Ok, we admit it, we are decidedly pro-Shroud because in our opinion the preponderance of evidence supports it. But in fairness to the opposition, the following links will let you hear their side as well.
Here is the text of a recent article in Biblical
Archaeological Review (BAR) that featured a story by Gary Vikan, "Debunking
the Shroud: Made by Human Hands". The article also features comments from Walter
McCrone. This link takes you to the original article as well as articles written
in response by various Shroud experts.
