Shroud of Turin FAQ

. . . in referece to the wikipedia text, principle pieces of evidence in favor of identifying the shroud with the image of Edessa

As indicated elsewhere, another strong argument is provided: the evidence that the shroud was folded, as it is seen on a tenth century painting depicting the legend of the apostle Thomas presenting the cloth with a picture of Jesus' face to King Abgar of Edessa. This is an unusual "landscape" layout for a face on a piece of cloth.

Persistent creases on the cloth are revealed by raking light photography. These creases clearly show that the cloth was kept folded in a way that only the face was visible. By folding the cloth, doubled in fours (tetradiplon) that is exactly what results: a centered face of Jesus on a horizontal folded cloth as seen in a 10th century painting of Abgar V holding a picture that is odd for its horizontal shape as a portrait.
