Maurice Cotterell - Alternative History
I freely admit that I read a lot of rubbish and sometimes I even find it convincing, but this is one of the biggest pieces of crap I've ever read. To give it credit, I could barely manage to get past the first chapter, so it could be the greatest archaeological masterpiece of its time, but somehow I doubt it.

This guy shows how Mayan designs can be photocopied onto acetate and laid over one another to produce "coded messages". Talk about lateral thinking - did the Mayans actually have acetate, do you think? Or did was the prophecy that humans of the future would have acetate so they kindly coded our salvation into stone, knowing that we'd understand what to do with it.

And what does this have to do with the prophecy that "shook the Freemasons", you might ask? Who knows - it was enough of a struggle to get past the Mayans and their secret overhead projectors. Don't bother
