This is a great manual on astrological geomancy. Most of the text is interpretive guidelines for each judge and witness combination as well as for each geomantic figure in each of the houses (either alone or with planets). The beginning section of the book explains how this approach to astrological geomancy works and outlines a few different example readings (on a nice range of topics - a 'when' question, several 'will...' questions, a general 'what are the highlights of the coming month' chart, etc). I will absolutely keep this on my shelf as a reference and use it for interpreting geomancy readings with astrology incorporated.
I do have a few issues with this book. The authors repeatedly refer to sign-based aspects as "mundane astrology" which is simply not accurate / not what 'mundane astrology' is. Additionally, the book reads as quite heteronormative, with many references to 'the opposite sex' and 'the man of the house' and things like this that will absolutely not be relevant to all readers. I would hope that if this book is ever republished these latter issues in particular would be rectified.
The authors provide a new system of horary, mundane astrology and geomancy based in Agrippa's system. They have created a variation and they explain it well in the first 34 pages. 6 examples follow and hundreds of pages with interpretations-guidelines. Concerning the geomantic figures and the houses I would advise the reader to read more classical books on those subjects. This system is for the geomancers who want to create a different house chart and interpret it for long time frame questions.
