The wall paintings in the former Refectory of the Trinità dei Monti convent in Rome: relating observations from restoration and archaeometric analyses to Andrea Pozzo’s own treatise on the art of mural painting

Abstract The paintings of Andrea Pozzo on the walls and vault of the Refectory in the Convent of Trinita dei Monti in Rome were recently restored. During this process, archaeometric research was carried out on the decorations. Using both restoration observations and the archaeometric analyses, the painting execution methods were examined and compared with Pozzo’s own recommendations in the appendix to his Treatise Perspectiva Pictorum et Architectorum (1693–1702).
