Join our esteemed astrologers Shu Yap, Öner Döşer, Anthony Louis, and Joy Usher, in this panel discussion exploring the foundations, development, and distinct character of Medieval astrology. This moderated webinar brings together experienced teachers and professional astrologers from the Medieval Astrology Certificate to discuss what defines the Medieval tradition, how it differs from other astrological eras, and why it remains relevant for astrologers today.
Drawing from Persian, Arabic, and Latin Medieval lineages, the panel examines how astrology evolved between the 8th and 14th centuries through advances in mathematics, astronomy, and technology, as well as changing cultural and political contexts that shaped astrological practice. Discussion touches on the emergence of new techniques and tools, the role of astronomical knowledge, and the defining features of Medieval systems such as significators, planetary condition, almutens, hylegs, and time-lord methods.
This webinar is ideal for astrologers who want a clearer understanding of what Medieval astrology is, how it developed, and how it differs from other traditions. It is well suited for students actively studying Medieval astrology, practitioners curious about classical techniques, and those considering deeper training through the Medieval Astrology Certificate.
