Is the Turin shroud genuine?
No, there are other problems, including: It makes no sense as a shroud: Who uses a shroud that closes at the head and is open at the feet. It does not match description of shroud in the Fourth Gospel (of course this assumes reliability of the Gospel account). Arms are an unnatural length. Shroud does not account for circumference of the top of the head. Gospels indicate that Jesus, who was accused of gluttony, was a heavyset man. Image depicted by shroud corresponds to European idealized view. The process by which the image could have been put on the shroud is familiar to any schoolchild who has ever done the “Invisible Ink” trick: Transfer the image to the cloth with a weak acid, allow to dry, then heat the cloth leaving brown scorchlike marks of the image.
