1889. It should be kept in mind that at this time, late in Michelangelo’s life, he was entirely in charge of the rebuilding of Saint Peters. For this enormous labor he accepted no payment at all. The Vatican had for years, even centuries, been plagued by graft and corruption in its various huge building projects. A big church was looked upon as an endless source of income for architects, masons, and stone layers, and this tradition of never bringing to completion the big edifices goes back to the time of the cathedrals.
1890. It was the advent of Michelangelo that put an end to this problem. Perfectly pure and honest in himself, there was no way for anyone to take advantage of his position, and added to that, he could not be gotten around with false information or the exaggeration of problems because he was more knowledgeable about any of the work of his subordinates than they were.
1891. When jealous contemporaries attempted to criticize him to either the Pope or the Cardinals they turned a deaf ear to the critics, or turned them out altogether pointing out that Michelangelo was saving the church thousands of ducats every year, so it was pointless to level any criticism against him.
