Homogénéité ou hétérogénéité dans le métal des dépôts de l’Âge du Bronze : estimations sur leur formation à partir des isotopes du plomb

Lead isotope analysis was applied to three representative Late Bronze Age hoards from the Iberian Peninsula, for all of which compositional analyses are available. Unpublished isotopic evidence from the cave of Muricecs (Lleida) and the settlement of Las Lunas (Toledo) are compared to the published results for weapons from the Ría de Huelva, one of the most important Late Bronze Age hoards from Western Europe. Lead isotope analysis can tell us the sources of the metal used to make the artifacts in each hoard. The limited number of geologic reference points makes it difficult to determine all of the ore sources, but the analyses do give us evidence about the degree of homogeneity of the metal in the artifacts. As a result, one can separate metallic composition from artifact typology and thereby evaluate how the hoards were formed and what their functions were. Elemental analysis is unsuitable for this purpose because Late Bronze Age metals from Iberia are very homogenous and have few impurities.     

Lallemantia, an imported or introduced oil plant in Bronze Age northern Greece

This paper reports on seeds of Lallemantia (Lamiaceae) found at Bronze Age sites in northern Greece. At several of these sites, the seeds were found in significant concentrations in storage contexts, suggesting that they were deliberately stored for use by the inhabitants. Oil from the seeds of Lallemantia can be used for a variety of purposes, including food, lighting and medicine. This genus is not native to Greece, the nearest modern occurrences of Lallemantia species being in Anatolia from where they extend further east as far as Iran, or beyond. To date, it has not been found in Neolithic deposits in Greece, despite significant archaeobotanical research, especially in northern Greece. This suggests that it first appeared in Greece in the early Bronze Age, and indicates long distance contacts with communities to the east or north at this time. It is difficult to establish whether its continued use indicates that seeds of this genus were repeatedly brought into Greece throughout the Bronze Age or that the genus was introduced in the early Bronze Age and then locally cultivated. The presence of seeds, however, may suggest that Lallemantia was locally cultivated, as it would have been possible to import it in the form of oil. The appearance of a new import or introduction at this time adds to the evidence for external contact during the Bronze Age. Lallemantia may have been part of a group of oil producing taxa which became significant during the Bronze Age in northern Greece paralleling the increased importance of the olive in southern Greece.     

The oldest evidence of Nigella damascena L. (Ranunculaceae) and its possible introduction to central Europe

After the beginning of metal processing at the transition from the Neolithic to the Bronze Age, further knowledge of ore mining and smelting had spread from the Near East to central Europe. In the copper ore deposits of Schwaz, in the central part of the Alps, the oldest traces of copper mining derive from the early to middle Bronze Ages. Investigation of a middle to late Bronze Age (1410–920 cal B.C.) slag-washing site in the area revealed a carbonised seed of Nigella damascena (Ranunculaceae) (love-in-a-mist) together with individual other food plants. The plant remains had become incorporated into the slag sediments by chance and had been preserved in an excellent state due to toxic copper salts contained in the soil. Nigella damascena, like N. sativa (black cumin), is traditionally used as a condiment and healing herb in southern Europe and the Near East, but has never grown in the wild in central Europe. Until now, there has been no evidence of prehistoric large-scale cultivation of N. damascena in central Europe. This leads to two possible conclusions: the find may either originate from an exchange of goods with the cultures in the Mediterranean during the Bronze Age, or indicate an introduction of the plant by an immigrant population from that area. Implicating the latter alternative together with the archaeological context of the ore processing site suggests that Nigella damascena had been introduced to the Alps by foreign miners in the course of ore exploitation during the middle to late Bronze Age.     

The impact of prehistoric mining activities on the environment: a multidisciplinary study at the fen Schwarzenbergmoos (Brixlegg, Tyrol, Austria)

The exploitation of copper ore deposits of the northern Greywacke Zone was initiated by the implementation of metallurgic technologies in the Eastern Alps thousands of years ago. This multi-proxy study aimed to detect prehistoric mining phases in the vicinity of a prominent copper ore deposit in the Lower Inn Valley. Therefore we studied a peat core from a fen using pollen, micro charcoal and geochemical analyses. In the same fen, an archaeological investigation revealed an ore beneficiation site, well dated by dendrochronological analysis to the Late Bronze Age (9th century b.c.). First hints of mining activities reflected by the occurrence of anthropogenic indicators in the pollen diagram, associated with elevated metal values, at the beginning of the Bronze Age might result from early mineral prospecting and metallurgical experiments around the use of fahlore. The local ore deposit was then abandoned until during the Bronze Age mining activities started to increase. This is reflected by an expansion of the pioneer species Pinus and Larix on mine spoil heaps in the proximity. Concomitantly metal ratios and micro charcoal increase. From about 1000 to 850 b.c. a strong impact of mining activities is displayed in the multi-proxy data. The local forest was partly cleared on and in the vicinity of the fen. According to dendrochronological data the ore beneficiation plant was in use from about 900 to 870 b.c. Until about 700 b.c. another period with moderate impact by mining activities in the further vicinity of the fen shows up.     

Environmental impact of neolithic and bronze age farming in the eastern Pyrenees forelands, based on multidisciplinary investigations at La Caune de Bélesta (Bélesta Cave), near Perpignan, France

Results of multidisciplinary studies, involving anthracology, archaeology and geoarchaeology, that have been carried out on Neolithic to Bronze Age deposits from Bélesta Cave, eastern Pyrenees, are reported. These show that the type of human activity, i.e. pastoralism alone or a more diversified farming economy, and continuity/discontinuity of occupation are the main factors that determine the structure and evolution of the Holocene vegetation in the region. Neolithic pastoral activities were not continuous and so did not have an enduring influence on the natural environment. The more continuous and diversified exploitation associated with Bronze Age cultures was responsible for the development and maintenance of the low garrigues.     

青铜时代中晚期辽西地区农业活动特征

辽西地区城子山遗址和夏家店遗址农作物种子遗存研究显示,城子山地区青铜时代中期以旱作农业种植为主.粟的栽培比例要明显高于黍.青铜时代晚期的夏家店地区属半农半牧区,存在黍与粟为主的旱作农业种植,但黍的栽培比例要远高于青铜时代中期的城子山地区.干旱化可能是导致夏家店地区青铜时代晚期黍栽培比例升高的主要原因.城子山和夏家店地区农业种植结构在青铜时代晚期可能已有所不同,但这2个地区农业种植的差异究竟从何时开始,仍是一个需要继续深入研究的问题.

Man and environment around lake Maliq (southern Albania) during the Late Holocene

The archaeological site of Sovjan is located at the edge of lake Maliq. It was occupied from the early Bronze Age to the early Iron Age. Pollen data from a short sequence of peat deposits dated between 4255±50 and 2420±45 uncal B.P. and charcoal, seeds and wood from archaeological deposits have provided new information on human activities in the region. They are discussed in the general frame of agricultural developments in the Balkans. Regional environment (regarding vegetation and hydrology) and climate are also discussed.

Agricultural practices in Arctic Norway during the first millennium b.c.

Palaeoecological investigations of mires suggest that agriculture was established north of the Arctic Circle in Norway during the late Bronze Age (1100?C500 b.c.) and Pre-Roman Iron Age (500?C1 b.c.). The lack of archaeobotanical and archaeological investigations has made it difficult to assess the nature of this early agricultural expansion into the Arctic in any detail. Here we present the first well documented archaeobotanical investigation from north Norway that covers this agricultural pioneer phase. Remains of charred seeds show that barley (Hordeum) was already being cultivated in the late Bronze Age, and that wheat (Triticum) was introduced in the Pre-Roman Iron Age. Large amounts of crowberry (Empetrum) seeds are also typical of the Pre-Roman Iron Age and were obviously an important food plant at the time, at least locally. Charcoal rich layers dated to the late Bronze Age suggest that the local birch forest was initially cleared away with the help of fire, possibly related to a slash-and-burn cultivation practice. Lithostratigraphic and pollen-analytical results indicate that the cultivation practice of the Pre-Roman Iron Age was a form of bush-fallow system with intensive soil re-working alternated with long periods of fallow.     

Genetic Continuity of Bronze Age Ancestry with Increased Steppe-Related Ancestry in Late Iron Age Uzbekistan

Although Uzbekistan and Central Asia are known for the well-studied Bronze Age civilization of the Bactria–Margiana Archaeological Complex (BMAC), the lesser-known Iron Age was also a dynamic period that resulted in increased interaction and admixture among different cultures from this region. To broaden our understanding of events that impacted the demography and population structure of this region, we generated 27 genome-wide single-nucleotide polymorphism capture data sets of Late Iron Age individuals around the Historical Kushan time period (∼2100–1500 BP) from three sites in South Uzbekistan. Overall, Bronze Age ancestry persists into the Iron Age in Uzbekistan, with no major replacements of populations with Steppe-related ancestry. However, these individuals suggest diverse ancestries related to Iranian farmers, Anatolian farmers, and Steppe herders, with a small amount of West European Hunter Gatherer, East Asian, and South Asian Hunter Gatherer ancestry as well. Genetic affinity toward the Late Bronze Age Steppe herders and a higher Steppe-related ancestry than that found in BMAC populations suggest an increased mobility and interaction of individuals from the Northern Steppe in a Southward direction. In addition, a decrease of Iranian and an increase of Anatolian farmer-like ancestry in Uzbekistan Iron Age individuals were observed compared with the BMAC populations from Uzbekistan. Thus, despite continuity from the Bronze Age, increased admixture played a major role in the shift from the Bronze to the Iron Age in southern Uzbekistan. This mixed ancestry is also observed in other parts of the Steppe and Central Asia, suggesting more widespread admixture among local populations.     

Carbonized plant remains from a pre-Roman Iron Age house site at Opperdoes,West Friesland,The Netherlands

The eastern part of the region of West Friesland (The Netherlands) was densely inhabited in the Middle and Late Bronze Age (Hoogkarspel culture). In the whole of this area, Iron Age settlement has only been found around Opperdoes. Carbonized plant remains from features associated with a pre-Roman Iron Age house near Opperdoes are discussed and compared with Bronze Age data from the region. The evidence suggests that the Iron Age food economy was different from that in the Bronze Age. Barley and linseed were possibly imported, while gold-of-pleasure was cultivated at the site.     

Brief communication: diachronic investigation of linear enamel hypoplasia in prehistoric skeletal samples from Trentino,Italy

Linear enamel hypoplasia was scored on Neolithic, Copper Age, and Early Bronze Age samples from the Trentino region, Italy, in order to compare the extent of growth disruption in different biocultural subsistence systems (foragers with little agriculture, to agriculturists and agropastoralists). The Early Bronze Age sample shows a higher frequency of enamel defects and an earlier chronological onset than the early Neolithic sample. The higher frequency of defects in the Bronze Age sample could be linked to less diversified nutrition and, because of increased sedentism, a higher risk of disease.     

The prehistoric hillfort at Grad (Peljesac, Dalmatia)--preliminary results of intensive surface survey

An intensive surface survey, covering an area of approximately 10.000 m2, was carried out at Grad, a hillfort in southern Dalmatia. Its aims were to obtain information relevant for determining the spatial extent of the site, its function(s), periods of occupation, degree of preservation, and potential for further investigation. Research strategy included mapping of the visible structural remains and systematic recovery of all surface finds. Majority of the collected finds are coarse Hellenistic ceramics followed by Bronze Age and Iron Age pottery. The central area of the hillfort was intensively used during the last few centuries B.C., while its origins can be traced back to the Bronze Age. The recorded structures and the recovered finds hint at a residential and defensive function of the site, while its central, elevated area may have been a focus of special activities.     

Plant Resources from the Bronze Age and the first Iron Age in the northwestern arc of the Mediterranean Basin

This paper updates the question of plant resources during the Bronze Age and First Iron Age in the northwestern Mediterranean Basin. Among the cereals, six-row hulled barley is dominant throughout the territory, whereas naked and hulled wheats take on greater or lesser roles from region to region. Millet cultivation developed during the Bronze Age and became widespread in the First Iron Age. Apart from cereals, pulses, oil species and fruit appear to be secondary. Results from the study of archaeobotanical remains on wetland sites, however, lead us to question this finding, as oil plants and fruits are much better represented in waterlogged conditions. The cultivation of vine began in the First Iron Age. In spite of a number of characteristics common to plants throughout the study area, regional differences, evident in the Bronze Age, seem to dissipate in the First Iron Age.

Earliest evidence of a primitive cultivar of <Emphasis Type="Italic">Vitis vinifera</Emphasis> L. during the Bronze Age in Sardinia (Italy)

The discovery of the Nuragic culture settlement of Sa Osa, Cabras-Oristano, Sardinia, has made it possible to investigate the domestication status of waterlogged uncharred grape pips that were recovered from three wells dating from the Middle and Late Bronze Age (ca. 1350–1150 bc). Applying the stepwise linear discriminant analysis method, a morphological comparison of archaeological seeds and modern wild and cultivated Sardinian grapes pips was performed to determine the similarities between them. The results showed that the archaeological seeds from the Middle Bronze Age have intermediate morphological traits between modern wild and cultivated grape pips from Sardinia. In contrast, the analyses performed on the archaeological seeds from the Late Bronze Age showed a high degree of similarity with the modern cultivars in Sardinia. These results provide the first evidence of primitive cultivated Vitis vinifera in Sardinia during the Late Bronze Age (1286–1115 cal bc, 2σ). This evidence may support the hypothesis that Sardinia could have been a secondary domestication centre of the grapevine, due to the presence of ancient cultivars that still exhibit the phenotypic characteristics of wild grapes.     

Ancient DNA reveals traces of Iberian Neolithic and Bronze Age lineages in modern Iberian horses

Multiple geographical regions have been proposed for the domestication of Equus caballus . It has been suggested, based on zooarchaeological and genetic analyses that wild horses from the Iberian Peninsula were involved in the process, and the overrepresentation of mitochondrial D1 cluster in modern Iberian horses supports this suggestion. To test this hypothesis, we analysed mitochondrial DNA from 22 ancient Iberian horse remains belonging to the Neolithic, the Bronze Age and the Middle Ages, against previously published sequences. Only the medieval Iberian sequence appeared in the D1 group. Neolithic and Bronze Age sequences grouped in other clusters, one of which (Lusitano group C) is exclusively represented by modern horses of Iberian origin. Moreover, Bronze Age Iberian sequences displayed the lowest nucleotide diversity values when compared with modern horses, ancient wild horses and other ancient domesticates using nonparametric bootstrapping analyses. We conclude that the excessive clustering of Bronze Age horses in the Lusitano group C, the observed nucleotide diversity and the local continuity from wild Neolithic Iberian to modern Iberian horses, could be explained by the use of local wild mares during an early Iberian domestication or restocking event, whereas the D1 group probably was introduced into Iberia in later historical times.     

Rewriting the Central European Early Bronze Age Chronology: Evidence from Large-Scale Radiocarbon Dating

The transition from the Neolithic to the Early Bronze Age in Central Europe has often been considered as a supra-regional uniform process, which led to the growing mastery of the new bronze technology. Since the 1920s, archaeologists have divided the Early Bronze Age into two chronological phases (Bronze A1 and A2), which were also seen as stages of technical progress. On the basis of the early radiocarbon dates from the cemetery of Singen, southern Germany, the beginning of the Early Bronze Age in Central Europe was originally dated around 2300/2200 BC and the transition to more complex casting techniques (i.e., Bronze A2) around 2000 BC. On the basis of 140 newly radiocarbon dated human remains from Final Neolithic, Early and Middle Bronze Age cemeteries south of Augsburg (Bavaria) and a re-dating of ten graves from the cemetery of Singen, we propose a significantly different dating range, which forces us to re-think the traditional relative and absolute chronologies as well as the narrative of technical development. We are now able to date the beginning of the Early Bronze Age to around 2150 BC and its end to around 1700 BC. Moreover, there is no transition between Bronze (Bz) A1 and Bronze (Bz) A2, but a complete overlap between the type objects of the two phases from 1900–1700 BC. We thus present a revised chronology of the assumed diagnostic type objects of the Early Bronze Age and recommend a radiocarbon-based view on the development of the material culture. Finally, we propose that the traditional phases Bz A1 and Bz A2 do not represent a chronological sequence, but regionally different social phenomena connected to the willingness of local actors to appropriate the new bronze technology.     

Symbolic Metal Bit and Saddlebag Fastenings in a Middle Bronze Age Donkey Burial

Here we report the unprecedented discovery of the skeleton of a ritually interred donkey with a metal horse bit in association with its teeth and saddlebag fastenings on its back. This discovery in the Middle Bronze Age III sacred precinct (1700/1650-1550 BCE) at Tel Haror, Israel, presents a unique combination of evidence for the early employment of equid harnessing equipment, both for chariot bridling (horse bit) and pack animals (saddlebags). The ritually deposited donkey with its unique accoutrements advances our understanding of the broad social and religious significance of equids in the Levantine Bronze Age, previously known mainly from textual and iconographical sources.     

Vegetation change during the Bronze Age studied in a multi-proxy approach: use of wood linked to charcoal analysis

During recent archaeological excavations in the alpine valley of Montafon, western Austria, a Bronze and early Iron Age settlement cluster located at about 1,000 m a.s.l. was excavated. The human impact on the woodland resulting from these prehistoric settlement activities has been evaluated by the analysis of charred plant macro remains from cultural layers from a hilltop settlement site and two other close-by settlements, all of them encompassing the Early and Middle Bronze Age (19th to 15th century cal. b.c.) and early Iron Age (6th/5th century cal. b.c.). Charred seeds and fruits have provided information on the supply of foodstuff while charcoal (anthracological) analyses of firewood have revealed the use of wood and consequently the changes in local woods. The latter analyses suggest that the spruce-fir woodland (Piceeto-Abietetum) was gradually cleared from the Early Bronze Age. During the Middle Bronze Age large amounts of Pinus sylvestris (pine), Betula (birch), Corylus avellana (hazel) and Sorbus (rowan) with some Picea abies (spruce) characterized the woods, and early succession stages indicate clearings. These anthracological studies are corroborated by pollen studies disclosing clearings in the woods since the Early Bronze Age, which gradually expanded during the Middle Bronze Age. Furthermore, several charcoals from a Middle Bronze Age hearth seem to be of the same age, and the pattern of their annual growth-rings suggests the pollarding of broadleaved trees.
