The Eye in the Pyramid

Illuminatus! is the first book in a trilogy, but it can be read as a standalone work. While subsequent books continue some themes and characters, this volume offers a complete narrative experience.

The authors drew heavily from real-world conspiracy theories, counterculture movements of the 1960s, and esoteric philosophies. Discordianism, a parody religion, is a significant influence on the book's themes and structure.

Yes, there was a notable stage adaptation of The Illuminatus! Trilogy by Ken Campbell, first performed in 1976 at the Liverpool School of Language, Music and Art, and later at the National Theatre in London.
