• Examines the Rosicrucian involvement of figures like Rene Descartes, Robert Fludd, John Dee, Elias Ashmole, and the alchemist pirate Prince Rupert of the Rhine

• Traces the saga of Rudolf II, Holy Roman Emperor, and his countercultural successors Frederick and Elizabeth, who triggered the Thirty Years’ War

• Shows how Rosicrucianism inspired the English Revolution and explores the Rosicrucianism of John Winthrop the Younger, Connecticut’s founder

Since the appearance of Rosicrucian manuscripts in 17th-century Germany, historians have questioned the authorship, intent, and significance of this esoteric movement. In this book, Ronnie Pontiac shows how Rosicrucianism’s underground influence in the early-modern period continues to the present, providing the important historical context of this invisible society.

Pontiac looks at the esoteric culture around Holy Roman Emperor Rudolf II and his court, including figures like John Dee, Tycho Brahe, and Rabbi Loew, the legendary creator of the Golem of Prague. Despite occultists’ fascination with Rudolf ’s successors, Frederick and Elizabeth, at the start of the Thirty Years’ War—and Rosicrucian efforts to make Frederick the first Protestant Holy Roman Emperor—the esoteric renaissance in Bohemia was short-lived. However, this wasn’t the end of Rosicrucianism.

Pontiac explores the movement’s impact on Oliver Cromwell and the English Revolution as well as individuals such as Robert Fludd, René Descartes, Elias Ashmole, Moritz the Learned, Paracelsus, and William Shakespeare. He then details the movement’s arrival in the New World, including the Rosicrucian activities of Connecticut’s alchemist governor, John Winthrop the Younger. Looking to the present, Pontiac shows how both pop culture and the modern psychedelic counterculture are informed by Rosicrucian ideas, showing the enduring legacy of this esoteric movement.
