Shroud of Turin: Fact or Fiction? Discussion at Gilroy Library

The Shroud of Turin is arguably one of the world's most important artifacts. Join us on Tuesday, June 18th at 7pm when Mark Okuda leads a presentation detailing the method for aging artifacts including a hands on activity with linen samples and microscopes.

Three independent scientific labs yielded a calibrated calendar age range with at least 95% confidence that dated the linen of the Shroud of Turin around AD 1260 - 1390 (±10 yrs.). These results provided evidence that the Shroud of Turin was not the reported cloth that Jesus Christ was wrapped in after the crucifixion. This session will address how artifacts are aged and a take a closer examination of how the “official” age of the shroud might be in question.
