Here's what the book says about the Priory:
* Purpose: The Priory's primary mission is to protect the truth about Jesus and Mary Magdalene's relationship and their descendants. They believe that the Catholic Church suppressed this truth to maintain its power.
* Membership: The Priory is said to have been a secret society with influential members throughout history, including Leonardo da Vinci, Isaac Newton, and Victor Hugo.
* Secrets: The Priory hides its secrets within works of art, architecture, and other cultural artifacts. The book presents a puzzle that leads to clues about the Priory's existence and their true identity.
* Connection to the Grail: The Priory is said to guard the Holy Grail, but the book suggests that the Grail is not a physical object, but rather a metaphor for Mary Magdalene's bloodline.
Important Note: The Priory of Sion is a fictional creation by Dan Brown. Although the book claims it is a real historical organization, there is no evidence to support this claim. Historians and researchers have debunked the Priory of Sion as a hoax.
The Da Vinci Code's Impact: Despite its fictional nature, the book sparked considerable public interest in the Priory of Sion and the possibility of Jesus and Mary Magdalene's secret lineage. However, it is important to remember that the book is a work of fiction and not a factual account.
