Scientifically important map of the region east of Paris to Venice, Vienna, Bresslau, Dantzig and Straslund, by Tobias Mayer.

During the mid-18th Century, Tobias Mayer was hired by the Homann firm to develope methods of map-projection. Between 1747 and 1754, at least 31 maps which bear his name. His sources for this map of Germany published by the Homann firm in I 753, three years after he had completed it, were laboriously-checked latitude determinations, large-scale maps of small areas, and the Antoninian, Augustan and Hierosolymitanian itineraries.

Of some 200 places shown on this map, only 33 were fixed by astronomical determinations of latitude. Nevertheless, it was of particular significance in being the prototype of the maps which were soon to be based upon much more accurate astronomical observations and trigonometrical measurements.

The map has been the subject matter of a number of modern scholarly works, including and article devoted entirely to the map, Hintergrunde und Analysen zu Tobias Mayers 'Kritischer Karte von Deutschland' [=Background and analysis of Tobias Mayer's 'Critical map of Germany'] by Peter H. Meurer, published in Cartographica Helvetica: Fachzeitschrift fur Kartengeschichte, July 1995.
