A chasse is a reliquary casket shaped like a house or church, with a sloping roof and gabled ends, made to hold the bones of a saint. The best known are the enamelled chasses of Limoges, produced in huge numbers from the later 12th to the 13th century in champlevé enamel on gilded copper: scenes from the lives of saints - journeys, miracles, martyrdoms - fill the panels in jewel-colored registers beneath arcades. Some were wrought in silver or ivory, and the finest church treasuries across Europe prized them. As a form the chasse endured through the Gothic period, its narrative panels a compact encyclopedia of medieval devotion and workshop practice.
