FIRST EDITION of an "exhaustive sourcebook of astrological writings". Eschuid (John Ashenden) correlated celestial influence and terrestial events, and explicated astrological methods of prediction. One of his earlier predictions had coincided with the plague in 1348, and he treats the disease here, among other topics, making the Summa astrologiae "one of the first contemporary discussions of the Plague" (Stillwell). He mentions a powder used as treatment which was still considered efficacious for fever a century later. The world map derives inverted from one which first appeared in a 1483 edition of Macrobius. Nordenskiold considered the diagram of the relationship between the zodiacal signs and geographical locations also to be a map (Nordenskiold 3, 958). A FRESH, LARGE COPY.
