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").
Instrument of Jesus' crucifixion
With regard to the "primary" or "original" meaning of the Greek word σταυρός, William Edwy Vine (1873–1949) wrote in his "Expository Dictionary of New Testament Words", published in 1940: ""stauros" denotes, primarily, 'an upright pale or stake'. On such malefactors were nailed for execution. Both the noun and the verb stauroo, 'to fasten to a stake or pale', are originally to be distinguished from the ecclesiastical form of a two beamed cross". He said the shape of the ecclesiastical form of a two-beamed cross "had its origin in ancient Chaldea, and was used as the symbol of the god Tammuz (being the shape of the mystic Tau, the initial of his name) in Chaldea and nearby lands, including Egypt". He added that third-century churches, which by then had departed from certain doctrines of the Christian faith, accepted pagans into the faith in order to increase their prestige and allowed them to retain their pagan signs and symbols. "Hence the Tau or T, in its most frequent form, with the cross-piece lowered, was adopted to stand for the 'cross' of Christ." This association of the cross symbol with Tammuz had already been made by Abram Herbert Lewis in his 1892 book "Paganism Surviving in Christianity".
