de Charny, Lord of Savoisy and Lirey, founded at Lirey a collegiate church with six canonries, in honour of the Annunciation of the Virgin Mary, and in this church he exposed for veneration a Holy Shroud. Opposition arose on the part of the Bishop of Troyes, who declared after due inquiry that the relic was nothing but a painting, a fact to which the creator of the "relic" confessed. Therefore, the Bishop opposed its being exhibited. Clement VI, persuaded by interested parties, issued four Bulls on 30 January 1354, approving the exposition as lawful, and two more, on 3 August 1354 (granting indulgences) and 5 June 1357. In 1418 during the civil wars, the Canons entrusted the Winding Sheet to Humbert, Count de La Roche, Lord of Lirey. Margaret, widow of Humbert, never returned it but gave it in 1452 to the Duke of Savoy. The requests of the canons of Lirey were unavailing, and the Lirey shroud is claimed to be the same that is now on display in Turin. Revolution The diocese of Troyes was abolished during the French Revolution by the Legislative Assembly, under the Civil Constitution of the Clergy (1790). Its territory was subsumed into the new diocese, called the 'Aube', which was part of the Metropolitanate called the 'Metropole de Paris' (which included seven new 'départements'). The majority of clergy in the diocese of Troyes took the oath to the Constitution. The legitimate bishop, Louis-Mathias-Joseph de Barral, refused to take the oath, departed Troyes on 11 March 1791, and emigrated to Switzerland by way of Trier. Many of the non-jurors emigrated in September 1792, eighty-three of them seeking refuge in Switzerland. Those who were too old or ill were rounded up and incarcerated in the College of the Oratory. The diocesan seminary did not have enough teachers or students to continue to function; the building was used as a detention center for suspicious persons. In Switzerland, Bishop de Barral conferred with a number of his fellow exiles from the episcopal college, who came to the opinion that one might swear the Constitutional oath. Bishop de Barral left them and travelled to London, where he found the episcopal sentiment much more rigorous. Nonetheless, in 1791 he wrote a letter in which he approved the submission, though without blaming the recusants. In 1800 he declared himself for taking the oath. After Napoleon came to power on 18
