We analysed the late-Holocene pedo-sedimentary archives of La Narse de la Sauvetat, a hydromorphic depression in the southern Limagne plain (central France), where chronologically accurate studies are scarce. The multi-proxy geoarchaeological and palaeoenvironmental analysis of two cores from different areas of the basin was carried out through sedimentological, geochemical, micromorphological and malacological investigations. Integration of these datasets supported by a robust radiocarbon-based chronology allowed discussion of socio-environmental interactions and anthropogenic impacts from Late Neolithic to Early Middle Ages. Until the Middle Bronze Age, there was no clear evidence of anthropogenic impact on soils and hydro-sedimentary dynamics of the catchment, but two peaks of high alluvial activity probably related to the 4.2 and 3.5 kyr. BP climate events were first recorded in Limagne. Significant anthropogenic impacts started in the Late Bronze Age with increased erosion of the surrounding volcanic slopes. However, a major threshold was reached c. 2600 cal BP with a sharp increase in the catchment erosion interpreted as resulting from strong anthropogenic environmental changes related to agricultural activities and drainage. This implies an anthropogenic forcing on soils and hydro-sedimentary systems much earlier than was usually considered in Limagne. These impacts then gradually increased during Late Iron Age and Roman periods, but environmental effects were certainly contained by progress in agricultural management. Late Antiquity environmental changes are consistent with regional trend to drainage deterioration in lowlands, but marked asynchrony in this landscape change suggests that societal factors implying differential land management were certainly predominant here.

We review the reasons for change in paleoecological conditions and their effects on different cultures at the beginning and during the Holocene period in western Hungary using radiocarbon data combined with paleoecological and paleolimnological results. Two sites were investigated in the southern and northern part of the ancient bay of Balaton Lake: Keszthely-Úsztatómajor and Főnyed I. 14C dating of 2 core samples represented a chronology from 11,000 cal BC to 2000 cal BC (10,700 BP to 3700 BP) and from 6200 cal BC to 1200 cal BC (7300 BP to 3000 BP), respectively. A relatively constant inverse sediment accumulation rate was observed in both cases (23 yr/cm and 33 yr/cm, respectively). In the case of Főnyed I, a sharp break was observed in the sedimentation curve around 6000–4800 cal BC (6000 BP). Changes in the vegetation due to human activity were observed in a larger extent only at the end of Late Neolithic, with the most significant changes detected in the landscape coinciding with the presence of Lengyel III culture in the region. The appearance of higher amounts of pollen of cereals at the sites proved the presence of crop cultivation. However, the role of plant cultivation may have been limited for the ancient inhabitants of the Kis-Balaton region due to a limited amount of soil suitable for agriculture and due to the extensive water table. Further changes in vegetation were observed during the Late Copper Age (Baden culture) and the period of Early and Middle Bronze Age, respectively. Signs of forest clearing during the period have not been detected and the increased peak of Fagus indicates climatic change. The low intensity of anthropogenic activity should not be attributed to geographic isolation.

The Early Iron Age enclosures and associated sites on Sutton Common on the western edge of the Humberhead Levels contain an exceptional variety of archaeological data of importance not only to the region but for the study of later prehistory in the British Isles. Few other later prehistoric British sites outside the East Anglian fens and the Somerset Levels have thus far produced the quantity and quality of organically preserved archaeological materials that have been found, despite the small scale of the investigations to date. The excavations have provided an opportunity to integrate a variety of environmental analyses, of wood, pollen, beetles, waterlogged and carbonised plant remains, and of soil micromorphology, to address archaeological questions about the character, use, and environment of this Early Iron Age marsh fort. The site is comprised of a timber palisaded enclosure and a succeeding multivallate enclosure linked to a smaller enclosure by a timber alignment across a palaeochannel, with associated finds ranging in date from the Middle Bronze Age to the Roman and medieval periods. Among the four adjacent archaeological sites is an Early Mesolithic occupation site, also with organic preservation, and there is a Late Neolithic site beneath the large enclosure. Desiccation throughout the common is leading to the damage and loss of wooden and organic remains. It is hoped that the publication of these results, of investigations between 1987 and 1993, will lead to a fuller investigation taking place.

It is 50 years since Stuart Piggott excavated the prehistoric complex at Cairnpapple. At that time there were few excavated parallels in Scotland, and interpretation inevitably relied heavily on sites excavated in southern Britain. Much more locally relevant data are now available and the sequence at Cairnpapple can now be reassessed its regional context.Piggott identified five Periods, commencing with a stone setting, ‘cove’ and cremation cemetery of ‘Late Neolithic date’ around ‘c. 2500 B.C.’. Period II was a henge monument, consisting of a ‘circle’ of standing stones with ceremonial burials in association, and an encircling ditch with external bank – ‘Of Beaker date, probably c. 1700 B.C.’ Period III comprised the primary cairn, containing two cist-burials ‘Of Middle Bronze Age date, probably c. 1500 B.C.’ Period IV involved the doubling of the size of the cairn, with two cremated burials in inverted cinerary urns. ‘Of final Middle Bronze Age or native Late Bronze Age date, probably c. 1000 B.C.’ Period V comprised four graves ‘possibly Early Iron Age within the first couple of centuries A.D.’The present paper, using comparable material from elsewhere in Scotland, argues for a revised phasing: Phase 1, comprises the deposition of earlier Neolithic plain bowl sherds and axehead fragments with a series of hearths. This is comparable to ‘structured deposition’ noted on other sites of this period. Phase 2 involved the construction of the henge – a setting of 24 uprights – probably of timber rather than stone, probably followed by the encircling henge ditch and bank. The ‘cove’ is discussed in the context of comparable features in Scotland. Phase 3 saw the construction of a series of graves, including the monumental ‘North Grave’, which was probably encased in a cairn. Piggott's ‘Period III’ cairn was then built, followed by the ‘Period IV’ cairn. The urn burials seem likely to have been inserted into the surface of this mound, which may have covered a burial (since disturbed) on the top of the Period III mound, or may have been a deliberate monumentalising of it. The four graves identified as Iron Age by Piggott seem more likely to be from the early Christian period.The reassessment of Piggott's report emphasises the value of the writing of a clear, and sufficiently detailed account. While no report can be wholly objective it can be seen that Piggott's striving for objectivity led him to write a paper that is of lasting value.

AbstractThe significance of geoarchaeological investigations is indisputable in reconstructing the former environment and in studying the relationship between humans and their surroundings. Several disciplines have developed during the last few decades to give insight into earlier time periods and their climatic conditions (e.g. palynology, malacology, archaeobotany, phytology and animal osteology). Charcoal and pollen analytical studies from the rescue excavation of the MO motorway provide information about the vegetation changes of the past. These methods are used to reconstruct the environment of the former settlements and to detect the human impact and natural climatic changes. The sites examined span the periods of the Late-Copper Age, Late-Bronze Age, Middle-Iron Age, Late-Iron Age, Sarmatian period, Late Sarmatian period, Migration period, Late-Migration period and Middle Ages. The vegetation before the Copper Age is based only on pollen analytical data. Anthracological results show the overall dominance of Quercus and a great number of Ulmus, Fraxinus, Acer, Fagus, Alnus and Populus/Salix tree fossils, as well as the residues of fruit trees present in the charred wood assemblage.

Archaeologists tend to use typochronological frameworks to date their sites. These are based on the appearance of certain cultural markers such as grave types or houseplans. In the Meuse-Demer-Scheldt region, a chronological framework is used for the cremation cemeteries from the Middle Bronze Age until the Late Iron Age based on the size, number, and presence of different types of cremation graves. Radiocarbon dating of cremated bone from the small cemetery at Lummen-Meldert dates this site to the Late Bronze Age. These results challenge the hypothesis that small cremation cemeteries with mostly “unurned” graves date to the Middle Iron Age. The cremation graves without an urn and grave goods are a specific category that has to be dated by absolute dating methods such as14C. The results also suggest a connection with the funerary traditions in the Atlantic region.

AbstractIn the area of archaeological excavations that were performed prior to the construction of Main Road No. 86 in Vas County (West Hungary) in the Alpine foreland new geoarchaeological analyses have been conducted. We used anthracology and pollen analyses to reconstruct the former vegetation cover at the study site. Charcoal data provide site-related information about the local woodland composition, management and human impact, while pollen data provide information on the arboreal and non-arboreal vegetation on a regional or local scale. Adequate samples for anthracological analyses derive from the Bronze Age, Iron Age, Imperial and Migration Periods and Middle-Ages archaeological objects. The core for pollen analyses originates from alluvial sediments of the Borzó Creek and covers the late Pleistocene and the Holocene until the Medieval Period. Charcoal analyses show the dominance of Quercus trees in the vicinity of the human settlements that might indicate a strong human selection, or the fragmentation of samples. Pollen analyses indicate thermophilous vegetation from the beginning of the Holocene, with increasing values of Fagus and Carpinus. Pollens of cereals indicate human activity, which is also demonstrated by the presence of pollen from Juglans and Vitis in the Iron Age sequence. Extensive forest clearance occurred in the Late Iron Age and the Imperial Period.

The aim of this paper is to question the supposed isolated and backward position of the region of Westerwolde, in the north-eastern part of the Netherlands. Westerwolde’s geographically rather isolated position has traditionally been brought forward to explain its backward image. Progressive peat growth ever since the Bronze Age occupation had transformed Westerwolde into an island. It was abandoned in the Late Iron Age, only to be recolonized in the early Middle Ages. During the 19th century, romantics were still admiring Westerwolde’s arcadian scenery and cultural traditions. In contrast, from the mid-19th century until well into the 20th century, protagonists of modern agriculture criticized its backward farming methods and standard of living, as well as its poor infrastructure. The central issues we address here is whether critics were justified in describing it as backward in the 19th century and whether concrete indications for this assumed backwardness are to be found in previous centuries. To jump from early medieval times to the 19th century is too big a leap, but combining archaeological and ecological data with a renewed and more critical study of written sources against the background of huge landscape transformations has brought a nuanced understanding of how Westerwolde evolved. We present new insights for the period starting with the conquest of Frisia and Saxony by the Carolingians and the introduction of Christianity, when missionaries and newly founded monasteries acquired agricultural assets and rights in the conquered region, up to the late Middle Ages. We therefore analyze church foundations, livelihoods or economic conditions of existence in connection with occupation structures, infrastructure and exchange of consumer goods interdisciplinarily. Conservatism appears easily confused with backwardness, and an aversion to innovation, with indifference, as underlying external factors often forced the inhabitants to adopt a wait-and-see attitude. Westerwolde is viewed continuously in connection with the adjacent regions of Drenthe and Lower Saxon Emsland.

In this study, the orientations of c. 138 long cairns located in coastal Finland were measured and examined, along with other properties of the cairns. The length of the cairns varies from a few metres to almost 50 m. The dominant color of the stones in most of the cairns is red, and they were usually built on locally elevated terrain, e.g. on ridges, rocky outcrops or small islets on the ancient shore. It was found that in the category of long cairns there were several different types of elongated cairns: the ‘simple’ and curved long cairns, some of which were attached to round cairns; the rectangular cairns with one or more central chambers; the very large rectangular cairns; and two different types of ship-formed cairns, Type 1 and Type 2, the latter of which was a previously an unrecognised type of Late Neolithic/Early Bronze Age long cairn. The comparison of the orientations of the cairns of different types and locations suggest that there was some cultural continuity between the Neolithic and the Early Bronze Age cultures on the western coast of Finland. However, based on the present analysis, this continuity does not seem to have extended beyond the Middle Bronze Age. It is also suggested that the appearance of the Type 2 ship-formed cairn in the Ostrobothnia region in the Late Neolithic may have resulted from outside cultural influences, perhaps from the earliest contacts with the central ideologies of the Nordic Bronze Age.

In this article we describe the evaluation of two prehistoric sites situated within the coastal zone of south-western Albania, originally investigated by the Italian prehistorian Luigi Cardini in 1939. The first is a cave site in the town of Himara; the second a rock-shelter at Kanalit in the Acroceraunian Mountains to the north. Investigations at both locations revealed stratified evidence of prehistoric activity dating from the mid-Holocene. At Kanalit, an extensive lithic assemblage provided evidence for the exploitation of the adjoining coastal lowlands during the Mesolithic, while at Himara, a largely unbroken sequence of deposits records often intensive human activity at the cave from the Early Bronze Age. Radiocarbon dates have provided a significant independent chronological marker for Early/Middle Bronze Age horizons. The ceramic evidence indicates a predominance of local influences, the site not becoming part of wider trading networks until the late Iron Age, c. seventh to sixth centuries BC.Σε αυτό το άρθρο πραγματευόμαστε τη σημασία δύο προϊστορικών θέσεων, οι οποίες βρίσκονται στην παράκτια ζώνη της ΝΔ Αλβανίας. Οι θέσεις αυτές είχαν αρχικά ερευνητεί από τον Ιταλό προϊστορικό αρχαιολόγο Luigi Cardini το 1939. Η πρώτη θέση αφορά ένα σπήλαιο στην πόλη της Χειμάρρας και η δεύτερη μία βραχοσκεπή, στη θέση Kanalit, στα Ακροκεραύνια όρη προς βορρά. Έρευνες στις δύο θέσενς αποκάλυψαν στρωματογραφημένες ενδείξεις προϊστορικής δραστηριότητας, που χρονολογούνται από το μέσο Ολόκαινο. Στη θέση Kanalit ένα ευρύ σύνολο λίθινων αντικειμένων παρέχει στοιχεία για την εκμετάλλευση των γειτονικών παράκτιων πεδινών περιοχών κατά τη Μεσολιτική περίοδο. Στο σπήλαιο της Χειμάρρας μία σειρά από αδιάσπαστες, στο μεγαλύτερο μέρος τους, αποθέσεις μαρτυρεί συχνά έντονη ανθρώπινη δραστηριότητα από την Πρώιμη Εποχή του Χαλκού. Οι ραδιοχρονολογήσεις παρέχουν ένα σημαντικό ανεξάρτητο χρονολογικό δείκτη για τους ορίζοντες της Πρώιμης/Μέσης Εποχής του Χαλκού. Η κεραμική φανερώνει την επικράτηση τοπικών επιρροών, με τη θέση αυτή να μην λαμβάνεν μέρος στα ευρύτερα εμπορικά δίκτυα πριν από την όψιμη Εποχή του Σιδήρου, περίπου τον 70 – 60 αιώνα π.Χ.
