As Controls, three samples whose ages had been determined independently were also dated.The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.It was first displayed at Lirey in France in the 1350s and subsequently passed into the hands of the Dukes of Savoy.The results of this intercomparison are reported and discussed by Burleigh . Three samples, each ~50 mg in weight, were prepared from this strip.Following this intercomparison, a meeting was held in Turin in September-October 1986 at which seven radiocarbon laboratories (five AMS and two small gas-counter) recommended a protocol for dating the shroud. The samples were then taken to the adjacent Sala Capitolare where they were wrapped in aluminium foil and subsequently sealed inside numbered stainless-steel containers by the Archbishop of Turin and Dr Tite.
But the three laboratories undertook not to compare results until after they had been transmitted to the British Museum.
For example, it is doubt about whether one’s hands are sufficiently clean that leads one to engage in repetitive hand-washing rituals.
Early conceptions of OCD from the 19th century acknowledged this issue directly, in that OCD was often termed the “doubting disease.” It is this need for certainty, the need to eliminate doubt, that leads many people with OCD to perform repetitive behaviors, which are known as rituals.
Likewise, uncertainty about whether a stove has been turned off (and worry about potentially dire consequences) can underlie checking rituals.
Many different types of rituals involve reassurance-seeking behaviors.
