and enamel, the lower, larger one has two slivers of wood of the True Cross forming a cross. Around this on the central panel are enamel standing figures of Constantine on the left and Saint Helena (Constantine's mother who originally found the True Cross) on the right, below busts of archangels. An X-shaped fixture, with pearls at each of the four ends, holds the cross together. The insides of the wings contain four military saints: George and Procopius on the left, Theodore and Demetrius on the right. The outsides of the wings have figures of the Four Evangelists. The upper, smaller triptych held relics of the True Cross, Holy Sepulchre, and the robe of the Virgin Mary. The central panel has a Crucifixion with the Virgin Mary and Saint John the Evangelist standing beside the cross, with the sun and the moon above the cross. The insides of the wings have geometric decoration, while the outsides have an Annunciation to Mary. The outer wings of the main triptych contain enamel medallions with narrative scenes from the legends of the True Cross, stories well known in the Middle Ages. Over the top of the two top medallions is inscribed: Behold the Cross of the Lord, flee you hostile powers The Lion of the Tribe of Judah, the Root of David has conquered The three medallions on the left wing tell the story of Constantine's conversion to Christianity. Starting with the bottom medallion on the left wing, it pictures the medieval version of the legend of Constantine having a dream the night before the Battle of the Milvian Bridge, where he dreams an angel appears, points to the Cross, and tells him he will conquer under that sign. The middle medallion shows Constantine's victory at the Milvian bridge, with a cross standard. The upper medallion shows Constantine being baptized just before his death, by Pope Sylvester I, below an approving Hand of God. The three medallions on the right wing tell the story of Saint Helena's discovery of the True Cross. Starting with the bottom medallion on the right wing, Helena questions Jewish leaders (wearing Jewish hats) about the location of the Cross. In the middle medallion, Helena watches as servants dig up the Cross on Mount Calvary, below a pointing Hand of God; the two thieves crosses have already been excavated. In the upper medallion, Helena is testing the three crosses
