Sangallo's ring of chapels takes light from the interior as Bramante planned it; and not only this, but he has provided no other means of lighting, and there are so many hiding-places, above and below, all dark, which lend themselves to innumerable knaveries, that the church would become a secret den for harbouring bandits, false coiners, for debauching nuns, and doing all sorts of rascality; and when it was shut up at night, twenty-five men would be needed to search the building for rogues hidden there, and it would be difficult enough to find them.

There is, besides, another inconvenience: the interior circle of buildings added to Bramante's plan would necessitate the destruction of the Paoline Chapel, the offices of the Piombo and the Ruota, and more besides.

I do not think that even the Sistine would escape." After this Michelangelo adds that to remove the out-works and foundations begun upon Sangallo's plan would not cost 100,000 crowns, as the sect alleged, but only 16,000, The material would be infinitely useful, the foundations important for the building, and the whole fabric would profit in something like 200,000 crowns and 300 years of time.

"This is my dispassionate opinion; and I say this in truth, for to gain a victory here would be my own incalculable loss."

His genius was responsible for the inharmonious window above the main entrance.
