Montréal – On the sidelines of the exhibition La Collection Torlonia. Chefs-d’œuvre de la sculpture romaine, a lecture titled Color: The Fourth Dimension of Sculpture will take place on Wednesday, April 8, at 6 PM at the Maxwell-Cummings Auditorium in Montréal. The lecture, by Paolo Liverani, professor of ancient topography at the University of Florence, will focus on research on polychromy in ancient sculpture, which has profoundly changed the way we perceive these works. Although reconstructions remain partially hypothetical, they help us better understand the role and function of art in ancient societies. The study of color is interdisciplinary: it combines the analysis of pigment traces on sculptures (conducted by archaeologists and restoration chemists), the reinterpretation of literary sources through philology and linguistics, and the contribution of cognitive sciences to understand the evolution of color terminology in ancient languages. Technical treatises from Late Antiquity and semiotic analysis also help interpret the social codes associated with colors. The lecture, organized by the Montreal Museum of Fine Arts in collaboration with the Italian Cultural Institute of Montréal, will present examples of works from archaic Greece to the early Byzantine period.
