The Shroud of Turin

The Shroud of Turin (or Turin Shroud) is a linen cloth bearing the image of a man who appears to have suffered physical trauma in a manner consistent with crucifixion. It is kept in the royal chapel of the Cathedral of Saint John the Baptist in Turin, Italy. The origins of the shroud and its image are the subject of intense debate among scientists, theologians, historians and researchers.

Believers contend that the shroud is the cloth placed on the body of Jesus Christ at the time of his burial, and that the face image is the Holy Face of Jesus. Detractors contend that the artifact postdates the Crucifixion of Jesus by more than a millennium. Both sides of the argument use science and historical documents to make their case.

The image on the shroud is much clearer in black-and-white negative than in its natural sepia color. The striking negative image was first observed on the evening of May 28, 1898, on the reverse photographic plate of amateur photographer Secondo Pia, who was allowed to photograph it while it was being exhibited in the Turin Cathedral. The Catholic Church has neither formally endorsed nor rejected the shroud, but in 1958 Pope Pius XII approved of the image in association with the Roman Catholic devotion to the Holy Face of Jesus.

Various tests have been performed on the shroud, yet both believers and skeptics continue to present arguments for and against the validity of the tests. One of the contentious issues is the radiocarbon dating in 1988 which yielded results indicating that the linen fibers of the shroud were grown during the Middle Ages. Believers have since presented arguments against the 1988 carbon dating results, ranging from conflicts in the interpretation of the evidence, to fabric samples being taken from a non-representative corner, to additional carbon having been added via fire damage. Heated debate has ensued ever since.Brendan Whiting, 2006, The Shroud Story, Harbour Publishing, ISBN 064645725X

Both skeptics and proponents tend to have very entrenched positions on the cause of formation of the shroud image, (at times pitting science versus divine formation) which has made dialogue very difficult. This may prevent the issue from being fully settled to the satisfaction of all sides in the near future.Colin Evans, 2002 A question of evidence ISBN 0471440140 page 10Paul Vignon, 2002 The Shroud of Christ ISBN 1885395965 page 3
