The Western Sidereal Interpretation Workbook

Now Available for Pre-Order!

In An Introduction to Western Sidereal Astrology, Kenneth Bowser presented the basics of western sidereal astrology—the history and rationale, the stars, planets, signs, aspects and planet combinations. In The Western Sidereal Astrology Interpretation Workbook, he shows you how to apply this knowledge to the art of chart interpretation. In this step-by-step workbook, Ken will guide you through the interpretation of 25 horoscopes. When you have completed each chart, you will compare it to Ken’s interpretation at the back of the book. In this way, you will hone your skills and expand your ability to correctly read astrological symbolism.

A well-known astrologer with over 50 years of experience in chart interpretation, Ken will show you how to identify and synthesize the dominant themes in each horoscope. Two hours of private tutoring are included. Ken will critique your interpretation of the final chart, or personally guide you through your interpretation.​

  • How to incorporate in-mundo or mundane aspects into your interpretations. Mundane aspects, one of the most sophisticated tools in an astrologer’s toolbox, will allow you to see the hidden aspects that are missed when you look at a chart in only one dimension.


  • How to read a speculum. Derived from the Latin verb specere, “to look at or behold,” a speculum will allow you to see the positions of planets in two dimensions.​

  • How to incorporate stars into your interpretation

  • How to use a wider range of aspects for a more thorough evaluation of each horoscope


  • ​The importance of elevation and angularity in the horoscope


  • How to incorporate the nodes of the Moon into your interpretations
