This study employs network analysis and microhistory to challenge the standard narrative about architecture and patronage in Baroque Rome, that of celebrity patron-artist relationships. It investigates the artists and artisans below this elite team and the plurality of relationships that developed among them. The subject is Innocent X Pamphilj's monumental works of art and architecture, at the Vatican, Piazza Navona, Campidoglio, Lateran, and Janiculum Hill, commissioned for the 1650 Holy Year. It argues that competent artisans and their relationships influenced the operation of building sites and presents Innocent X as the patron of an industrious architectural enterprise.
