Leviathan

The third and final volume of the Illuminatus! trilogy by Robert Shea and Robert Anton Wilson, first published by Dell in 1975. Dell split the novel into three books for commercial reasons, and Leviathan picks up the story in the middle of its fourth part and carries it through the fifth and the appendices.

The Illuminati's plan to "immanentize the eschaton" comes to a head at a Woodstock-style rock festival in Ingolstadt, Bavaria, where a mass sacrifice is meant to grant eternal life to a chosen few. Hagbard Celine and the Discordians, aboard his golden submarine, set out to stop it, and the crew then faces the Leviathan itself, an ancient pyramid-shaped sea creature.

Like the first two volumes, it is a satirical, nonlinear mix of conspiracy theory, science fiction and Discordian humour. Read The Eye in the Pyramid and The Golden Apple first.
