This chasse served as a container for saints’ relics—often bones or pieces of cloth. The chasse depicts Christ in Majesty surrounded by saints on the lower front and the Lamb of God, emblematic of Jesus, flanked by angels on the sloping roof. Access to the sacred contents was through the locked door on one end. It shows Saint Peter, called by Jesus to be the keeper of the keys of heaven, as the guardian of the box’s holy relics.Note the wonderfully varied designs of the columns and the saints’ haloes, the exceptional translucent red, the scrolling pattern of the gilded ground, and the blue enamel that defines hair, brows, digits, and sinews. The design of the back simulates a costly silk textile.
