Chemical and mineralogical examination of metallurgical ceramics from a Late Bronze Age copper smelting site in Cyprus

For metallurgical processes in antiquity functional materials were required, which were sufficiently heat resistant. Commonly, ceramics were used for the production of furnaces, tuyères and crucibles. Because normal pottery usually could not withstand the extreme temperatures, which were needed for metallurgical operations, the ceramic production process had to be modified. An analytical case study will be presented on refractory ceramics from the Late Bronze Age copper smelting site Politiko-Phorades (Cyprus). Cyprus had a major role in copper production, starting from this period, and the selected site is the earliest primary smelting site discovered in Cyprus until now. Furnace and tuyère fragments were analysed chemically and mineralogically, in order to investigate ancient ceramic technology in view of heat resistance.     

Rethinking Middle Bronze Age Communities on Cyprus: “Egalitarian” and Isolated or Complex and Interconnected?

Current views of Cyprus during the Middle Bronze Age (or Middle Cypriot period) depict an island largely isolated from the wider eastern Mediterranean world and comprised largely if not exclusively of “egalitarian,” agropastoral communities. In this respect, its economy stands at odds with those of polities in other, nearby regions such as the Levant, or Crete in the Aegean. The publication of new excavations and new readings of legacy data necessitate modification of earlier views about Cyprus’s political economy during the Middle Bronze Age, prompting this review. We discuss at some length the island’s settlement and mortuary records, materials related to internal production, external exchange and connectivities, and the earliest of the much discussed but still enigmatic fortifications. We suggest that Middle Bronze Age communities are likely to have been significantly more complex, mobile, and interconnected than once envisaged and that the changes that mark the closing years of this period and the transition to the internationalism of Late Bronze Age Cyprus represent the culmination of an evolving series of internal developments and external interactions.

     

Bronze Age boundaries and social exchange in north-west Cyprus

Summary.   During the Late Bronze Age a number of towns engaged in copper production and overseas trade arose throughout the coastal regions of Cyprus. While some of these towns were located within a few kilometres of major ore deposits in the Troodos Mountains, others were situated much farther away, and presumably acquired their copper supplies through extensive networks of exchange. This paper addresses the question of how such networks may have been structured in north-western and north central Cyprus, within and adjacent to the research area of the Sydney Cyprus Survey Project. Based on our analyses of site locational factors, we propose the co-existence of at least two distinct networks of copper procurement and transport. Consideration of the finds from settlement and mortuary sites in the northern Troodos and Mesaoria plain suggests a pattern of hierarchical exchange relations between coastal and inland regions.     

Archaeobotanical inference of Bronze Age land use and land cover in the eastern Mediterranean

Charcoal and charred seeds at five Bronze Age archaeological sites discern ancient land use in the eastern Mediterranean. Seed frequencies of orchard crops, annual cereals and pulses, and wild or weedy plants are used to characterize plant utilization at different archaeological sites on the island of Cyprus, in the Rift Valley of Jordan, and in the Jabbul Plain and along the upper Euphrates River valley in Syria. Seed to charcoal ratios provide proxies to determine the relative usage of dung versus wood for fuel across the ancient Mediterranean landscape. Greater charcoal and lower charred seed values are interpreted to represent a wooded environment, while higher amounts of charred seeds and minimal wood charcoal suggest a much great use of dung as a fuel source. Interestingly, Politiko-Troullia (Cyprus, Cypriot archaeological sites are, by convention, named for the nearest modern village (Politiko), followed by an italicized toponym (Troullia) referring to the plot of land that incorporates the site) has the lowest seed to charcoal ratio, suggesting its residents primarily burned wood and that the landscape surrounding Troullia remained relatively wooded during the Bronze Age. In contrast, villagers at Tell el-Hayyat (Jordan) utilized a mixture of wood and dung, in contrast to Tell Abu en-Ni’aj (Jordan), and especially Umm el-Marra and Tell es-Sweyhat (Syria), where inhabitants relied solely on dung fuel. Comparative analysis and interpretation of seed and charcoal evidence thus illustrates the variety of fuel use strategies necessitated by the dynamic and diverse Bronze Age landscapes of the Eastern Mediterranean.     

LEAD ISOTOPE CHARACTERISTICS OF THE CYPRUS COPPER ORE DEPOSITS APPLIED TO PROVENANCE STUDIES OF COPPER OXHIDE INGOTS

Nearly 200 new lead isotope analyses of sulphidic and oxidized ores from 26 copper mines on Cyprus show that the mines from different geological regions group in five distinctive isotopic groups, each with a substructure, related to the geological history of the ore formation. Comparison of lead isotope compositions of Bronze Age artefacts with these data can in many cases reveal the actual mines from which the copper for particular artefacts was obtained. The particular case of the provenance of the copper for 78 Late Bronze Age copper ‘oxhide ingots’found in Cyprus, Crete, Greece, Sardinia, Turkey and Bulgaria is discussed. The data show that all oxhide ingots so far analysed, dating to the fourteenth century BC and later, were made of copper consistent isotopically with only one mining region in the geographical north of Cyprus, and especially the Apliki mine. The study provides further evidence which supports the validity of the conventional approach to the use of lead isotope analysis for provenancing metals; this evidence is antithetical to recent suggestions of a model for the production of copper oxhide ingots which involved widespread mixing of copper from a number of ore sources throughout the Mediterranean.     

The Source Provenance of Bronze Age and Roman pottery from Cyprus

Archaeological interpretations of ancient economies have been strengthened by chemical analyses of ceramics, which provide the clearest evidence for economic activity, and comprise both the objects of exchange and its means. Pottery is often manufactured from local materials, but its compositional diversity typically prevents significant patterns of resource utilization from being identified. Centrally located and positioned on traditional shipping routes, Cyprus maintained ties with and supplied a variety of distinctive ceramic products to the major commercial centres in the eastern Mediterranean throughout Antiquity. We analysed two Cypriot .ne wares and a variety of utilitarian pottery, as well as samples of extant Cypriot clays to determine source provenance. These chemical analyses provide an objective indication of the origins of ancient (Bronze Age and Roman) ceramics manufactured on Cyprus. The distribution of the probable clay sources and the links between pottery style and the material environment also afford a perspective on the spatial organization of large‐scale pottery production on the island. Compositional analysis provides the means to assemble geographies of pottery production and to unravel the interregional system of exchange that operated in Antiquity, but the ability to accomplish these tasks is predicated on systematic analyses of ceramic products and raw materials that are found far beyond the bounds of individual archaeological sites.     

The potential of stable Cu isotopes for the identification of Bronze Age ore mineral sources from Cyprus and Faynan: results from Uluburun and Khirbat Hamra Ifdan

Copper isotope ratios differ between hypogene sulfidic, supergene sulfidic and oxidized ore sources. Traditional lead isotope signatures of ancient metals are specific to deposits, while Cu isotope signatures are specific to the types of ore minerals used for metal production in ancient times. Two methodological case studies are presented: First, the mining district of Faynan (Jordan) was investigated. Here, mainly oxidized copper ores occur in the deposits. The production of copper from Fayan’s ore sources is confirmed by the measurement of the Cu isotope signature of ingots from the Early Bronze Age metal workshop from Khirbat Hamra Ifdan. Based on our results illustrating differences in the Cu isotope composition between the ore mineralizations from Timna (Israel) and Faynan, it is now possible to determine these prehistoric mining districts from which copper artifacts originated by combining trace elements and Pb isotopes with Cu isotopes. The second case study presents data on Late Bronze Age copper production in Cyprus. Oxhide ingots from the shipwreck of Uluburun (Turkey) were tested for their lead isotope signatures and assigned to Cypriot deposits in the recent decades. The oxhide ingots from Uluburun show a Cu isotope signature which we also found for oxidized copper ores from Cyprus, while younger oxhide ingots as well as metallurgical slag from the Cypriot settlements Kition and Enkomi show a different signature which might be due to the use of sulfidic ore sources from a greater depth of deposits. We assert that there could be a chronological shift from oxidized to sulfidic ore sources for the copper production in Cyprus, requiring different technologies. Therefore, Cu isotopes can be used as a proxy to reconstruct mining and induced smelting activities in ancient times.     

Archaeological geophysical survey of a Prehistoric Bronze Age site in Cyprus (Alambra <Emphasis Type="Italic">Mouttes</Emphasis>)—applications and limitations

The University of Queensland Alambra Archaeological Mission (UQAAM) conducted a program of geophysical survey and archaeological excavation over four seasons from 2012 to 2016. This program has allowed this study to compile a large array of geophysical data, which has been tested against actual excavation results. By integrating the two forms of archaeological investigation, the UQAAM has been able to identify geophysical ‘signatures’ diagnostic and indicative of internal architectural features relating to the Cypriot Prehistoric Bronze Age (c2400–1750BC). This is the first time internal features have been identified using these techniques on a Middle Bronze Age site in Cyprus. The program has also identified two, and possibly four, areas of domestic settlement. This has yielded results that are of considerable value to cultural heritage managers of the site, which is experiencing development pressures. While identifying several constraints with the geophysical survey for the Prehistoric Bronze Age in Cyprus, the program has demonstrated the efficacy of a combined geophysical survey and excavation approach to sites of the Early-Middle Bronze Age period.     

BEYOND COPPER: COMMODITIES AND VALUES IN MIDDLE BRONZE CYPRO‐LEVANTINE EXCHANGES

During the transition from the Middle to Late Bronze Age, Cyprus became a full participant in the Levantine maritime interaction sphere. This is reflected in the archaeological record by a dramatic increase in the Cypriot pottery found in the surrounding region, widely assumed to be the by‐product of an (archaeologically invisible) external demand for Cypriot copper. On the receiving end of this relationship, small numbers of imported ‘luxury’ goods appear on Cyprus. This paper discusses one aspect of exchange that has received little attention in the literature, the presence and significance of quantities of imported transport amphorae (Canaanite jars). These vessels have only rarely been recognized from excavations on Cyprus but recent examination of material from several sites reveals that they are more common than previously assumed. The Canaanite jar evidence may go some way towards redressing the apparent imbalance in goods exchanged and also to illuminate the processes through which Cypriot populations first engaged with the materiality of urban ways of ordering the world.     

Specialization and social inequality in Bronze Age SE Arabia: analyzing the development of production strategies and economic networks using agent-based modeling

This paper investigates the role of specialized production strategies in the development of socio-economic inequalities in Bronze Age south-eastern (SE) Arabia, and particularly, the ways in which a localized, internal exchange economy may have produced stress and instability in the SE Arabian socio-economic system. While archaeological research has established that the communities of SE Arabia participated in a widespread Bronze Age exchange system that included areas of the ancient Near East, South Asia, and Central Asia, it is unclear to what degree this interaction fostered the broad-scale socio-economic changes seen in the Early Bronze Age of SE Arabia. Here we present the results of an agent-based model that suggest the nature of the internal exchange economy in SE Arabia itself may have precipitated the social conditions necessary for change by allowing individuals to profit disproportionately. We thus emphasize the importance of local production strategies in generating socio-economic change, in addition to the well-established economic and cultural contacts with the wider Bronze Age world.     

The prehistory of Cyprus: Problems and prospects

The archaeological record of prehistoric Cyprus is rich, diverse, well-published, and frequently enigmatic. Regarded by many as a bridge between western Asia and the Aegean, Cyprus and its past are frequently seen from scholarly perspectives prevalent in one of those two cultural areas. Its material culture, however, differs radically from that of either area. Apart from the early colonization episodes on the island (perhaps three during the pre-Neolithic and Neolithic), evidence of foreign contact remains limited until the Bronze Age (post-2500 B. C.). This study seeks to present the prehistory of Cyprus from an indigenous perspective, and to examine a series of archaeological problems that foreground Cyprus within its eastern Mediterranean context. The study begins with an overview of time, place, and the nature of fieldwork on the island, continues with a presentation and discussion of several significant issues in Cypriot prehistory (e.g., insularity, colonization, subsistence, regionalism, interaction, social complexity, economic diversity), and concludes with a brief discussion of prospects for the archaeology of Cyprus up to and beyond 2000.     

EARLY BRONZE AGE METAL TRADE IN THE EASTERN MEDITERRANEAN. NEW COMPOSITIONAL AND LEAD ISOTOPE EVIDENCE FROM CYPRUS

Summary.   This paper presents the results of chemical and lead isotope analyses of 17 Early and Middle Bronze Age artefacts from Cyprus. These suggest that a number of objects are of non-Cypriot copper and lead to the identification of several as imports, a new explanation for some artefact types as ingots and a discussion of the nature of deposits at the key Cypriot site of Vasilia. This in turn allows a reconsideration of the role of Cyprus in an Aegean/eastern Mediterranean metals trade in the early years of the second half of the third millennium BC and of the development of metalworking on the island.     

Archaeometric Clearinghouse XX

Abstract

This article is a review of three recent monographs concerned with the later Middle Cypriote and Late Cypriote periods on Cyprus (ca. 1700–1200 B.C.). Each study focuses narrowly on archaeological, philological, or historical problems associated specifically with Cyprus or more generally with interrelations among Aegean, Cypriote, and eastern Mediterranean cultures. Oblivious to common interests, the authors reflect their own particularistic concerns: philology, toponymy, stone anchors. The three publications reviewed serve both as a framework and as a vehicle for presentation of a balanced discussion of archaeological, historical, and theoretical problems associated with Middle/Late Bronze Age Cyprus and its role in eastern Mediterranean maritime trade. In conclusion, and as an alternative, a concise synthesis of cultural and socio-historical patterns on Cyprus ca. 1700–1200 B.C. is presented.

The three volumes under review are: L. Hellbing, Alasia Problems. StudMedArch 57 (P. Åström's Förlag: Göteborg 1979); D. E. McCaslin, Stone Anchors in Antiquity: Coastal Settlements and Maritime Trade Routes in the Eastern Mediterranean. StudMedArch 61 (P. Åström's Förlag: Göteborg 1980); J. Strange, Caphtor/Keftiu, A New Investigation. Acta Theologica Danica 14 (E. J. Brill: Leiden 1980).     

Identifying stone tools used in mining,smelting, and casting in Middle Bronze Age Cyprus

Abstract

Metallurgical production sites are often difficult to identify in the archaeological record because ore beneficiation and slag processing in the past involved the use of ground stone tools that were similar to those used in other contexts to prepare cereals and foods. Analysis of the ground stone assemblage from a Middle Bronze Age copper mining and production site at Ambelikou Aletri in Cyprus provided an opportunity to distinguish industrial and domestic ground stone tools and to identify the types of tools used in different stages of metal production. A comparison of tool morphologies, raw materials, and wear and breakage patterns from Ambelikou Aletri with those from contemporary domestic contexts, suggests that distinctions in the nature and structure of industrial and domestic tool kits do exist and those distinctions have an important role to play in identifying mining, smelting, and casting sites in the future.     

Late Bronze Age Copper Smelting Slags from Luserna (Trentino,Italy): Interpretation of the Metallurgical Process

In the Late Bronze Age, the extractive metallurgy of copper in north‐eastern Italy achieved a peak of technological efficiency and mass production, as evidenced by the substantial number of metallurgical sites and the large volume of slags resulting from smelting activities. In order to define the technological features of the Late Bronze Age metallurgical process, more than 20 slags from the smelting site of Luserna (Trentino, Italy) were fully analysed by means of optical microscopy, X‐ray powder diffraction, X‐ray fluorescence spectrometry and scanning electron microscopy. Three different slag types were identified based on mineralogical and chemico‐physical parameters, each being interpreted as the product of distinct metallurgical steps. A Cu‐smelting model is proposed accordingly.     

The Cape Gelidonya Shipwreck and the Bronze Age Metals Trade in the Eastern Mediterranean

Abstract

Controversy has surrounded the identification of the home port of the ship wrecked off Cape Gelidonya, Turkey. In an attempt to contribute further information pertinent to the solution of this problem, samples for metallurgical study were taken from eight of the copper ingots that were carried on the ship: four oxhide-shaped, two plano-convex, and two slab-shaped. Analysis of these samples shows that, with a single exception, the structure and composition of the ingots are little different from ingots found in Cyprus, Crete, Greece, and Sardinia. The inferences to be drawn from the metallurgical research are 1) that the ingots represented typical items of international trade and 2) that the home port of the ship and lading port of the ingots cannot be determined since the ship and crew were operating in the international sphere. It may also be surmised that at least a part of the Bronze Age trade was in the hands of private entrepreneurs.     

Using neutron activation analysis to identify scales of interaction at Kinet Höyük,Turkey

We use NAA to characterize a relatively large archaeological ceramic sample from the Late Bronze Age to Hellenistic phases of Kinet Höyük, a coastal Turkish site in the Gulf of Iskenderun at the northeast corner of the Mediterranean Sea. The geographic extent of local Kinet wares (how local is local?) is established through comparison with sediment samples across the Kinet hinterland. Four major compositional groups are identified: local and locally imported wares, imports from Cypriot, and presumed Western Anatolian and Aegean centers, and imports that appear relatively homogenous elementally but comprise typologically diverse ceramics with attributions that range from Cyprus to the coastal mainland. Comparison with other published NAA studies for this site reinforces the elemental evidence for local production, and underlines the need for caution when assuming local production always equates with local clays particularly for coastal sites. We propose that the chronological distribution of the local and non-local groups provides a useful political economic proxy. The study indicates systemic and widespread political disruption and marginalization at the transition to the Late Iron Age in this region.     

Long-term agrarian landscapes in the Troodos foothills,Cyprus

We investigate the temporal and environmental relationships between the terraced hill slopes of Politiko-Koloiokremmos and the adjacent Bronze Age settlement of Politiko-Troullia in foothills of the Troodos Mountains, central Cyprus. Mapping of 102 stone walls on Koloiokremmos is compared with 66 walls farther afield on Cyprus to create a six-part terrace typology. Sherd counts from 174 2-m radius collection circles over approximately 20 ha on Troullia and Koloiokremmos were used to create interpolated sherd density surfaces revealing distinctly different patterns of land use for four major archaeological eras between the Cypriot Bronze Age and Medieval Period. We compared sherd density patterns according to terrace types, length, slope and vegetation cover determined by SAVI (Soil-Adjusted Vegetation Index) from Ikonos and Quickbird satellite imagery.The most robust sherd patterning indicates Prehistoric Bronze Age settlement at Troullia, as confirmed by soil resistivity and excavation, and multi-period land use on Koloiokremmos immediately upslope of the village that may be associated with agricultural terracing. Scattered sherd concentrations indicate later use of this landscape as an agricultural hinterland for the Iron Age city of Tamassos. Sherds and a down slope spread of roof tiles from the Roman through Medieval periods suggest an isolated structure near the crest of Koloiokremmos. Longer terraces correlate with greater vegetation cover and are interpreted as agricultural, while shorter terraces, apparently for erosion control and arboriculture, are significantly related to Prehistoric Bronze Age sherd patterns. Our results suggest that coordinated analysis of archaeological, geographical and remotely sensed environmental data associated with terraced landscapes can be used to infer long-term patterns of agricultural land use.     

Lead isotopic analyses of copper ores in the Early Bronze Age central Hexi Corridor,north-west China

This paper explores the possible provenance of ores employed for metallurgical production during the Early Bronze Age in the central Hexi Corridor of north-west China. In total, 78 pieces of copper (Cu) ore samples were collected from five Early Bronze Age sites and one Cu deposit site (the Beishantang Cu deposit) in the Heihe River region of the central corridor. These sites were dated to the late Machang (4100–4000 bp ), Xichengyi (4000–3700 bp ), Qijia (4000–3600 bp ) and Siba (3700–3400 bp ) cultures. After comparing with published lead (Pb) isotopic data from other possible Cu deposits in north-west China, the results show that the Cu ores collected from the Early Bronze Age sites were most likely derived from the adjacent Beishan Cu deposit. More intriguingly, for the first time in Hexi Corridor, a dozen Cu ores were discovered containing highly radiogenic Pb. Though fundamentally different from those in the Central Plains, they illustrate a possible new type of Cu used in Bronze Age western China, and the first-hand materials are significant for further understanding the provenance of raw metals for metallurgical production in the prehistoric Hexi Corridor.
