Dynamic images of true, painted and reflected architecture (RBEG)

The Autumn Hall was created between 1687 and 1689 by Domenico Piola within a decorative project that involved the entire second noble floor in Palazzo Brignole Sale (Rosso), Genoa. The quadratura of the walls were realised by Antonio Haffner; the most engaging spatial effect, however, is on the vault with quadratura by Sebastiano Monchi representing of the myth of Bacchus and Ariadne. Surveys were conducted by integrating various techniques in order to acquire the necessary information to apply specific interpretative geometric methods to study the interaction between the true architecture and the painted architecture. Therefore, a number of optical tricks connected not only to perspective but also to the protruding elements and furniture were brought to light, thus demonstrating how these true and illusory spaces are inseparable and need to be analysed through different techniques of representation in order to reveal their complexity.
