  • Geochemical and Petrographic Analysis of Late Bronze Age Cypriot Ceramics
           (White Slip I and II and Monochrome) from Tell Atchana/Alalakh (Hatay) in
           the Amuq Valley
    • Authors: S. Hacıosmanoğlu; M. Kİbaroğlu, G. Sunal, E. Kozal, P. Gutsuz
      Abstract: White Slip ware, both White Slip I and II, and Monochrome ware are Middle to Late Bronze Age Cypriot pottery types found across a large area of the Eastern Mediterranean region. A vast quantity of these wares has also been uncovered in Tell Atchana/ancient Alalakh in Hatay in southern Anatolia. We analysed a total of 56 White Slip (n = 36) and Monochrome potsherds (n = 20) from Tell Atchana using XRF, ICP–MS and petrographic thin-section methods. The main aim of the study was to explore the compositional characteristics of the wares and to determine whether they are local imitations of the Cypriot White Slip and Monochrome wares or represent Cypriot exports to this region. The analytical results proved that White Slip I and II were produced from raw clay of mafic and ultramafic source rocks exposed in the Troodos Massif, available in the Limassol area of southern Cyprus and traded to Tell Atchana. Examples of Monochrome ware excavated in Tell Atchana were also imported to the region, most probably from east/north-east Cyprus. These results demonstrate a close trading connection between Tell Atchana/Alalakh and southern Cyprus during the Middle to Late Bronze Age.

  • Characterization of Materials and Artistic Techniques on Two 17th-Century
           Neapolitan Wood Sculptures
    • Authors: D. Fico; M. Faraco, A. Pennetta, D. Rizzo, G. E. De Benedetto
      Abstract: Two sculptures of Gaetano Patalano, one of the most important Italian sculptors of the late 17th century, were analysed to study the stratigraphy, the organic and inorganic materials, and to distinguish the original layers from the repaintings. Samples taken from the Immacolata Concezione and from San Gaetano da Thiene (Santa Chiara church, Lecce, Italy) were studied by optical microscopy, μ-Raman spectroscopy and Py-GC–MS. Different binders and pigments were used for the preparatory layers on the different parts of the statues: the results demonstrate that Patalano mastered the various materials and techniques, and that his choices have allowed his carving ability to be emphasized.

  • Improvements in Archaeomagnetic Dating in Western Europe from the Late
           Bronze to the Late Iron Ages: An Alternative to the Problem of the
           Hallstattian Radiocarbon Plateau
    • Authors: G. Hervé; P. Lanos
      Abstract: We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce. Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies.

    • Authors: W. J. Stemp; H. J. Lerner, E. H. Kristant
      Abstract: Few microwear studies have been conducted on tools made from quartzite. Most rely on visual observation of microwear features using optical light microscopes and scanning electron microscopes. Quantification of microwear on quartzite tools is extremely rare, even though numerous methods to mathematically document surface roughness have been applied to other silicate tools. In this paper, laser scanning confocal microscopy (LSCM) was used to document surface roughness on four experimental scrapers made from two different subtypes of Mistassini quartzite that were used on either fresh or dry deer hide. Surface roughness data were analysed using area-scale fractal complexity (Asfc). The results of this test case indicate that Asfc can effectively discriminate between the unused and used regions on the quartzite tools based on surface roughness, and that it can also discriminate between surface roughness produced by working dry versus fresh hides. Differences in the subtypes of Mistassini quartzite did affect surface roughness, but not significantly enough to prevent discrimination of the dry and fresh hide-working tools. Although the use of the Asfc parameter for lithic microwear analysis requires further testing, these first results suggest it could be a reliable technique to mathematically document and discriminate wear patterns on archaeological quartzite tools.

  • The Analysis of Late Bronze Age Glass from Nuzi and the Question of the
           Origin of Glass-Making
    • Authors: A. J. Shortland; S. Kirk, K. Eremin, P. Degryse, M. Walton
      Abstract: This paper re-analyses a considerable corpus of glass from the Late Bronze Age site of Nuzi, found near Kirkuk in Iraq. SEM–WDS and Sr and Nd isotopic analysis were applied, in addition to cataloguing the glass. The work showed that the glass technology at Nuzi was subtly different from contemporary Egyptian sites, using different ways of opacifying and working glass. At least two, perhaps three, Near Eastern production sites are postulated. The range of glass colours and the skill of their application at Nuzi was perhaps not on a par with the Egyptian sites. This led to a reconsideration and review of the accepted wisdom that the Near East is the source of the innovation that is glass-making. This opinion is based on limited textual and iconographic sources and is dominated by an erroneous early date for a very developed Nuzi glass industry along with a few finds of glass vessels in early contexts. Some of this evidence has now been at least questioned, suggesting that glass-making in Egypt, at least as early as the middle of the 15th century bc, and probably earlier, is no later than that in the Near East. It is argued that it is far from clear that the Near East was the source of the innovation and that a more cautious approach would better fit the evidence.

  • A Study of Biodeterioration and Chromatic Alterations of Painted and
           Gilded Mummy Cartonnage at the Saqqara Museum Storeroom, Egypt
    • Authors: M. F. Ali; M. M. A. Mansour, N. M. Badr, M. Z. M. Salem
      Abstract: Microbial biofilms have developed on the surfaces and within the painted and gilded layers of mummy cartonnage at the Saqqara museum storeroom in Giza, Egypt. SEM–EDX, XRD and FT–IR–ATR techniques were applied to analyse the coloured and gilded materials, ground layer, textile support and binder used for the cartonnage. Aspergillus niger (24.8%), Penicillium chrysogenum (21.5%) and a novel cartonnage-biodegrading bacterium, Bacillus sonorensis (23.7%), were the most abundant microbes growing over the cartonnage surface. In addition, Aspergillus tamari (15.4%), A. fumigates (8.1%) and Fusarium solani (6.5%) were identified. The pigments comprised Egyptian blue (cuprorivaite), cinnabar (red), orpiment (yellow) and green pigment made from a mixture of cuprorivaite and orpiment. Gold leaf was used for the gilded layer, calcium carbonate and gypsum comprised the ground layer, gum arabic was the binding medium and the fibre base was a fine linen textile. Microbial colonization tests were performed on aged cartonnage replica samples made from linen and pigments of similar composition to ancient pigments found in the cartonnage. Each sample was inoculated separately with A. niger, P. chrysogenum and B. sonorensis. Yellow orpiment samples were the exception, as no colour change was detected after colonization by the examined micro-organisms.

  • An Approach to the Diagnosis of Craniofacial Fibrous Dysplasia from the
           2500-Year-Old Remains of a Skull from Ancient China
    • Authors: Z. Z. Shi; Q. Zhang, K. L. Cheng, H. Shao, D. Zhao, B. T. Sun, J. Yu, Z. C. Sun, M. C. Li, L. Guo, H. Zhu, Q. C. Zhang, Y. H. Huang
      Abstract: A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low-magnification images using a 3D deep-field microscope had an irregular honeycomb-like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin-embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non-invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases.

      Abstract: Chemical characterization reveals intra-source variation in obsidian from the Paredón source area in Puebla and Hidalgo, Mexico. Two chemical sub-sources of obsidian from Paredón are spatially discrete and cannot be distinguished by visual characteristics. To facilitate future investigations of the prehistoric exploitation of these sub-sources, an inter-laboratory comparison of elemental concentrations is presented based on neutron activation analysis and several XRF instruments.

  • Breaking Traditions: An Isotopic Study on the Changing Funerary Practices
           in the Dutch Iron Age (800–12 bc)
    • Authors: L. M. Kootker; C. Geerdink, P. W. Broeke, H. Kars, G. R. Davies
      Abstract: Urnfields in the Dutch river area were replaced by cemeteries with a mixture of cremation and inhumation graves around the sixth century bc. This study provides the first biogeochemical evidence that the Iron Age communities were heterogeneous in terms of geological origins. The high percentage of non-locally born individuals (~48%) supports the hypothesis that the change in burial practice was the result of the influx of foreign people, who were being allowed to keep their own burial customs, whereas some of the local inhabitants adapted the burial rites of foreign cultures, leading to a heterogeneous burial rite for some centuries.

  • A Comparison Study of Middle Bronze Age II Daggers and Their Rivets as a
           Tool for a Better Understanding of Their Production
    • Authors: T. Kan-Cipor - Meron; S. Shilstein, Y. Levi, S. Shalev
      Abstract: The Middle Bronze Age II is a period during which there exists a contemporaneous usage of arsenic copper and tin bronze for metal weaponry production. In order to learn more about the alloys used in this period, the blades and rivets from 65 daggers of two significantly different types, which were discovered at the Rishon LeZion (RL) cemetery, Israel, were tested by the non-destructive method of X-ray fluorescence (XRF). The results reveal new knowledge of the alloys selected for dagger and rivet production, both of which represent fine examples of the Middle Bronze Age II Southern Levant in metal industry.

  • Prehistoric Settlement, Mobility and Societal Structure in the Peak
           District National Park: New Evidence from Ceramic Compositional Analysis
    • Authors: K. V. E. Cootes; P. S. Quinn
      Abstract: Detailed compositional and technological analysis of a large assemblage of prehistoric ceramics from numerous sites situated within the Peak District National Park has been used to explore the settlement patterns, societal structure, mobility and interaction of the populations that inhabited this area during the Early Bronze Age to Early Iron Age. A surprising pattern emerges of the widespread dominance of a single, geographically restricted temper type, which appears to have been transported and mixed with locally procured clay and used to produce pottery at numerous different sites. The distribution of this and several other compositional groups are defined via thin-section petrography and compared to raw material field samples. The resulting patterns are used to assess the validity of previous theories about prehistoric life in this region during the third to first millennia bc.

  • A Comparative Study of the Early High-Fired Ceramic Shards from
           Dongtiaoxi, Zhejiang (China)
    • Authors: L. T. Yan; Y. Huang, M. Liu, L. Liu, L. Li, S. L. Feng, X. Q. Feng
      Abstract: There is a generally accepted view that there is an obvious distinction between proto-porcelain and stamped stoneware. However, some early shards unearthed from the Dongtiaoxi region (northern Zhejiang) inspire people to rediscuss the relationship between them, because it is difficult to identify them as proto-porcelain or stamped stoneware. In this work, we have collected samples from three of the earliest kiln sites (Piaoshan, Beijiashan and Nanshan) in the Dongtiaoxi region. We have analysed the chemical composition, firing temperature and phase composition of the samples. Comparing samples from the three kiln sites, we find that, from Piaoshan and Beijiashan to Nanshan, there has been progression in the manufacturing technology. The Shang proto-porcelain and the stamped stoneware from Nanshan have similar raw materials, firing temperatures and body phase compositions—and they have obviously different decorative appearances, such as glazing or stamping. For ceramics from Piaoshan and Beijiashan, there is no clear distinction between glazed and unglazed samples. We believe that in the Dongtiaoxi region, the difference in the decoration between proto-porcelain and stoneware became obvious up to the time of the Nanshan production but that, subsequently, two different paths for the development of high-fired ceramics began to diverge.

  • Flint and Quartzite: Distinguishing Raw Material Through Bone Cut Marks

      Abstract: Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated' Can cut marks made with different types of the same raw material type be characterized and differentiated' The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra-sample and inter-sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts.

  • Quantifying 3D Micro-Surface Changes on Experimental Stones Used to Break
           Bones and Their Implications for the Analysis of Early Stone Age Pounding
           Tools
    • Authors: A. Benito-Calvo; A. Arroyo, L. Sánchez-Romero, M. Pante, I. Torre
      Abstract: We present a new method to assess use-wear formation processes of pounding tools used to break bones based on a combination of conventional microscopy, optical 3D surface measurements obtained with a confocal microscope and GIS analysis. The method involves 3D alignment and 3D surface change inspection techniques along with a surface morphometric characterization and 2D spatial pattern analysis, to measure the spatital distribution of significant changes in surface topography of pounding tools. Our results show that microscopic changes can be detected in the surfaces of hammers and anvils after bone breakage activities are performed. Use-wear on the active elements (hammers made on basalt and quartzite) occurred over a larger area than was observed on the passive element (quartzite anvil), but the latter often exhibited deeper modifications. Tool surfaces generally developed smoother topography with increased use, but grain microfracture also appeared with greater frequency over time. This methodology offers highly accurate and statistically robust analyses of microscopic use-wear traces that can be applied to the analysis of archaeological pounding tools.

  • Geochemical Methods for Sourcing Lava Paving Stones from the Roman Roads
           of Central Italy
    • Authors: M. Worthing; J. Bannister, R. Laurence, L. Bosworth
      Abstract: This paper documents the results of in situ analysis of 306 lava paving stones and 74 possible source rocks using pXRF. Data were collected from sites both in the city of Rome—on major roads beyond the city (including the Viae Flaminia, Cassia, Clodia, Praenestina and Appia)—and in the city of Ostia. Comparison of the pXRF data with lava compositional data from the geological literature allows broad identification of possible sources. The results point to quite distinctive patterns of exploitation for the city of Rome and Ostia, utilizing the Alban Hills lava flows, and the roads of the middle Tiber Valley, drawing on lava flows associated with the Vico and Sabatini volcanoes. The results show the potential of pXRF to produce data to elucidate the exploitation of lava flows for paving the Roman roads.

  • Archaeomagnetic Dating of Pyrotechnological Contexts: a Case Study for
           Copper Smelting Sites in the Central Timna Valley, Israel
    • Authors: I. Peters; L. Tauxe, E. Ben-Yosef
      Abstract: This study is focused on establishing age constraints for several copper slag deposits at the centre of the Timna Valley (Israel) via reconstruction of their ancient geomagnetic intensities as recorded by the individual slag samples at the time of their formation. The results show a correlation between the location of the slag deposits (labelled as individual ‘mounds’ in our survey) and their inferred ages, reflecting varying socio-economic and political dynamics in the region. While the slag mounds found at the unprotected foothills represent a variety of dates (mostly Early Islamic), the slag mounds on the hilltops are chronologically constrained to the early Iron Age (late 11th to 10th centuries bce), supporting the idea for a need for protection during this period. Furthermore, in comparing the new data with previous archaeomagnetic studies from Timna, we can assert the existence of simultaneous copper production at the archaeological Sites 30, 30a and 34. This gives further support to the claim of intense smelting in the central Timna Valley during the early Iron Age. Finally, this project demonstrates the potential of archaeomagnetic experiments to provide chronological insights, and their particular advantage in addressing pyrotechnology-related cases.

  • High-boron and High-alumina Middle Byzantine (10th–12th Century ce)
           Glass Bracelets: A Western Anatolian Glass Industry
    • Authors: C. M. Swan; Th. Rehren, L. Dussubieux, A. A. Eger
      Abstract: The trace element boron is present in most ancient glasses as an impurity, and high boron (≥ 300 ppm) marks raw material sources that are geologically specific and relatively uncommon. Recent analyses of Byzantine glass with high boron contents suggest that glass-making was not limited to the traditional regions of the Levant and Egypt, and a production origin in or near western Anatolia is proposed. Glass bracelets from Ḥiṣn al-Tīnāt in southern Turkey give fresh evidence for the production and circulation of high-boron glasses that closely correlates with object typology. The patterning of findspots suggests that high-boron glass was closely connected to the Byzantine world.

      Abstract: This paper presents and discusses the results of residue analysis conducted on 78 ceramic lamps found in archaeological excavations in ancient Jerusalem, in an attempt to identify the types of oils used and the reasons for their preferential choice. The oil lamps chosen for the study were taken from a variety of contexts, which represent the different periods during which Jerusalem was settled and the different sectors of the city. The results of the study show that even the most mundane activity of lighting using oil held within it social and economic choices, as mirrored in the different excavation areas.

  • Multi-analytical Studies of Archaeological Chinese Earthen Plasters: The
           Inner Wall of the Longhu Hall (Yuzhen Palace, Ancient Building Complex,
           Wudang Mountains, China)
    • Authors: X. Ma; G. Wei, C. Grifa, Y. Kang, H. Khanjian, I. Kakoulli
      Abstract: The Yuzhen Palace is one of the nine palaces in the Ancient Building Complex built by order of the Yongle Emperor during the Ming dynasty. The buildings were built with dressed black bricks. As a result of the planned national South–North Water Diversion project, the water level in the Danjiangkou Reservoir that surrounds the Yuzhen Palace was expected to rise by approximately 15 m. To avoid submersion of the site, three gates were elevated by 15 m in 2013 and other buildings dismantled, for later reconstruction. The characterization of the construction materials has therefore become of primary importance. Here, we present results on the plasters of the Longhu Hall. The analysis of materials involved a multi-analytical approach combining optical and electron microscopy with X-ray and vibrational spectromicroscopies and thermogravimetry. The results indicated the use of two earthen plaster layers and a whitewash finish coating applied over a thin preparatory intermediate layer to improve the adherence of the finish coating to the earthen plaster. Ramie and straw fibres identified in the earthen plasters were added to reduce shrinkage and cracking during drying. The raw materials used and the application technique pointed to a well-established construction industry using traditional earthen building materials together with lime technology.

  • The Impact of Climate Change on an Archaeological Site in the Arctic
    • Authors: J. Hollesen; H. Matthiesen, B. Elberling
      Abstract: Climate change may accelerate the degradation of archaeological sites in the Arctic and lead to a loss of important historical information. This study assesses the current preservation conditions and the processes controlling the physical and chemical stability of the Qajaa kitchen midden in western Greenland. Currently, the site is well protected by low ground temperatures, permafrost and a high water/ice content, keeping the deposits anoxic. Based on 5 years of monitoring data, degradation experiments and model simulation, our results suggest that the combined effects of permafrost thaw, thermal and hydrological erosion and oxygen exposure may lead to substantial loss of archaeological evidence before the end of the 21st century.

      Abstract: To understand the nature of trade/exchange of ‘Basque’ copper kettles and their fragments among Indigenous communities from Québec to Ontario, Canada, we examined 948 copper samples from 75 archaeological sites. We found that 936 samples were sortable into 11 coarse chemical groups: seven biased towards Ontario, three favouring Québec and only one balanced between the two provinces. This pattern may represent kettles and pieces ‘mostly traded’ or ‘mostly kept’ by Indigenous groups within Québec. Chemical group distribution within individual provinces is complex. A tentative chronology of copper chemical groups provides additional insight into the complex trading/exchange patterns among the Indigenous groups of southern Ontario.

    • Authors: M. Verità; I. Biron, A. Cagnini, S. Porcinai, F. Barbe
      Abstract: The so-called Venetian enamelled coppers are a group of objects produced in Italy during the 15th century. Up to now, about 300 objects have been recognized in private collections and in European and US museums. At the end of 19th century, a Venetian origin was suggested, but their provenance is still debated. In this study, the enamel compositions from 22 enamelled copper products from Italian and French collections have been analysed by invasive and non-invasive techniques. A comparison of the results with Tuscan and Venetian glass databases reinforces the suggestion of a Tuscan (most probably Florentine) origin for these works of art.

  • Characterizing the Alabastro listato or fiorito of Hierapolis in Phrygia:
           A Simple Method to Identify its Provenance using Carbon Stable Isotopes
    • Authors: M. Brilli; F. Giustini, P. M. Barone, A. Fayek, G. Scardozzi
      Abstract: Alabastro listato or fiorito of Hierapolis in Phrygia was a prestigious coloured marble widely used in Roman architecture and decoration. This stone is generally identified in artefacts on autoptic examination, but it may sometimes be confused with alabasters of different provenances. This study describes a simple, but effective, scientific method to contribute to the determination of Hierapolis alabaster. Due to its unique genetic context, it is characterized by a distinctive carbon isotope signature. A comparison between the stable carbon isotope data from this paper and from the literature confirms the uniqueness of the isotopic character of Hierapolis alabaster. Carbon isotopes can ensure a reliably provenance attribution of the alabaster artefacts along with visual recognition by an expert eye.

  • A Study on Black-Body Celadon Excavated in The Altar Guan and Literature
           Ge (Longquan Ge) Kilns by EDXRF
    • Authors: Y. Huang; L.-T. Yan, H.-Y. Sun, X.-Q. Feng
      Abstract: Samples of celadon were collected from the Altar Guan Kiln in Hangzhou, and from the Xiaomeizhen and Xikou Kilns, two subordinate kilns of the Longquan Kiln producing black-body celadon called Literature Ge. Both the elemental contents in the sample bodies and the glaze were measured. The results reveal that the sample bodies contain fingerprint information for provenance, while this was lost in the glaze during the production process. The TiO2, MnO and Rb2O contained in the bodies are fingerprints to distinguish between celadons from the Xiaomeizhen and Xikou Kilns. In the Altar Guan Kiln, some low-TiO2 samples were found and their body colour is much lighter than some others, but they do not differ with regard to iron content. This indicates that both titanium and iron are indispensable for the blackness of the bodies: they may react to form some black minerals during the firing process. Ultimately, samples from the Literature Ge and Altar Guan Kilns differ in their body constituents. Principal component analysis reveals that the samples can be divided into two groups, corresponding to the two different areas.

           a Case Study of a Medieval Pfennig
    • Authors: L. Kučera; L. Richtera, M. Zmrzlý, M. Jarošová, P. Kučerová, P. Bednář
      Abstract: The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non-destructive (i.e., scanning electron microscopy/energy-dispersive X-ray spectroscopy, X-ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross-section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed.

  • Towards a Chronology of the Jerzmanowician—a New Series of Radiocarbon
           Dates from Nietoperzowa Cave (Poland)
    • Authors: M. T. Krajcarz; M. Krajcarz, B. Ginter, T. Goslar, P. Wojtal
      Abstract: The period around 50 000–35 000 years ago constitutes one of the most debated research issues in European archaeology of the Palaeolithic. In this time period, the transition from the Middle to the Upper Palaeolithic took place. Locally, in different areas of Europe, this shift is recorded in so-called transitional assemblages. The eastern fringe of these transitional assemblages is represented by the Jerzmanowician, the unit described on the basis of a lithic assemblage from Nietoperzowa Cave (Poland). The unit is a part of a European transitional complex called the Lincombian–Ranisian–Jerzmanowician. Up to now, the radiocarbon dates presented in the literature have only allowed us to set the age of the Jerzmanowician at c.40 000–45 000 ka cal bp. In this study, we present 42 new radiocarbon dates. We attempt to set the archaeological record of the Jerzmanowician from Nietoperzowa Cave in an accurate chronological framework, based on Bayesian statistical processing of radiocarbon dates. We conclude that the lower boundary of layer 6 in Nietoperzowa Cave can be statistically located in the range 44 000–42 000 cal bp and the upper limit for the Jerzmanowician is estimated to c.31 000 cal bp. New data raises a question on the correlation with upper layer 4. In the light of the new chronology, the attribution of the archaeological inventory from layer 4 to the Jerzmanowician seems questionable.

  • ‘Guard the Good Deposit’: Technology, Provenance and Dating of
           Bipyramidal Iron Semi-Products of the Durrenentzen Deposit (Haut-Rhin,
           France)
    • Authors: S. Bauvais; M. Berranger, M. Boukezzoula, S. Leroy, A. Disser, E. Vega, M. Aubert, P. Dillmann, P. Fluzin
      Abstract: In the early days of iron metallurgy in Western Europe, the most widespread type of ‘trade iron’ (semi-product) was bipyramidal in shape. Although they are frequently found, little is known about how they were manufactured and circulated, or even about their age. An interdisciplinary approach was applied to the Durrenentzen deposit (Haut-Rhin, France), the third-largest in Europe in terms of artefact quantities, in an attempt to reconstruct the technological, social and economic context that caused them to be abandoned. A morphometric study of the 51 iron bars revealed a high degree of homogeneity, despite variations in detail. Four objects were selected for archaeometric studies. Metallographic analyses show internal differences (quality of the material, nature of the alloys and manufacturing techniques). Chemical analyses also showed different provenances. Finally, radiocarbon analyses of the carbon in steel (iron/carbon alloy) linked this deposit to the early Iron Age. This study provided the first benchmark for more general research, significantly changing perceptions of the economics of iron at the beginning of the Iron Age.

  • Early Imports in the Late Bronze Age of South-Western Iberia: The Bronze
           Ornaments of the Hypogea at Monte da Ramada 1 (Southern Portugal)
    • Authors: P. Valério; M. F. Araújo, A. M. M. Soares, R. J. C. Silva, L. Baptista, R. Mataloto
      Abstract: The composition and manufacture of Late Bronze Age metallic artefacts from funerary and domestic contexts of southern inland Portugal was studied. The prevailing trend comprises binary bronzes (10.3 ± 2.1 wt% Sn) showing deformed equiaxial grains, annealing twins and slip bands. The alloy composition is somewhat independent of artefact type, while the manufacture seems to rely on artefact function and the skilfulness of the metallurgist. The technological characteristics were linked with archaeological and chronological features, disclosing some artefacts of uncommon composition, such as low-tin bronze bracelets (4.3–7.1 wt% Sn) associated with ornaments of exotic materials (glass and Egyptian faience beads, and also ostrich egg shell beads). The assemblage testifies to an archaic trade with the Mediterranean region before the establishment of the first Phoenician colonies on the southern Iberian coast.

           Techniques: The Case Studies of the Domus delle Bestie Ferite and the
           Domus di Tito Macro (Aquileia, Italy)
    • Authors: M. Secco; S. Dilaria, A. Addis, J. Bonetto, G. Artioli, M. Salvadori
      Abstract: The paper reports the results of a research project aimed at the characterization of the floor bedding mortars of two Roman houses in Aquileia (north-eastern Italy), the Domus delle Bestie Ferite and the Domus di Tito Macro. Seventy floor bedding mortars of the two domus were selected and almost half were fully minero-petrographically characterized by means of optical microscopy operated in transmitted light (OM-TL), X-ray powder diffraction analyses coupled with quantitative phase analysis by means of the Rietveld method (XRPD-QPA) and scanning electron microscopy with EDS microanalysis (SEM–EDS). The results indicate an evolution of the mortar preparation techniques over time in the mosaic of both houses. The materials are compared to the traditional Roman recipes for specific construction techniques.

  • The Chemical Composition and Production Area of Early Western Zhou
           Proto-Porcelain Unearthed from Yejiashan Cemetery, Suizhou, China
    • Authors: Y. B. Yu; F. C. Huang, J. F. Cui, C. J. Guo, J. L. Chen
      Abstract: The bodies and glazes of 27 early Western Zhou proto-porcelain samples from Yejiashan cemetery, Hubei Province, were analysed using LA-ICP–AES, SEM, XRD, a thermal expansion instrument and other analytical methods. The results indicated that the bodies of all samples were characterized by high silicon and low aluminium, and were made with porcelain stone raw materials found in the south of China. The glazes are typical of high-temperature calcium glazes of the CaO (MgO) – K2O (Na2O) – Al2O3 – SiO2 series, with relatively high Mn and P content, which was probably caused by the addition of plant ashes. The physical properties and phase compositions of Yejiashan proto-porcelain show that firing processes were still in the early stages of development in ancient China. Multivariate statistical analyses indicated that Yejiashan proto-porcelain might have come from the Deqing area, in Zhejiang Province. These results provide new archaeological evidence for research on issues related to material flow in the Western Zhou dynasty.

  • Examination and Analysis of Etruscan Wall Paintings at Caere, Italy
    • Authors: B. Klempan; K. Helwig, F. Colivicchi
      Abstract: In 1983, the excavation of the ancient city of Caere near Rome, which became a UNESCO World Heritage Site in 2004, led to the unearthing of an underground sanctuary dating from the early third century bc. Known as the ‘Hypogaeum of Clepsina’, it consists of an underground room decorated with frescoes, drawings and inscriptions. The initiation of a new excavation campaign at Caere in 2012 provided the opportunity to study this rare example of Etruscan wall paintings of a non-sepulchral nature from the Hellenistic era. The paintings were documented, photographed and samples were removed for analysis using a combination of scientific techniques. The observation that at least some of the painting was done on wet plaster supports the conclusion that the frescos are contemporaneous to the plastering of the walls in the hypogaeum in approximately 273 bc. The plaster is lime-based and aggregate materials include potassium feldspar, clinopyroxene, quartz, hematite and magnetite. No organic binding medium was identified in the paint, suggesting a lime water binder. Paint materials identified are Egyptian blue, red iron oxide (hematite), yellow iron oxide (goethite), charcoal black, quartz, silicates and calcite. All the paint samples show a mineral accretion layer at the upper surface, caused by recrystallization of salts.

  • The Contribution of Transmission Electron Microscopy (TEM) to
           Understanding Pre-Columbian Goldwork Technology
    • Authors: E. Vindel; J. García, C. Gumiel, V. López-Acevedo, M. Hernando
      Abstract: This paper highlights the contribution of transmission electron microscopy (TEM) when combined with scanning electron microscopy and energy-dispersive X-ray microanalysis (SEM/XEDS) to characterize objects in archaeology. The application of TEM in archaeology is not yet a common tool, but it may provide data that are significant to understanding pre-Columbian gold metallurgy, specifically the gilding and silvering methods. Two gilded rods were studied using a combination of TEM and SEM/XEDS techniques. The objects were found at the Atacames archaeological site, in the Esmeraldas region, Ecuador, which was occupied between ad 750 and 1526 by the Atacames culture. The microchemical and structural results of the inner and the external gilded part of the artefacts support the hypothesis of a gold diffusion to the surface enhanced by chemical treatment with chloride-rich solutions, heating and successive annealing processes. The present study reveals that microstructural investigation by TEM provides useful information with which to investigate the techniques used to modify the chemical surface composition of pre-Columbian artefacts.

      Abstract: The application of solid state electrochemistry techniques for the characterization and dating of leaded bronze objects is described. Characteristic voltammetric signatures of copper and lead corrosion products were used as markers of more or less prolonged corrosion periods. The proposed methodology was applied to samples from the Roman archaeological sites of Valeria (Spain) and Gadara (Jordan), Roman and medieval sites in Xàtiva (Spain), and modern statuary exhibited outdoors, on the campus of the Universitat Politècnica of Valencia, Spain, covering a time interval between the fourth to second century bc and the 20th century ad. For such samples, the ratio between the signals for copper and lead corrosion products decreased monotonically with the corrosion time. This variation was modelled on the basis of thermochemical and kinetic considerations, the experimental data being consistent with a potential rate law for the corrosion process.

  • Stable Isotope and Radiocarbon Dating of the Remains of the Medieval Royal
           House of Aragon (Spain) Shed Light on Their Diets, Life Histories and
           Identities
    • Authors: B. Martínez-Jarreta; C. Sosa, C. Laliena, B. Budowle, R. E. M. Hedges
      Abstract: The remains of 20 individuals buried in three different pantheons, putatively pertaining to the medieval Royal House of Aragon, were analysed for their isotope (14C, 13C and 15N) measurements. The radiocarbon dates and stable isotope data contributed to identifying individual members and, combined with additional osteological and taphonomic information, as well as documentary evidence, provided a fuller picture of the diets and life histories of particular people. This group comprised the first members of a royal dynasty that ruled the Kingdom of Aragon before the Spanish Crown was established, and that played a significant role in the reconquest of the Iberian Peninsula from Muslim control, this being of paramount importance in the Spanish and European history.

  • Identification of the Residue in the Bolgar Medieval Sphero-Conical Vessel
           by Gas Chromatography – Mass Spectrometry
    • Authors: V. Pozhidaev; A. Kamaev, A. Nuretdinova, M. Kovalchuk, E. Yatsishina, E. Greshnikov, M. Sivitskiy, E. Devlet
      Abstract: The Golden Horde sphero-conical vessel retrieved from the ruins of the medieval city of Bolgar (Russia, Republic of Tatarstan) during archaeological excavations, which contained residue in the form of encrustation on the bottom and the wall, was analysed in the NRC ‘Kurchatov Institute’ by X-ray phase analysis and high-performance liquid and gas chromatography with MS detectors (HPLC–MS, GC–MS). The GC–MS method established that the residue from the sphero-conical vessel was comprised primarily of abietic acid derivatives (around 46%) and retene, which is polycyclic aromatic hydrocarbon (around 27%); this means that turpentine exuded from the stems of certain species of coniferous trees, called resin and subsequently heat-treated, was poured into the vessel. Researchers have been trying to decipher the function of these mysterious vessels for 200 years, and this is the first time that resin stored in a sphero-conical vessel has been documented. Potentially, this vessel was probably used as a personal ‘medical kit’.

  • A Better Shade of Black: Effects of Manufacturing Parameters on the
           Development of Ancient Black Bronzes*
    • Authors: A. Benzonelli; I. C. Freestone, M. Martinón-Torres
      Abstract: Copper alloys with controlled contents of Sn, Ag and Au were treated with methods and solutions that mimic those used in ancient and traditional procedures for the production of black bronze. Examination of the resulting patinas with colorimetry, SEM–EDS, TEM, Raman spectroscopy and XRD revealed no systematic differences according to the fabrication method, whereas patina homogeneity and colour in those alloys that did not contain precious metal were affected by superficial work. Patina microstructure determines adherence and coverage, and depends upon the solution used irrespective of the alloy composition, but the colour of the patina is mainly related to the alloy composition. Gold promotes the development of cuprite, slowing the oxidation to tenorite in the corrosion process. Gold additions produce a more uniform patina as well as a desirable blue–black tone, which is likely to have been a factor in alloy selection.

  • On the Metal-Leaf Decorations of Post-Byzantine Greek Icons
    • Authors: G. P. Mastrotheodoros; K. G. Beltsios, Y. Bassiakos, V. Papadopoulou
      Abstract: Metal leaves were widely used as decorative materials in post-Byzantine ritual painting. Fifty-two icons (mid-15th to mid-19th centuries) were studied by means of analytical techniques in order to reveal the materials and techniques encountered in their metal-leaf decorations. High-purity gold leaf was used throughout the studied period. Silver was employed rarely and mostly during the latter part of the period in consideration, while metal powders were mostly used from the mid-18th century onwards. The identification of a gold–silver powder mixture and an ‘electrum’-type alloy are among the reported findings, which are novel for post-Byzantine icons. Three micromorphologically distinct highlighting techniques were also documented.

  • Integrated Analytical Techniques for the Study of Colouring Materials from
           Two Megalithic Barrows
    • Authors: C. Oliveira; A. M. S. Bettencourt, A. Araújo, L. Gonçalves, I. Kuźniarska-Biernacka, A. L. Costa
      Abstract: We have determined the composition of rock art pigments from two megalithic barrows located in the north of Portugal. The use of XRD, SEM–EDS and FT–IR spectroscopy confirmed the presence of hematite and kaolinite in the red pigments from the Eireira barrow, and kaolinite in the white pigment from the Leira das Mamas barrow. The organic composition of the pigments was studied by GC–MS, suggesting that the red sinuous lines and dots from the Eireira barrow were prepared with cooked or heated algae and/or aquatic plants, with egg as binder, while the white pigment from the Leira das Mamas barrow revealed a mixture of vegetable oils for kaolinite moulding, which could be stabilized by temporary exposure to high temperatures. The multi-analytical approach used on this study of megalithic pigments allowed the recovery of important data about north-western prehistoric communities, namely the way in which they exploited existing resources and their ability to transform them.

    • Authors: S. R. Amato; D. Bersani, P. P. Lottici, P. Pogliani, C. Pelosi
      Abstract: This paper presents the results of analyses carried out on three decorative phases of the presbytery of the church of Santa Maria Antiqua al Foro Romano in Rome: the fourth-century ad mosaics setting bed; the Adoration of the Cross, dated to the papacy of John VII (ad 705–7); and the paintings in the apse of the Pope Paul I (ad 757–68) phase. The research allowed the characterization of the painting techniques, pigments, organic compounds and degradation products by means of a video microscope, optical microscopy, and μ-Raman and FT–IR spectroscopy, contributing to a better understanding of the changes in the techniques and materials used throughout the centuries in one of the most relevant medieval Christian monuments in Western Europe.

  • Chemical Alteration of Lithic Artefacts: an Experimental Case Study on the
           effect of Guano on Stone Flakes and Its Contextualization in the
           Archaeological Assemblage of Azokh Cave (Southern Caucasus)
    • Authors: L. Asryan; A. Ollé, N. Moloney, T. King, J. Murray
      Abstract: Chemical weathering of archaeological material is well known; however, while there have been a number of experimental studies demonstrating different types and degrees of chemical alteration on faunal remains, little attention has been paid to stone tools, and the few studies that exist relate mainly to siliceous materials and water-induced chemical alteration. Azokh Cave, located in the South Caucasus, contains a Middle Pleistocene to Holocene infill, and detailed macro- and microscopic examination of the lithic assemblages recovered there indicates potential chemical weathering of the stone artefacts. The cave is also currently home to one of the largest bat colonies in the region, and their guano forms a significant component of the infill of the inner galleries. Based on these two factors, an experimental pilot study was set up to artificially chemically alter a range of stone flakes produced specifically for the task, in order to determine the nature and likely cause of weathering. The experimental flakes, produced from different raw materials, were buried in fresh bat guano for up to two years. The results reported herein demonstrate that in a relatively short time, the highly acidic composition of bat guano strongly affects calcium-bearing rocks (e.g., limestone, basalt) altering their entire surface. Similar comparisons may be made with chemical alteration evident on archaeological lithics from Azokh Cave, suggesting that bat guano has played a significant role in diagenetic alteration.

  • C4-Plant Foraging in Northern Italy: Stable Isotopes, Sr/Ca and Ba/Ca Data
           
    • Authors: F. Lugli; D. Brunelli, A. Cipriani, G. Bosi, M. Traversari, G. Gruppioni
      Abstract: Human osteological samples (n = 23) taken from different anatomical parts of 11 individuals from the early modern (16th–18th century AD) site of Roccapelago (Modena, Italy) were systematically analysed for δ13C, δ15N and trace elements to investigate their diet. δ13C and δ15N correlate and show a high variability between individuals, attesting to the dietary contribution of C4 plants. This is supported by pollen analysis of the burial site samples, which revealed the presence of maize. δ15N correlates with Sr/Ca, suggesting that the main protein source could have been milk and dairy. We therefore interpret the strong correlation between δ13C and δ15N as evidence for C4-plant foraging practice and the exploitation of livestock for meat and milk, combined with possible direct intake of C4 plants. The Roccapelago site represents an important case study to track the evolution of the post-medieval diet and the introduction of maize cultivation in southern Europe, as also attested by historical sources.

  • Compositional Analysis of Ceramics from Goguryeo Fortified Sites in
           Central Korea
    • Authors: J. Choi; S. Yang, W. D. Gilstrap, D. Cho, M. D. Glascock
      Abstract: The aim of this paper is to investigate whether the ceramics from the Goguryeo fortified sites of the Han River region in central Korea were manufactured and consumed locally during the southern expansion of the Goguryeo State (475–551 ce). For this research, 88 ceramic samples from seven contemporary sites in the southern territories of Goguryeo were sampled and analysed by ceramic thin-section petrography and neutron activation analysis (NAA). In addition, to establish a possible chemical fingerprint at Hongryeonbong Fort 2, five clay specimens were also gathered and analysed from the pottery firing structure. The results of this analytical study indicate that the majority of the ceramics from the Goguryeo fortified sites of central Korea were produced and circulated within this newly acquired region. In addition, it is highly probable that Hongryeonbong Fort, which contains the remains of what may be ceramic firing architecture, is the place of production for the ceramics.

  • Multi-Technique Characterization of Adhesives Used in Medieval Jewellery
    • Authors: M. Aceto; E. Agosta, A. Arrais, E. Calà, E. Mazzucco, S. Lomartire, A. Agostino, G. Fenoglio
      Abstract: In this work, a multi-technique analytical approach was used to characterize adhesive samples taken from medieval chef d'oeuvres jewellery, three manuscript bindings and a crucifix produced in northern Italy between the 8th and the 11th century ad, according to art-historical evaluation and 14C dating executed on adhesives. These materials being complex mixtures, mostly of organic/inorganic nature, various analytical techniques were utilized to thoroughly elucidate their composition. A preliminary survey with portable X-ray fluorescence spectrometry (XRF), applied in situ, suggested the presence of inorganic phases. X-ray diffraction analysis was used to identify crystalline phases. Fourier transform – infrared and Raman spectroscopies were used to identify the major components. Finally, gas chromatography coupled with mass spectrometry was used to identify, in the most accurate way possible, the organic compounds present in the mixtures. The combined approach of non-invasive measurements, applied for the first time to such precious objects, and of micro-invasive techniques allowed a complete characterization of the samples, widening the present view on such poorly studied materials.

    • Authors: D. Motta; D. Keenan-Jones, M. H. Garcia, B. W. Fouke
      Abstract: This paper evaluates conveyance and flow characteristics for the Anio Novus, the aqueduct bringing water from the greatest distance to ancient Rome. Travertine accumulations, deposited from water on floor and walls, were used to reconstruct the flow rate and associated spatial and temporal variations. Hydraulic quantities (e.g., flow depth and velocity) markedly varied over the course of the aqueduct, implying that constraints such as topography and construction techniques were combined with hydraulic considerations to determine the aqueduct layout. Design practices differed along the aqueduct and channel size design was not based exclusively on anticipated carrying capacity, tending towards larger-than-necessary design based on experience.

  • Magnetic Alteration of Soils by Late Holocene Hunter–Gatherer Groups
           (Tierra Del Fuego, South America)
    • Authors: I. L. Ozán; M. J. Orgeira, C. Vásquez, M. Naselli
      Abstract: The present work aims to analyse the magnetic signature from the Late Holocene open-air archaeological deposits of hunter–gatherer ephemeral occupations. For this purpose, two profiles were sampled at the Marazzi 2 site in the north-western Isla Grande de Tierra del Fuego, Chile, in order to carry out studies of magnetic susceptibility, hysteresis cycles, back-field remanent magnetization, isothermal remanent magnetization and thermal variation of magnetic susceptibility at high and low temperature. Despite short-term occupations, the P1 profile shows a magnetic peak at a depth of ~30–70 cm due to magnetite, probably formed by anthropogenic activity related to combustion. The P2 profile instead yields an anomalous peak of coercivity (at a depth of 20–40 cm), which could also be anthropogenic, due to the presence of finely dispersed ancient ‘red ochre’. The red ochre is proposed to form anthropogenic thermal alteration of goethite associated with volcanic ash, the remnants of which were found in thin sections from the P2 subsoil.

  • Experimental Heating of Moravian Cherts and its Implication for
           Palaeolithic Chipped Stone Assemblages
    • Authors: M. Moník; Z. Nerudová, P. Schnabl
      Pages: 1190 - 1206
      Abstract: The applicability of colour, magnetic susceptibility and remanent magnetization measurements for the identification of heated or accidentally burned Palaeolithic cherts from Moravia (Czech Republic) is tested in this study. We conclude that all these methods are usable. Colour changes are best detectable in materials heated at between 250–350°C, while magnetic susceptibility and remanent magnetization change at higher temperatures, closer to 600°C. This latter temperature, however, is usually destructive for cherts and is probably evidenced by accidentally burned artefacts. With the use of the three methods, we managed to identify three probably heated chert artefacts from two early Upper Palaeolithic assemblages from Moravia.
