From the Telegraph:
He was back in the limelight later in the 1970s, when his research on the propensity for corpses to bleed was quoted in the controversy over the authenticity of the so-called Shroud of Turin. Barrowcliff gave an expert opinion in the case of Hans Naber, a German black marketeer and convicted fraudster, who claimed to have had a vision in 1947 in which Jesus told him He had survived the Crucifixion to rise again from the tomb.
Naber claimed too much blood was present on the shroud for it to have swathed a dead body. Corpses do not bleed, he asserted – or at least the large quantity of blood on the shroud did not correspond to the blood emissions from a typical corpse. In his eyes, the shroud proved that Christ had only been wounded.
But Barrowcliff had shown that bodies do indeed bleed after death for a time, and demonstrated that cuts on the back of the head of a corpse (comparable to the wounds made by the Crown of Thorns) "would bleed freely, continuously".
“So-called?” Are there no editors at the so-called Telegraph?
