1989: THE CHRONOPOLITICS OF REVOLUTION

A failed effort at “reform from above” or a dramatic reassertion of “people power”? Almost thirty-five years on, studies of the Revolutions of 1989 continue to be framed by these two polarities. However, this historiographical focus has meant that scholars have often overlooked the actual content and character of protest itself. This article argues that one way of reinjecting agency and ideas back into our historical understanding of 1989 is through examining the chronopolitics of revolution: that is to say, by addressing how the control and interpretation of time became a political battlefield, a site of contention and negotiation, between Communist regimes, on the one hand, and political activists and society, on the other. Investigating events in the German Democratic Republic and Czechoslovakia, the article contains two central claims: first, that an interrogation of the concept of “chronopolitics” can provide a new angle by which to grasp the revolutionary character of “1989” and the democratic transformations that resulted and, second, by way of inversion, that a study of the temporal experiences across 1989 and the early 1990s can in turn shed light on the analytical value of “chronopolitics” more generally.     

Land Snail Shell Beads in the Sub-Saharan Archaeological Record: When,Where, and Why?

Shell beads are well established in the archaeological record of sub-Saharan Africa and appear as early as 75,000 BP; however, most research has focused on ostrich eggshell (OES) and various marine mollusc species. Beads made from various land snails shells (LSS), frequently described as Achatina, also appear to be widespread. Yet tracking their appearance and distribution is difficult because LSS beads are often intentionally or unintentionally lumped with OES beads, there are no directly dated examples, and bead reporting in general is highly variable in the archaeological literature. Nevertheless, Achatina and other potential cases of LSS beads are present at over 80 archaeological sites in at least eight countries, spanning the early Holocene to recent past. Here, we collate published cases and report on several more. We also present a new case from Magubike Rockshelter in southern Tanzania with the first directly dated LSS beads, which we use to illustrate methods for identifying LSS as a raw material. Despite the long history of OES bead production on the continent and the abundance of land snails available throughout the Pleistocene, LSS beads appear only in the late Holocene and are almost exclusively found in Iron Age contexts. We consider possible explanations for the late adoption of land snails as a raw material for beadmaking within the larger context of environmental, economic, and social processes in Holocene Africa. By highlighting the existence of these artifacts, we hope to facilitate more in-depth research on the timing, production, and distribution of LSS beads in African prehistory.     

CHARACTERIZING THE EVOLUTION OF VISUAL LANDSCAPES IN THE LATE PREHISTORY OF SOUTH-WEST MORBIHAN (BRITTANY, FRANCE)

Summary.   In the context of territorial analyses in archaeology, the visual attributes of sites play a key role in the definition of location strategies. This paper studies the Neolithic evidence from the south-western Morbihan area in Brittany (France) from a visual point of view, integrating the previous Mesolithic and the later Bronze Age occupation of the region in order to understand the diachronic evolution of the visual settlement patterns. The role played by the sea seems to be significant throughout the entire occupation of the area, but differences in both intervisibility of sites and the extension of visual areas allow us to make particular observations regarding different cultural uses of the landscape through time.     

Sustainability Science Partnerships in Concept and in Practice: a Guide to a New Curriculum from a European Perspective

This paper makes the case for advancing sustainability science partnerships (SSPs) both within universities and through innovative means of integrating universities with external public‐private and civil sectors. It links the basic principles of sustainable development with an emerging science of cooperative learning that connects researchers to a wide range of partners. SSPs are specifically designed to be transformational through becoming active agents for societal change. Universities play a special role here because they can act both as communication networks and as laboratories for developing the capability to design and manage SSPs in the creative transition to sustainability. It is gratifying to note that these ideas are beginning to emerge in a number of universities, with European examples being highlighted in this paper. Further steps towards introducing full‐blooded SSPs across the university spectrum are suggested.     

DNA FROM HUMAN ANCIENT BACTERIA: A NOVEL SOURCE OF GENETIC EVIDENCE FROM ARCHAEOLOGICAL DENTAL CALCULUS

We report a molecular methodology to obtain and analyse ancient bacterial DNA from archaeological dental calculus. Recent and archaeological DNA samples, as old as 4000 bp , were successfully extracted and amplified with species‐specific PCR primers. We propose this approach in order to: detect the presence of specific bacterial species infecting past human populations; compare the composition of ancient oral microbiomes among human populations; and analyse the genetic variability and covariation of bacteria and human host populations. Genomic analysis of bacteria from dental calculus is a promising source of evidence for palaeopathological and micro‐evolutionary studies, focused either on micro‐organisms or their human hosts.     

CHARACTERIZATION AND THERMOLUMINESCENCE DATING OF PREHISTORIC POTTERY SHERDS FROM MILENA

This paper reports the results obtained applying absolute dating methodologies and mineralogical, petrographical and micropalaeontological characterization techniques to prehistoric pottery sherds varying in age from the Sicilian Middle Neolithic to Bronze Age. All samples came from the archaeological area of Milena (Caltanissetta, Sicily); those of the Bronze Age were found on a site with a precise stratigraphic succession. The investigation has contributed to the determination of an absolute chronology for the Milena prehistoric period. The data provide, for the first time in Sicily, absolute dates covering a wide spectrum of cultures following one another in the same area and, for the Bronze Age site, correlated to the precise stratigraphic succession. The petrographical and mineralogical analyses allowed not only the identification of the principal constituents of the pottery, but also the formulation of some hypotheses regarding the specific manufacturing techniques of different epochs. The microfacies, obtained from the presence of fossils in the groundmass of the pottery, were also analysed and compared with the microfauna present in the Miocene clays outcropping in the area. The data identified local Messinian clay as the raw material probably used in the manufacture of the pottery and also support the presence, already assumed by archaeologists, of imported Mycenaean pottery, thus supporting the dates obtained on pottery taken from the same stratum.     

A NEW DATE FOR THE NEANDERTHALS FROM EL SIDRÓN CAVE (ASTURIAS,NORTHERN SPAIN)*

Torres et al. (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA‐21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre‐treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.     

TIME‐OF‐FLIGHT NEUTRON DIFFRACTION CHARACTERIZATION OF CERAMIC FINDINGS FROM SOUTHERN AND WESTERN SICILY*

We present the results of a study that is part of a wider research programme regarding knowledge of the initial living phases of Sicilian agricultural and pastoral society. Three sets of ceramic samples were analysed through time‐of‐flight neutron diffraction (TOF‐ND) to derive information about the composition of the clay and the manufacturing techniques. The first two sets of sherds came from an excavation in Licata, close to Agrigento, and are composed of findings dated around the third century bc , while the third set was of samples from prehistoric sites located in the northwestern part of Sicily. Measurements were performed to obtain a quantitative identification of the mineralogical composition of the samples in a totally non‐destructive way. Hints about manufacturing techniques and firing temperatures are derived to provide information on provenance and production processes of the objects.     

Excavations at Mlambalasi Rockshelter: a Terminal Pleistocene to Recent Iron Age Record in Southern Tanzania

The Mlambalasi rockshelter in the Iringa Region of southern Tanzania has rich artifactual deposits spanning the Later Stone Age (LSA), Iron Age, and historic periods. Middle Stone Age (MSA) artifacts are also present on the slope in front of the rockshelter. Extensive, systematic excavations in 2006 and 2010 by members of the Iringa Region Archaeological Project (IRAP) illustrate a complex picture of repeated occupations and reuse of the rockshelter during an important time in human history. Direct dates on Achatina shell and ostrich eggshell (OES) beads suggest that the earliest occupation levels excavated at Mlambalasi, which are associated with human burials, are terminal Pleistocene in age. This is exceptional given the rarity of archaeological sites, particularly those with human remains and other preserved organic material, from subtropical Africa between 200,000 and 10,000 years before present. This paper reports on the excavations to date and analysis of artifactual finds from the site. The emerging picture is one of varied, ephemeral use over millennia as diverse human groups were repeatedly attracted to this fixed feature on the landscape.     

THE TECHNOLOGICAL AND TYPOLOGICAL BEHAVIOUR OF A NEANDERTHAL GROUP FROM EL SIDRÓN CAVE (ASTURIAS,SPAIN)

This paper presents the first detailed analysis of the lithic industry from El Sidrón Cave. Previously we have published other works concerning Anthropology and Palaeogenetics. The lithic assemblage contains 415 artefacts coming from both unofficial and official excavations and is largely flake‐based. The raw material derives from the immediate cave environment, and is mostly chert, with quartzite in a lesser proportion. To date, 67 artefacts have been refitted, including some tools and cores. The spatial distribution of the refitted lithic artefacts confirms, on the one hand, the unity of the assemblage and, on the other, its secondary context.
