Holy Lance
The name of the soldier who pierced Christ's side with a "lonchē" is not given in the Gospel of John, but in the oldest known references to the legend, the apocryphal Gospel of Nicodemus appended to late manuscripts of the 4th century "Acts of Pilate", the soldier is identified as a centurion and called Longinus (making the spear's Latin name "Lancea Longini").
Malchus
Malchus is the servant of the Jewish High Priest Caiaphas who participated in the arrest of Jesus as written in the four gospels. According to the Bible, one of the disciples, Simon Peter, being armed with a sword, cut off the servant's ear in an attempt to prevent the arrest of Jesus.
