Longinus in the context of "Crucifixion of Christ"

Jesus was put to death by being nailed on an execution device made by the Romans, commonly named as a cross (Latin: crux). The instrument of crucifixion is taken to be an upright wooden beam to which was added a transverse wooden beam, thus forming a "cruciform" or T-shaped structure. His crucifixion occurred in 1st-century Judaea, most likely in AD 30 or AD 33. The event is described in the four canonical gospels, referred to in the New Testament epistles, and later attested to by other ancient sources. Scholars nearly universally accept the historicity of Jesus' crucifixion, although there is no consensus on the details. According to the canonical gospels, Jesus was arrested and tried by the Sanhedrin, and then sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans.

Jesus was stripped of his clothing and offered vinegar mixed with myrrh or gall (likely posca) to drink. At Golgotha, he was then hung between two convicted thieves and, according to the Gospel of Mark, was crucified at the third hour (9 a.m.), and died by the ninth hour of the day (at around 3:00 p.m.). During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" which, according to the Gospel of John, was written in three languages (Hebrew, Latin, and Greek). They then divided his garments among themselves and cast lots for his seamless robe, according to the Gospel of John. The Gospel of John also states that, after Jesus' death, one soldier (named in extra-Biblical tradition as Longinus) pierced his side with a spear to be certain that he had died, then blood and water gushed from the wound. The Bible describes seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred.

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.
