The 2019 Josephine Waters Bennett Lecture: The Winged Eye at Work: Leon Battista Alberti Surveys Old St. Peter's

Abstract

Leon Battista Alberti based his treatise “On the Art of Building” on close examination of a great many buildings. His survey of Old St. Peter's was especially thorough. He not only investigated the structure, but also ransacked written sources to re-create the church's original décor and to reconstruct the ways in which early popes had celebrated Mass and delivered sermons. Like Lorenzo Valla, he offered a suggestive and polemical history of the church. His ideas seemingly shaped the ways in which Pope Pius II restored the basilica, and his example shows that serious efforts to trace the history of Christianity long predated the Reformation.
