Definitely for deep readers interested in the history of esotericism, astrology, and alternative cosmologies.

German astrologer Reinhold Ebertin sets out the principles of what he called cosmobiology—a mid-twentieth-century attempt to synthesise astrology with astronomy, psychology, and statistical observation. 

Ebertin’s work sits within a particular postwar European tradition that sought to modernise astrology by stripping away mythological symbolism and replacing it with geometric and astronomical structures. The book outlines the technical foundations of the system: planetary cycles, angular relationships, midpoints, and their proposed correlations with human character and events.

Whether approached as a historical curiosity or as a technical manual for practitioners, the book offers a window into one of the more influential strands of twentieth-century astrological thought.
