.- A physics professor has persuaded an Oxford laboratory to revisit the question of the age of the Shroud of Turin, the reputed burial shroud of Jesus Christ.The professor argues that carbon monoxide contaminating the shroud could have distorted its radiocarbon dating results by more than 1,000 years.Jackson must prove a viable pathway for carbon monoxide contamination.He is working with Oxford to test linen samples subjected to various conditions the shroud has experienced, including outdoor exhibitions and exposure to extreme heat during a fire in 1532.The bishop recalled that during Henry of Poitiers’ investigation “Many theologians and other wise persons declared that this could not be the real shroud of our Lord having the Saviour's likeness thus imprinted upon it, since the holy Gospel made no mention of any such imprint, while, if it had been true, it was quite unlikely that the holy Evangelists would have omitted to record it, or that the fact should have remained hidden until the present time.” Some modern commentators, however, have dismissed Bishop d’Arcis’ comments as nothing more than jealousy and synthetic outrage.Perhaps more difficult to dismiss than medieval bishops was the evidence of 20th Century scientists from the University of Oxford, the University of Arizona and the Swiss Federal Institute of Technology, who were allowed to carbon date samples of the shroud in 1988.Ramsey said that other forensic and historical evidence indicates the shroud is much older than radiocarbon dating results initially indicated."Science still has much to tell us about the shroud," said Jackson, a devout Catholic who heads the Colorado Springs-based Shroud of Turin Center.
A positive image of the shroud was produced only with the arrival of modern photography.
But it was while it was in France, soon after the start of what is sometimes called its “undisputed”, or documented history, that Bishop d’Arcis became one of the first people to express doubts about the 4.4 m (14ft 5in) long and 1.1 m (3ft 7in) wide piece of linen cloth.
Writing in 1390, the bishop said that the cloth first started attracting pilgrims in 1355 when it was in the possession of the Geoffrey de Charny, a French knight building a church at Lirey to give thanks to God for a miraculous escape from English imprisonment during the Hundred Years War.
There is no consensus regarding what medieval methods, if any, could have created the shroud.
Though the Vatican keeps the shroud locked in a protective chamber at the Cathedral of St.
