Abstract

It would be hard to find a more effective visual source for understanding the political ideology that underscores Dante's relationship to Boniface VIII in the Divina Commedia than the frescoes that line the walls of the Oratorio di San Silvestro in the Basilica of the Santi Quattro Coronati in Rome. These frescoes, which depict episodes from the life of St. Sylvester and his relationship to the emperor Constantine, express as their clear subtext the thirteenth-century papacy's view of the proper relationship between ecclesiastical and secular power . Their vivid dramatization of these events synthesizes and, more importantly, interprets two well-known literary sources: the life of St. Sylvester that was thought to have been composed by Eusebius of Caesarea and the text of the Donation of Constantine, the Constitutum Constantini. The account of the life of St. Sylvester that is contained in the Golden Legend also provides a readily accessible point of reference for the cycle, since it is roughly contemporaneous with it and is itself a compilation based on these earlier texts
