The art of predicting earthly events from the movements of stars and planets has always been a source of fascination. Medieval astrologers, though sometimes feared to be magicians in league with demons, were usually revered scholars whose ideas and practices were widely respected. Politics, medicine, weather forecasting, cosmology and alchemy were all influenced by astrological concepts. Astrology in Medieval Manuscripts explores the dazzling complexity of western medieval astrology and its place in society, as revealed by a wealth of illustrated manuscripts from the British Library's rich medieval collection.
