Notes: A very good copy of probably the most beautiful German geological books of the 18th century.A classic. it is the first geognostic description of the Harz Mountains and contains also important observations concerning the genesis of ore bodies. It is known that Goethe collaborated at the production of this 'handsome and well illustrated folio' (Adams). Trebra accompanied him on his well-known wanderings through the Harz Mountains as a friend and geological adviser, and the five beautiful text-engravings were designed during this tour by Georg Melchior Kraus, painter and engraver from Weimar (see...moreA very good copy of probably the most beautiful German geological books of the 18th century.A classic. it is the first geognostic description of the Harz Mountains and contains also important observations concerning the genesis of ore bodies. It is known that Goethe collaborated at the production of this 'handsome and well illustrated folio' (Adams). Trebra accompanied him on his well-known wanderings through the Harz Mountains as a friend and geological adviser, and the five beautiful text-engravings were designed during this tour by Georg Melchior Kraus, painter and engraver from Weimar (see G. Schmid, Goethe und die Naturwissenschaften). "It contains Trebra's observations and theories on the rich mineralization of the Harz Mountains in Germany, anticipating modern theories of ore body formation through metamorphism and mineral replacement. It is finely illustrated on the plates and vignettes that incorporate on one plate ground mica to give realistic `sparkles' to the rendering of a mineralized vein of ore." (C. Schuh's Bibliography of Mineralogy, in Mineralogical Record database).  HIDE
