Very scarce regional map of Poland and Lithuania, showing the region bounded by the Narew River, Oletzko, Lotzen, Rein and Sensberg, and including Kolno, Biala, Johannisburg, Novigrod, Lomza, Ostrolonka, Rossen, Ortelsburg, Chorzellen, and Willenberg. This region was then part of the Prussian Empire. Shows rivers, roads, towns, castles, forests, lakes and a host of other details. Quite possibly the most detailed map of this region to appear in an 18th Century Atlas. From Von Reilly's exceedingly scarce Grosser Deutscher Atlas. Von Reilley & Schaembl led a revival of map making in Vienna in the late 18th Century which included this and several other sought after works.
