e in the preparation of his
designs. And these Antonio executed with such accuracy and precision
that Bramante, finding that they were correct and true in all their
measurements, was constrained to leave to him the charge of a great
number of works that he had on his hands, only giving him the order that
he desired and all the inventions and compositions that were to be used
in each work. In these he found himself served by Antonio with so much
judgment, diligence, and expedition, that in the year 1512 he gave him
the charge of the corridor that was to lead to the ditches of the
Castello di S. Angelo; for which he began to receive a salary of ten
crowns a month; but the death of Julius II then took place, and the work
was left unfinished. However, the circumstance that Antonio had already
acquired a name as a person of ability in architecture, and one who had
a very good manner in matters of building, was the reason that
Alessandro, who was first Cardinal Farnese, and afterwards Pope Paul

in the Campo di Fiore, in which he lived with his family; and for that

At this time a church dedicated to S. Maria di Loreto was being built at
the Macello de' Corbi, near the Column of Trajan, in Rome, and it was
brought to perfection by Antonio, with decorations of great beauty.
After this, Messer Marchionne Baldassini caused a palace to be erected
from the model and under the direction of Antonio, near S. Agostino,
which is arranged in such a manner that, small though it may be, it is
held to be, as indeed it is, the finest and most convenient dwelling in
Rome; and in it the staircases, the court, the loggie, the doors, and
the chimney-pieces, are all executed with consummate grace. With which
Messer Marchionne being very well satisfied, he determined that Perino
del Vaga, the Florentine painter, should decorate one of the halls in
colour, with scenes and other figures, as will be related in his Life;
which decorations have given it infi
