The historical geography of *Germania Magna* remains one of the most challenging fields in classical studies and geodetic research. The currently paradigmatically influential reference model — the statistical-geodetic rectification of the TU Berlin group (Karlsen et al., 2011) — explains deviations between Ptolemaic coordinates and modern topography primarily as measurement errors of ancient instruments or as transmission artefacts.

The present model is based on a fundamentally opposing assumption. The primary explanatory principle is the recognition that the northern reference coastline of the *Oceanus Germanicus* lay approximately 120 km further south in antiquity. Medieval cartographers projected Ptolemy's coordinates onto a landscape already altered by major 6th-century geodynamic processes. This produced a systematic northward stretching of the map image and a corresponding eastward displacement of eastern coordinates.

The cartometric foundation — a strictly affine transformation anchored on the invariant Rhine–Elbe baseline with a global scaling factor of $\approx 28\text{km}$ per Ptolemaic degree of longitude — remains unchanged. **Version 7 updates the core statistical result to an extended Elster Cluster of $n=6$, $t=-19.1$, $p \ll 0.001$, $df=5$.**

*This article presents an interdisciplinary working hypothesis integrating cartometry, geodynamics, sedimentology, and historical sources. It proposes a geodynamic and climatic rupture in the 6th century AD and formulates concrete, falsifiable predictions. The model challenges aspects of the current mainstream interpretation and is intended to stimulate further empirical testing. It does not claim to be a definitive reconstruction. The Saale-Unstrut Fragment Impact, the postulated third event at Vogelsberg/Frankfurt, and the unified Abnobae block identification remain hypotheses not confirmed by current peer-reviewed literature. The model has not been evaluated by peer review.*

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
