The keys of The Lost Symbol

Robert Langdon, the famous professor of symbology of Harvard, after his investigations in the "Da Vinci Code" and "Angels and Demons", comes back in "The Lost Symbol", Dan Brown's last book. 
In this last thriller, the professor is called to come to Washington by his friend Peter Salomon to talk about the esotericist origins of the American capital.
In Washington, Robert Langdon is welcomed by a strange character and discovers that his friend disappeared.
The race against time begins (twelve hours) to find his friend Peter Salomon changes to a true initiatory path: gathering tools, opening to knowledge, symbolic death.

The American author scatters the plot with symbols coming from the universe of Freemasonry and takes down many clichés important to anti masonry and in the fifty last pages, begins a true plea for this initiatory order (of which Dan Brown is not a member as he says).

In this presentation, to the writer and translator Arnaud D'Apremont, it is not about deciphering Dan Brown's work but to make understandable the use the author does of symbols and keys inspired by Freemasonry. 
It is also about showing obvious references to the key of Hiram by Robert Lomas and to bring a light accessible to everyone on this universe considered as secret.









What teachings can we draw from Dan Brown's book?
How to use it? Does he give a mistaken image of this fraternity? Can he be considered as a an entering door suitable to the world of Freemasonry?
Answer in this 39-minutes presentation where Arnaud D'Apremont reconciles with intelligence, esotericist knowledge and popular culture.
