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.
Holy Lance
The Holy Lance in Rome is preserved beneath the dome of Saint Peter's Basilica, although the Catholic Church makes no claim as to its authenticity. The first historical reference to the lance was made by the pilgrim Antoninus of Piacenza (AD 570) in his descriptions of the holy places of Jerusalem, writing that he saw in the Basilica of Mount Zion "the crown of thorns with which Our Lord was crowned and the lance with which He was struck in the side". A mention of the lance occurs in the so-called "Breviarius" at the Church of the Holy Sepulchre. The presence in Jerusalem of the relic is attested by Cassiodorus (c. 485–585) as well as by Gregory of Tours (c. 538–594), who had not actually been to Jerusalem.
