Synastry is the art of comparing two birth charts to determine relationship potential. It is often seen as a modern practice, but it has actually existed for about 2000 years. Yet while traditional astrology has gained considerable interest recently, traditional synastry has been overlooked, largely due to the lack of surviving ancient texts on the subject. In this lecture, I’ll share my years of research to reconstruct the original system of relationship astrology, drawing from the scattered references to synastry in Hellenistic and medieval sources. Come along to learn some easy and effective traditional synastry techniques and see them applied in example charts.
