The scientific study of the historical geography of Central Europe, particularly the so-called Germania Magna, has traditionally been governed by an interdisciplinary paradigm that primarily relies on archaeological findings, philological text analyses, and a gradualist, geological basic assumption. In recent times, the research work of Sven Mildner (https://www.germania-magna.de), which combines a multidisciplinary, computer-assisted distortion analysis of the medieval cartography of Donnus Nicolaus Germanus – based on Claudius Ptolemy – with neocatastrophist, geodynamic models, has triggered an unorthodox re-evaluation of these established constants.¹ The present research report synthesizes the far-reaching implications arising from this approach, situates them within the philosophy of science, and focuses particularly on the regional geological perspective of the Saxon-Bohemian area.

The central thesis of the present research discussion postulates that the transmitted Ptolemaic maps are not erroneous depictions of a static ancient world, but rather precise and accurate representations of a geography that existed prior to a massive geodynamic upheaval.¹ This assumption necessitates a radical shift in perspective: The topography of Central Europe was, in historically tangible times – specifically during the Late Antiquity and the Migration Period – subjected to drastic, cataclysmic changes triggered by cosmogenic impact events and the resulting tectonic reactivations.¹ This approach requires a fundamental re-examination of the causalities behind the loss of ancient geographical knowledge, the collapse of Late Antique power structures, the apparent discrepancy in ancient place coordinates, and the physical plausibility of impact chronologies in the Bohemian Massif.³
