Dr Martin Gansten has studied and practised traditional astrology for more than thirty years and is the author of Primary Directions: Astrology’s Old Master Technique (2009), and Annual Predictive Techniques of the Greek, Arabic and Indian Astrologers. He has taught these important but often misunderstood methods of prediction to students worldwide in workshops and online. Much of his academic research concerns the history of astrology, and he has taken a particular interest in the transmission of Perso-Arabic (Tājika) astrological teachings to India, culminating in his translation of the voluminous Sanskrit work The Jewel of Annual Astrology (2020).
