According to an inventory of 1482, this life-sized reliquary originally enshrined an arm bone of Saint Babylas, a bishop of Antioch martyred around 250 A.D. The object was designed for the relic to sit in the hollow chamber and be visible through the latticework door. Traditionally, vessels for relics were often made in forms appropriate to the sacred objects they contained. Here the hand, rendered in the naturalistic style of the late fifteenth century, makes a clear gesture of blessing, an activity associated with bishops that implies their benevolent communication with the faithful. This is one of a dozen arm reliquaries once part of the Guelph treasure, an important medieval sacral collection of over 140 relics and liturgical objects that was kept for centuries at the cathedral of Saint Blaise at Brunswick, Germany, until it was dispersed in the 1930s.
