"Mundane astrology is the oldest and most complex branch of the art. It is notoriously difficult, as it requires its practitioners to have a handle not only on a specialized set of astrological techniques but also on the social studies of history, geography, civics & economics. Because of this, it is considered by many to be the capstone of the astrological edifice. John Michael Greer's The Astrology of Nations has everything one might need to understand and practice mundane astrology. No prior knowledge of astrology is needed, as Greer guides the reader from the mundane interpretations of the planets and houses to the overlay of lunations and eclipses against the radical ingress chart. Greer thoughtfully includes a developed "cookbook"-style reference section, delineating the planets in houses and aspect, making this a great resource for the student. The proficient astrologer will also find plenty of novel insights and observations. Illuminating case studies and predictions illustrate the range and scope of the art.
