Shroud turin dating radiocarbon
Secondo Pia's 1898 negative of the image on the Shroud of Turin has an appearance suggesting a positive image.
It is used as part of the devotion to the Holy Face of Jesus. The shroud is rectangular, measuring approximately 4.4 by 1.1 metres (14 ft 5 in × 3 ft 7 in).
In 1532, the shroud suffered damage from a fire in a chapel of Chambéry, capital of the Savoy region, where it was stored.
There are some burn holes and scorched areas down both sides of the linen, caused by contact with molten silver during the fire that burned through it in places while it was folded.The cloth itself is believed by some to be the burial shroud that Jesus was wrapped in when he was buried after crucifixion.It is first securely attested in 1390, when a local bishop wrote that the shroud was a forgery and that an unnamed artist had confessed.Although there are numerous reports of Jesus' burial shroud, or an image of his head, of unknown origin, being venerated in various locations before the 14th century, there is no historical evidence that these refer to the shroud currently at Turin Cathedral.The history of the shroud from the 15th century is well recorded.
