Plotting the Centre: Bramante’s Drawings for the New St. Peter’s Basilica

Abstract

This paper examines the concept of 'centre' in the design and symbolism of the new St Peter's Basilica, executed by Donato Bramante in the early 16th century. Drawing upon theological and philosophical notions of centre in late Medieval and Renaissance culture (specifically Nicolas Cusanus), the study argues that Bramante's drawings for the project reveal a particular understanding of centre, and its constellations of sub-centres, that broadly follow Platonic cosmological principles highlighted in the Timaeus. The paper considers how this understanding of space was also communicated in the iconography of the frescoes in the Stanza della Segnatura in the Vatican Palace, executed by Raphael at the same time as Bramante's design for the new basilica, in which Bramante is also credited as the author of the perspective construction.
