Stephen Jones has added a new part to his Shroud of Turin series. He explains:
Here is "2.6. The other marks" (3): Dirt on foot and limestone, which is part 14 of my series, "The Shroud of Turin." The previous post in this series was part 13, "2.6. The other marks" (2): Poker holes." See the Contents page (part 1) for more information about this series. This page had previously been posted as part of a combined "Poker holes, dirt on foot and limestone" post, but I later expanded the `poker holes’ section, which made the post too long, so I decided to separate out the "dirt on foot and limestone" part and repost it, hence this post.
Dirt on foot In 1978 STURP (Shroud of Turin Project) members, husband and wife Roger and Marty Gilbert, while carrying out reflectance spectroscopy on the Shroud, discovered an unusual spectral signal from the heel of the right foot on the dorsal side and nowhere else on the Shroud. As we saw in "2.5. The bloodstains" there is a clear imprint of the right foot only and that only on the dorsal side of the Shroud. When the area was examined under a microscope, dirt particles could be seen deep between the threads. It is logical to find dirt on the foot of a man who wore sandals, as Jesus did (Mt 3:11; Mk 1:7; Jn 1:27), and who would have been barefoot before he was crucified. That the dirt is not a later contamination is shown by it being under the bloodstains on the foot. But the dirt is not easily seen with the naked eye, so no forger would have put it there. Therefore this is yet another problem for the forgery theory[§11].
The picture is from Jones’ blog. He provides this description: “bloodstains and image of the right foot, on the dorsal side of the Shroud: Shroud Scope: Durante 2002 Vertical. The heel is lower left.”
