The history of the Shroud of Turin can be best studied by dividing it into two specific categories.
On the same date Clement writes a letter to Geoffrey II de Charny apparently restating the conditions under which expositions could be allowed.Margaret de Charny's half-brother Charles de Noyers negotiates compensation to the Lirey canons for their loss of the Shroud, which they specifically recognize they will not now recover. By an accord drawn up in Paris, Duke Louis I of Savoy agrees to pay the Lirey canons an annual rent, to be drawn from the revenues of the castle of Gaillard, near Geneva, as compensation for their loss of the Shroud.(This is the first surviving document to record that the Shroud has become Savoy property) The accord specifically notes that the Shroud had been given to the church of Lirey by Geoffrey de Charny, lord of Savoisy and Lirey, and that it had then been transferred to Duke Louis by Margaret de Charny. Just over two decades later a chronicle of Savoy will record his acquisition of the Shroud as his greatest achievement.This also happens to coincide with the approximate date determined by the 1988 carbon dating of the cloth.Although there is a significant amount of evidence supporting the Shroud's existence prior to the mid 1300's, much of it is, in fact, "circumstantial" and remains mostly unproven.
A completely detailed Shroud chronology can be found in the 1998 book titled "The Blood and the Shroud," by Ian Wilson, that includes the earlier, more speculative and "circumstantial" material as well.
