It is obvious that the author spent a lot of time and effort in writing this book. It is about 245 pages long but the fonts are small so the book would be much thicker if it were printed in regular sized fonts. This book has two shortcomings listed below:
1. No information to create the Arabic Astrology Charts! So this is not the book for the beginners
2. Part III of the books from page 139 through page 224 is titled " Practical Illustrations". But only two out of five sample readings in it has some practical use, in my opinion. They are the interpretations for a prostitue and Watergate incident. I am skeptical when astrolgy tries to predict a country's or the world's events.
In short, there is a lot of theoretical information but VERY LITTLE PRACTICAL INFORMATION dealing with prediction. You'll need another book to go with this one.
Many 20th century astrological treatise ignore its history. Most of them, in fact. When I started reading Robert's book I became intrigued. Here was an approach to the world that was based on a scholar's research into the ancient sciences. So, I kept on reading. I discovered a world of wisdom and science I had believed was lost. It was a simple, yet technical approach. It was rigorous, yet accurate. It opened the door to astrological prediction. Most of all, it inspired me to dig and learn. It's a good prelude to Robert's online course.... . . If you want to dig and find answers, instead of glossing over the details with "feel good" language, Zoller's work is a wonderful place to begin.
