Samuel Reyher as practising mathematician: a successor of Mercator? On the problem of the relation between theology and natural sciences on the eve of the Enlightment. Reyher, a cosmographer, geographer, mathematician, universal scientist and universal mathematician? (Q2735061)

Reyher, who remained rather unknown until about 1965, was born near Gotha (Thuringia) in 1635 and studied in Leipzig and Leiden almost all university subjects, except medicine. He became professor of mathematics at Kiel. There appeared Reyher's main work ''Mathesis Mosaica'' in 1669, in later editions called ``Mathesis Biblica'', which was meant as a ``mathematical demonstration against all atheists'' and sold therefore very well. The article focuses on Reyher's versatility, his philological capabilities, and his methods, less on his positive impact on science or mathematics. However, the notion of ``Stadtgeographie'' (town geography) can possibly be linked to Reyher's books mentioned before.NEWLINENEWLINEFor the entire collection see [Zbl 0964.00032].
