n this work are innumerable colours, flashed one over the
other in the glass, and every least thing truly appears most natural
in its own kind.

And whoever wishes to learn how much the hand of the Prior was able
to effect in this art, should study the window of S. Matthew over
the Chapel of that Apostle, and observe the marvellous invention of
that scene, wherein he can see a living figure of Christ calling
Matthew from his tables, while Matthew, following Him and stretching
out his arms to receive Him, abandons the riches and treasures that
he has acquired. And at the same time an Apostle may be seen in a
very spirited attitude, awaking another who has fallen asleep on
some steps; and in like manner there may also be perceived a S.
Peter speaking with S. John, both being so beautiful that they seem
truly divine. In this same window are temples in perspective,
staircases, and figures so well grouped, and landscapes so natural,
that one would never think it was glass, but rather a thing rained

he made the window of S. Anthony and that of S. Nicholas, both most
beautiful, with two others, one containing the scene of Christ
driving the traders from the Temple, and the other that of the woman

So fully were the labours and abilities of the Prior recognized by
the Aretines, what with praises, favours, and rewards, and so

adopt that city as his home, and to change himself from a Frenchman
into an Aretine. Afterwards, reflecting in his own mind that the art
of glass-painting, on account of the destruction that takes place
every moment in such works, was no lasting one, there came to him a
desire to devote himself to painting, and he therefore undertook to
execute for the Wardens of Works of the Vescovado in that city three
very large vaults in fresco, thinking thus to leave a memorial of
himself behind him. The Aretines, in return for this, presented to
him a farm that belonged to the Confraternity of S. Maria della
Misericordia, near their city, with some excellent houses, for his
enjoyment during his lifetime. And they ordained that when the work
was finished, its value should be estimated by some distinguished
craftsman, and that the Wardens should make this good to him in
full. Whereupon he made up his mi
