Holy Lance
The name of the soldier who pierced Christ's side with a "lonchē" is not given in the Gospel of John, but in the oldest known references to the legend, the apocryphal Gospel of Nicodemus appended to late manuscripts of the 4th century "Acts of Pilate", the soldier is identified as a centurion and called Longinus (making the spear's Latin name "Lancea Longini").
Relics associated with Jesus
The relics of the Passion presented at Notre-Dame church 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.
