Black-on-red ware in the levant: A neutron activation analysis study

Black-on-red ware was widely used throughout the Eastern Mediterranean between about the 11th and 8th centuries BC. Its origins have been much discussed: its ubiquitous appearance throughout the region could be a result of either several manufacturing regions or a single place of manufacture associated with considerable trading in the ware.In the present study, neutron activation analysis has been carried out for 15 chemical elements in 58 specimens of black-on-red ware from Cyprus (11), Syria (26) and Palestine (21). The analytical results clearly separate the ware into three major groups, corresponding to origins in Palestine, Syria and Cyprus. The hypothesis of a single source of the ware is therefore not tenable. All 14 of the Syrian finds of the single-handled neck ridge juglet are closely grouped with the Cyprus samples, indicating extensive trade in this vessel from Cyprus to Syria. The Palestine samples clearly separate into two sub-groups. Arguments are presented suggesting that this indicates the ware from the two sub-groups was made at different times. The Cyprus group provides tentative evidence of several sites of manufacture on the island.     

The analysis of copper artifacts of the copper inuit

Metallography and neutron activation analysis have been used to investigate copper artifacts from 19th century archaeological sites associated with the “Copper Inuit” of the west-central Canadian Arctic. A knowledge of the source of the copper from which the artifacts were manufactured - native (local) copper or European (exotic) copper - is important, for example, to studies of the effects of European contact on utilization of native copper and on the general lifestyle of the Copper Inuit. Trace element analysis by neutron activation using the SLOWPOKE reactor has allowed local native copper, from the Coppermine River and Victoria Island, NW Territories, to be clearly distinguished from 19th century European smelted copper, which was found to contain higher concentrations of arsenic, antimony, nickel and selenium. Moreover, optical and scanning electron metallography revealed significant microstructural differences between native copper and the 19th century smelted copper. As a consequence it was possible to differentiate between native copper archaeological artifacts and those produced from smelted copper.     

Non-destructive Phase Analysis of Archaeological Ceramics using TOF Neutron Diffraction

Mineral phase analysis of ancient ceramics carried out by neutron diffraction yields complementary information to X-ray diffraction analysis. Since neutrons are highly penetrating, neutron diffraction in general allows non-destructive investigations of bulk samples rather than of surface layers or powdered material. This means complete, intact specimens can be studied. A time-of-flight (TOF) neutron diffractometer offers additional advantages considering experimental set-up, accommodation of large objects and data collection times. First test measurements with respect to archaeometric applications have been performed on different fragments of medieval Rhenish pottery using the TOF neutron diffractometer ROTAX at the spallation source ISIS, U.K. Phase fractions obtained from a Rhenish stoneware jar fragment compare well with those from a powder sample prepared from the same fragment. This finding indicates that reliable results can be obtained by illuminating a large piece or even a complete ceramic object without causing damage.     

Preliminary Provenance Research on Chinese Neolithic Pottery: Huating (Xinyi County) and Three Yellow River Valley Sites

Instrumental neutron activation analysis (INAA) was applied to sherds from the important site of Huating and, for comparison, several Neolithic sites in the valley of the Yellow River. We hoped to compare the compositions of two stylistically different ceramics found at Huating, and to evaluate the degree of compositional clustering and inter‐site resolution that could be expected in an area that is noted for its extensive, and possibly very homogeneous, loess deposits. In addition, pottery sherds from Huating have been examined by microscopic petrography. All of these results will provide needed input in the planning of research towards the formation of a Neolithic/Shang Dynasty ceramic database for future use in archaeological research in China.     

Disclosing mineralogical phases in medioeval iron nails by non-destructive neutron techniques

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples).     

AN ARCHAEOMETRIC STUDY OF MEDIEVAL GLASS FROM THE FIRST BULGARIAN CAPITAL,PLISKA (NINTH TO TENTH CENTURY AD)

Glass finds from the first Bulgarian capital, Pliska, have been analysed by instrumental neutron activation analysis. The analytical data, together with previous results from analysis of glass samples from the second Bulgarian capital, Preslav, were subjected to cluster and discriminant analysis. The local origin of part of the analysed samples was proven and some conclusions about the technology of production were possible.     

The Hungarian and Slovak sources of archaeological obsidian: an interim report on further fieldwork,with a note on tektites

This report describes the results of fieldwork carried out in the Zemplén Mountain area of north-eastern Hungary in 1975. The aim of this work was to locate and sample geological sources of obsidian which may have been used by prehistoric man. These sources are of increased importance since the work of Nandris (1975) showed that the Romanian “sources” do not produce workable obsidian. During the fieldwork three sources in Hungary were visited and sampled; one of these was the previously unlocated source of Csepegö Forräs. A number of other possible localities for geological obsidian are mentioned in 19th and 20th century geological and archaeological literature, and the present state of knowledge with regard to these is summarized. Further sources exist in central and in south-eastern Slovakia. These sources were not visited but material has been obtained from both areas. The central Slovak sources do not produce workable obsidian and are not therefore relevant to archaeological studies. Obsidian from three localities in south-eastern Slovakia is of good glassy quality and further fieldwork is now needed to check the validity of these localities as geological sources. Reference is made to obsidian sources in the western U.S.S.R., and the problem of the use of tektites in archaeological sites is discussed.The obsidian samples obtained during this work are currently being analyzed using neutron activation, in order to characterize the sources on the basis of their trace element analysis and thus to relate them to archaeological obsidian from central and eastern Europe.     

Tracing the origin of blue and white Chinese Porcelain ordered for the Portuguese market during the Ming dynasty using INAA

The existing documentary history of Chinese porcelain ordered for the Portuguese market (mainly Ming dynasty.) is reasonably advanced; nevertheless detailed laboratory analyses able to reveal new aspects like the number and/or diversity of producing centers involved in the trade with Portugal are lacking.In this work, the chemical characterization of porcelain fragments collected during recent archaeological excavations from Portugal (Lisbon and Coimbra) was done for provenance issues: identification/differentiation of Chinese porcelain kilns used. Chemical analysis was performed by instrumental neutron activation analysis (INAA) using the Portuguese Research Reactor. Core samples were taken from the ceramic body avoiding contamination form the surface layers constituents. The results obtained so far point to: (1) the existence of three main chemical-based clusters; and (2) a general attribution of the porcelains studied to southern China kilns; (3) a few samples are specifically attributed to Jingdezhen and Zhangzhou kiln sites. In a chronological point of view, for the studied samples we assist to an increasing improvement of the production procedure from late 15th till the 17th centuries of the Chinese porcelains sent to Portugal, especially enhanced by the association of late porcelains with refining processes of the original raw material, consistent with removal of more heavy minerals. In the case of some samples a kiln attribution was possible, but for the majority of the samples we haven't found yet the specific kilns.     

Tree-ring chronologies for the 6th to 16th centuries for oaks of southern and eastern England

The background to the problem of providing useful oak chronologies for the variable environmental conditions that apply in southern and eastern England is outlined. The reference chronologies published here embrace three new principles. Firstly, the samples, nearly 300, on which they are based are almost entirely of boards or planks that are of radial section (from oaks aged on average about 250 years) that form part of panel paintings or chests. Secondly, to take account of the differences in the growth pattern with the vigour of growth, separate chronologies for sequences of different ring-width have been formed. Thirdly, on account of the difficulties in extending, with the samples available, an English chronology by the method of overlapping, eight separate chronologies, each about 300 years long, have been created. Matching has been based on German methods, i.e. computer comparisons (with more than one reference chronology) supported by visual comparison of charts. Agreement values in about half a million positions were calculated.These reference chronologies, expressed as ring-widths, are suitable for application to oaks that have grown within a region of considerable size that covers both sides of the North Sea. For panels used as a support for paintings of the 15th and 16th centuries, they have dated 85% of 130 English (London area) ones and about the same percentage of 25 Flemish ones. Rather earlier, sequences for oak boards used in places as far apart as York, Norwich, Oxford and Winchester have been matched. In the 10th to 12th centuries, the ring-width chronology derived for the London area shows good agreement with those for the hilly regions of Germany and that for Schleswig, as well as dating floor planks from Viking houses in York. A floating chronology, 322 years long, dataed to the 6th to 9th centuries by several radiocarbon analyses, has been formed from long sequences of rings from timbers excavated at Old Windsor and Portchester: this has matched material from Southampton and is linked with a mean curve for the well at North Elmham (Norfolk) and the strakes of the Graveney ship.     

COMPOSITIONAL CHARACTERIZATION OF FRENCH LIMESTONE: A NEW TOOL FOR ART HISTORIANS*

Limestone from quarries known to medieval craftsmen and from the monuments they built and embellished, as well as from carvings now in museum collections, has been characterized by neutron activation analysis. Specimens from 38 quarries in the Lutetian and Jurassic limestone formations of France and from sculptures in American and French museums have been tested, and the results have been compiled in a data base to which art historians may refer when attempting to determine provenance for sculptures. Multivariate statistical analysis of concentration data shows stone from a particular quarry in the Paris basin to be compositionally homogeneous and distinguishable from other quarries in the same formation. The same approach to data related to quarries near the Burgundian abbey of Cluny finds general agreement between classifications based on compositional and on petrographic data, but the number of samples available for analysis at the time of writing was insufficient to achieve the finer distinctions reported for the Paris basin.     

The Faragola Ceramic Collection: Ceramic Production,Consumption and Exchange in Seventh‐Century Apulia

A collection of 30 ceramic samples, 16 of coarse wares and 14 of fine painted wares, have been investigated by optical microscopy, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, inductively coupled plasma mass spectrometry and neutron activation analysis. Further samples of clayey sediments, both locally outcropping and found within the settling tank, have been submitted to the same analytical techniques for comparison with the ceramic collection. The results demonstrated that local clayey sediments were used as received for the production of coarse wares. The same raw materials were sieved and/or refined by decantation for the production of fine painted wares, which, in fact, provided results that were perfectly comparable with those for the clayey raw materials found within the settling tank. The Faragola productions were distinguished from the neighbouring Apulian productions according to petrographic features (the presence of leucite‐bearing volcanic rocks and Mn‐rich wads) and their bulk chemical composition.     

Scurvy in adults and youngsters: the Dutch experience. A review of the history and pathology of a disregarded disease

Prior to the Dutch maritime expansion of the 17th and 18th centuries, scurvy was known in the Low Countries as an endemic disease. From the end of the 16th century the disease started to draw much more attention due to increasing long sea journeys of sailors. Already in the Dutch medical literature of the 16th century, a strong relation was expressed between the prolonged taking of foodstuffs of poor quality and the risk of contracting scurvy. Although from that time, many Dutch physicians recommended oranges, scurvy grass and brook‐lime, it took 200 years before inadequate therapy on the fleet was replaced by systematic prevention. Why did the old time effective recommendations for the therapy of scurvy stay inadequate for mariners? To understand, maritime and medical history were unfolded and evaluated with respect to palaeopathological findings reported for 39 cases of active scurvy and one case of healed scurvy. The palaeopathology of scurvy in adults and still growing youngsters was investigated from the remains of 50 Dutch whalers who had been buried during the 17th and 18th centuries on an island of the Spitsbergen Archipelago. Conforming the clinical literature, the original haematomas from scurvy were found as a black staining at the tips of dental roots. In the weight‐bearing bones of the lower extremities large black stains were positioned bilaterally around endofractures of the metaphyses, bilaterally on joint surfaces and bilaterally at epiphyseal discs of youngsters. In the non‐weight‐bearing bones they were often found unilaterally, such as at insertions of muscles. Immunoenzymatic staining of microscopic sections proved that the black stains were from remnants of denatured haemoglobin. No microscopic bone repair activities had happened. In a case of healed scurvy it could even be demonstrated how many times the recovery process had taken place from the layers of appositional bone which had replaced the original subperiosteal haematomas.

Ultramicroscopic investigation of the preservation status of hair collected from a full‐term,intrauterine baby mummy of the Joseon Dynasty,Korea

Our previous studies on the ultramicroscopic structure of mummy hair from Joseon Dynasty (1392–1910) tombs sealed with a lime‐soil mixture barrier (LSMB) have provided initial, basic information on their preservation status. Numerous additional cases of various conditions are required in order to provide data sufficient for establishing Korean mummy preservation patterns on a firm basis, however, and so we performed electron microscopic studies on hair taken from a full‐term, intrauterine baby mummy found in Paju, Korea. The baby mummy was found within the uterus of a 16th‐century mummified woman aged 20–30 years old. Since the labour and delivery stage for this case was 2, and the uterus was found to be ruptured, the cause of death of both the mother and the baby was likely to have been hypovolemic shock occurring during labour. In scanning electron microscopic (SEM) and transmission electron microscopic (TEM) studies, we found that the surface of the hair of the baby mummy was coated with crystalline substances, mainly on the side facing the vaginal orifice. We also observed well‐preserved cuticle, cortex and medullar layers, completely preserved cuticle‐layer scales, as well as macrofibrils and melanin granules evenly spread within the cuticle and cortex layers. Because studies on infant or subadult mummies are very few, and since they have focused mainly on the palaeopathological aspects of those mummies, the preservation pattern of the hair of a full‐term baby mummy could contribute significantly to our knowledge of mummies from around the world.

STEATITE SOURCE CHARACTERIZATION IN EASTERN NORTH AMERICA: NEW RESULTS USING INSTRUMENTAL NEUTRON ACTIVATION ANALYSIS*

Doubts have recently been cast on the ability to characterize steatite sources using rare earth elements (REEs). By increasing the number of samples and elements examined using instrumental neutron activation analysis (INAA) and multivariate statistics, this study shows that, with unhomogenized samples, transition metals, not REEs, make the greatest contribution in characterizing steatite sources in the Middle Atlantic region of eastern North America. Preliminary results suggest that INAA has the potential to assign provenance to steatite artefacts, at least at a regional level.     

The distribution and sources of archaeological pitchstone in Britain

Pitchstone is a glassy volcanic rock, distinguishable from obsidian by having a higher water content. It forms lava flows and minor intrusions at several centres within the British Tertiary Volcanic Province (BTVP) in the west of Scotland and Ireland. Pitchstone artifacts and waste pieces have been recorded from 101 archaeological localities in Scotland and northern England, ranging in time from possibly Mesolithic to Bronze Age. To characterize the sources, 17 pitchstone samples from 11 sources within the BTVP were analysed for major elements by energy-dispersive X-ray fluorescence (EDXRF), and for trace elements by instrumental neutron activation analysis (INAA). 28 pitchstone pieces from 22 archaeological sites were analysed, mainly non-destructively, by INAA and interpreted as having originated from Arran sources. The Arran sources are divided into four petrographic types; the Corrygills, Tormore, Glen Shurig and Glen Cloy Types. Petrographic study of 15 archaeological samples indicated that three were of Corrygills type and two were of Tormore type. The remainder were less confidently attributed to the petrographic types distinguished. Arran pitchstone is found as far as 300 km from the Arran sources, at the chambered tomb of Ord North in Highland.     

Bronze alloy production during the Iron Age of Luristan: a multianalytical study on recently discovered bronze objects

Application of bronze alloy to produce artistic and religious artefacts was commonplace during the Iron Age in western Iran (1500–550 BC). These bronze artefacts are the so-called Luristan bronzes and have been found often from excavated graves and sanctuaries. The aim of this paper is to study on alloy composition and manufacturing process in some recently excavated objects from the Iron Age cemetery of Baba Jilan, northern Luristan. For this purpose, some objects were analysed by quantitative ICP-MS as well as microscopic studies by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDS) and metallography methods. Also, some comparisons were carried out between Baba Jilan and other analysed bronze objects from Luristan in order to identify the metalworking process in bronze objects from the Iron Age of western Iran. The results showed that all Baba Jilan samples are made of binary copper-tin alloy. Tin content was variable in the composition of the samples. The variety of tin constituents proved that alloying has been performed by an uncontrolled process to produce bronze. The microscopic studies also showed that the manufacturing operations are similar in the Luristan bronzes. It was carried out to identify probable similarities in the bronze alloy production in the Iron Age of the Luristan region.     

The Structure and Chemical Composition of Wall Paintings From Islamic and Christian Times in the Seville Alcazar

Wall paintings from the Islamic epoch (10th to 12th centuries) and the Christian monarchy (14th to 16th centuries) have been recovered in discarded materials and on walls after reconstruction works in the Seville Alcazar. These paintings have spent centuries underground or under a plaster coat. Portable X‐ray fluorescence (XRF) and combined XRF/X‐ray diffraction (XRD) were employed in situ, as well as scanning electron microscopy (SEM–EDX), grazing angle incidence XRD and micro‐Raman spectroscopy, on cross‐section samples to fully characterize the materials in the wall paintings. Using these methods, the fresco technique was demonstrated, and many kinds of pigments were identified in accordance with the various periods of the history of the Alcazar, thus assessing the authenticity of all the wall paintings studied here.     

NEUTRON ACTIVATION ANALYSIS OF ANCIENT BURMESE SILVER COINS WITH A LOW FLUX AMERICIUM/BERYLLIUM NEUTRON SOURCE

Nondestructive neutron activation analysis is by now a well-established technique for the analysis of ancient silver coins. The high activation cross-section of silver for thermal neutrons makes it possible to also use this method with the low neutron fluxes available from an isotopic neutron source. In this case due consideration must be given to minimize the self-shielding effect which is encountered with coins above a few tenths of a millimetre thickness. A simple method for the determination of the silver, copper and gold content in silver coins based on the self-shielding properties of silver alloys of different fineness is described. The method has been found to be useful for the quick routine assay of silver coins for the purpose of their classification. Seventeen ancient Burmese silver coins from three different cultural periods of Burma, and two British coins for comparison have been analyzed by this method.     

AN INVESTIGATION OF THE PROVENANCE OF THE ROMAN AMPHORA CARGO FROM THE PLEMMIRIO B SHIPWRECK

Eighty-six Roman amphora sherds from the Plemmirio B shipwreck, off Sicily, have been analysed by neutron activation analysis. A large group representative of the amphora cargo, mainly of forms Africana 1 and Africana 2A (from the area of modern Tunisia), was subsequently defined. No differences between Africana 1 and Africana 2A samples were observed, thus implying a similar origin for both forms. The provenance of this cargo group was then investigated by comparison with a Roman amphora kiln data base. After elimination of the more mobile elements it was shown that the cargo amphorae were more likely to have been manufactured at kilns around Sullecthum rather than Leptis Minor. The analytical conclusions are thoroughly consistent with the known archaeological information.     

DISCRIMINATING SOURCES OF MEDITERRANEAN MARBLES: A PATTERN RECOGNITION APPROACH

A computer-based pattern recognition procedure has been applied to trace element data obtained from marble samples of different Mediterranean quarries. Nineteen elements, mostly hydromagmatic and rare earth elements were first determined by neutron activation analysis. These elemental concentrations are then used as the data for further multivariate analysis. The results indicate significant differences in chemical patterns of the marble sources.
