The naked body of Jacques Saunière's , the Louvre's curator is the first image of the thriller.
In the center of the light, like an insect under a microscope, his corpse lay naked on the parquet floor.
Saunière had drawn a simple symbol on his flesh: five straight lines that intersected to form a five-pointed star.
This pentacle is representative of the female half of all things — a concept religious historians call the 'sacred feminine' or the 'divine goddess'.
The pentacle symbolizes Venus—the goddess of female sexual love and beauty.
The clarity of Saunière's intentions could not be denied. In his final moments of life, the curator had stripped off his clothing and arranged his body in a clear image of Leonardo da Vinci's Vitruvian Man.
The celebrated sketch consisted of a perfect circle in which was inscribed a nude male, his arms and legs outstretched in a naked spread eagle.
The circle had been the missing critical element. A feminine symbol of protection, the circle around the naked man's body completed Da Vinci's intended message—male and female harmony. The question now, though, was why Saunière would imitate a famous drawing.
Jacques Saunière's final communication seemed as unlikely a departing message
The message read:
13-3-2-21-1-1-8-5 O, Draconian devil! Oh, lame saint!
He also wrote to find Robert Langdon.
Robert Langdo, a Harvard University professor of religious iconology and "symbology", a fictional field related to the study of historic symbols.
So he is the right person at the right moment, as he can decipher the code.
Langdon was supposed to have a meeting with Jacques Saunière's the day of the murder and he became the first suspected person of the murder..
In his investigation, Landgon is helped by the beautiful Sophie, Jacques Saunière's nephew.
She is a French cryptologist.
Step by step, they arrived to discover that the Priory of Sion is the link of the story .
Da Vinci presided over the Priory between 1510 and 1519 as the brotherhood's Grand Master, which might help explain Jacques Saunière's passion for Leonardo's work. The two men shared a historical fraternal bond.
The identities of living Priory members were kept extremely secret, but the P.S. and fleur-de-lis that Sophie saw as a child were proof. It could only have been related to the Priory.
The fleur-de-lis... the flower of Lisa... the Mona Lisa. The Da Vinci she had grabbed, much like the Mona Lisa, was notorious among art historians for its plethora of hidden pagan symbolism. Jacques Saunière had indeed paid a visit to the Mona Lisa before he died and he wouldn't have come there without a reason.
And moreover, a thug from the secretive Catholic organization Opus Dei, under orders from a sinister bishop, is also trying to understand the meaning of the imaginative corpse in the museum.
The interpretation key of the thriller is focused on the Templars and on the Holy Grail, the cup used in the last supper by Jesus.
Holy Grail is the literal meaning of Sangreal.
It is not a cup at all. They claim the Grail legend—that of a chalice—is actually an ingeniously conceived allegory. That is, that the Grail story uses the chalice as a metaphor for something else, something far more powerful.
Something that fits perfectly with everything
Jacques Saunière's had been trying to tell them , including all his symbologic references to the sacred feminine.
The Holy Grail is arguably the most sought-after treasure in human history. The Grail has spawned legends, wars, and lifelong quests.
The legend is a legend about royal blood. When Grail legend speaks of the chalice that held the blood of Christ, it speaks, in fact, of Mary Magdalene—the female womb that carried Jesus' royal bloodline.
History is always written by the winners. When two cultures clash, the loser is obliterated, and the winner writes the history books—books which glorify their own cause and disparage the conquered foe.
The Sangreal documents simply tell the other side of the Christ story. In the end, which side of the story you believe becomes a matter of faith and personal exploration, but at least the information has survived.
The Grail story is everywhere, but it is hidden
You do not find the Grail, the Grail finds you.
Sophie sensed something deeply personal entwined within this mystery.
But which mistery?
From my point of view, the The da Vinci Code has to be seen simply as a work of fiction, an invention, a detective story, a murder story.
It is not an historical book and its only aim is that to maintain the readers' curiosity and in addition to this to rouse a personal reflection about Catholic and artistic world.
According to me, Angels and Demons, written before The da Vinci Code is much higher.
The skill of the author has been that to put together the myths and the legends around the theme of the Holy Grail and to elaborate them in a personal way, creating a story.
