Book excerpt: There is scant research on the art produced under the Congregation of the Oratory of Saint Philip Neri, with the exception of a couple of general books focused primarily on major Oratorian art pieces. Therefore, this book of essays aims to discuss the art and culture produced by or associated with the Oratorians by providing a broad overview focused especially on rarely investigated issues. The authors focus on this very important artistic production, commonly forgotten when compared with other religious productions of art, by covering geographical areas spanning from Sri Lanka to Mexico, including Italy, Spain, the United Kingdom, India and Brazil.
