Holy Blood Holy Grail by Michael Baignet, Richard Leigh & Henry Lincoln

What if everything we thought we knew about the origins of Christianity was wrong? In Holy Blood, Holy Grail, three investigative authors explore ancient documents, secret societies, and hidden symbols to put forth a radical theory: that Jesus Christ may have had descendants, and that a secret bloodline has been protected by powerful groups for centuries.
Drawing connections between the Knights Templar, the Priory of Sion, the Merovingians, and coded messages in art and architecture, this nonfiction book blends historical research with bold speculation. Controversial and influential, it inspired Dan Brown’s The Da Vinci Code and has sparked decades of debate.
