I also read somewhere that the Priory, as it's described in the Da Vinci Code, for example, is bogus. It might exist somewhere, but they're probably not the keepers of the Holy Grail, whatever it may be.

This Holy Grail business is a puzzle that will likely never be solved, but I do believe that it is so much more than a simple cup. I also believe in the interpretation of 'sang raal' (royal blood) instead of 'san graal' (holy grail) but that's just me. These are the problems because people who wrote over a thousand years ago didn't put spaces or lowercase letters when they wrote.
