I finally got the link to work and much to my dismay, got a long 'sermon' on the origin of Christianity, the Bible and assorted other Christian "facts". As a cynic, I view this scribe as I do the DaVinci Code; a hypothesis at best and a fiction at worst.
The likelihood of anyone proving this work is scant. However, this type of pseudo-history is popular at present (See 1421, Walking the Bible, etc).
