Practices of Wealth Depositing in the 1st–9th Century AD Eastern Baltic

This PhD thesis discusses the practices of wealth depositing in the 1st–9th century AD eastern Baltic (Estonia, Latvia, Lithuania). Wealth deposits are one or more valued object/s that is/are hidden deliberately as an intended separate deposition in a selected place in a specific, distinguishable manner. Wealth depositing is regarded as an important cultural practice which relates to and derives from various past social phenomena and changes respectively in spatial and temporal terms. It is emphasised that wealth deposits should be analysed as a cohesive corpus of material, regardless of specific artefact types, functional groups, production material, environment of concealment, and most importantly without any predetermined interpretation categorisations. The dissertation presents different patterned practices of concealing valuables in the 1st–9th century AD eastern Baltic through a detailed contextual analysis of their main material characteristics: artefacts, their assemblages and appearance, environment of concealment, chronology and location in the cultural landscape. The study demonstrates how depositional practices change in time and space, and analyses relations between specific depositional practices and developments on a wider social scale. A comparative analysis of wealth deposits and important social changes in contemporary society based on overall archaeological material is presented. The key regional and cross-regional practices of wealth depositing in the 1st–9th century AD eastern Baltic are identified. Additionally, further comparisons are drawn between depositional practices in the eastern Baltic and other parts of the Baltic Sea region, especially Scandinavia. This thesis contributes to the discussions of concepts of value and depositional practices in a long-term and cross-regional perspective. A further aim is to look beyond the problematic ‘why?’-questions posed in the studies of wealth deposits, and move instead to more comprehensible questions of ‘how?’: how do depositional practices change in time and space, and how are these processes related to developments in a broader social context? The book contains a catalogue of all the 1st-9th century AD Eastern Baltic deposits analysed in the dissertation with descriptions of objects, environments of concealment, find circumstances, illustrations/photos and further references

Stone Age imitation of a slotted bone point from Pärnu River (south-western Estonia)

This is an in-depth study of a mimicked slotted point, carved from a cervid longbone, found in the lower reaches of the Pärnu River. The 3D digital model, created during this study, provides an interactive and innovative tool for studying the object in detail. The AMS dating places the artefact at the very beginning of human habitation in the present-day territory of Estonia. SEM-EDS, ATR-FT-IR and GC-FID/MS analyses demonstrate that this unique object was probably originally partially covered with a mixture of red ochre and some coniferous resin, possibly as hafting adhesive. As this is a detailed replica of a slotted point, it also demonstrates how people themselves saw slotted points in the Early Mesolithic, also raising the question of the purpose of this replica â was it an ordinary arrowhead or rather a ritual object

The impact of farming on prehistoric culinary practices throughout Northern Europe

To investigate changes in culinary practices associated with the arrival of farming, we analysed the organic residues of over 1,000 pottery vessels from hunter-gatherer-fisher and early agricultural sites across Northern Europe from the Lower Rhine Basin to the Northeastern Baltic. Here, pottery was widely used by hunter-gatherer-fishers prior to the introduction of domesticated animals and plants. Overall, there was surprising continuity in the way that hunter-gatherer-fishers and farmers used pottery. Both aquatic products and wild plants remained prevalent, a pattern repeated consistently across the study area. We argue that the rapid adaptation of farming communities to exploit coastal and lagoonal resources facilitated their northerly expansion, and in some cases, hunting, gathering, and fishing became the most dominant subsistence strategy. Nevertheless, dairy products frequently appear in pottery associated with the earliest farming groups often mixed with wild plants and fish. Interestingly, we also find compelling evidence of dairy products in hunter-gatherer-fisher Ertebølle pottery, which predates the arrival of domesticated animals. We propose that Ertebølle hunter-gatherer-fishers frequently acquired dairy products through exchange with adjacent farming communities prior to the transition. The continuity observed in pottery use across the transition to farming contrasts with the analysis of human remains which shows substantial demographic change through ancient DNA and, in some cases, a reduction in marine consumption through stable isotope analysis. We postulate that farmers acquired the knowledge and skills they needed to succeed from local hunter-gatherer-fishers but without substantial admixture

Data sharing practices and data availability upon request differ across scientific disciplines

Data sharing is one of the cornerstones of modern science that enables large-scale analyses and reproducibility. We evaluated data availability in research articles across nine disciplines in Nature and Science magazines and recorded corresponding authors' concerns, requests and reasons for declining data sharing. Although data sharing has improved in the last decade and particularly in recent years, data availability and willingness to share data still differ greatly among disciplines. We observed that statements of data availability upon (reasonable) request are inefficient and should not be allowed by journals. To improve data sharing at the time of manuscript acceptance, researchers should be better motivated to release their data with real benefits such as recognition, or bonus points in grant and job applications. We recommend that data management costs should be covered by funding agencies; publicly available research data ought to be included in the evaluation of applications; and surveillance of data sharing should be enforced by both academic publishers and funders. These cross-discipline survey data are available from the plutoF repository.Peer reviewe

The globular amphora culture in the Eastern Baltic : new discoveries

Until now, Šventoji in northwest Lithuania was considered the most northern site of the Neolithic Globular Amphora Culture (hereafter GAC; ca. 3400–2500 cal BC) in Europe. Recently, however, ceramics typologically resembling GAC ware were identified among the materials from the multi-period sites of Abora 1 and Iča in Latvia and further to the north from Tamula in southeast Estonia. Here we present the multi-disciplinary analyses of these ceramics, including their morphology, function and chronology, to ascertain whether they could represent sporadic migrations of GAC groups into the region or exchange and increasing social contacts with the indigenous hunter-gatherers during the period from ca. 3000–2600 cal BC. Overall, our results align with previous studies showing that GAC groups in the Eastern Baltic possibly reorientated their economy from animal husbandry towards fishing, as recently evidenced by the composition of zooarchaeological assemblages, and the organic residue analysis of ceramic vessels, which markedly differ from the GAC communities of Central Europe. Indeed, in several coastal and southern regions of Lithuania, it would appear that some GAC migrants replaced the indigenous Subneolithic forager groups, whilst in other areas, they had little to no impact on the local cultural and economic development

Multi-isotopic analysis of zooarchaeological material from Estonia (ca. 200–1800 CE): Variation among food webs and geographical regions

To better comprehend the dietary practices of past populations in the Eastern Baltic region we have created temporally and geographically restricted baselines for the time period of 200–1800 CE. In this multi-isotopic analysis, we report new δ13C, δ15N and δ34S values for 251 faunal bone collagen samples from various archaeological contexts in Estonia representing the most comprehensive set of Iron Age, Medieval and Early Modern Period faunal stable isotope values to date. The results map out the local carbon and nitrogen baselines and define isotopic ranges of local terrestrial, avian and aquatic fauna. We also demonstrate the potential application of sulfur stable isotope analysis in archaeological research. The results demonstrate a clear distinction between δ13C and δ34S values of marine and terrestrial species, however, freshwater fish display notable overlaps with both marine and terrestrial ranges for both δ13C and δ34S values. Herbivores show variation in δ34S values when grouped by region, explained by differences in the local biotopes. This study is the first attempt to connect the Eastern Baltic isotopic baselines and provides more detailed temporal and geographical references to study the local ecologies and interpret the human data

Multi-method Analysis of Avian Eggs as Grave Goods: Revealing Symbolism in Conversion Period Burials at Kukruse, NE Estonia

Eggshells are unusual finds in the Iron Age of eastern Europe (500 BC–1200 AD) deserving extra attention in terms of analysis as well as interpretation. This paper discusses two rare eggshell finds, discovered in female burials at the conversion period (12th–13th century AD) cemetery at Kukruse, NE Estonia. Our multianalytical study combining FT-IR, SEM(-EDS), microscopy and ZooMS provides an overview of methods applicable for identifying egg species, their predepositional history and curation. Based on the analytical results and the comparative analysis of the content and context of these two burials, we argue that different aims and connotations lay behind depositing eggs as burial goods, allowing well-supported interpretations of both pagan and Christian religious worldviews simultaneously

Parallel worlds and mixed economies : multi-proxy analysis reveals complex subsistence systems at the dawn of early farming in the northeast Baltic

The transition from foraging to farming was a key turning point in ancient socio-economies. Yet, the complexities and regional variations of this transformation are still poorly understood. This multi-proxy study provides a new understanding of the introduction and spread of early farming, challenging the notions of hierarchical economies. The most extensive biological and biomolecular dietary overview, combining zooarchaeological, archaeobotanical, dietary stable isotope and pottery lipid residue analyses is presented, to unravel the nature and extent of early farming in the 3rd millennium cal BCE in the northeast Baltic. Farming was introduced by incoming Corded Ware cultural groups (CWC), but some dietary segregation existed within these communities, with some having more access to domesticates, others incorporating more wild resources into their diet. The CWC groups coexisted in parallel with local hunter–fisher–gatherers (HFG) without any indication of the adoption of domesticates. There was no transition from foraging to farming in the 3rd millennium cal BCE in the NE Baltic. Instead, we see a complex system of parallel worlds with local HFGs continuing forager lifeways, and incoming farmers practising mixed economies, with the continuation of these subsistence strategies for at least a millennium after the first encounter with domesticated animals
