I will not say that this book is not interesting, but I consider a bit like a tote: We go from Leonardo da vinci, the Shroud of Turin, the Templars, the Cathars at Rennes le Chateau, Mary Magdalene, etc, etc ... The proposed theories are not necessarily all silly, but I had the impression of reading an inventory, which is not based on the "solid". Nevertheless, the authors have the merit of preventing the reader that the Gospels are not "Gospels of words" precisely and only for that, it may be worth the detour. For readers who wish to read by against the more serious, I recommend the books of Mordillat and Prior. Conclusion: Reading entertaining, nothing more.
