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.
Longinus
The name is probably Latinized from the Greek "lonche" (λόγχη), the word used for the lance mentioned in John 19:34. It first appears lettered on an illumination of the Crucifixion beside the figure of the soldier holding a spear, written, perhaps contemporaneously, in horizontal Greek letters, , in the Syriac gospel manuscript illuminated by a certain Rabulas in the year 586, in the Laurentian Library, Florence. The spear used is known as the Holy Lance, and more recently, especially in occult circles, as the "Spear of Destiny", which was revered at Jerusalem by the sixth century, although neither the centurion nor the name "Longinus" were invoked in any surviving report. As the "Lance of Longinus", the spear figures in the legends of the Holy Grail.
