"The art of predicting earthly events from the movements of the stars and planets exerts an enduring fascination. Medieval astrologers were sometimes feared as magicians, said to be in league with demons, but usually they were revered scholars whose ideas and practices permeated many layers of society and individual lives. Agriculture, politics, medicine, weather forecasting, cosmology and alchemy were all influenced by astrological concepts, calculations and iconography." "Astrology in Medieval Manuscripts describes the complexity of western medieval astrology and its place in society, as revealed by a wealth of illustrated manuscripts and historical background."--BOOK JACKET.
