A Queen's milestone: Professor Gauvin Bailey, Professor Matthew Reeve, and Emeritus Professor Pierre Du Preyare all contributors to the Cambridge Guide to the Architecture of Christianity, the two-volume magnum opus just published by Cambridge University Press (Cambridge: CUP, 2023). Out of 103 essay writers, these three Queen's Art History professors represent the highest number of contributors from a single institution, evidence of the Department’s depth in historical architecture and our internationally recognized scholarship. Congratulations, Profs. Bailey, Reeve, and Du Prey!
