The environmental impact of cultural change: palynological and quantitative land cover reconstructions for the last two millennia in northern Poland

This paper presents the first quantitative past land cover reconstructions for northern Poland using the Landscape Reconstruction Algorithm (LRA), interpreted alongside traditional percentage pollen data and historical sources. These data are used to evaluate the impact of cultural change on past vegetation and land-use in northern Poland during the last 2000 years. Vegetation change and land-use are apparent corresponding to the late Roman Iron Age (1st to 3rd centuries), Migration Period (4th–7th centuries), early Medieval (8th to early-13th centuries) and late medieval (early-13th to mid-15th centuries). The Roman Iron Age is characterised by significant land cover estimates for meadowland, likely part of a broad spectrum agricultural strategy. Widespread depopulation and woodland regrowth characterise the Migration Period, followed by the progressive clearance of woodland from the 7th/8th centuries corresponding to Slavic colonisation. Polish control of the region from the mid-10th century is accompanied by intensification in agricultural land-use. However, archaeological evidence for increasing settlement instability during the 11th/12th centuries is not obviously apparent in the palynological data. This likely reflects the sporadic nature and uneven impact of conflict, but also the difficulty in resolving short-term events in the palynological record. Significant woodland clearance occurred prior to the crusades, with the consequence that there is no clearly identifiable horizon of significant landscape change associated with the arrival of the Teutonic Order. However, large tracts of woodland survived in sparsely populated frontier zones and in areas with poor agricultural soils, managed as part of an extensive provisioning network covering the Teutonic Order's state

The cultural roles of perforated fish vertebrae in prehistoric and historic Europe

This paper provides a new synthesis of perforated fish vertebrae in prehistoric and historic Europe, with a particular focus on Poland, within the broader context of Central and Eastern Europe. The earliest examples of such artefacts in Europe date from the Upper Palaeolithic, but compared to other ‘beads’ manufactured from animal bone, perforated fish vertebrae are rare. This paper examines the diachronic trends in the range of species that have been chosen for such objects, as well as their depositional contexts. Despite the wide range of freshwater and marine species exploited by people, only the vertebrae of a few species—especially pike and catfish—were selected for use as beads. There is a general shift from their deposition in funerary contexts in prehistoric European societies to their association as low-status objects associated with Christian private devotion in the post-conversion period. However, this may not reflect continuity in the use of fish vertebrae, with a shift in their symbolism after the conversion to Christianity, given the substantial chronological gaps in the archaeological record. This synthesis nonetheless provides a solid foundation for contextualising future archaeological finds of such artefacts

Re-thinking the ‘Green Revolution’ in the Mediterranean world

From the seventh century AD, successive Islamic polities were established around the Mediterranean. Historians have linked these caliphates with the so-called ‘Islamic Green Revolution’—the introduction of new crops and agricultural practices that transformed the economies of regions under Muslim rule. Increasingly, archaeological studies have problematised this largely text-based model of agrarian innovation, yet much of this research remains regionally and methodologically siloed. Focusing on the Western Mediterranean, the authors offer a theoretically informed, integrated environmental archaeology approach through which to contextualise the ecological impact of the Arab-Berber conquests. Its future application will allow a fuller evaluation of the scale, range and significance of agricultural innovations during the ‘medieval millennium’

Evidence for the onset of mining activities during the 13th century in Poland using lead isotopes from lake sediment cores

Efforts to study how human activities have influenced the environment since the end of the Roman period to present day are lacking for North Central Europe. Here, we present new lead (Pb) isotope data determined from two sediment cores collected from ancient lakes spanning the last 1,500 years, located in the Kuyavian-Pomeranian Voivodeship, Poland. Study sites at Radzyń Chełmiński and Rywałd were used to differentiate Pb sources. Radzyń Chełmiński is located in the vicinity of a late Medieval Teutonic Order castle and town, while Rywałd is situated within a relatively pristine area until the 19th century when it became used for agricultural purpose. Core samples were analyzed for Pb concentration and isotopes (206Pb, 207Pb, 208Pb). Bayesian modelling was used to isolate the anthropogenic signal at each site over time. For both sites, Pb enrichment factors relative to titanium (Ti) and upper continental crust values range from 13 to 159. Lead isotopic ratios range from background, pre-anthropogenic local values (206Pb/207Pb =1.31±0.03‰, 208Pb/206Pb = 1.97±0.04‰) to anthropogenic values (SW Poland coal, ore, slag 206Pb/207Pb = 1.17±0.01‰, 208Pb/206Pb = 2.09±0.01‰). Modelled anthropogenic contribution varies greatly over time, ranging from 14 to 100%. At Radzyń Chełmiński, modeled anthropogenic Pb contribution and measured Pb concentration follow similar trends. However, at Rywałd, from around A.D.1000 to A.D. 1400 these profiles diverge significantly. Our new insights highlight different sources of Pb from the 12th century to present day: (1) short range agricultural activities from the town, and (2) long range mining activities. Additionally, prior to the 12th century, our data suggest continental anthropogenic activity possibly favored by a warmer climate

Feeding the crusades: archaeobotany, animal husbandry and livestock alimentation on the Baltic frontier

The integrated results of micromorphology, plant macrofossil, pollen, phytolith, and non-pollen palynomorph analyses represent an important study of two thirteenth-century Teutonic Order castles at Karksi (Livonia), and Elbląg (Prussia). The research examines deposits that formed during the period of active crusading. At Karksi, the investigation of a midden and of the organic-rich sediment beneath allows the diachronic use of this area to be understood. Freshwater aquatic indicators are consistent with the occurrence of shallow stagnant water, as also suggested by a waterlaid pond sediment identified in thin-section. Coprophilous spore taxa suggest the use of the pond as a watering hole. Plant macrofossils from the midden represent a range of habitats, mostly from wet/damp areas, as well as pastures and meadows, and also woodlands. Fragments of millet are embedded within herbivore dung in thin-section showing the use of this grain as fodder. At Elbląg, parasite ova may derive from animal feces as they also occur in the dung observed in thin-section, and a range of coprophilous fungal spore taxa were extracted. The results reveal information about the range of livestock that the Teutonic Knights kept, whereabouts within the castles the animals were stabled, and what fodder was used

Late-Medieval Horse Remains at Cesis Castle, Latvia, and the Teutonic Order's Equestrian Resources in Livonia

EXCAVATIONS AT the castle complex of Cēsis, Latvia, uncovered an unusual find of large quantities of horse bones, some of which were partially articulated, along with equestrian equipment. These were associated with a destroyed building at the edge of the southern outer bailey. The horses included large males, most probably stallions, and pathology on several of the recovered vertebrae suggests these individuals had been used for riding. The size of the horses was within the range for medieval war horses, and the associated tack also pointed to prestigious riding animals. Radiocarbon dating of the bones placed them firmly within the Teutonic Order's period of rule. We conclude here that these horses fulfilled a military role in the final decades of the Teutonic Order’s rule in Livonia in the late 15th/early 16th century and that the better-known equestrian culture of late-medieval Prussia was comparable in character, if not in scale, to that in Livonia
