Reliquary known as “the Small Book” in gold, enamel, pearls and rubies, crafted by French goldsmiths in the third quarter of the 14th century and housed in a gilt and enamel display case by Paolo di Giovanni Sogliani (1500-1501).

The reliquary itself is a small triptych with a fixed central portion and two hinged lateral leaves, hence its sobriquet. The relics of various saints are housed in small compartments on either side, while the center portion contains relics of the Passion of Christ, together with fragments of the Tablets of the Law and Moses’ rod. A small compartment on the upper portion of the triptych houses two miniatures on parchment: the first depicts Christ Crucified and mourners, the second the Trinity, Louis of Anjou and his wife Mary of Brittany. On the back an inscription explains that King Charles V gave this reliquary containing relics from Sainte Chapelle in Paris to his brother Louis of Anjou. In 1500 the Cloth Merchants’ Guild commissioned the large display case designed to house the reliquary and to display it in the Baptistery on the feast of Saint John on June 24 and the feast of Forgiveness on 13 January.
