This essay examines the history and decoration of the Salviati Chapel at San Gregorio al Celio in Rome as the repository of an image of the Virgin and in relation to two other chapels created by the same patron (Antonio Maria Salviati) in the church of San Giacomo in Augusta. In considering this dialogue among the chapels, I analyze the rationale behind the project at San Gregorio and its purpose to valorize antique images, reconstructing the particular design and function in the space of the now lost altarpiece with St. Gregory by Annibale Carracci. I also discuss more broadly th theme of the artistic experimentation and confrontation between "old" and "ruined" 'images' and "new" and "beautiful" 'works of art', that took place in Rome at the turn of the seventeenth century.
