Silent films depicting antiquity utilized a range of representational strategies to vividly reconstruct Graeco-Roman architecture, thereby facilitating a temporal transport for audiences to the ancient past. One of the most prominent techniques was monumentality, which was used to create impressive sets and reflected advancements in film technology. This approach became a recurring feature in many films of the 1920s. The main set for the silent epic Quo Vadis (1924) set in the reign of the emperor Nero was the monumental palace created for the exhibition Mostra dell'Agricoltura, dell'Industria e delle Arti Applicate (Exhibition of Agriculture, Industry, and Applied Arts) held in 1923 at the Galoppatoio inside the Villa Borghese gardens in Rome. The architect Armando Brasini-renowned for his eclectic style rooted in Fascist architecture-designed the exhibition spaces. Brasini’s work drew inspiration from ancient Roman and Italian Baroque architecture, incorporating elements that evoked the poetic quality of ruins, a hallmark of Giovanni Battista Piranesi’s visionary drawings. This article explores Brasini’s architectural contribution to the film, with a focus on the representation of Nero’s palace and examines his influence on the rise of a monumental aesthetic in silent films portraying antiquity.
