Quote:The known provenance of the cloth now stored in Turin dates to 1357, when the widow of the French knight Geoffroi de Charny had it displayed in a church at Lirey, France (diocese of Troyes). In the Museum Cluny in Paris, the coats of arms of this knight and his widow can be seen on a pilgrim medallion, which also shows an image of the Shroud of Turin.
During the fourteenth century, the shroud was often publicly exposed, though not continuously, since the bishop of Troyes, Henri de Poitiers, had prohibited veneration of the image. Thirty-two years after this pronouncement, the image was displayed again, and King Charles VI of France ordered its removal to Troyes, citing the impropriety of the image.
The sheriffs were unable to carry out the order.In 1389 the image was denounced as a fraud by Bishop Pierre D'Arcis in a letter to the Avignon pope, mentioning that the image had previously been denounced by his predecessor Henri de Poitiers, who had been concerned that no such image was mentioned in scripture. Bishop D'Arcis continued, "Eventually, after diligent inquiry and examination, he discovered how the said cloth had been cunningly painted, the truth being attested by the artist who had painted it, to wit, that it was a work of human skill and not miraculously wrought or bestowed." (In German.) The artist is not named in the letter.
