After more than four years of work, this premier audio course is finally nearing completion. Based on Robert Schmidt's long involvement with the original sources, this course is much more than a simple introduction. In it you will find all the core concepts and techniques of the original system of Hellenistic astrological practice, which we call the The System of Hermes, organized into a coherent and self-contained system. At the present time, it is the only way available of gaining a comprehensive overview of the practice of Hellenistic astrology.
