Holy Lance
The Holy Lance in Vienna is displayed in the Imperial Treasury or "Weltliche Schatzkammer" (lit. Worldly Treasure Room) at the Hofburg Palace in Vienna, Austria. It is a typical winged lance of the Carolingian dynasty. At different times, it was said to be the lance of Saint Maurice or that of Constantine the Great. In the tenth century, the Holy Roman Emperors came into possession of the lance, according to sources from the time of Otto I (912–973). In 1000, Otto III gave Boleslaw I of Poland a replica of the Holy Lance at the Congress of Gniezno. In 1084, Henry IV had a silver band with the inscription "Nail of Our Lord" added to it. This was based on the belief that the nail embedded in the spear-tip was one that had been used for the Crucifixion of Jesus. It was only in the thirteenth century that the Lance became identified with that of Longinus, which had been used to pierce Christ's side and had been drenched in the Blood of Christ and water.
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)."
