Saint Veronica holds up the cloth she is said to have offered Christ so he could wipe his sweaty face as he carried his cross to Golgotha. When he gave her hanky back, an image of his face was imprinted on it. A relic said to be the Sudarium survives in the Vatican. Much more famous in modern times is the Turin Shroud, said to show a complete image of Christ’s face and body, which photographic negatives gave a new lease of life in the 20th century. So try to see this painting as if it were the Shroud: ghostly “proof” of both the historicity and supernatural being of Christ. This smooth, forward-gazing, bearded image of Jesus was emulated by Renaissance artists in the belief it was miraculously accurate. Even Leonardo da Vinci created his own version of it in Salvator Mundi. National Gallery online. Don’t forget To follow us on Twitter: @GdnArtandDesign.
