Is Priory of Sion an elaborate hoax??

real

it's not even all that elaborate, actually!

How so? Please clarify.

The paper trail started in the 50's.

I think it's simply a project of an imaginative wanna-be with way too much time on his hands.

Any of the "DaVinci Code Debunking" documentaries, books, etc. have covered the ground thoroughly.

Dan Brown is a novelist. His stories entertaining, but a major rip-off from the works of others.

It's all only fiction. Been keeping conspiracy theories going.

Have you thought about a possibility that it might be a diversion for something else?

I mean why Plantard took things too far that he eventually lost the control of it?

and...?
