Question

What is the priory of Sion according to Dan Brown?

Answer 1

a group of men who guarded the holy grail  

Answer 2

check out Holy Blood+ Holy Grail by Michael Baigent, Richard Leigh, and Henry Lincoln.

Basically, this is the book that Dan Brown cribbed his book from, fi thee authors hadn't claimed it was all true, they'd be the multi-millionaires now.

Answer 3

He found the idea in a previous book written about the templars and the grail legend. The priory did not exist nor has it ever existed being the fantasy of an Frenchman who even had his picture taken with his grandson to prove that he was in the line of succession of the Merovingian kings.

  I can tell you quite candidly that there is no connectiion between the templars and the priory of Sion. If you are interested, look up the Brotherhood of the Holy City, which meets in Belgium twice a year.

Answer 4

the priory of sion is a secret brotherhood that protects the family lineage of jesus christ and the sarcophagus of mary magdalene....dan brown wrote his book, the davinci code, claiming that there is a brotherhood that protects all these secrets, including the holy grail and the holy grail documents.
