This book investigates the esoteric and occult interpretations of Britain's prehistoric past, challenging conventional historical narratives. Comyns Beaumont, an author known for his explorations into hidden histories and ancient mysteries, presents a compilation of theories regarding a lost, advanced civilization in prehistoric Britain. The work draws upon a variety of sources, including mythological accounts, archaeological anomalies, and esoteric traditions, to construct an argument for a much older and more complex history than is commonly accepted. The book is structured into three parts, each delving into different facets of this hidden past, from cataclysmic events to the cults of ancient peoples.

This work is positioned within the realm of esoteric and alternative history, appealing to readers interested in occult interpretations of the past. The detailed table of contents suggests a comprehensive, albeit speculative, exploration of ancient British mysteries. Its approach is characteristic of authors who seek to uncover hidden knowledge beyond mainstream academic consensus, offering a unique perspective on prehistoric civilizations.
