ze the above-mentioned statues of which
they had made the moulds; which things, both the one and the other, he
did with much diligence and judgment. After two years had passed, he
returned to Bologna, according to the promise made by him to Count
Filippo Pepoli, in order to attend to the building of S. Petronio. In
that place he consumed several years in discussions and disputes with
certain others who were his competitors in the affairs there, without
doing anything but design and cause to be constructed after his plans
the canal that brings vessels into Bologna, whereas before that they
could not come within three miles; than which work none better or more
useful was ever executed, although Vignuola, the originator of an
enterprise so useful and so praiseworthy, was poorly rewarded for it.

Pope Julius III having been elected in the year 1550, by means of Vasari
Vignuola was appointed architect to his Holiness, and there was given to
him the particular charge of conducting the Acqua Vergine and of
superintending the works at the Vigna of Pope Julius, who took Vignuola
into his service most willingly, because he had come to know him when he
was Legate in Bologna. In that building, and in other works that he
executed for that Pontiff, he endured much labour, but was badly
rewarded for it. Finally Cardinal Alessandro Farnese, having recognized
the genius of Vignuola, to whom he always showed much favour, desired,
in carrying out the building of his Palace at Caprarola, that the whole
work should spring from the fanciful design and invention of Vignuola.
And, in truth, the judgment of that lord in making choice of so
excellent an architect was no less than the greatness of his mind in
setting his hand to an edifice so noble and grand, which, although it is
in a place where it can be enjoyed but little by men in general, being
out of the way, yet is none the less marvellous in its site, and very
suitable for one who wishes at times to withdraw from the vexations and
tumult of the city. This edifice, then, has the form of a pentagon, and
is divided into four sets of apartments, without counting the front
part, where the principal door is; in which front part is a loggia forty
palms in breadth and eighty in length. On one side there curves in a
round form a spiral staircase, ten palms wide across the steps, and
twenty palms across the space in the centre, which gives light to the
staircase, which curves from the base to the t
