As arranged by Sangallo the Younger, the façades were to comprise the superimposed orders; for which Michelangelo substituted his scheme of the Capitol Palaces--a single colossal order, surmounted by an attic. He thus gained dignity at the expense of scale; for although the huge pilasters are eighty-seven feet high, they look much smaller, while the windows between them, each twenty feet in height, give an impression to the eye of about half that size. There is a similar apparent dwarfing of size in the piers and engaged columns of the nave, which actually measure to the top of the entablature one hundred feet. And this necessitated a corresponding increase of the dimensions of the sculptured figures in the spandrels, which are twenty feet high, thus further overpowering the sense of height. The noblest feature of the interior is the magnificent barrel vault of the nave, while the surpassing grandeur of the whole edifice consists in Michelangelo’s dome. Like Brunelleschi’s it has an inner and an outer shell, and is constructed on sixteen ribs, which, however, are all visible internally. The chief difference is the elevation of the dome and drum upon a second and loftier drum, composed of coupled Corinthian columns and intervening windows. This design was an adaptation of those which had been made by Bramante and Sangallo the Younger. The former had suggested a peristyle of columns; the latter, two drums; and Michelangelo virtually combined the two. But, in doing so he conceived new proportions between the vertical parts of the drum and the curve of the dome, that give his design not only a superior majesty but also a superior lightness and airiness. S. Peter’s indeed, notwithstanding much extravagant, tasteless, and meretricious sumptuousness, due to Bernini and others, remains a stupendous monument to the genius of Michelangelo and Bramante and to the genius of the Italian Renaissance. It is the fit symbol of an age that gradually lost touch of the finer things of the spirit and grew to worship greatness, power, and pomp; that had all but discarded Christianity for Paganism. * * * * *
