INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECTROSCOPY ANALYSES OF ROMAN MILITARY COPPER-ALLOY ARTEFACTS FROM THE EXCAVATIONS AT MASADA,ISRAEL*

A selection of Roman military fittings and associated copper-alloy artefacts was analysed by inductively coupled plasma-atomic emission spectroscopy. The method used was a variant on those previously published and gives very good precision and accuracy. The Roman metalwork analysed conforms extremely well to similar artefacts analysed from, contemporaneous European sites and suggests, despite the strongly ‘local’ nature of the Judaean legions, a considerable uniformity of alloying practice within the Roman army during the first century AD.     

A NEW SETTING FOR THE NORTHERN BORDER OF THE VENETI: METALLIC FINDS FROM THE VENETIC SITE OF MONTE CALVARIO,AURONZO DI CADORE*

In 2000 several bronze and lead objects were discovered at the Venetic‐Roman site (200 bc –ad 200) of Monte Calvario di Auronzo, in the Italian eastern Alps. They were mostly finished artefacts plus semi‐worked products. Analysis included SEM–EDS, EMPA, XRPD, TMS and AMS spectrometry. The compositional results of the finished artefacts suggest that the choice of the alloy had been made according to the decorative techniques to be used. A semi‐worked high‐leaded bronze object indicates the existence of a metallurgical production of cast artefacts at the site. TMS analyses of a lead ingot exclude local provenance, proving the existence of important trade routes.     

THE OPAQUE RED GLASS OF CELTIC ENAMELS FROM CONTINENTAL EUROPE

Opaque red glass was used in the Celtic world for enamels and inlays. Forty artefacts, of various dates and found in various places, have been sampled and studied. They all belong to the same type, a soda-lime-silica high lead glass coloured by crystals of cuprous oxide. There is only one subgroup: glass lumps from the Mont-Beuvray oppidum contain manganese, less iron, and less lead. This change could be the result of Roman influence. Although most of these glasses form a surprisingly homogeneous group, no conclusions as to their origin can be inferred from our present knowledge.     

Elevated lead exposure in Roman occupants of Londinium: New evidence from the archaeological record

The evolution of metallurgical practices over several millennia has resulted in human exposures to a diverse variety of toxic elements. These exposures were not just confined to the metalworkers, but in many cases broadly impacted the larger community and society. The role of lead in Roman civilization is particularly fascinating, where the available evidence of lead use in a myriad of applications by Roman civilization suggests the potential for elevated exposures. The present paper addresses the hypothesis that because of these practices, Roman occupants of ancient Londinium (43–410 ad ) were exposed to levels of lead that far exceeded exposures in the preceding populations of Iron Age Britain (700 bc –43 ad ). The elemental content and stable lead and strontium isotopic signatures of 30 femora from three Londinium cemeteries and radiocarbon-dated representative burials were examined and the results then compared with 70 femora dating to the pre-Roman Iron Age from the well-known Iron Age hillfort of Danebury, Hampshire, and from three cemeteries in East Yorkshire. Extensive efforts were directed at the minimization of sediment and soil contamination, the assessment of contamination from burial artefacts and a careful review of the burial context of specimens. Data for lead and 20 additional trace and major elements were obtained by magnetic sector inductively coupled plasma mass spectrometry (ICPMS), after acid dissolution of pre-cleaned bone cores. Lead isotope ratios in the bone core digests (and burial soils) were measured by multi-collector ICPMS. It was found that concentrations of lead in the Roman/Londinium-era femora were > 70-fold greater than those from pre-Roman populations. This was confirmed by femoral data obtained from the analysis of a pre-Roman burial from the early first century bc found adjacent to the Southern Cemetery. Several major and trace element metrics for diagenesis demonstrate that levels of lead in the bone are robust indicators of human exposure during life. Lead isotope data for the Roman population are consistent with previously identified widespread lead pollution. The pre-Roman populations contain lead isotopic compositions consistent with highly localized, minor sources of lead. Together, these data provide unequivocal confirmation that the Romans in Londinium were exposed to elevated lead levels. Elevated blood lead levels would have resulted, negatively affecting their health and possibly contributing to declining birth rates.     

TRACING THE RESOURCES OF IRON WORKING AT ANCIENT SAGALASSOS (SOUTH‐WEST TURKEY): A COMBINED LEAD AND STRONTIUM ISOTOPE STUDY ON IRON ARTEFACTS AND ORES*

Lead and strontium isotope analyses were performed by thermal ionization mass spectrometry (TIMS) on Roman to Byzantine iron artefacts and iron ores from the territory of ancient Sagalassos (south‐west Turkey), to evaluate Pb and Sr isotopes for provenance determination of ores for local iron production. It can be demonstrated that for early Roman artefacts and hematite iron ore processed in early Roman times from Sagalassos proper, as well as for magnetite placer sands and early Byzantine raw iron from the territory of the city, Sr isotopes are much less ambiguous than Pb isotopes in providing clearly coherent signatures for ore and related iron objects. Late Roman iron objects were produced from iron ores that as yet remain unidentified. Early Byzantine iron artefacts display more scatter in both their Pb and Sr isotope signatures, indicating that many different ore sources may have been used. Our study demonstrates that iron objects can be precisely analysed for their Sr isotopic composition, which, compared to Pb isotopes, appears to be a much more powerful tool for distinguishing between chronological groups and determining the provenance of raw materials.     

Geochemical provenance analyses of Roman lava millstones north of the Alps: a study of their distribution and implications for the beginning of Roman lava quarrying in the Eifel region (Germany)

In Roman times, rotary querns and different types of millstones, driven either by horse-capstan or water power, were produced in the lava quarries of the quaternary volcanic Eifel region and exported to many parts of the Empire. The geographic distribution of Roman lava millstones from the Eifel region provides important information about trade patterns and, in cases of well dated millstones, also allows an estimate as to when the Roman lava quarrying in the Eifel region began. Sixty-two millstones from Germany, France and Austria were sampled and analyzed for major and trace elements by X-ray fluorescence. To determine their provenance, the millstone data was evaluated by a combination of geochemical discrimination and cluster and discriminant analyses using an extensive and detailed database of all Roman lava quarries in the Eifel region. An Eifel provenance could be confirmed for forty-four artefacts and, furthermore, determined down to the exact lava flow. The affiliation of the other artefacts to other possible regions where millstones of comparable lava were extracted was carried out on the basis of geochemical data from the literature. However, because of insufficient data, only assumptions about the regional provenance can be made. The origins of the other finds are assumed to be the Vogelsberg region, the Massif Central, Orvieto, and, possibly, the Pannonian Basin. A preliminary map of the distribution of Eifel millstones in Roman times based on these data is presented; the beginning of Roman lava quarrying can be constrained to 8–7 BC.     

On Some Remains of the Work of William of Wykham,at Windsor Castle

Scholarly opinion on the character and timing of the end of Roman Britain remains deeply divided. The evidence presented by those favouring a ‘long chronology’ is seriously flawed. ‘Continuity’ or ‘survival’ of Roman Britain is claimed because early medieval activity is attested on some former Roman sites and some early medieval artefacts are of Roman type. But Roman Britain was part of a ‘world system’ with a distinctive and rich archaeological assemblage, and once terms are properly defined and material analysed quantitatively, the argument for fifth-century continuity collapses. The archaeological evidence shows that after a long process of decline beginning in the third century, Roman Britain had ended by c. A.D. 400.     

A Late Roman Quay in the River Meuse near Cuijk,Netherlands

The detection of the waterlogged remains of massive oak foundation piles in the river Meuse near the Dutch city of Cuijk led to the discovery of a unique Late Roman site. The piles, driven into the river‐bed, had protected vast layers of organic material containing all kind of artefacts against erosion by the river. Increased erosion during recent decades has uncovered much of the structure and artefacts, which have been meticulously recorded and collected by divers of the Dutch foundation Mergor in Mosam. Analysis of all data retrieved over the past 20 years has provided much information about the environment and life in Ceuclum, the Roman city of Cuijk.     

Evidence for Indo-Roman Trade from Bet Dwarka Waters, West Coast of India

India had a very active maritime trade contact with the Roman world between the 4th century BC and the 4th century AD. In this context recent finds of stone anchors, potsherds, lead anchors and a lead ingot from 5 to 8 m water-depth near Bet Dwarka jetty is significant. The sherds include amphoras, jars, bowls and lids. Archaeological finds along the Indian coast and comparison between amphoras from Bet Dwarka and the Mediterranean suggest that the artefacts from Bet Dwarka may be datable to between the 1st century BC and the 2nd century AD. The numbers of stone anchors suggests that this was an ancient anchorage.

A MULTIDISCIPLINARY APPROACH TO THE CHARACTERIZATION OF ROMAN GRAVESTONES FROM AQUILEIA (UDINE,ITALY)*

The results of an archaeometric study on gravestone production in Aquileia (northeastern Italy) during Roman Republican times are reported here. The artefacts are made of limestone, quarried from the sedimentary sequence of the Trieste Karst (Carnican Alps, northeastern Italy), as testified by historical sources which refer to the ‘Roman Quarry’ at Aurisina. The rock types used for the gravestones are petrographically, geochemically and geochronologically homogeneous, and display similar faunal assemblages. In addition, their age is restricted to the Santonian – Lower Campanian. Comparisons between archaeological finds and rock specimens from various active and inactive quarries in this area suggest that quarrying during Roman Republican times was limited to a specific stratigraphic horizon of the sedimentary sequence, corresponding to the higher part of the ‘Roman Quarry’.     

A long-distance copper alloy trade to the North Eastern Baltic during the late pre-Roman and Roman Iron Age (250 BCE–450 CE) explored with lead isotope MC-ICP-MS

The North Eastern Baltic has no copper resources of its own, meaning that Cu alloy was imported either as raw material or as finished objects. The north-eastern coastline of Estonia during the late pre-Roman and Roman Iron Age was connected to the south by sea to the long-distance ‘amber’ trade route and to the east by Russian river systems. This study quantitatively assesses the direction of the Cu alloy supply in the region before and after brass enters circulation at the beginning of the Roman Iron Age. After an initial portable X-ray fluorescence (pXRF) survey, 18 objects were chosen for Pb isotope analysis. This isotope analysis resolved a group of nine brass artefacts from the Roman Iron Age amongst a ‘melting pot’ of other Cu alloys. The similarity between the isotope ratios found in the Roman world suggests the presence of the same ‘melting pot’ in the North Eastern Baltic, possibly created by a large amount of Roman Cu alloy being traded north. No evidence for Cu alloy from Scandinavia or the Ural Mountains could be found. The hypothesis from this small study is that the Cu alloy entering Estonia was dominated by metal from Southern Europe from the late pre-Roman Iron Age and the Roman period.     

First results of metallographic analysis and absolute dating of iron finds from Nowe Brzesko,site 26, Proszowice District

This paper presents the results of analyses of metal artefacts discovered at a multiphase site in Nowe Brzesko, Małopolskie Voivodeship, Poland. Fieldwalking prospection led to the discovery of steely iron objects, ploughed out on the site among other numerous archeological finds. A prospecting sondage yielded more corroded metal artefacts, identified mainly as agricultural tools (e.g. sickles, scythes). These chronologically nondistinctive artefacts could be assigned to the third to fourth century AD using radiocarbon dating, complemented by metallurgical analysis. The results open up new research perspectives on the economy and society of the Przeworsk culture in the Late Roman period.     

THE COMPLEMENTARY USE OF NEUTRONS AND X‐RAYS FOR THE NON‐DESTRUCTIVE INVESTIGATION OF ARCHAEOLOGICAL OBJECTS FROM SWISS COLLECTIONS*

This paper shows the possibilities offered by the combined use of non‐destructive neutron and X‐ray beams in archaeological research on metallic finds. The following five artefacts from Swiss excavations were submitted to investigation, each with dedicated aims: a Roman sword, a Roman dagger, an Iron Age bucket, Iron Age spearheads and a Roman finger ring. The images obtained with both methods—neutrons and X‐rays—are discussed in length in this paper. The investigations took place at the Paul Scherrer Institute and the archaeologists who studied the objects come from the Universities of Lausanne and Zurich.     

A Lead Danubian Rider Plaque

A small lead relief in the hands of a British collector can be identified as belonging to the Danubian Rider cult, so called because the names of deities associated with this Roman-period religion are unknown and artefacts are identified by a pair of horsemen flanking a female deity and accompanied by other distinctive iconographic elements. This example, of unknown origin but probably discovered in east-central Europe, shows the typical composition. Other examples cast from the same mould are known. Although there is little hard fact about this cult and almost nothing written has survived, it is possible to suggest interpretations for much of the imagery by reference to contemporaneous religious activity within the Roman Empire during the second and third centuries AD.     

A Hellenistic/Early Roman Shipwreck Assemblage off Ashkelon, Israel

Underwater surveys at Ashkelon during 1998 exposed a Hellenistic/Roman shipwreck. The ship, c .15–25 m long, sank in the 1st or 2nd century BC, and its remains include iron anchors, lead sheathing, copper nails, assorted metal artefacts, and shipwright's unused nails. Bronze vessels found—oil-lamp, shovel and ladles—could have functioned in cult rites. Weights and balance-scale parts demonstrate commercial activity. Fishing-net sinkers indicate involvement in fishing. This paper raises important points regarding the risk to shipwrecks on the Israeli coast from environmental and human interference, and suggests that Ashkelon never had a built-up port.

Combined Pb–Sr isotopic analysis in provenancing late Roman iron raw materials in the territory of Sagalassos (SW Turkey)

In early Roman times, iron was likely supplied to the city of Sagalassos through the smelting of close-by hematite ores. In the early Byzantine period, magnetite–titanite placer sands in some instances could have been exploited for its iron. For the intermediate late Roman period, however, the source of the locally used iron was unknown. Pb and Sr isotopic analyses of iron ores from the area of Camoluk, just south of the territory of Sagalassos, and of late Roman iron artefacts from the antique city itself, reveal a very close resemblance. This makes the use of the Camoluk ores to supply Sagalassos with raw iron in the late Roman period likely. It is also shown that combined Pb and Sr isotopic analyses provides a powerful tool to distinguish chronological groups of iron provenance and a technique that can determine the nature and source of iron raw materials used.     

A study of the Roman iron bars of Saintes-Maries-de-la-Mer (Bouches-du-Rhône,France). A proposal for a comprehensive metallographic approach

The aim of this paper is to contribute to the understanding of the organisation of the manufacture and circulation of iron bars and the possible bar standardisation of a given set of artefacts in order to throw more light on commercial patterns during Antiquity. A set of 48 iron based metal bars originating from the Roman shipwrecks at Les Saintes-Maries-de-la-Mer (France) has been studied using comprehensive metallographic observations, ranging from macroscopic to microscopic scales and slag inclusion (SI) analyses. A comparison of the results allows one to distinguish different metal qualities (inclusions, pores, welding, carbon content) that may be linked to morphological types, which shows the possible standardisation of this set of artefacts. Moreover, SI analyses allow distinguishing various origins for the Primary Pieces of Metal, thereby throwing light on a specific organisation of the iron bar production line during the late Roman period.
