A massive, golden shrine in Cologne Cathedral contains relics believed to be of the biblical Three Kings who brought gifts of gold, frankincense, and myrrh to the infant Jesus. The relics were acquired in Milan in 1164, and the goldsmith Nicholas of Verdun was commissioned to create one of the most ambitious reliquaries in Europe. This tiny arch, which comes from this important shrine, was removed during nineteenth-century restorations.
