fearing, but hard-fisted withal and a cruel taskmaster. Accordingly one night, after listening to the old fellow's customary address to the Virgin, the three comrades fell a-laughing under the bed-clothes and cutting a hundred jokes. Presently, when they heard him snoring, they began asking each other in whispers what jape they could play off on him. Well knowing the holy terror the old man had of the Devil, Apollonius proposed to go, dressed in red, with horns and a mask, to drag him out of bed by the feet. But the ingenious Buffalmacco had a better suggestion to offer:

"To-morrow we will provide ourselves with a good stout rope and a pulley, and I undertake to give you the same evening a highly diverting exhibition."

Apollonius and Bruno were curious to know what the pulley and rope were to be used for, but Buffalmacco refused to say. Nevertheless they promised faithfully to get him what he wanted; for they knew him to possess the merriest wit in the world and the most fertile in amusing contrivances, having earned his nickname of Buffalmacco for these very qualities. And truly he knew some excellent turns, that have since become legendary.

The three friends, having nothing now to keep them awake, fell asleep under the moon, which looking in at the garret window, pointed the tip of one of her horns, as if in mockery, at old Tafi. They slept sound till daybreak, when the master began hammering on the partition, and called out, coughing and spitting as usual.

"Get up, master Apollonius! Up with you, apprentices! Day's come; Phœbus has blown out the sky candles! Quick's the word! 'Life is short, and art long.'"
