Foucault's Pendulum

Foucault's Pendulum is a novel by Umberto Eco concerning the popularity of conspiracy theories throughout time, as well as their presence as a form of pseudo-religion.

Told in the form of a kind of intellectual game, three friends compile a fictitious Plan which stretches throughout history and hopes to combine all conspiracy theories, also embracing unlikely opposites. The novel is an encylopedic work, moving critic and novelist Anthony Burgess to comment that it needed an index. Published in 1988, translated into English by William Weaver.
