Holy Lance
The Holy Lance, also known as the Lance of Longinus (named after Saint Longinus), the Spear of Destiny, or the Holy Spear, according to the Gospel of John, is the lance that pierced the side of Jesus as he hung on the cross.
Instrument of Jesus' crucifixion
In language very similar to that of Minucius Felix, Tertullian, too, who distinguished between "stipes" (stake) and "crux" (cross), noted that it was the cross that people associated with Christianity. And he indicated that the shape of the cross is that of the letter T: "The Greek letter Tau and our own letter T is the very form of the cross, which (God) predicted would be the sign on our foreheads", and compared it to the shape of a bird with outstretched wings.
