While the Art Institute of Chicago’s ancient and Byzantine collection was off view during the construction of the Mary and Michael Jaharis Galleries of Greek, Roman, and Byzantine Art, numerous objects underwent extensive conservation. The following video chronicles the conservation processes used to prepare several ancient and Byzantine artworks for display, including the restoration of a Greek vase, the cleaning of Roman and Byzantine mosaics, the metallurgical analysis of a bronze sculpture, and the laser-cleaning of a marble statue. This video was produced with the generous support of a Long Range Fund grant provided by the Community Associates of the Art Institute of Chicago. It was created for LaunchPad, a program of digital interpretive materials that supplement the viewing of works of art on display in the Art Institute of Chicago’s galleries.
