A commonly held view of the Shroud of Turin is that is is a medieval forgery that originated around 1390 AD.
“Today, the bulk of evidence indicates that the Shroud originated sometime around the Middle Ages, and was created by human hands.”

“The History of the Shroud of Turin begins in the year 1390 AD, when Bishop Pierre d’Arcis wrote a memorandum where he charged that the Shroud was a forgery.”

“we can be virtually certain that the Shroud of Turin is a hoax that was originally created in France in around the 1350s AD by an artist trained in the Gothic figurative style as part of a faith-healing scam.”

The primary evidence for a medieval origin is C-14 dating which 3 labs date it in the 13th – 14th century.
“In 1988, scientists carbon-dated the shroud’s origins to between A.D. 1260 and 1390, supporting claims that it is merely a hoax.”

Later, I’ll go into detail about the C-14 dating. But, first I want to argue why it’s highly unlikely to be created from a medieval forger then challenge the C-14 dating.
