Note 39 — Chapter IV · THE DOME OF ST. PETER’S

Serlio, the architect (a younger contemporary of Bramante), _op. cit._, p. 33, tells us that Bramante, at his death, left no perfect model of the whole edifice, and that several ingenious persons endeavoured to carry out the design, among whom were Raphael and Peruzzi, whose plans he reproduces. That ascribed to Raphael has a long nave, while that said to be by Peruzzi has the form of the Greek cross with round apses and a square tower in each external angle. The whole question of Bramante’s scheme, and of the successive transformations to which the design for the edifice was subjected before its final completion, is fully discussed in the work of Baron H. von Geymüller, _Die ursprünglichen Entwürfe für Sanct Peter in Rom_, Wien and Paris, 1875–1880.
