The Determination of Lead Isotope Ratios by Multiple Collector Icp‐Ms: A Case Study of Early Bronze Age Artefacts and their Possible Relation With Ore Deposits of the Erzgebirge*

Lead isotope analyses of Early Bronze Age metal artefacts from the Aunjetitz (Ún?tice) culture in central Germany and Bohemia were determined in order to find out whether they could be related to ore sources of the Erzgebirge. Historical mining began only in the 12th century ad , but despite the lack of convincing field evidence it has frequently been suspected that this region was already being exploited in prehistoric times. For the determination of the lead isotope ratios, the new technique of multiple collector inductively coupled plasma mass spectrometry (MC‐ICP‐MS) was employed, which combines relatively easy sample preparation with highly precise and accurate measurements. The results show that there is still no evidence for prehistoric mining in the Erzgebirge, but the Rammelsberg deposit in the Harz Mountains might have supplied some of the copper. Mining of stream tin in the Erzgebirge remains a possibility, but no positive evidence can be extracted from the data.     

TIN ISOTOPY—A NEW METHOD FOR SOLVING OLD QUESTIONS

Tin was a vital commodity in times past. In central Europe, the earliest finds of tin‐bronze date to about 2200 bc , while in Greece they are c. 400–500 years earlier. While there is evidence for prehistoric copper mining—for example, in the Alps or mainland Greece, among other places—the provenance of the contemporary tin is still an unsolved problem. This work deals with a new approach for tracing the ancient tin via tin isotope signatures. The tin isotope ratios of 50 tin ores from the Erzgebirge region (D) and 30 tin ores from Cornwall (GB) were measured by MC–ICP–MS. Most ore deposits were found to be quite homogeneous regarding their tin isotope composition, but significant differences were observed between several deposits. This fact may be used to distinguish different tin deposits and thus form the basis for the investigation of the provenance of ancient tin that has been sought for more than a century. Furthermore, the tin‐isotope ratio of the ‘Himmelsscheibe von Nebra’ will be presented: the value fits well with the bulk of investigated tin ores from Cornwall.     

THERMOLUMINESCENCE DATING OF A CRUCIBLE FRAGMENT FROM AN EARLY TIN PROCESSING SITE IN TURKEY

Archaeological exploration in the Taurus mountains at Göltepe in south-central Turkey has uncovered a site indicating the presence of extensive tin ore mining and smelling operations The most recent find of smelting crucible fragments allowed for a thermoluminescence-hased age determination spanning a late fifth to early third millennium BC date. This result is consistent with a number of radiocarbon dates derived for charcoal also found at the site. The importance of this site relates to the possible tin production and subsequent trade with southwestern Asia which would have provided this otherwise scarce ingredient to bronze technology in that area. This date is directly for crucible material and thus confirms the antiquity of tin smelting at Göltepe.     

A NIGERIAN TIN TRADE IN ANTIQUITY?

Summary: Eighteen hundred miles due south of Carthage, across the Sahara, lies one of the richest sources of tin in the modern world. Here, the Bauchi region of northern Nigeria contains extensive deposits of alluvial cassiterite. This is a singularly important geological feature, since stream tin, as it is more commonly known, was the only tin ore profitably available in antiquity (Muhly, 1973: 248). This paper, as the title implies, is concerned with the question of whether Carthage received tin from this particular area of West Africa.¹ There are certain considerations that suggest such a possibility, but the evidence is tantalizingly nebulous, making answers both inconclusive and speculative.     

TIN AND PREHISTORIC MINING IN THE ERZGEBIRGE (ORE MOUNTAINS): SOME NEW EVIDENCE

Summary. A number of settlements and other traces of occupation have been identified in the mountainous areas near to tin and copper deposits in the Erzgebirge, and some of them excavated. The newly collected evidence seems to suggest that many small sources of metals, both tin and copper, were exploited, the former metal by washing from the river and creek beds. Though these sources were more modest than the British and Spanish tin supply, they seem to have served the Bohemian and Saxon Bronze Age cultures well.     

ON THE COMPOSITION AND PROVENANCE OF METAL ARTEFACTS FROM POLIOCHNI ON LEMNOS

Summary. The majority of the well-stratified Early Bronze Age metal objects from Poliochni, with the exclusion of one hoard find, was analyzed for their chemical and lead isotope composition. The results show that a major change occurred in the metal used at Poliochni during periods contemporary with Troy I and Troy II. Unalloyed or arsenical copper with relatively high lead contents during the earliest two periods 'azzurro' and 'verde' is gradually replaced and supplemented by tin bronze which, during period 'giallo', i.e., by the end of Troy II, becomes the dominant metal type. Lead isotope abundance ratios in the earlier artefacts are consistent with a derivation of the metal from regional ore sources but the trace element abundance pattern is not. Concurrent with the appearance of tin bronzes is an increase in the diversity of ore deposits exploited; for about one third of the artefacts from period 'giallo' there is as yet no matching ore source in all Anatolia and the Eastern Mediterranean. It is argued that the tin bronzes have been imported as such but that the lead isotope signature does not provide any direct clues to the origin of the tin.     

No laughing matter: Antiquity in Greek political cartoons

Abstract

This article discusses the deployment of antiquity in Greek political cartoons covering the period from 1974 to the present. It argues that in order to function cartoons must rely on preconceptions and widespread popular beliefs; they thus can be seen as an important source for the investigation of popular stereotypes of antiquity. Moreover they engage actively in the construction of visual memory through the visualization of abstract notions. Greek political cartoons are shown often to use the most easily recognisable themes from antiquity and rely on its moral authority (stemming from the position of antiquity in the national imagination and public discourse) in order to critique and ridicule policies and politicians. The authority of antiquity itself, however, is rarely questioned. Cartoons and antiquity are not involved in a simple relationship of representation; theirs is rather a relationship of engagement, a relationship of veneration and submission which constructs a reality where the dividing lines between the past and the present are blurred, a reality which is structured by the powerful symbolic order of national memory.     

First comprehensive peat depositional records for tin,lead and copper associated with the antiquity of Europe's largest cassiterite deposits

Tin, as a constituent of bronze, was central to the technological development of early societies, but cassiterite (SnO₂) deposits were scarce and located distantly from the centres of Mediterranean civilizations. As Britain had the largest workable ore deposits in the ancient Western world, this has led to much historical speculation and myth regarding the long-distance trading of tin from the Bronze Age onwards. Here we establish the first detailed chronology for tin, along with lead and copper deposition, into undisturbed ombrotrophic (rain-fed) peat bogs located at Bodmin Moor and Dartmoor in the centre of the British tin ore fields. Sustained elevated tin deposition is demonstrated clearly, with peaks occurring at 100–400 and 700–1000 calendar years AD – contemporaneous with the Roman and Anglo-Saxon periods respectively. While pre-Roman Iron Age tin exploitation undoubtedly took place, it was on a scale that did not result in convincingly enhanced deposition of the metal. The deposition of lead in the peat record provides evidence of a pre-Roman metal-based economy in southwest Britain. Emerging in the 4th century BC, this was centred on copper and lead ore processing that expanded exponentially and then collapsed upon Roman colonization during the 1st century AD.     

EARLY BRONZE AGE TIN PROCESSING AT KESTEL/GÖLTEPE,ANATOLIA

Chemical analysis of statistically significant numbers of samples including minerals, sediments, soil, host rock as well as powdered materials, crucible accretions and metal artefacts revealed information about the distribution of cassiterite at Kestel and the tin smelting processes that took place at Göltepe c. 2600 BC. Using the ancient technique of vanning for the isolation of tin ore (cassiterite), followed by assaying by blowpipe/charcoal block, as well as crucible smelting with a blowpipe, good tin metal suitable for alloying with copper to make bronze was obtained. There is every indication that tin was mined and smelted in the Early Bronze Age at the Kestel/Göltepe sites.     

EARLY BRONZE AGE TROJAN METAL SOURCES AND ANATOLIANS IN THE CYCLADES

Summary. New chemical analyses of EB II copper-alloy artefacts from Troy show that about seventy per cent are of high tin, low arsenic, bronze; the remaining Trojan objects are of arsenical copper but contain no more than 3 per cent of arsenic. Lead-isotope analyses suggest that at this time the Trojans made use of at least five different copper-ore deposits and that at least two of these were not in the immediate vicinity of Troy itself.
At this period tin bronze was unknown in the Early Helladic, Cycladic or Minoan cultures. Low-arsenic tin bronzes do however constitute sixty-nine per cent of the copper-alloy artefacts excavated at the fortified hilltop EC IIIA settlement at Kastri on Syros, but lead-isotope analyses show that the copper in these objects is derived from three different ore deposits which are different from those exploited by the early Cycladic peoples on Amorgos, Paros, Kythnos and Chalandriani on Syros. For Kastri the alloy types are closely similar to and the copper ore sources used are identical with those employed in Troy II; in addition there are good Anatolian parallels for some of the metal types occurring at Kastri. Taken together with evidence from the pottery, the architecture and the nature of the site it seems inescapable that Kastri was a short-lived settlement of Anatolians who lived, perhaps, in somewhat uneasy juxtaposition with their Cycladic neighbours. These Anatolians came most probably from Troy or the Troad since tin bronze was virtually unknown at this period elsewhere in Anatolia, and certainly not in Cilicia, except at the central Anatolian sites of Ahlatlibel, Alishar and Alaca Hüyük.     

Probing the provenance of archaeological glaze colorants: Polychrome faunal reliefs of the Ishtar Gate and the Processional Way of Babylon

The polychrome glazes from the Processional Way and the Ishtar Gate of Babylon are among the best preserved from antiquity. Yet, little is known about the logistical choices involved in their production. Variations in isotope ratios can be useful for complementing an archaeological investigation of potential geological sources of raw materials. Consistent with archaeological evidence and ancient texts on trade in metals, Turkish ore deposits are thus tentatively proposed as possible sources of the metal oxide colorants used for the investigated polychrome glazes of three Neo‐Babylonian faunal reliefs that are now part of the collection of the Ny Carlsberg Glyptotek, Copenhagen.     

The Medieval and Early Modern Cornish Stamping Mill

Abstract

The exhaustion of the richest alluvial tin deposits led to development of lode tin. Stamping mills were developed to crush the ore and although considerable archaeological and documentary work had been carried out in neighbouring Devon, little research had been undertaken in Cornwall. The excavation of two mills at Colliford, the survey of further examples at Retallack and an extensive search of documentary evidence has allowed an appraisal of this aspect of the early Cornish tin industry. Much work still remains, but now it is possible to be much more positive about the character of the surviving field evidence, the potential for excavation and the need to develop a research strategy.

Bear Imagery and Ritual in Northeast North America: An Update and Assessment of A. Irving Hallowell's Work

Abstract

Over seventy years ago, A. Irving Hallowell called attention to the widespread distribution of bear ceremonialism among boreal cultures of northern Eurasia and North America. He showed that reverence for the bear was governed primarily by sociopsychological factors of possible great antiquity. This study draws on Hallowell's insights and uses a holistic approach to interpret bear imagery and ritual found in archaeological contexts for northeastern North America. Various data demonstrate the antiquity and variability of bear ceremonialism including the communal feasting of bear brains, ritual use of skull masks, public display of skulls in elevated positions, various expressions of symbolism in art, ritual disposal of post-cranial remains, and widespread distribution of bear clans with their associated rituals and leadership roles. Cross-culturally, the bear may signify a dangerous predatory animal opposed to humans while simultaneously looking and behaving like a person, thus representing a source of power as an other-than-human being.     

PETROGRAPHIC AND ISOTOPIC CHARACTERIZATION OF THE MARBLE OF THE ISLAND OF TINOS (GREECE)*

Most outcrops of good‐quality crystalline marble in Mediterranean countries were exploited in Greek and Roman times. Hence, a wide variety of marble is now found in archaeological excavations. The precise determination of the provenance of a marble object is of great archaeological importance, and is now mostly obtained by coupling the petrographic study of a thin section with the analysis of the C and O stable isotopes, or by stereomicroscopy and EPR. The existing databases are considerable but still insufficient, because our knowledge about and study of ancient Mediterranean quarries remain incomplete. The contribution of this research is to add new petrographic and isotopic data on small quarries on the Greek island of Tinos that were exploited in antiquity. This marble belongs to the same geological horizon; it is quite pure, sometimes dolomitic and characterized by a low‐T, high‐P metamorphism that produced a limited recrystallization (MGS varying from 0.64 to 2.50 mm) on marine limestone protoliths. The petrographic features are quite distinctive: the fabric is strongly lineated and often stressed; and the accessory minerals are ubiquitary quartz, ore minerals, graphite and muscovite. As far as the isotopic data are concerned, δ¹³C_PDB varies from 1.1 to 2.7, and δ¹⁸O_PDB from ?1.7 to ?11.4. Both the features and the data have been compared with those of similar marbles used in antiquity, showing that their combination mirrors the fingerprint of the Tinos marble.     

The Mineralogy of Bronze Age Copper Ores from the British Isles: Implications for the Composition of Early Metalwork

Numerous analytical studies during the latter half of this century have contributed to the compilation of a large compositional database of Early to Middle Bronze Age copper-based artefacts revealing distinctive impurity patterns which appear to change over time. However, attempts to relate these data to copper ore sources proved problematic in the absence of firm evidence for the location of prehistoric copper mines. Over the last fifteen years this situation has changed dramatically with the discovery of numerous Early and Middle Bronze Age copper mines in England and Wales. This study is the first attempt at a comprehensive mineralogical survey of the principal mines investigated to date in order to define the likely composition of the copper ores as mined in antiquity for comparison with the artefact database. The study suggests that the majority of these mines can only have produced essentially pure copper. Only one mine, Ross Island, is likely to have produced copper with a significant level of impurities. The relative purity of the known ore sources is contrasted with significant levels of various metallic impurities among the analysed artefacts, leading to the conclusion that metal circulation and mixing may have been more extensive than previously thought even during the earliest part of the Bronze Age.     

A PRELIMINARY PETROGRAPHIC ANALYSIS OF CYPRIOT WHITE SLIP II WARE*

Samples of Late Bronze Age White Slip II ware from Cyprus were analysed using optical and scanning electron microscopy in conjunction with energy and wavelength dispersive analyse The slip has a novel granular nature and the coarser aggregates are impressed into the outer surface of the body, indicating that it was applied to a moist surface before the vessels were fired. It has a consistent mineral assemblage (Mg‐chlorite + illite‐smectite + sphene + anatase/rutile ± albite) which is very similar to that of hydrothermally altered zones associated with copper orebodies in the Troodos Massif which were mined in antiquity Our analysis suggests that the raw material for the slip was not found at the ground surface, because the alteration assemblage is unaffected by oxidation and copper carbonate or iron staining. It may, therefore, be a by‐product of sub‐surface ore extraction     

The invention and uses of folk art in Germany: wooden toys from the Erzgebirge mountains

This article attempts to historicise the concept of “folk art” using the example of wooden toys from the Erzgebirge mountains to show that it was invented by cultural élites as a marketing concept at the beginning of the twentieth century in order to support a domestic industy caught in structural crisis.
