"This book provides a rich, compelling, and vivid account of the careers of three Roman curialists: Agostino Patrizi, Johann Burchard, and Paris de’ Grassi. [...] The Office of Ceremonies provides a valuable foundation for future studies of papal ceremony and the Renaissance papacy." - Elizabeth M. McCahill, University of Massachusetts Boston, in: Renaissance Quarterly, Vol. 76, No. 4 (Winter 2023), pp. 1521–1522
