Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Illuminatus! Trilogy is a series of three novels written by Robert Shea and Robert Anton Wilson first published in 1975. The trilogy is a satirical, postmodern, science fiction-influenced adventure story; a drug-, sex- and magick-laden trek through a number of conspiracy theories, both historical and imaginary, which hinge around the authors' version of the Illuminati. The narrative often switches between third and first person perspectives and jumps around in time. It is thematically dense, covering topics like counterculture, numerology and Discordianism. The trilogy comprises The Eye in the Pyramid, The Golden Apple and Leviathan. They were first published as three separate volumes starting in September 1975. In 1984 they were published as an omnibus edition, and are now more commonly reprinted in the latter form.
