Medieval astrology refers to the astrological tradition that flourished between the 8th and 15th centuries CE, shaped by the translation and expansion of earlier Greek and Persian sources by Arabic-speaking scholars in the Islamic Golden Age. Centered in intellectual hubs such as Baghdad, this tradition absorbed Hellenistic, Persian and Indian influences, preserving and developing them through advanced astronomical models and astrological techniques.
Through a vast network of translators - most notably in Spain and Sicily - this body of knowledge entered Latin Europe, where it profoundly influenced universities, courts, and medical practice. Medieval astrologers refined essential and accidental dignities, expanded predictivemethods, codified electional and horoary astrology and integrated astrology into medical theory through decumbiture charts and humoral correspondences. This period represents a bridge between the Hellenistic foundations and the later Renaissance, maintaining a highly technical, mathematically grounded practice that was both schoarly and practical.
