Abstract
This article discusses the foundation ceremony of the church of Sant’Ignazio di Loyola in Rome, the new chapel of the Collegio Romano. The ceremony was held in the Collegio’s existing smaller chapel, dedicated to the Annunziata, in 1626. The ceremony was led by the sponsor of the new church, Cardinal Ludovico Ludovisi, the nephew of the late Pope Gregory XV and one of the greatest art collectors of his time. The extraordinary apparato of the foundation ceremony focussed on the personifications of a wide range of artistic disciplines that exalted the patronage of Cardinal Ludovisi, as described in an anonymous contemporary pamphlet entitled Ragguaglio della solennita. It was an exercise in self-promotion and a failed attempt by Cardinal Ludovisi to regain some of the power he lost when Urban VIII succeeded his uncle as pope in 1623. The article will reconstruct the iconography of the apparato in relation to the texts on a set of commemorative medals, copies of which were deposited in the foundations and distributed among the attendees and reproductions of which were included in the apparato.
