From The Times: Age of shroud of Turin disputed again.

A leading expert on the shroud of Turin has won the support of an Oxford University laboratory for new carbon dating tests on the venerated but controversial relic, which was dismissed two decades ago as a fake.

Carbon dating tests carried out in 1988 indicated that the shroud, long revered as the winding-sheet in which the body of Jesus was wrapped for burial and bearing his imprint, had been made between 1260 and 1390.

The Catholic church admitted at the time that the shroud could not be authentic.

John Jackson, a physicist at Colorado University and a prominent expert on the relic, has argued that the tests were skewed by 1,300 years because of high levels of carbon monoxide. He said many other elements of the shroud, including details of the image, indicate that it is much more ancient. [continue]
