The softstone vessels from ed-Dur, Umm al-Qaiwain, United Arab Emirates

Sixty-two softstone vessels found at the coastal site of ed-Dur, Umm al-Qaiwain (U.A.E.), less than 1% of the total amount of artefacts registered at the site, are examined for evidence of (inter)regional exchange. Emphasis is laid on the vessels from the PIR C phase. In recent research much attention has been paid to the spatial distribution and trade of softstone vessels of earlier times. An attempt will be made to do the same for the dark grey softstone vessels dating ca . 300 BC–300 AD.     

The softstone vessels from Qarn Bint Sa'ud, Abu Dhabi (U.A.E.)

This paper draws attention to thirty unpublished Iron Age softstone vessels from Qarn Bint Sa'ud held in the Al Ain Museum. They are compared with softstone vessels from other Iron Age sites in the United Arab Emirates, Bahrain, Oman and Mesopotamia, in order to study distribution patterns and exchange.     

A 'Hut pot'in the National Museum, Bahrain

This note presents a fine softstone vessel which has not previously been fully published. Its findspot supports the recent suggestion that such pots continued to be manufactured until the end of the third millennium.     

Roman Glazed Ceramics in the Western Mediterranean: Chemical Characterization by Inductively Coupled Plasma Atomic Emission Spectrometry of Ceramic Bodies

Several objects of Roman lead-glazed ceramic, found inHispania(Spain), were sampled and analysed in order to characterize them to study the spread of glazed ceramic in the western Mediterranean. Chemical analyses were carried out by Inductively Coupled Plasma Atomic Emission Spectrometry.Studies of the chemical composition of the ceramic bodies indicate that ceramics from two different production centres reachedHispaniaduring the Roman period: a non-calcareous fabric, coming from Lyon workshops, and calcareous bodies with bicoloured glazes from another main production centre, which is suggested to be Italy. Other objects, of central Gaulish or eastern origin, have also been found in the western Mediterranean, but only occasionally.     

Croatian Appoxiomenos alloy composition and lead provenance study

An ancient bronze statue of an athlete with a strigil (known as Apoxiomenos) – was raised from the north Adriatic Sea in 1999. In order to help to determine its place and date of manufacture various scientific techniques were used. ¹⁴C dating performed by the Accelerator Mass Spectrometry (AMS) on the organic material found inside the statue gave calibrated dates between 100 B.C. and 250 A.D. Non-destructive analysis performed by portable X-Ray Fluorescence (XRF) system and external beam Particle Induced X-Ray Emission (PIXE) spectroscopy could not provide representative results for metal alloy composition due to the electrochemical deterioration of the surface of bronze in seawater. This was observed by the analysis of alloy cross-sections performed by the proton microprobe. The analysis showed much higher lead concentrations on the surface of the bronze than inside, confirming that realistic alloy composition can be only performed on samples taken from at least 0.6 mm below the surface. Subsequent micro-PIXE analysis on metal cross-section showed inhomogeneous lead concentrations between 1 and 12%. Lead isotope analysis for provenance investigation has been done on 15 samples using Multi Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS). Analysis showed that lead isotope composition is consistent with some of the lead ores originating either from the Eastern Alps or from Sardinia. Altogether, the results lead to the conclusion that the statue is not of a Greek origin, but most probable it is a Roman copy of the Greek original.     

Pigments from the Middle Palaeolithic levels of Es-Skhul (Mount Carmel,Israel)

Discovery of pigments at Middle Palaeolithic sites is of interest in the context of the ongoing debate about the tempo and mode of the emergence of modern human behaviour. Here we analyse four previously undescribed fragments of pigmental material from Es-Skhul shelter, layer B, Israel, McCown excavations, identified at the Department of Palaeontology, Natural History Museum, London. One of them is still partially embedded in the hard breccia characteristic of this layer. Inspection of breccia fragments from layer B has led to the identification of small pieces of red and orange pigmental material still enclosed in large clasts, further corroborating the attribution of the larger pieces analysed in this study to layer B. The four objects are studied using optical microscopy, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray (EDX), X-ray micro-diffraction (μ-XRD), Particle-Induced X-Ray Emission Spectrometry (PIXE), and Proton-Induced Gamma-ray Emission (PIGE). The specimens display various hues of yellow, orange, red, and one of them presents a gradual variation of shade from yellow to dark orange. SEM/EDX analysis identifies two specimens (Skhul 1 and 2) as being composed of iron-rich calcium phosphate, the third (Skhul 3) of potassium-rich clay with titanium-rich iron oxide inclusions, and the fourth (Skhul 4) of pure iron oxide crystals. TEM/EDX and μ-XRD analysis demonstrate that three pieces (Skhul 1, 2 and 4) were heated to at least 300 °C, a process that has partially or completely dehydrated goethite into haematite and changed their pristine yellow colour into orange or red. Skhul 3 shows no sign of heating, suggesting that its haematite content has a geological origin. The different mineral composition of the pieces suggests that they must come from a variety of sources. This implies that the associated collection strategies included the selection of materials that differed not only with respect to colour but also with respect to other physical and chemical properties. Although no formal proof exists that these lumps of pigmental material were deliberately heated, results obtained are consistent with this explanation.     

Provenance of Zhangzhou export blue-and-white and its clay source

Trace element compositions of 25 shards of Chinese Late Ming export blue-and-white porcelain from Zhangzhou and Jingdezhen kilns are analysed by Inductively Coupled Plasma Mass Spectrometry. Principle components analysis and REE distribution curves are used to establish method for provenance unknown Chinese export blue-and-white porcelain which may have originated from Zhangzhou or Jingdezhen kilns. By matching the REE distribution curves of Zhangzhou kiln samples and parent rocks of the possible clay sources used to make Zhangzhou blue-and-white, and comparing it with previous results of geological, geochemical and archaeological researches, the clay used for producing Zhangzhou export blue-and-white has been identified as having been collected from the weathered shells of a nearby potassium feldspar miarolitic granite outcrop.     

Computer programmes for the correction of matrix effects in the XRF analysis of glass,ceramics and related silicate systems

The quantitative analysis of glass, ceramics and related silicate systems by means of energy dispersive X-ray fluorescence spectrometry is considered and problems arising from the selective absorption of X-rays in multi-element specimens are discussed. A computer programme written in FORTRAN and based upon a “semi-fundamental parameters” approach to the correction of matrix effects in glass and chemically similar materials is fully described. Model data are provided to enable the programme to be run and tested. An “empirical coefficients” computer programme for the quantitative analysis of silicate systems is outlined and the limitations of this type of programme are pointed out. The importance of adequate sample preparation prior to X-ray spectrometric analysis is stressed.     

Geochemical characterisation of north Asian glazed stonewares: a comparative analysis of NAA,ICP-OES and non-destructive pXRF

The analytical performance of non-destructive portable X-ray fluorescence (pXRF) is compared with that of Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Neutron Activation Analysis (NAA) for the elemental characterisation of a group of glazed stonewares from North-East Asia. As a non-destructive technique pXRF is potentially well suited to the elemental analysis of high value archaeological and museum collections but has yet to be critically evaluated for the analysis of archaeological stonewares. In this study we use multivariate evaluation to compare results from non-destructive pXRF in relation to ICP-OES and NAA analysis for the same group of samples. We conclude that, although pXRF is comparatively limited to a small number of major, minor and trace elements, these are sufficient to identify the same compositional groups as high dimensional ICP-OES and NAA datasets for this assemblage.     

Viking woollen square-sails and fabric cover factor

The discovery of the five scuttled Viking ships of Roskilde Fjord in Denmark and the subsequent excavation, preservation and analysis of the remains has initiated a programme of reconstructive archaeology led by the Viking Ship Museum of Roskilde in which four of the five hulls have now been reconstructed together with their rigs and square-sails. The reconstruction of the sails has been based on fragments of heavy woollen cloth found within the roof of Trondenes church in Norway dating to the mid-13th century. This paper uses the'cover-factor' modelling methods of modern textile engineering to analyse the'Viking' sail fabrics and assess their strength, resilience and performance in comparison with the linen sails from the wreck of the Vasa .     

SCIENTIFIC ANALYSIS OF ROMAN GLASS FROM AUGUSTA PRAETORIA

Fifty-five fragments of Roman glass from Augusta Praetoria (Aosta, Italy) were analysed by inductively coupled plasma optical emission spectroscopy determining 15 elements (Si, Na, Ca, Al, Fe, Mg, Mn, Ti, Sr, Ba, Cr, Ni, Cu, Co and Pb) on dissolved samples; in addition, potassium was determined by flame atomic absorption spectroscopy. The analytical results indicate that all the fragments, with one exception, are silica-soda-lime glasses; (he exception is a potash glass. Cluster analysis was performed on the analytical data by accounting for either 14 (all the elements searched for but Ni and Pb) or eight elements (after further removal of Si, Fe, Mn, Cr, Cu and Co from the data set). The results obtained indicate that, once colouring and decolouring agents are removed, the classification of the glasses seems to be mainly determined by chronology; separate groups within coeval fragments may indicate different provenances.     

The Use of Multiple Correspondence Analysis (MCA) in Taphonomy: The Case of Middle Helladic Asine,Greece

The goal of this paper is to investigate whether multiple correspondence analysis (MCA), a multivariate statistical technique, is a useful dimensionality‐reduction tool in zooarchaeological and taphonomic studies. For this purpose, the focus is to detect and discuss traces of waste management. Animal bones from waste‐related contexts at the Bronze Age site Asine, Greece, are investigated. The data consist of bone fragments dating to the Middle Helladic from this site. Unidentified fragments were categorised in size classes, where possible. Information on taxa, skeletal parts and the presence or absence of several taphonomic markers is included in the data set. The MCA reveals several correlations of zooarchaeological interest. For example, the association between indeterminate fragments and calcined bone points to issues concerning identification and preservation. Floors are characterised by weathered long‐bone fragments from medium‐sized mammals. Additionally, the results of MCA indicate that the material might have suffered from density‐mediated attrition, based on the abundance of axial fragments, which did not differ between different contexts and taxa. The results show that MCA can be used to detect zooarchaeological and taphonomic patterns. This multivariate technique is useful when investigating large data sets, as is often the case with large zooarchaeological assemblages. Copyright © 2016 John Wiley & Sons, Ltd.     

Non-ferrous metallurgy from the Phoenician site of La Fonteta (Alicante, Spain): a study of provenance

The lead isotope composition of 22 samples from the excavation of the Phoenician site of La Fonteta (Guardamar del Segura, Alicante, Spain) has been analysed in a preliminary study of their provenance. These materials span chronologically from the first half of the 8th century BC to the middle of the 6th century BC.The samples have been selected to include materials used in lead and silver production, as well as in copper-based metallurgy. Therefore, lead droplets, galena nodules and fragments of litharge have been analysed, together with a fragment of a copper ingot, an object, a melting waste composed of a Cu–Pb alloy, and two fragments of a material that we have provisionally labelled ‘Pb–Cu cupellation debris’.All these materials have been initially analysed by X-Ray Fluorescence-Spectrometry to identify their bulk compositions. Some of them have been also analysed by SEM–EDX and ICP–OES. Subsequently, lead isotope analyses (LIA) have been performed using Thermal Ionization Mass Spectrometry (TIMS). The new LIA data obtained has been compared with published lead isotope data from the Mediterranean area. The identification of different groups suggests a significant complexity of the internal and external trade routes during the Orientalising period. For this reason, the provenance study of these materials is especially important in shedding light on the commercial dynamics that the Phoenicians established with native people to control the raw materials and to commercialise finished products.     

In/visible: the inside story of the making of Arts at CERN

ABSTRACT

This is a personal account of the setting up and first five years of CERN's first institutionalized arts programme, in which artists from different art forms were invited to engage with scientists with no requirements for any outputs. The focus instead was on the creative process, the exchanges between the artists and scientists and their shared knowledge-making. Paradoxically, given this freedom, even by the end of the initial phase of the programme they had produced a range of artworks and performances, some of which were to go on to attract international acclaim. The paper identifies some of the key issues and challenges faced when undertaking an arts programme within a science institution. These issues are rarely openly discussed and written about, yet they are vital for shared cultural learning in this rapidly evolving and increasingly popular field.     

Fish ’n chips: ZooMS peptide mass fingerprinting in a 96 well plate format to identify fish bone fragments

Fish are a large, highly diverse, and anthropologically important group of vertebrates. However, fish bones are underrepresented in the archaeological literature because they are less stable than those of other taxa and identification of bone to species is often difficult or impossible. We explore a new identification system, ZooMS (Zooarchaeology by Mass Spectrometry), which is based upon protein barcoding. As proteins can be cleaved enzymatically and analyzed by mass spectrometry in a repeatable way, protein barcoding is used widely in microbiological contexts for quick and inexpensive protein identification; mass spectra reflect the differences in protein sequence and can therefore be reproducibly linked to a particular protein or protein fragment. ZooMS uses peptide fingerprinting of bone collagen as a method for rapid identification of archaeological bone. This has involved the identification of masses related to peptides of known sequence. For mammals, sufficient sequence information is available for this approach but for groups, such the teleost fish, species are highly diverse and there are few available collagen sequences. Here we report a preliminary investigation into the identification of fish species by peptide mass fingerprinting that does not require sequence information. Collagen mass spectra are used to identify eight species of bony fishes (Osteichthyes) from four orders: Clupeiformes, Salmoniformes, Gadiformes, and Perciformes. The method is applied to both modern and archaeological fish remains and offers the capacity to identify traditionally unidentifiable fish fragments, thus increasing the Number of Identified Specimens (NISP) and providing invaluable information in specialized contexts.     

A pilot compositional analysis of Nasca ceramics from the Kroeber collection

In this paper we report on Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) of a sample of ceramics from Nasca, Peru collected by Alfred Kroeber in the 1920’s and curated at the Field Museum of Natural History in Chicago. The analysis was conducted for two principal reasons: (1) to test the efficacy of LA-ICP-MS when compared to INAA; and (2) to evaluate samples that post-date Early Nasca (where focus has primarily been placed). We show here that LA-ICP-MS is a viable alternative to INAA, present some of the compositional variability in the Kroeber samples, and propose some explanations for this variability.     

The Block of Tin Dredged up in Falmouth Harbour,and now in the Truro Museum

A campaign of excavations in advance of development in Greater London during the 1970s and 1980s has led to a major programme of post-excavation analysis and publication of the results. The background to this programme reflects the way in which archaeology in Britain has developed since the 1970s. A highly structured approach has been adopted to the programme, involving a series of stages and careful selection of material for detailed analysis and publication. Some twenty-five monographs and nineteen major articles will result from the work, covering prehistoric, Roman, Saxon, medieval, and post-medieval topics across Greater London. Prehistoric landscapes in West London, Roman Southwark, the Middle Saxon emporium of Lundenwic, medieval religious houses, and post-medieval industries in Southwark will be particular foci of attention. In addition, an archive guide giving summary details of all the excavations undertaken will be produced. The programme will make a substantial contribution to our knowledge of the archaeology of Greater London.     

TOWARDS AN UNDERSTANDING OF SPATIO‐TEMPORAL DYNAMICS AT GREAT ZIMBABWE: CONTRIBUTIONS OF THE URBAN ORIGINS IN EASTERN AND SOUTHERN AFRICA PROGRAMME

In 1987 archaeologists from nine African countries and colleagues from Sweden began a co‐operation programme to study urbanism in eastern and southern Africa under the auspices of The Urban Origins programme. The programme involved 22 parallel field projects throughout the West Indian Ocean region and the southern Africa interior. The article presents a compilation of diverse material on Great Zimbabwe that has been scattered in different fora. The research was directed by an overall approach that investigations in urban archaeology in Africa must be at the same scale that people lived in the past. The results briefly presented here show the potential of multivariate assessments of the spatial distributions of large‐scale urban sites in Africa.     

Roman lead mining in Germany: its origin and development through time deduced from lead isotope provenance studies

High precision lead isotope analysis by Multi Collector Inductively Coupled Plasma Mass Spectrometry was applied to the investigation of more than 240 Roman lead objects from several archaeological sites in Germany, in order to obtain information on the pattern of Roman mining activity and ore processing in the area. Measurements of ore samples from German deposits east (Siegerland, Lahn-Dill, Ems) and west of the Rhine (Eifel, Hunsrueck) were made and supplemented with data from literature to create a data bank of lead isotope ratios of European lead occurrences. Comparing the isotope ratios of lead objects with those from German ore deposits shows that the source of over 85% of the objects is Eifel ore deposits, but that, in the early years, the Romans also imported lead from the Southern Massif Central and later from Britain.
