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").
Crucifixion
The New Testament writings about the crucifixion of Jesus do not specify the shape of that cross, but the early writings that do speak of its shape liken it to the letter T. William Barclay notes that, because the letter T is shaped exactly like the "crux commissa" and because the Greek letter T represented the number 300, "wherever the fathers came across the number 300 in the Old Testament they took it to be a mystical prefiguring of the cross of Christ". The earliest example, possibly of the late first century, is the Epistle of Barnabas. Clement of Alexandria (c. 150 – c. 215) is another early writer who gives the same interpretation of the numeral used for 300. Justin Martyr (c. 100–165) sees the cross of Christ represented in the crossed spits used in roasting the Passover Lamb: "That lamb which was commanded to be wholly roasted was a symbol of the suffering of the cross which Christ would undergo. For the lamb, which is roasted, is roasted and dressed up in the form of the cross. For one spit is transfixed right through from the lower parts up to the head, and one across the back, to which are attached the legs of the lamb."
