8. The Bloodstains Are Human Blood
Many skeptics regarding the Shroud of Turin’s authenticity have long claimed that the image seen on the linen cloth is nothing more than a figure that an artist painted. In 1978, scholar John Jackson got permission from the Cathedral of Saint John the Baptist to carry out tests to determine what kind of paint may have been used. What he found when he tested pieces of the cloth is that no binding or mixing agents were used in the color, meaning that it did not correspond with the known painting practices of the fourteenth century. In fact, what was used to create the image on the shroud wasn’t paint at all. It was blood.
Jackson’s truly astounding find, though, was that it was human blood on the shroud. The blood type has been identified as type AB. Furthermore, there are two distinctive types of blood found on the cover: pre-mortem blood, the kind before a person dies, and post-mortem, which has undergone changes following death. If the Shroud of Turin indeed is a Medieval forgery, as the carbon-14 tests show, it is genuinely the most elaborate forgery of the entire Middle Ages, perhaps in world history. However, Jackson’s findings indicate that there may have been errors in the 1988 tests.
