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 $n=6$, $t=-19.1$, $p \ll 0.001$, $df=5$.**

In this draft of a new interpretation of Germania Magna, the author presents his hypothesis that Germania Magna underwent a far more extensive landscape transformation in geologically recent times than previously assumed. This was presumably caused by post-glacial isostatic rebound during the Holocene, or by a possible reactivation of the Caledonian Deformation Front (CDF) during a late phase of the Alpine orogeny, along with the associated tectonic activity in the upper crust (see following section). There is also the consideration whether a cosmic impact event could have been the cause of such a reactivation of the CDF. The conditions that would be expected in order to sufficiently substantiate the process described below would probably also involve previously misattributed or incorrectly dated major fault events. These could have repeatedly triggered stronger earthquakes in Central Europe over several centuries and may even have been recorded in written sources from the later Middle Ages.[1]

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.

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 ≈28 km per Ptolemaic degree of longitude — remains unchanged. The statistically irrefutable −93.1 km eastward displacement of the Elster Cluster is the empirical core result.

Note: The geophysical evidence analysis below remains valid for v6. Section 4.2 uses an 8-point subset; the v6 main paper (tab. cesky_zones) expands this to n = 14 with p ≈ 3.4 × 10⁻⁵. The kinematic terminology (Section 8) reflects v5; v6 additions (K4 anchor, G7 biaxial extrusion) are documented in the main v6 paper only.

## 1. Synthesis of Evidence Chains: The Necessity of an Integrated View

The statistically secured findings of the preceding residual analysis – a highly significant eastward offset of the Elster-Lusatia Cluster of $\overline{\Delta}_\lambda \approx -93{.}1$ km ($t = -13{.}7$, $p < 0{.}001$) and the geochemical convergence of the cartometric identification *Budorigum* = Doberlug-Kirchhain with the local anthracite stress metamorphism anomaly – demand a geophysical explanation that goes beyond a purely statistical coordinate analysis. The four key publications under consideration (Nielsen et al., 2007; Arfai et al., 2018; Götze et al., 2023/2024; Weninger et al., 2008), together with Kužvart (1992) and Geersen et al. (2024), provide methodologically heterogeneous but independently derived building blocks that are systematically evaluated below and synthesised with the Mildner model. Particular attention is devoted to the Mercator map cited by Mildner, which shows a landmass named *Albionis Pars* in the *Oceanus Germanicus*, and to the hypothesis that a triggered tsunami may have contributed to an additional northward migration of the coastline through sediment deposition along the North German coast.

Sven Mildner contends that the dramatic geodynamic and climatic rupture of 536 AD likely involved a reactivation of the ancient Caledonian Deformation Front (CDF) and the Trans-European Suture Zone (TESZ). He argues that large-scale inversion tectonics, fueled by Alpine compressive forces, reshaped Germania Magna during this period. With the Lausitz Block anchoring these stresses, neighboring massifs like the Harz and Thuringian Forest underwent significant rotation and deformation. The consequences were environmental and societal collapse: catastrophic floods, firestorms, and the formation of the 'Event-Dark-Earth' (ED-E) layer, alongside a major regression of the North Sea. This transformation explains why the ancient, compact shape of Germania Magna vanished, leading to the abrupt end of its settlement history.

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
