Gans, David. Nechmad Vena’im [on astronomy, geography, as well as a rejection of astrology in Jewish tradition]

Latin introduction by Christian Hebenstreit, Professor of Hebrew in Leipzig, drawing attention to the keen influence the author received from the theories of the Danish astronomer Tycho Brahe, with whom Gans worked in Prague. Scientific co-operation between Jewish and non-Jewish savants was unique to the Rudolfine era. The MaHaRa”L of Prague himself (whom Gans was a disciple) is said to have been invited to the Hradschin Palace to meet with Emperor Rudolph II. See A. Neher, Jewish Thought and the Scientific Revolution of the Sixteenth Century: David Gans (1541-1613) and His Times (1986) pp. 58-91 and pp. 6, 20, 24.
