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").
Instrument of Jesus' crucifixion
Like the Epistle of Barnabas, Justin saw the stretched-out hands of Moses in the battle against Amalek as foreshadowing the cross of Jesus: "If he gave up any part of this sign, which was an imitation of the cross (σταυρός), the people were beaten, as is recorded in the writings of Moses; but if he remained in this form, Amalek was proportionally defeated, and he who prevailed prevailed by the cross (σταυρός). For it was not because Moses so prayed that the people were stronger, but because, while one who bore the name of Jesus (Joshua) was in the forefront of the battle, he himself made the sign of the cross (σταυρός)."
