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").
Crown of thorns
According to three of the synoptic Gospels, a woven crown of thorns was placed on the head of Jesus during the events leading up to the crucifixion of Jesus. It was one of the instruments of the Passion, employed by Jesus' captors both to cause him pain and to mock his claim of authority. It is mentioned in the gospels of Matthew ('And when they had platted a crown of thorns, they put it upon his head, and a reed in his right hand: and they bowed the knee and mocked him, saying Hail, King of the Jews!' 27:29 KJV), Mark (15:17), and John (19:2, 5) and is often alluded to by the early Church Fathers, such as Clement of Alexandria, Origen, and others.
