text: what did you learn about the priory of sion, or leonardo davinci from reading the da vinci code?   i learned a lot about those subjects by reading the da vinci code and in turn, researching the subjects i read about in the book and plan on doing much more research about those subjects.  i just finished reading the prequal to the da vinci code "angels & demons" and plan on reading "holy blood, holy grail" (non fiction book by a different author on the same subjects) to learn more.
