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.
Crown of thorns
According to three of the synoptic Gospels, a woven crown of thorns was placed on the head of Jesus during the events leading up to the crucifixion of Jesus. It was one of the instruments of the Passion, employed by Jesus' captors both to cause him pain and to mock his claim of authority. It is mentioned in the gospels of Matthew ('And when they had platted a crown of thorns, they put it upon his head, and a reed in his right hand: and they bowed the knee and mocked him, saying Hail, King of the Jews!' 27:29 KJV), Mark (15:17), and John (19:2, 5) and is often alluded to by the early Church Fathers, such as Clement of Alexandria, Origen, and others.
