Marbles and Metals in the Forum of Augustus in Rome: a Unitary Project and its Polychromy

The Forum of Augustus is characterized by a unitary programme of architectural and sculptural decoration, in which colour played a fundamental role. This contribution examines the complex network of polychromatic and material relationships between architectural elements, including walls, pavements, and sculptures, as well as their scenographic effects and the differences in colour application between interior and exterior contexts. In synthesizing the results of 25 years of polychromy research at the Forum of Augustus, it also highlights the multiple possibilities and techniques of colour coating on white marble (Lunense) surfaces. Last but not least, it touches upon the application and techniques of metal coatings as well as the role of metal statues in the polychromatic experience that is the Forum of Augustus.
