This is the first English translation of "Astronomia Teutsch Astronomei", published in 1545 in Frankfurt am Main. The original work was one of the earliest astrological textbooks in the vernacular, predating William Lilly's famous English primer Christian Astrology by over a decade. With this translation, Peter Stockinger offers the English reader an exciting insight into the working methods of a 16th century astrologer living on the cusp of the Late Medieval and Early Modern periods. The book contains a detailed introduction by the translator, providing valuable background information and historical context, and is comprehensively annotated throughout.
