Bernhard Varenius? books influenced the history of science in such a way that Isaac Newton, Alexander von Humboldt and Tsar Peter the Great all referred to him. Varenius wrote the first comprehensive description of Japan (Descriptio regni Japoniae, 1649) from a European perspective, exclusively based on a diversity of sources. But the impact of his Geographia generalis (1650) explains his ranking among the founding fathers of geography as a science. He called ?general? geography a branch of (applied) mathematics which does not deal with regional specifics. The contributions in this book focus on his multi-faceted work, the influence of his books and the tragically short life of this young polymath from Germany who benefited from the intellectually stimulating milieu of Leiden and Amsterdam.Contributors include: Horst Walter Blanke, Reinhard D?chting, Klaus Lehmann, Robert Mayhew, Sandra Rebok, Folker Reichert, Frank Richter, Margret Schuchard, Denis J.B.
