Deák Antal András: A Duna fölfedezése
Tartalom - III.A DANUBIUS PANNONICO-MYSICUS, 1726
T II E DISCOVERY OF THE DANUBE during the years of the surveys. His and Marsigli's accurate surveys 12 1 provided the basis for drawing the Danube river and the countries through which it flowed with an authenticity beyond their original function. These maps became the basis for other important maps such as the first commercial and postal maps of Hungary, and even the Danubian and Hungarian maps of the Danubius Pannonico-Mysicus, which were the models for the maps of Hungary made in Western Europe for nearly a century as well as the "large" map of Hungary depicting the Hungarian Kingdom and the Transylvanian Principality published in 1709, which exceeded all former maps in accuracy. Müller definitely hinted at the same in his legend saying that he had drawn the settlements, the mountains, the forests, the distances between the lakes and the boundaries of the provinces and countries with great care and ended his sentence with: we borrowed all these faithfully and very accurately from extremely detailed manuscript maps. Because of the Turkish occupation it had previously not been possible to produce similar maps. Contemporaries also recognised the significance of Marsigli's and Müllers cartographic activitiesduring the demarcation of the frontier. An oil painting is preserved in the Marsigli Museum in Bologna which commemorates the cartographic work which followed the peace treaty of Karlovic. The leader of the Turkish commission is sitting on the ground in front of his tent confusedly gazing at the map laid out in front of him, while selfconfident Austrian imperial officers are standing by his sides. This is probably the first diplomatic scene in the world where a map is at the focus of a picture.

The courses and the bends in the rivers were checked by compasses and when they felt it necessary, the surveyors used their quadrant to determine their geographical position. 115
