The Holy Lance, also known as the Spear of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, is alleged to be the lance that pierced the side of Jesus as he hung on the cross during his crucifixion. As with other instruments of the Passion, the lance is only briefly mentioned in the Christian Bible, but later became the subject of extrabiblical traditions in the medieval church. Relics purported to be the lance began to appear as early as the 6th century, originally in Jerusalem. By the Late Middle Ages, relics identified as the spearhead of the Holy Lance (or fragments thereof) had been described throughout Europe. Several of these artifacts are still preserved to this day.
Holy Lance relics have typically been used for religious ceremonies, but at times some of them have been considered to be guarantees of victory in battle. For example, Henry the Fowler's lance was credited for winning the Battle of Riade, and the Crusaders believed their discovery of a Holy Lance brought them a favorable end to the Siege of Antioch.
In the modern era, at least four major relics are claimed to be the Holy Lance or parts of it. They are located in Rome, Vienna, Vagharshapat and Antioch. The most prominent Holy Lance relic has been the one in Vienna, adorned with a distinctive gold cuff. This version of the lance is on public display with the rest of the Imperial Regalia at the Hofburg.
