Leonhard Thurneisser zum Thurn (Basel 1531-1596 Cologne)
1575, Germany, Berlin
Leonhard Thurneisser, one of the most enigmatic figures of the 16th century, ran his own printing press since 1574. He published the Astrolabe at hand as a supplement to his famous Archidoxa. It contains the plates of Mercury, Venus, Mars, Jupiter and Saturn. The revolving cut out discs showing the constellations and other astrological features helped to determine the course of planets and their influences without calculation. Very rare.
