Our authorities for this episode in Michael Angelo's biography are mainly Vasari and Condivi. Though there may be exaggeration in the legend, it is certain that a correspondence took place between the Pope and the Gonfalonier of Florence, to bring about his return. See Heath Wilson, pp. 79-87, and the letter to Giuliano di San Gallo in Milanesi's Archivio Buonarroti, p. 377. Michael Angelo appears to have had some reason to fear assassination in Rome.
