• Beef, butter, and broth: cooking in 16th-century Sweden

  2025. Emma Maltin (et al.). Archaeological and Anthropological Sciences 17 (2)

  Article

  We present the organic residue analysis of sherds of 50 cooking vessels from the 16th-century town of Nya Lödöse, Sweden. We confirm previous analyses showing that lipids are absorbed by glazed ceramic. By analyses of biomarkers and compound-specific stable carbon isotope analyses of fatty acids, we show that pipkins and pans were used for cooking ruminant carcass products, dairy, and plant foods. The dominance of ruminant fat and dairy reflects the importance of oxen and butter in the local food culture. The vessels included in the present study show some degree of specialized function. Pipkins had more traces of ruminant carcass fats compared to pans. Medium and large-sized pipkins contained a combination of animal fats and plant traces, possibly representing the preparation of stews. In contrast, the smallest pipkins showed no traces of plant foods and might have been used to melt animal fat. Pans had more traces of butter and had been exposed to higher temperatures, indicating frying. Flat pans were, to a higher degree, used for the frying of fish than the deep ones, but fish seem nonetheless to be underrepresented in the lipid residue data. According to zooarchaeological and historical data, fish, pork, and poultry were important parts of the diet, but as traces of these foodstuffs are scarce in the organic residue analysis, it may be inferred that they were prepared differently—boiled in metal cauldrons, roasted on metal spits over the open fire, or consumed in their dried, salted, or smoked state without further preparation.

• Why Pottery? A Finnish View on the Adoption and Use of Early Pottery

  2024. Petro Pesonen (et al.). Early Pottery Technologies among Foragers in Global Perspective, 13-36

  Chapter

  Why was pottery adopted by Late Mesolithic societies in the northwestern parts of Eurasia? This paper investigates new insights and results from recent studies in Finland. In this region, pottery was initially adopted by hunter-gatherer-fisher communities ca. 5300–5100 BCE, which in local terminology marks the beginning of the Neolithic era, even though other aspects of the Neolithic (e.g., agriculture, animal husbandry) were not yet adopted. Though the introduction of pottery in a non-agricultural sphere has recently been the subject of intense discussion, the motives behind mobile hunter-gatherer-fisher communities adopting pottery remain unsubstantiated. The earliest pottery has commonly been thought to have had a highly specialized function, in particular in the processing of aquatic food resources. To test whether the function of the earliest pottery in Finland was linked to subsistence, or diversified beyond economic necessities, we compared the results of pottery lipid analyses with animal osteological records across inland and coastal sites in the Late Mesolithic (ca. 6200–5300 BCE) and Early Neolithic (ca. 5300–3900 BCE). The zooarchaeological evidence, which remained consistent throughout the period studied, shows a versatile use of animal resources. It did not, however, converge with the inferred pottery function. Organic residues analyzed from ceramic cooking ware point to a non-specialized use of pottery that does not track the overall diet or subsistence among Finnish Stone Age cultures. We hence argue that the uptake of pottery in Finland was not a result of change in economies, but that pottery—a new and useful cooking and storage utensil at the time—was taken into household use in various environments and subsistence strategies. The reason why pottery was not in use in some areas and periods of time may thus be sought elsewhere, e.g., among communities with distinct sociocultural and even ethnic backgrounds.

• Disaster, survival and recovery: the resettlement of Tanegashima Island following the Kikai-Akahoya 'super-eruption', 7.3ka cal BP

  2023. Junzo Uchiyama (et al.). Antiquity 97 (393), 557-575

  Article

  Archaeologists have traditionally framed the impacts of natural disasters in terms of societal collapse versus cultural resilience. The 7.3ka cal BP Kikai-Akahoya (K-Ah) ‘super-eruption’ in south-western Japan was among the largest volcanic events of the Holocene. Here, the authors deploy a multi-proxy approach to examine how K-Ah devastated Tanegashima Island. While local Jōmon populations were annihilated, surrounding communities survived and eventually returned, adjusting their subsistence base to survive in the damaged environment. The article concludes that neither ‘collapse’ nor ‘resilience’ fully capture the complex dynamics of this process and that more research is needed to understand how disasters shape cultural trajectories.

• Source-sink dynamics drove punctuated adoption of early pottery in Arctic Europe under diverging socioecological conditions

  2023. Erlend Kirkeng Jørgensen (et al.). Quaternary Science Reviews 299

  Article

  What drives the adoption of pottery amongst prehistoric foragers in high-latitude environments? Following the long-running interests of archaeology in explaining the origin and dispersal of new technologies, recent years have seen growing efforts to understand what drove the emergence and expansion of early hunter-gatherer pottery use across northern Eurasia. However, many regional dimensions to this continental-scale phenomenon remain poorly understood. Initial pottery adoption has often been explained as a generic cultural response to warming climates and the growing diversity of food resources, yet resolving challenges of food security during seasonal shortfalls or general climatic downturns may have provided alternative motivations. It is also becoming clear that many regions experienced more complex patterns of pottery adoption and that many resist simplistic monocausal interpretations. In this paper we deploy a Human Ecodynamics framework to examine what drove the punctuated adoption of two early pottery traditions into Arctic Maritime Europe, which were separated by a multi-millennial ceramic hiatus – Early Northern Comb Ware (ENCW) and Asbestos Tempered Ware (ATW). Our multi-proxy approach involves the revision of pottery chronologies to clarify the timing and ecological context for each dispersal, combined with analysis of technological and functional dimensions of the ceramic traditions to understand the contrasting social organization of these technologies. Our results confirm that ENCW expanded at a time of increased locational investment and ecological abundance in the region, while ATW spread in a series of smaller and more intermittent waves in the context of a major ecological downturn and alongside a return to a high-mobility lifestyle. Finally, we use the concept of “source-sink dynamics” to suggest that both dispersals were driven by the same underlying process. This involved major climatic fluctuations triggering small-scale population transfers from lake and riverine settings of western Russia, Finland and the Eastern Baltic region via interior areas and through to the Arctic Norwegian coastline, a persistent process that is also well-documented in later historical periods. Our results highlight the crucial importance of bridging-scale case studies as these have the “unsettling” potential to highlight deeper problems of equifinality. In this case, they reveal that two broadly similar material traditions spread into the same regions, albeit in the context of strikingly different environmental and behavioural conditions.

• The harpoon stands yonder: Shape variation and functional constraints in Mesolithic complex weapon points from the circum-Baltic Sea area

  2023. Fredrik Lundström (et al.). Journal of Archaeological Science 51

  Article

  Mesolithic harpoons are structurally complex weapon points and significant sources of archaeological information. Nonetheless, separating different types of information inherent in harpoon point shapes (e.g., aspects relating to mechanical performance, personal or group craft variation and chronology) using descriptive approaches is difficult. In this study, we employed an exploratory geometric morphometric approach to the analysis of 28 Mesolithic harpoon points, and 144 undated harpoon points from the circum-Baltic Sea area in order to retrieve both functional and spatiotemporal information. By analyzing harpoon structure statistically through (i.) a shape proxy (harpoon silhouette) and (ii.) harpoon sub-structures (barbs), we have been able to reveal information related to both variation in shape convention and functional constraints. Barb shape results revealed statistically significant chronological and geographical groupings with spatiotemporal barb-shape trajectories made visible and objective evaluation of how barb-shape conventions impacted functional variation. In addition, harpoon silhouette shape distributions were shown to have potential as sources for robust artifact classifications in relation to functional constraints and raw-material engagement. These results suggest that morphometric approaches similar to the ones we have employed offer promising ways of addressing specific archaeological questions in the context of harpoon point shapes and, more generally, other complex weapon point forms.

• Cultural adaptations and island ecology: Insights into changing patterns of pottery use in the Susuya, Okhotsk and Satsumon phases of the Kafukai sites, Rebun Island, Japan

  2022. Ari Junno (et al.). Quaternary International 623, 19-34

  Article

  Island chains provide access to terrestrial, coastal and offshore marine resources, attracting peoples and cultures and serving as conduits for migrations and long-distance exchange networks. Situated between Hokkaido and Sakhalin, Rebun Island connected the prehistoric cultures of northeast Asia in a major “marine highway”. Rebun was repeatedly settled by distinct cultures who originated in different geographic locations and left an imprint on the local ecology. To better understand how these cultures adapted to the local island ecosystems, lipid residues from household cooking containers were investigated across a 1000-year period at the Kafukai river mouth on Eastern Rebun, where a prominent Late Holocene settlement cluster is located. Our study suggests periodical shifts in pottery function, with the Susuya focussed on the processing of intermediate trophic-level aquatic resources, and Early Okhotsk specializing towards isotopically enriched marine products. In the Middle Okhotsk phase, both marine and terrestrial animal, and plant resources were exploited. These findings elucidate changing patterns of household consumption and the range of resources processed between cultural periods. We conclude that pottery lipid analysis can play an important role in island archaeology, clarifying shifting relationships between communities, exploitation of resources and the responses of new cultural traditions to new insular ecological niches.

• Early pottery use across the Baltic – A comparative lipid residue study on Ertebølle and Narva ceramics from coastal hunter-gatherer sites in southern Scandinavia, northern Germany and Estonia

  2019. Vasiliki Papakosta, Ester Oras, Sven Isaksson. Journal of Archaeological Science 24, 142-151

  Article

  The Late Mesolithic Ertebølle and Narva cultures (6th – 5th/4th millennium BC) in the southwest and eastern Baltic, respectively, shared similar vessel types, namely pointed-based pots and oval bowls. As a consequence, this phenomenon raised questions about inter-cultural connections across the Baltic and possible influence for the production of pottery from the Narva to the Ertebølle hunter-gatherers. Whereas the two pottery traditions were shown to be different with regards to raw materials and manufacture, in this study we further attempt a comparison on the basis of function using a lipid residue analysis approach. The aim is to examine whether typological analogies were based on common functional requirements. This paper presents new evidence for the use of Ertebølle ceramics in the southwest Baltic from the analysis of pottery samples from a number of coastal sites in southern Sweden (Scania) and eastern Denmark (Lolland). Gas chromatography-mass spectrometry (GC–MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-c-IRMS) analysis were performed on the absorbed lipid residues to determine their structural characteristics and the stable carbon isotopic composition of selected fatty acids. Results are discussed and compared with analogous published data of Narva ceramics from Estonia. Data from other coastal sites in Denmark and northern Germany are also included for wider comparison. Based on our findings, we conclude that despite little variability in the isotope values of residues, Ertebølle and Narva pots did not serve the same functional demands, and different motives led to their production. Whilst the Narva ceramics appear to have had a specialized role in processing aquatic products, the Ertebølle were more multi-purpose vessels, used also for terrestrial animal and plant resources.

• The impact of environmental change on the use of early pottery by East Asian hunter-gatherers

  2018. Alexandre Lucquin (et al.). Proceedings of the National Academy of Sciences of the United States of America 115 (31), 7931-7936

  Article

  The invention of pottery was a fundamental technological advancement with far-reaching economic and cultural consequences. Pottery containers first emerged in East Asia during the Late Pleistocene in a wide range of environmental settings, but became particularly prominent and much more widely dispersed after climatic warming at the start of the Holocene. Some archaeologists argue that this increasing usage was driven by environmental factors, as warmer climates would have generated a wider range of terrestrial plant and animal resources that required processing in pottery. However, this hypothesis has never been directly tested. Here, in one of the largest studies of its kind, we conducted organic residue analysis of >800 pottery vessels selected from 46 Late Pleistocene and Early Holocene sites located across the Japanese archipelago to identify their contents. Our results demonstrate that pottery had a strong association with the processing of aquatic resources, irrespective of the ecological setting. Contrary to expectations, this association remained stable even after the onset of Holocene warming, including in more southerly areas, where expanding forests provided new opportunities for hunting and gathering. Nevertheless, the results indicate that a broader array of aquatic resources was processed in pottery after the start of the Holocene. We suggest this marks a significant change in the role of pottery of hunter-gatherers, corresponding to an increased volume of production, greater variation in forms and sizes, the rise of intensified fishing, the onset of shellfish exploitation, and reduced residential mobility.

• MALDI‐FT‐ICR‐MS for archaeological lipid residue analysis

  2017. Ester Oras (et al.). Journal of Mass Spectrometry 52 (10), 689-700

  Article

  Soft‐ionization methods are currently at the forefront of developing novel methods for analysing degraded archaeological organic residues. Here, we present little‐used soft ionization method of matrix assisted laser desorption/ionization‐Fourier transform‐ion cyclotron resonance‐mass spectrometry (MALDI‐FT‐ICR‐MS) for the identification of archaeological lipid residues. It is a high‐resolution and sensitive method with low limits of detection capable of identifying lipid compounds in small concentrations, thus providing a highly potential new technique for the analysis of degraded lipid components. A thorough methodology development for analysing cooked and degraded food remains from ceramic vessels was carried out, and the most efficient sample preparation protocol is described. The identified components, also controlled by independent parallel analysis by gas chromatography‐mass spectrometry (GC‐MS) and gas chromatography‐combustion‐isotope ratio mass spectrometry (GC‐C‐IRMS), demonstrate its capability of identifying very different food residues including dairy, adipose fats as well as lipids of aquatic origin. The results obtained from experimentally cooked and original archaeological samples prove the suitability of MALDI‐FT‐ICR‐MS for analysing archaeological organic residues. Sample preparation protocol and identification of compounds provide future reference for analysing various aged and degraded lipid residues in different organic and mineral matrices.

• A Novel Method to Analyze Social Transmission in Chronologically Sequenced Assemblages, Implemented on Cultural Inheritance of the Art of Cooking

  2015. Sven Isaksson (et al.). PLoS ONE 10 (5)

  Article

  Here we present an analytical technique for the measurement and evaluation of changes in chronologically sequenced assemblages. To illustrate the method, we studied the cultural evolution of European cooking as revealed in seven cook books dispersed over the past 800 years. We investigated if changes in the set of commonly used ingredients were mainly gradual or subject to fashion fluctuations. Applying our method to the data from the cook books revealed that overall, there is a clear continuity in cooking over the ages - cooking is knowledge that is passed down through generations, not something (re-) invented by each generation on its own. Looking at three main categories of ingredients separately (spices, animal products and vegetables), however, disclosed that all ingredients do not change according to the same pattern. While choice of animal products was very conservative, changing completely sequentially, changes in the choices of spices, but also of vegetables, were more unbounded. We hypothesize that this may be due a combination of fashion fluctuations and changes in availability due to contact with the Americas during our study time period. The presented method is also usable on other assemblage type data, and can thus be of utility for analyzing sequential archaeological data from the same area or other similarly organized material.
