A: Reichenau, Reichenau, Baden-Württemberg, Germany
A spectacular book-shaped reliquary preserved at the Cleveland Museum of Art has been attributed to the circle of the master manuscript illuminator, known as the Master of the Registrum Gregorii, who was active at Reichenau in the late 10th century. The metalwork reliquary incorporates an ivory plaque set within a frame of gilt silver, gems, and pearls on a core of wood. It measures 31.6cm x 24.4cm x 7.5cm. In February 2014 images were available from the Cleveland Museum of Art website at this link.
