Saint Longinus
The eponymous "carpenter" referred to in the lyrics is Jesus of Nazareth, who is said to have "carved his anchor on the dying souls of mankind". The tomb of the unknown soldier refers to the centurion Saint Longinus who acknowledged the dying Jesus as the Son of God and converted to Christianity before dying a martyr's death at the hands of Tiberius. The song seems to be sung from the perspective of Saint Veronica, Mary Magdalene, or the Virgin Mary as she "lay on the grass and observed her saviour" in his final moments.
