Ricardo’s Law of Comparative Advantage in Bronze Age, Iron Age, and Early Historic Mainland Southeast Asian Metallurgy: Copper-base Metal Production, Exchange, and Consumption Behaviours at Khao Sai On, Nil Kham Haeng, Non Pa Wai, Phromthin Tai, Sab Champa, and Tha Kae in Central Thailand

Since its late 1970s to early 1980s discovery, the Khao Wong Prachan Valley (KWPV) of central Thailand has been assumed to have been a major supplier of copper in Bronze Age, Iron Age, and Early Historic Southeast Asia. KWPV was the first regional metal production system to be characterised by lead isotope (LI) analysis in the late 2000s, revealing a coherent signature easily distinguished from subsequent analyses of production systems at Phu Lon (northern Thailand) and the Vilabouly Complex (central Laos). Despite KWPV’s scale of production, its LI signature has scarcely been detected at Bronze Age metal consumption sites in nearby northeast Thailand and not at all in Iron Age assemblages. We study copper production and copper/bronze consumption behaviours of Iron Age and Early Historic sites in KWPV’s immediate vicinity: Khao Sai On, Phromthin Tai, Tha Kae, and Sab Champa. Khao Sai On and Phromthin Tai production signatures are highly consistent with those previously established, while the uranogenic tendency at Tha Kae explains outliers from Bronze Age Non Pa Wai and Nil Kham Haeng. Analysis of consumption assemblages reveals little to no consistency with local production signatures. This tendency was tested with LI Iron Age and Early Historic datasets for Ban Khu Muang, Ban Mai Chaimongkol, Ban Pong Manao, and Ban Pong Takhob. The pattern is clear: central Thai populations imported copper/bronze, potentially from the Vilabouly Complex or production loci with closely comparable signatures. We examine this counterintuitive behaviour inductively using Ricardo’s Law of Comparative Advantage combined with a technological appreciation of the relatively low productivity of central Thai primary copper production. This suggests central Thailand’s unattached copper producers freely exchanged copper for exotic goods (bronze, glass, semi-precious stone), with potentially poor terms of exchange, from their desire to participate in wider regional trends in conspicuous consumption.

One Thousand Years of Mediterranean Silver Trade to the Levant: A Review and Synthesis of Analytical Studies

AbstractSilver exchanged by weight for its intrinsic value was the most important measure of value and means of payment in the southern Levant, starting from the Middle Bronze Age II–III through the Iron Age (~1700/1650‒600 BC). Since silver is not available locally in the Levant, its ongoing use as currency in the region triggered long-distance trade initiatives, and its availability or lack thereof had a direct impact on the economy. The continued use is evidenced in 40 silver hoards found in various sites across the region. A comprehensive study of lead isotopes and chemical analyses of samples obtained from 19 hoards enabled us to trace the origin of silver in the millennium during which it was extensively used as currency in the southern Levant and to identify constantly changing silver sources and concomitant trade routes. The results indicate that silver originated initially in Anatolia and Greece (~1700/1650–1600 BC) and shortly after from an unknown location in the Aegean/Carpathian/Anatolian sphere (~1600–1200 BC). After the collapse of Late Bronze Age Mediterranean trade routes, during Iron Age I (~1200–950 BC), there was a period of shortage. Silver trade was revived by the Phoenicians, who brought silver to the Levant from Sardinia and Anatolia (~950–900 BC), and later from Iberia (~900–630 BC). Further change occurred after the Assyrian retreat from the Levant, when silver was shipped from the Aegean (~630–600 BC). Following the devastation caused by the expanding Babylonian empire, silver consumption in the Levant practically ended for a century. Considering the isotopic results, combined with a detailed study of the context, chronology, and chemical composition, we demonstrate that all these factors are essential for the reconstruction of developments in the supply of silver in the southern Levant, and more generally. The changes in trade routes closely follow political and social transformations for over a millennium; exchange in this case was not only, not even mainly preconditioned by the environmental/geographic circumstances, as has often been argued for the Mediterranean. From an analytical point of view, we offer a protocol for the provenance of silver in general.

Beyond ‘Community Craft Specialisation’ in Prehistoric Mainland Southeast Asian Metallurgy: Copper Smelting Behaviours at Khao Sai On, Nil Kham Haeng, Non Pa Wai, Phromthin Tai, and Tha Kae in Central Thailand

Archaeology in Lopburi Province has been under long-term development since the 1970s and has led to the discovery of Khao Wang Prachan Valley (KWPV) as one of three currently known primary copper production (mining and smelting) sites in Southeast Asia. However, since the 1980s, archaeometallurgical research has focused mainly on the two sites of Non Pa Wai (NPW) and Nil Kham Haeng (NKH), dated from the Neolithic (ca. 1800 B.C.) to Early Iron Age (ca. 2300 B.C.), that are known to have large sequences of archaeological material linked to copper production. Although other sites with evidence of copper production are known in this restricted geographical area, their assemblages have not previously been subjected to archaeometric study. This article discusses the results of archaeometallurgical analyses of slags from Khao Sai On (KSO), Tha Kae (TK), and Phromthin Tai (PTT) with sequences dated during the Middle-Late Iron Age. Slag analysis reveals that different smelting behaviours were occurring at these sites. One heterogenous smelting behaviour at Khao Sai On was probably linked to a smaller community practicing metallurgy among other activities, while Phromthin Tai shows more homogeneous production linked to a larger settlement. Although these three sites are located within 26 km of each other, smelters were probably exploiting different local copper deposits around KWPV. The results seem to support a community based type of production where production behaviours are linked to local geology, technical competence, and intensity of exploitation.

Circular settlements of the Trans-Urals and Western Siberia from the Neolithic to the early iron age

Circular in plan fortified settlements, or ring settlements, were an ideal type of lowland fortifications. One of their prototypes is unfortified settlements with a closed layout of dwellings in a circle and an oval. In the north of Eurasia, ring fortifications emerged in the Neolithic (6th–4th millennia BC), in the fisher-hunter-gatherers’ communities in the taiga area of the Ob’ River Basin and the mountain-forest Trans-Urals, during the mass settlement of these territories in the context of global warming. In the Bronze Age (late 3rd – early 1st millennium BC), such fortified settlements, as well as promontory and riverside fortified settlements, disappeared in the taiga giving way to large earth-timber fortified dwellings. At the beginning of the Bronze Age, during the next xerotherm, in the steppes of the Trans-Urals, pastoralists who migrated from South-Eastern Europe erected circular fortresses (the Sintashta culture of the 21st–18th centuries BC). Probably, the construction of circular in plan unfortified settlements of the Tashkovo culture in the forests of the Lower Tobol region in the 21st/20th – 16th centuries BC was influenced by the steppe defensive architecture. The earliest taiga fortified settlements were developing independently of the forest-steppe and steppe settlements. The former and the latter alike were economic, industrial, social and, possibly, cult centres of communities. A new mass distribution of ring settlements in the forest-steppe area of the Tobol-Irtysh region, and later in the taiga area of the Surgut and Lower Ob’ River region, took place at the end of the Bronze Age and the beginning of the Iron Age (8th/7th centuries BC – 3rd/4th centuries AD). In the 6th/5th centuries BC – 3rd/4th centuries AD, the defensive systems of some West Siberian fortifications were supplemented with bastion-tower elements borrowed from the Saka people of the Aral Sea region.

Radiating Encouragement: Further Investigation Into the Application of Gamma Ray Spectroscopy for Archaeological Prospection at the Roman Town of Silchester

ABSTRACTThis study builds on a preliminary investigation into the efficacy of gamma radiation surveying as a complementary tool for archaeological prospection. Improved surveying and data processing methods were implemented, including the use of a vehicle‐mounted Groundhog surveying system, use of alternative software tools and examination of the impacts of individual radionuclides. The study focuses on a range of targets within Insulae VII, XXXV and XXXIII in Silchester Roman town, Hampshire. Targets of interest included a polygonal temple, a house, ditches (including an Iron Age defensive ditch) and several Roman roads. While the survey revealed no measurable differences in the gamma radionuclide content of less substantial structures (such as the temple and house) and the surrounding soil, it successfully delineated major structures. The Roman roads, Iron Age defensive ditch and potentially an indication of a historic field boundary not present in modern records were clearly visible in the generated visualisations. The roads and field boundary appear as distinct linear features of depleted radioactivity. The location of the Iron Age ditch correlates with an area of elevated radioactivity. Notably, the technique not only successfully identified archaeological features but was also able to indicate differences in the properties of similar targets such as variations in road thickness. Further, the gamma radiation data indicates variations in the local geology attributable to historic changes in land use and geochemical composition. This latest study corroborates the findings of the preliminary investigation, demonstrating replicability, scalability and ability to enhance output data quality. Further research, including sampling and non‐destructive analysis of materials from the site, is needed to better explain observed results.

Far away from home? Ancient DNA shows the presence of bicolored shrew (Crocidura leucodon) in Bronze Age Denmark.

An excavation of an Early Iron Age village near Aalborg in Denmark uncovered the jaws and skull fragments from a small mammal that were morphologically identified to the genus Crocidura (white-toothed shrews). Three Crocidura species are known from prehistoric continental Europe but none of them are distributed in Scandinavia, which is why this surprising finding warranted further analyses. The bone was radiocarbon-dated to 2840-2750 calibrated years before present (cal. BP), corresponding to the Late Bronze Age and hence earlier than the Iron Age archeological context in which it was found. Using highly optimized ancient DNA protocols, we extracted DNA from one tooth and shotgun-sequenced the sample to reconstruct a near-complete mitochondrial reference genome (17,317 bp, 32.6× coverage). Phylogenetic analyses determined this specimen as a bicolored shrew (Crocidura leucodon) but with a phylogenetic position basal to the clade of known sequences from this species. The confirmation of Crocidura presence in Denmark by the Late Bronze Age sheds new light on the prehistoric natural history of Scandinavia. We discuss the implications of this finding from both zoo-archeological and ecological perspectives. Furthermore, the mitochondrial genome reconstructed in this study offers a valuable resource for future research exploring the genetic makeup and evolutionary history of Eurasian shrew populations.

‘Who is afraid of fairenesse or wanton ladies appearing in their barenesse?’: laughing at female desire in early modern English reception of the myth of the Trojan War☆

AbstractIn early modern England, as part of a broader interrogation of exemplarity, full‐scale works on the Trojan War often subjected the myth's heroes to humorous scrutiny, whereas the heroines remained surprisingly untouched by comedy. Testifying to the war's calamities already in antiquity, in the early modern period, the myth's women acquired a further link to destruction: their sexuality was believed to ‘undo’ men. Embodying different types of suffering, the heroines came to be regarded as inherently tragic. Read against this context, one aspect of William Shakespeare's and Thomas Heywood's interventions into the myth appears remarkably defiant. Pursuing divergent aims – in Troilus and Cressida Shakespeare explores the annihilating power of laughter irrespective of gender, in Oenone and Paris and The Iron Age Heywood specifically sets out to rehabilitate female characters – both authors temporarily turn the heroines into objects of comedy. However, if Shakespeare creates a Troy in which mockery is universal, Heywood does not. Thus, although both maintain that laughter against the myth's heroines ultimately backfires, turning those laughing into comic figures, Heywood, by having the women never resort to mockery, makes them seem more sympathetic, even tragic, whereas their Shakespearean counterparts laugh and suffer laughter's consequences alongside men.

Ancient genomic analysis of a Chinese hereditary elite from the Northern and Southern Dynasties

China's Northern and Southern Dynasties period (3rd-6th centuries AD) marked a significant era of ethnic integration in northern China. However, previous ancient DNA studies have primarily focused on northern ethnic groups, with limited research on the genetic formation of the hereditary elite family, especially considering their abundant archeological record and clear material identity. In this study, we obtained the ancient genome of a hereditary elite family, Gao Bin (高宾, 503-572 AD), at 0.6473-fold coverage with 475132 single-nucleotide polymorphisms (SNPs) on the 1240k panel. His mitochondrial haplogroup belonged to Z4 and Y-haplogroup to O1a1a2b-F2444∗. The genetic profile of Gao Bin was most similar to that of the northern Han Chinese. He could be modeled as deriving all his ancestry from Late Neolithic to Iron Age Yellow River farmers without influence from Northeast Asia, Korea, or the Mongolian Plateau. Our study sheds light on the genetic formation of hereditary elite families in the context of the Southern and Northern Dynasties ethnic integration.

SALTOV POTTERY IN MOKHNACH P SETTLEMENT

The pottery of the Saltiv cultural-historical community period (8th — mid-10th centuries) found in Mokhnach-P settlement is analyzed in the paper. This settlement is the best researched one in the microregion of the hillfort Mokhnach, Chuhuiv district in Kharkiv region. The settlement was a part of the Khazar Khaganate forest-steppe territory at the late 1st millennium AD. All pottery found in the settlement was wheel-made. The traces of local ceramic manufacture, such as two pits for clay homogenization, pointed to this fact. However, it related to the production of the most popular ceramic categories (cooking pots) and was at the level of homemade manufacturing. High-quality imported pottery occupied a dominant position. It was supplied from the Northern Pontic region and neighboring pottery centers of the Khaganate’s forest-steppe. The tableware set was of high quality and diversity. Almost all of its groups and categories are mentioned here. Tare pottery are presented by amphorae, big tare pithoi, hydria, flasks and big ceremonial pithoi. Pots and jugs can be found among cooking ceramics. Tableware includes jars, mugs, kubyshkas, table pithoi, pots, and also a ceremonial vessel with two containers. Form and ornamentation of these vessels are traditional and have a lot of analogies to all territories of the Saltiv cultural-historical community. The peculiarity of the local ceramic complex is in the extremely small amount of remains of thick-walled tare pithoi made of chamotte clay for grain storage. Other features include a lot of high-quality ceremonial pithoi and separate rare ornaments on cooking pots. The volume of pots indicates the domination of a small couple family; it completely correlates with a tiny useful amount of the researched dwellings here. The only vessel with two containers belongs to an extremely limited category of ceremonial and cult ceramics, and has a very restricted range of analogies, mostly on Saltiv sites of the Siverskyi Donets. It reflects the traditions and culture of Iranian-speaking, Turkic and also Caucasian nations, beginning, at least, from the early Iron Age. These vessels could be used in a ritual of fraternity, inter-family reconciliation, and also could serve as an honorable drinking bowl for the most respected guest during a feast.

The Geochemistry of Unalloyed Copper Metallurgical Group Indicates Copper Ore Sources in the Late Bronze and Early Iron Ages of the Urals

Trace elements in copper artifacts from Late Bronze and Early Iron Age sites in the Urals, formerly attributed to the metallurgical group of “chemically pure” copper, were analyzed using the method of laser ablation inductively coupled plasma mass spectrometry. The metal of which artifacts included in this group are made reveals geochemical markers suggesting that “pure” copper actually falls into several subgroups. The PCA analysis of the results identifies 11 clusters corresponding to various sources of copper ores and their mixtures. At least seven principal associations can be linked to copper deposits of different geological types and origin: Au-Te-Bi, Au-Se-Te-Sb, Fe-Co-Ni-As-Sb, Fe-Co-Ni -Zn, Se-Co-Fe, Ag-Pb-Ni, and Sb-Pb-Zn-As. Also, several mixed associations reflect the fusion of copper items and metal scrap initially obtained from different sources: Sn-Pb, Fe-Co-Ni-Zn + Sn, Fe-Co-Ni + Au-Te-Bi-Ag, Fe-Co-Ni + Au-Te-Bi + Sn. A separate association, for which the ore source remains unknown, consists of artifacts characterized by a low content of trace elements, jointly making up less than 0.01 wt%. The largest sample in the Late Bronze Age “pure copper” group falls within the Sn-Pb cluster representing a mixture of local copper and imported Sn-containing copper scrap. Judging by trace elements, the main sources of ore in the “pure copper” group of the Itkul and Sarmatian cultures were the Gumeshki mine and another unidentified source. Both could have been used already in the Final Bronze Age.

Holocene history of the Kungur forest-steppe (cis-Urals, European Russia): case study Uinskoe mire

The formation and development of the Kungur forest-steppe has been a controversial topic for almost 150 years due to its location within the belt of hemiboreal forests in the pre-Urals of European Russia. To further the knowledge on its manmade versus natural origin we conducted a palaeoecological study reconstructing the regional vegetation history in the Mid-Kama region as well as local bog development and additional archaeobotanical studies nearby. Detailed loss-on-ignition analysis, peat properties and high resolution radiocarbon dating were carried out to obtain long-term carbon accumulation rate estimates. The data document the presence of the pine-dominated forest-steppe with spruce and birch during the major part of the Holocene (∼9.7–5.5 ka) and the development of the modern hemiboreal forests from 5.5 ka onwards. Since 3.5 ka, the hemiboreal forests were increasingly influenced by human action, corresponding to the development of local archaeological cultures. The earliest human impact is observed during the Garinskaya culture (4.5–3.5 ka). It increased during the Early Iron Age with the Ananyino (2.8–2.2 ka) and Glyadenovo (2.2–1.6 ka) cultures and during the Medieval with the Nevolino culture (1.6–1.1 ka). Archaeobotanical data reveal consumption of Triticum aestivum and T. aestivum/spelta by bearers of the Nevolino culture as well as a local cultivation of emmer. The formation of the recent Pinus-Betula forest-steppe took place in the last 300 years during the Russian colonisation. In conclusion, continental and warm climatic conditions as well as fire activities were maintaining semi-open landscapes of the forest-steppe during the Early and Middle Holocene, while land use became the dominant factor since 3.5 ka.

ИСТОРИЯ ИЗУЧЕНИЯ ПОСЕЛЕНЧЕСКИХ ПАМЯТНИКОВ САРМАТСКОГО ВРЕМЕНИ В ЛЕСОСТЕПНОМ ПОДОНЬЕ

The article reveals the history of the study of hillforts and settlements of the first centuries AD on the Upper Don. The author substantiates the identification of three chronological stages in the history of settlement archeology of the Upper Don region. The first of them is associated with pre-revolutionary studies of local history societies, as well as with the work of the Upper Don expedition in the Lipetsk region and the expedition of the Voronezh State University in the Voronezh region. At this time, the process of accumulation of material from the first centuries took place, and its interpretation was limited to the term “early Iron Age”. The second stage of research began in 1978 with the creation of the Scythian-Sarmatian brigade of VSU (A.P. Medvedev) and its targeted study of burial mounds and settlements of the Sarmatian period in the forest-steppe Don region. During the same period, work was carried out by the LGPI expedition (A.N.Bessudnov), State Directorate for the Protection of Cultural Heritage of the Lipetsk Region (I. E. Biryukov, I. A. Kozmirchuk), as well as employees of the Department of Archaeology and History of the Ancient World of VSU (Yu. D. Razuvaev, M. V. Tsybin, A. S. Savrasov, A. D. Pryakhin, N. A. Tropin, etc.). The third stage is distinguished by the work of both scientific expeditions (A. M. Oblomsky, I. E. Biryukov, G. L. Zemtsov, Yu. D. Razuvaev, D. V. Akimov, etc.) and protective archaeological excavations. Discussions on the identification of groups of hillforts and settlements of the Sarmatian period are considered, and controversial issues of their dating are identified. From the historiographical analysis of the current state of the problem, further directions of its research logically follow: highlighting the cultural uniqueness of the settlements of the Upper Don and, especially, their chronology.

Food offerings and firewood: Integrated archaeobotanical analyses of seed/fruit and wood charcoal remains from a Hellenistic-Roman Cemetery on Tinos Island, Cyclades

Archaeobotanical studies have already been widely and successfully used in Greece for the Neolithic to Iron Age periods, yet they were mostly omitted in Classical archaeology. This was justified by the existence of ancient texts, that provide information on plant use in Antiquity. However, not every aspect of life and plant use is described in ancient texts, and additionally, research of past vegetation relies solely on the studies of plant remains. A rescue excavation of a Hellenistic-Roman cemetery with pyres and graves on Tinos Island in the Cyclades provided not only charred seeds/fruits and leaves, but also large amounts of charcoal. The material enabled the study of food offerings / grave goods of plant origin, as well as the choice and availability of fuel wood for cremations. The olive (Olea europaea) seems to have been an important food crop on the island, as it was found in high quantities, accompanied by barley (Hordeum vulgare) and other cereals (Cerealia), as well as cereal products (ACO = amorphous charred objects), figs (Ficus carica) and grapes (Vitis vinifera). Fuel wood for the cremations was mainly based on evergreen oak (Quercus sect. Ilex) and olive wood (Olea europaea), the latter probably deriving from prunings produced in olive groves. Other macroremains, such as a leaf of kermes oak (Quercus coccifera), myrtle charcoal (Myrtus communis) and heather leaves (Erica manipuliflora) point to fuel harvest in Phrygana shrubland, which is the main vegetation form found on the island today.

Back to black: Analysis of the earliest natron glass found in Italy

An assemblage of black-appearing glass objects (predominantly beads) that is dated to the 9th–7th centuries BCE and found in Iron Age contexts of Southern Etruria and Latium (central Italy) was analysed using portable X-ray fluorescence spectrometry, laser ablation – inductively coupled plasma – mass spectrometry and micro-Raman spectroscopy. The analytical approach allowed us to discuss the technology of glass-making in a period of relevant technological changes. It resulted that the glass that reached the Italian peninsula was somewhat different, from a compositional point of view, from both earlier and later periods. The data collected showed that iron – the main colouring agent for these glasses – was obtained from several sources as was silica – the main component of glass. Lime, one of the main constituents of many types of glass, plays a modest role in this assemblage, which places these samples in a special position because of the peculiar batch formula. At least three centres of raw glass production are suggested by the compositional data, but in each case the glass was imported to the Italian peninsula.

Bronze Anklets from Ḥorvat Tevet (Jezreel Valley): New Light on Exchange and Identity Construction in the Iron I

ABSTRACT This article presents the results of lead isotope analysis (LI) conducted on four bronze anklets from an early Iron Age burial (Burial D/F3) at the site of Ḥorvat Tevet, Israel. The results show that the copper in these items most likely originated in Timna. All the known LI data from the Late Bronze and early Iron Age southern Levant is then plotted to demonstrate that Arabah copper dominated the region in the early Iron Age. The significance of these objects for reconstructing exchange networks in the early Iron Age Jezreel Valley is briefly explored. We then turn to discussing the social meaning of these objects. Based on a catalogue of all known southern Levantine burials dated between the Late Bronze III (12th century bce) and Iron IIA (9th century bce) containing anklets or bracelets in association with skeletal remains with biological sex and age determinations, we conclude this was likely the burial of a high-status female.

Amber provenance as a Chrono-Cultural Proxy: Insights from FTIR analysis in the Iberian Peninsula

In recent years, significant advancements have occurred in our comprehension of amber consumption patterns in the Iberian Peninsula. This progress stems from the increasing volume of FTIR data related to both archaeological and geological amber. Consequently, a chronological model has been established, delineating amber consumption in the Iberian Peninsula from the Late Paleolithic to the Iron Age. Broadly, local amber consumption has been minimal since the Paleolithic period. Sicilian amber makes its appearance in Iberia around the 5th millennium BCE and fades away in the 2nd millennium BCE, giving way to Baltic amber, which has remained the sole source since then.The well-defined chronological model, the abundance of FTIR provenance data, and the infrequent association of amber with absolute or relative dates prompt us to explore whether provenance can serve as a chrono-cultural proxy for amber beads.This study introduces new amber finds, presents fresh FTIR data on archaeological amber ornaments, and incorporates minor updates and bug fixes to the general catalog. It is the outcome of a thorough bibliographic review and on-site analysis and examination of the beads.The results obtained in this study enable the reconstruction of amber consumption throughout Iberian prehistory, drawing on 29 newly FTIR-analyzed ambers from 9 sites. Our findings expand the empirical foundation, facilitating the confirmation of diachronic changes in amber consumption. Importantly, they affirm that amber provenance can indeed be employed as a viable chrono-cultural proxy.

Iron Age ceramics from Thracian rock-cut complexes from Bulgaria – Mineral magnetic relics of technological production and use

The Gluhite kamani Thracian rock-cut complex in the Eastern Rhodopes Mountain is famous with its more than 500 rock niches carved in the rock at heights up to 20 m. Continuous habitation starting from the final Chalcolithic (the second quarter of the 4th millenium BCE) until the Late Classical – Early Hellenistic period (late 5th – 4th century BCE) provides unique opportunity for studying diachronic changes in pottery production and use. In this contribution, systematic analysis of a collection of 135 ceramic sherds from five archaeological periods at the site was carried out using a combined mineral magnetic and geochemical approach. Magnetic susceptibility (χ), frequency-dependent magnetic susceptibility (χfd%) and firing temperature (Tfire), determined using the magnetic susceptibility method, were combined with data from elemental XRF analyses. Thermomagnetic measurements, employed for identification of magnetic minerals revealed the dominant presence of (titano)magnetite with low Ti-content and/or a fraction of single-domain magnetite and in few cases hematite. Although varying in a wide range, median χ values of ceramic sherds from the Early Iron Age (EIA) periods show similar distribution, while for Late Iron Age (LIA) with the introduction of the wheel-thrown pottery, χ values are higher, presumably due to decreased amount of silica-rich clastics in the clay. Concurrently, χfd% values decrease in ceramics from the LIA, indicating predominant presence of stable single-domain magnetite in the iron oxide composition of the ceramics. Firing temperatures (Tfire) estimations display a systematic pattern of two groups – higher (Tfire between 760 and 800 °C) and lower (Tfire ∼ 400–––600 °C). During the EIA periods both Tfire groups are present, characterized by systematic gradual decrease of the median value of the low Tfire when going from EIA1 towards the EIA2. Wheel-thrown pottery from the LIA show low Tfire ∼ 400 °C only. Based on the differences in thermomagnetic properties of ceramics, their magnetic parameters and Tfire estimates, two possible hypotheses are suggested to explain the observed changes in EIA ceramic characteristics: i) utilization of two differently sourced clay materials (illite-dominated and montmorillonite-dominated) for production of ceramics fired at higher and lower temperatures, respectively; and ii) utilization of one raw clay source, while using two firing regimes – firing at higher temperature for prolonged time, and fast firing to high temperature with successive stage of longer firing at lower temperature. Differences in thermomagnetic properties of wheel-thrown pottery from the LIA period leads to the assumption for utilization of diverse clay source for their production, as compared clay sources for the Early Iron Age periods.

From Ponds to Pine Plantations in 9000 Years: The Environmental Archaeology of Beck Burn, Solway Moss, Cumbria

ABSTRACT This article explores the evidence for environmental change at Beck Burn, Solway Moss, on the English/Scottish border. The analysed pollen, non-pollen palynomorphs (NPP) and microscopic charcoal particles permit several palaeoenvironmental events to be interpreted, supported by radiocarbon dating. These and previously published data suggest the presence of very early Mesolithic water-edge activity, later Mesolithic woodland management, clearance and small-scale cultivation during the early Neolithic period, followed by low-level disturbance for pastoral farming in the early Bronze Age. Woodland clearance and cereal cultivation are dated to the middle Bronze Age, with significant clearance and cultivation identified during the late Iron Age or early Roman period. The medieval period is characterised by evidence for a mixed subsistence economy, with reduced activity possibly coincident with the Wars of Scottish Independence, famines and the Black Death of the fourteenth century, as well as the Little Ice Age. Renewed activity, with evidence for both arable and pastoral farming, is dated to the late medieval to early post-medieval period. Pine plantations were then created, possibly in the eighteenth century or later. The data reveal the importance of palaeoenvironmental archaeology, in the absence of significant finds or features, in creating a link with the past.

Geographic origin, ancestry, and death circumstances at the Cornaux/Les Sauges Iron Age bridge, Switzerland

Cornaux/Les Sauges (Switzerland, Late Iron Age) revealed remnants of a wooden bridge, artifacts, and human and animal skeletal remains. The relationship between the collapsed structure and the skeletal material, whether it indicates a potential accident or cultural practices, remains elusive. We evaluate the most plausible scenario for Cornaux based on osteological, taphonomic, isotopic, and paleogenomic analysis of the recovered individuals. The latter amount to at least 20 individuals, mostly adult males. Perimortem lesions include only blunt force traumas. Radiocarbon data fall between the 3rd and 1st c. BCE, although in some cases predating available dendrochronological estimates from the bridge. Isotopic data highlight five to eight nonlocals. No close genetic relatedness links the analyzed skeletons. Paleogenomic results, the first for Iron Age Switzerland, point to a genetic affinity with other Central and Western European Iron Age groups. The type of skeletal lesions supports an accidental event as the more plausible explanation. Radiocarbon data and the demographic structure of the sample may suggest a sequence of different events possibly including executions and/or sacrifices. Isotopic and paleogenomic data, while not favoring one scenario over the other, do support earlier interpretations of the last centuries BCE in Europe as a dynamic period from a biocultural perspective.
