The same master, likewise, caused his young men to paint in the Church
of S. Giuseppe, near the Ripetta, the chapel of that church, which was
afterwards retouched and finished by himself; and he also had a chapel
painted after his designs in the Church of S. Bartolommeo in Isola,
which he retouched in like manner, and caused some scenes to be painted
at the high-altar of S. Salvatore del Lauro, with some grotesques on the
vaulting, and likewise an Annunciation on the facade outside, which was
executed by his pupil, Girolamo Sermoneta. Thus, then, partly because he
was not able, and partly because the labour wearied him, liking to
design his works rather than to execute them, he pursued the same course
that Raffaello da Urbino had formerly followed at the end of his life.
How harmful and how blameworthy is this practice, is proved by the Chigi
works and by all those carried out by other hands, and is also shown by
those that Perino caused to be executed in the same way; besides which,
those works of Giulio Romano's that he did not paint with his own hand
have not done him much honour. And although this method pleases Princes,
giving them their works quickly, and perhaps benefits the craftsmen who
labour upon them, yet, if they were the ablest men in the world, they
could never feel that love for the works of others which a man feels for
his own. Nor, however well drawn the cartoons may be, can they be
imitated as exactly and as thoroughly as by the hand of their author,
who, seeing the work going to ruin, in despair leaves it to fall into
complete destruction. He, then, who thirsts for honour, should do his
own painting. This I can say from experience, for after I had laboured
with the greatest possible pains on the cartoons for the Hall of the
Cancelleria in the Palace of S. Giorgio in Rome, the work having to be
executed with great haste in a hundred days, a vast number of painters
were employed to paint it, who departed so far from their outlines and
their true form, that I made a resolution, to which I have adhered, that
from that time onward no one should lay a hand on any works of mine.
Whoever, therefore, wishes to ensure long life for his name and his
works, should undertake fewer and do them all with his own hand, if he
desires to obtain that full meed of honour that a man of exalted genius
seeks to acquire.

I say, then, that Perino, by reason of the number of the labours
committed to his care, was forc
