Foucault's Pendulum

Summary

Foucault’s Pendulum follows three Italian editors who work for a small publishing house specialising in obscure historical and occult manuscripts. As a private intellectual game, they begin inventing an elaborate conspiracy theory that connects secret societies, the Knights Templar, and centuries of hidden knowledge. Their fictional pattern gradually becomes more elaborate, drawing in real-world enthusiasts who believe the invented conspiracy reveals the truth about history. What begins as a playful exercise becomes increasingly dangerous as the editors lose control of the story they have created. Eco explores the human tendency to search for patterns and hidden meanings, showing how the desire to explain the world can lead people into irrational beliefs. Blending historical references, intellectual satire, and suspense, the novel examines conspiracy thinking, interpretation, and the dangers of confusing imaginative connections with evidence.
