The relics of the Passion presented at Notre-Dame Cathedral in Paris include a piece of the True Cross from Rome as delivered by Saint Helena, along with a Holy Nail and the Crown of Thorns. Saint John tells that, in the night between Maundy Thursday and Good Friday, Roman soldiers mocked Jesus by placing a thorny crown on his head (John 19:12). The crown is a circle of cane bundled together and held by gold threads. The thorns were attached to this braided circle, which measures 21 centimetres in diameter. The seventy thorns were reportedly divided up between the Byzantine emperors and the Kings of France.
