Talisman is a roller-coaster intellectual journey through the back streets and rat runs of history to uncover the traces in architecture and monuments of a secret religion that has shaped the world. The story takes us from Heliopolis to Luxor, Alexandria, Toulouse, Florence, Rome, Paris, London, Washington DC, New York, and finally to the global pandemonium following September 11, 2001. It is a tale filled with romance and intrigue, heroism and faith, peopled by ancient Egyptian astronomer-priests, Christian Gnostics, Hermetic sages, learned Jews, Arab savants, Occitan counts, Cathar “perfects,” Knights Templar, Renaissance magi, Rosicrucian “invisibles,” Bavarian Illuminati, and Freemasons.
