Comparing Connectivity Patterns in Prehistoric Germany by Means of Network Analysis, Artefact and Site Distribution and a Reassessment of Human Mobility ( 87 Sr/ 86 Sr)
Open accessAbstract
Recent advances in the natural sciences, bioarchaeology and spatial analytical techniques have significantly improved our ability to reconstruct prehistoric human connectivity. However, traditional mapping approaches can often fail to integrate isotopic evidence with landscape modeling and artifact distribution comprehensively. This study addresses this gap by combining Least-Cost Path (LCP) analysis, spatial distribution of key archaeological artifacts (jade axes and hilted swords), and 87 Sr/ 86 Sr isotopic data from previous research to investigate movement corridors in the Late Neolithic (ca. 3,800–2,800 BCE) and Bronze Age (ca. 2,300/2,200–800 BCE) landscapes of central and southern Germany. Our objective is to model how prehistoric populations navigated and exploited natural landscape features for mobility and trade, assessing how these corridors influenced the spatial distribution of important trade commodities. By integrating isotopic data with modeled movement corridors, our study confirms through independent isotopic and spatial evidence, that mobility networks intensified and stabilized during the Bronze Age. This approach highlights a methodological advance rather than reiterating a well-known trend, as the broader variability of 87 Sr/ 86 Sr ratios directly corresponds with the establishment of sustained long-distance connections.

TL;DR
This study combines Least-Cost Path modeling, artifact distributions (Alpine jade axes and hilted swords), and published 87Sr/86Sr data to compare Neolithic and Bronze Age connectivity in central and southern Germany. It finds Bronze Age sites and hilted swords more tightly associated with low-cost corridors, while jade axes and Neolithic settlement show weaker or more dispersed corridor coupling, with isotopic data suggesting subtle increases in Bronze Age mobility.
Key findings
- Rhohat/LCP results: Neolithic sites show a slight but consistent increase in spatial intensity near modeled movement corridors (within ca. 0–10 km); Bronze Age sites show a stronger concentration in the lowest LCP costs and a sharper decline with increasing cost; hilted swords mirror the Bronze Age site trend, while jade axes show little to no enhancement in the lowest cost range and a comparatively flat curve across low-moderate costs.
- Strontium isotope patterns: Neolithic sites have a wider range of median 87Sr/86Sr values across sites but narrow intra-site distributions; Bronze Age sites have more stable site medians/narrower IQRs but a wider overall range and modestly greater intra-site variability, including more frequent outliers.
- An exploratory test found a negative relationship between LCP-derived corridor density and intra-site standard deviation of 87Sr/86Sr, with higher variability in low-accessibility areas and reduced variability in high-corridor-density areas.
- Datasets analyzed include 414 jade axe datapoints, 389 hilted sword finds, and 56 sites with 87Sr/86Sr data (34 Bronze Age, 22 Neolithic).
Methods
- The study area is present-day Germany. It integrates Least-Cost Path analysis, spatial distributions of Alpine jade axes and Bronze Age hilted swords, and published human 87Sr/86Sr data from the Big Interdisciplinary Archaeological Database (BIAD).
- LCP modeling used a modified “From Everywhere to Everywhere” approach with Circuit Theory concepts, implemented in GRASS GIS via R; a ∼300 m resolution DEM aggregated from SRTM-90 was used, and resulting paths were combined into a kernel density surface.
- Statistical testing used rhohat in spatstat to model point intensity relative to distance from high-use corridors or LCP cost; a separate network model used v.net.models with a 100 m DEM, and Neolithic clustering was reduced using KDE with σ = 3,000 m.
Limitations
- The paper states that LCP results depend on input surface parameterization; different friction models could shift corridor geometry; rhohat confidence envelopes widen where data are sparse; 87Sr/86Sr comparability rests on consistent baseline calibration and diagenesis screening; spatial equifinality remains a concern; modeled accessibility is a proxy, not a direct record of route use; and sample sizes are small in key categories.
- The text also makes evident that jade axes and hilted swords are separated by a chronological gap of over a millennium, site types were not differentiated in the LCP analysis, modern anthropogenic changes have modified the archaeological landscape and introduced preservation/visibility bias, and archaeological data are incomplete due to undiscovered and lost sites.

The Introduction says southern Scandinavia became more closely linked to European metal-trade networks, and ‘Comparing 3rd and 2nd millennia mobility’ links a change in mobility to long-distance trade.

Opposite descriptions of Bronze Age sites' corridor proximity
MajorOne results passage says Bronze Age sites are generally farther from high-mobility areas, while a later passage says they are more strongly concentrated in the lowest-cost, high-mobility terrain than Neolithic sites. These descriptions support opposite interpretations of the Bronze Age site pattern.
“In contrast, Bronze Age sites are more dispersed and generally located further from high-mobility areas.”
“Bronze Age sites display an even stronger concentration within the very lowest LCP costs, with intensity dropping sharply once costs increase (Figure 3A).”
Hilted-sword study dates do not overlap
MinorThe introduction dates the hilted swords modeled in the study to 2,200-1,600 cal BCE, whereas the materials section says the overall range of the hilted swords included is roughly 1,350-750 cal BC. The two stated ranges do not overlap.
“This study examines long-distance mobility and connectivity in Neolithic and Bronze Age Central Europe by modelling the movement of two object groups with widespread distributions: Alpine jade axes (c.5,300-3,700 cal BCE) and hilted swords (c.2,200-1,600 cal BCE).”
“The overall temporal range of the hilted swords included spans from roughly 1,350 to 750 cal BC, covering the Late Bronze Age's primary phases of socio-political change”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
