""Jenn Zahrt's fluent translation is part of a wider study of astrology in the German-speaking world in the early twentieth century, making texts available in English as part of this project. Ebertin's book can be treated as a significant primary source, important for historians, but it is also part of a living tradition, and to be recognised as such. Its publication is welcome."" -Nicholas Campion, Programme Director MA Cultural Astronomy and Astrology, University of Wales Trinity Saint David, August 2024
