Lithological maps visualizing the achievements of geological sciences in the first half of the 19th century

The paper discusses selected maps of rock strata which exemplify the evolution stages of presentation methods of cartographic data concerning the geological structure of selected countries (France, Great Britain and Germany) which in the first half of the nineteenth century constituted the leaders of the field. The results of geologists’ work are used to present the content of maps, provide explanations and showcase the methods and techniques chosen by the maps’ creators. The analysed maps are accompanied by geological writings which contain descriptions of the chronological order within rock formations and strata defined on the basis of fossils, methods of recreating the geological history of individual regions, and attempts of compiling the acquired knowledge and using it to describe larger areas. The author discusses also two maps of Europe published in the mid-nineteenth century, which are the result of cooperation and research achievements of geologists from different countries.
