After the release of the international bestseller 'the name of the rose' (1980), proslavlennoy famous film, Italian historian, aesthetician, structuralist Umberto Eco was in a difficult position. As a second time take a similar height? How to write no less a good book for different readers, and knowledgeable and inexperienced? The book is as alive as wise as sardonicous as gentle? The author took up the challenge and confirmed the previous record. 'Foucault's pendulum' (1988) has made not less than 'Name of the rose', and the film is not removed just because the author himself was not allowed to the great Stanley Kubrick. On these pages interact with the editors of the Milanese publishing house, knights-Templar, voodoo priests and antifascist partisans. Narrated by and about the legendary knights Templar, the secret masters of the world, but just to remind: the story credible when its basis is an indisputable document. The rest is a game. The game, which is dangerous.
