SPOILERS! SPOILERS! BLAH BLAH BLAH!
Let's just suppose that everything in the book is true. Did any of the book's fans, believing the content to be true, stop to ponder the content? Okay, so we know that da Vinci was extremely intelligent and his puzzles were terribly clever, but to what end? What if he had devoted his mind to something useful instead of freaking cryptograms and other board game type material?
The notion that the Catholic church would go to such great lengths to suppress the "grail" is just retarded. The age and authenticity of ancient documents can be scientifically verified, but the content cannot and is therefore easily descredited. If Jesus was married and was not the Messiah then what is the purpose for the Priory of Scion? Okay, so he is a descendant of King David. Why all the puzzles and killings and secret meetings and encrypted crap?
The other thing that just kills me is the way he bills the ancient religion of goddess worship as some kind of superior religion. Also, people going to the temples to **** the priestesses were going to **** some hawt chicks, not to commemorate the sacred feminine. The ancients were soooooooo much greater than us modern cavemen. Don't we just wish we could go back to the good old days!
