additional proof of the inaccuracy of the 1988 Carbon 14 dating due to mending?
Joe Marino sends along this passage from The Untold Story of the Holy Shroud by Carlos Evaristo (2011). The book contains information from the Savoy family archives that has otherwise never been publically disclosed:
According to King Umberto II, the pious practice of sharing Major Relics of the Holy Shroud was, according to tradition, continued by the first three Savoy Lords who possessed it, although they, unlike some of their predecessor Guardians, never purposely removed fragments from their areas with the image of the Corpus Sancti (Holy Body.)
Another fact confirmed by His Majesty was that it was traditionally affirmed, that at one point in the past, the edges of the Lenzuoli (Sheet) had become so tattered as to cause embarrassment or criticism of the Custodians, and those areas were repaired and rewoven using identical techniques, but obviously with similar, yet newer, materials containing dyes and other medieval manufacturing ingredients, in an attempt to better blend the new sections in, as best possible, with the original fabric.
In truth, the presence of medieval dyes was detected in these areas and this fact has been already pointed out by Scientists as additional proof of the inaccuracy of the 1988 Carbon 14 dating test results that placed the samples taken from these areas, as having been fabricated sometime in the middle ages.
In truth, any one of the aforementioned practices alone would also account, for not only the contamination of the fabric resulting in inaccurate Carbon 14 dating results, but also, the different types of linen, dyes, resins and fabric patches, discovered to have been present on the outermost edges of the sheet that usually held by Bishops during the exposition of the Sacred Relic to the public for veneration.
