Introduction

During the Late Bronze Age (LBA; c. 1500-1200 BC) the eastern Mediterranean underwent large scale economic and political changes (Sherratt 1998; Oren 2000). These transformations involved the elaboration of a metals-based economy supporting a dense and complex network that linked Europe, Africa and Asia for the first time (Edens 1992). In an environment where the palatial societies of the Hittites, Mycenaeans and Egyptians were major beneficiaries of this early maritime 'World System', Cyprus stands out as a key supplier (Knapp 2013). The distribution of Cypriot oxhide' copper ingots (both as artefacts and in representations) highlights the island's importance in the operation of the wider metals-based exchange system (Gale 1991; Budd 1995). In addition to the exploitation of raw materials (i.e. precious minerals, ivory, wood), many other novel manufactured goods also circulated in the LBA economy (Keswani 1993, 1997).

Evaluating the social and political dynamics associated with ancient economies is one of the most challenging issues in archaeology. Analytically, a fundamental challenge is identifying the origin of the goods exchanged. In this paper we use a case study from the eastern Mediterranean to illustrate a robust and systematic approach to establishing provenance for trade ceramics and understanding the scope of geospatial uncertainty. Three features make Late Bronze Age (LBA) Cyprus a useful case study: first, it was a major producer of a wide range of ceramics that were prominent in eastern Mediterranean trade at this time (Barlow et al. 1991; Karageorghis 2001; Astrom 2008), and Cypriot polities played a key role in defining the economic dynamics of the LBA eastern Mediterranean. Second, legacy Neutron Activation Analysis (NAA) datasets exist for a relatively large and diverse sample of Cypriot ceramics. And lastly, Cyprus has a highly complex but well defined geology with excellent potential for direct geochemical linkage with this ceramic corpus.

Cyprus has a dense archaeological record with a long history of excavations (Astrom 1994; Knapp 2013), and hence provides an exceptional record of the regional distribution of ceramics. In part due to this record, Cyprus is also one of the first areas where archaeologists collaboratively pursued larger analytical studies to understand regional trade and exchange (Knapp & Cherry 1994). Considerable progress has been made characterising Cypriot archaeological ceramics using elemental and mineralogical analytical techniques, which in some cases have linked types to specific locales (Vaughan 1987, 1991; Rautman et al. 1999; Gomez et al. 2002; Coren et al. 2003; Rautman & Neff 2006; Tschegg et al. 2009). A number of synthetic studies have produced relatively fine-grained geopolitical interpretations of LBA dynamics within Cyprus (e.g. Keswani 1993, 1997; Knapp 2013). However, a general shortcoming of this work is that few connections have been made between the geopolitical interpretations and the potential geospatial range and diversity of Cypriot LBA ceramic production.

The goal of this study is to identify the geochemical provenience of well-known and widely traded Cypriot ceramic types (e.g. White Slipped, Base Ring, Bichrome Wheelmade) to explicate further the patterns of exchange for elite goods in the LBA eastern Mediterranean. A more specific focus is to identify the geographic origin of a class of LBA ritual ceramic (Red Lustrous Wheelmade Ware (RLW); Eriksson 1991). RLW was one of the most widely traded ceramic types of the LBA and has variously been argued to have been produced in an as-yet unidentified location within Cyprus, as well as in other locations around the eastern Mediterranean (Eriksson 1993).

Methodologically, this study underlines how defining ceramic provenience in terms of geological precincts enables a more robust and systematic evaluation of the relationship between geographical scale and ceramic type diversity. The combined datasets that have been used (new Neutron Activation Analyses of both sediments and ceramics and a large legacy NAA dataset of Cypriot ceramics from the Lawrence Berkeley National Laboratory) are available for download through Open Context.

Problems of provenience

Cypriot ceramics have long been the focus of archaeometric research (e.g. Millett & Catling 1966; King et al. 1986; Vaughan 1987; Rautman & Neff 2006; Rautman et al. 1999). Lawrence Berkeley National Laboratory (LBNL) conducted the largest single analytical programme for ceramics from Cyprus over the course of three decades. Using NAA to characterise over 1500 Cypriot ceramic samples, the LBNL group demonstrated that the wide range of Cypriot ceramic types could be tied to a more limited set of compositional profiles (Knapp & Cherry 1994; Boulanger 2011). While the size of this NAA programme for Cypriot ceramics is unparalleled, these data have remained disconnected from the island's geochemistry.

A variety of archaeometric studies have suggested specific 'point-source' proveniences for Base Ring Ware (e.g. Vaughan 1987; Gomez et al. 2002), one of Cyprus' widely traded LBA ceramic types. The provenience of Red Lustrous Wheelmade Ware, on the other hand, has remained contentious despite several recent analytical studies. With an archaeological distribution extending from Anatolia to Egypt, RLW is one of the few LBA trade items that closely follows the geopolitics described in the Amarna Letters, a unique archive of correspondence between contemporary LBA rulers of this region (Moran 1992) (Figure 1). Excavations at Hittite centres in central Anatolia have revealed both the most abundant and the oldest RLW (Mielke 2007; Schoop 2009).

RLW had a 300-year production history, occurring archaeologically as an important elite or ceremonial ware in the major Anatolian LBA centres. It first appeared during the last decades of the sixteenth century BC, but remained relatively uncommon until the late fifteenth century BC. Around 1400 BC a large quantity of RLW was dumped into an abandoned water reservoir at the inland Hittite capital of Hattusa in central Anatolia (Figure 1). This dump constitutes the largest recovered assemblage of RLW from one site (Seeher 2001, 2002). Over the following 200 years, RLW became a regular component of Hittite temple assemblages. Elsewhere in the Eastern Mediterranean, including Cyprus, Egypt and the Levant, RLW is more commonly associated with mortuary assemblages in tombs (Eriksson 1993; Kozal 2003; Knappett et al. 2005; Hein 2007). RLW finally disappears from the archaeological record around 1200 BC, coinciding with the systemic collapse of LBA palace economies across the region.

Typologically, RLW comes in a variety of shapes including bowls, craters and jugs (Figure 2). The most common forms include tall, slender, one-handled jugs ('spindle bottles'); flasks with a broad body ('lentoid flasks'); and enigmatic anthropomorphic vessels ('libation arms'), each with a long, tubular 'arm' terminating in an opening in the form of a human hand holding a cup (Figure 2a). Physically, RLW has a visually highly distinctive ceramic fabric that is completely oxidised, bright orange, very fine-grained and homogenous, with a red burnished surface. Throwing marks on the inside of many RLW spindle bottles and libation arms (i.e. created before firing) highlight the mechanical properties of the clay used for RLW, which combined a high degree of plasticity with tensile strength (Figure 2b). Analytically, RLW vessels are mineralogically and geochemically homogenous and distinctive. Together, the typological and material characteristics of RLW are consistent with specialised production focused on an unusual and high-quality clay source (Knappett et al. 2005).

For ceramicists, as for biologists, both abundance and diversity are commonly used to define the location of origin of specific types. Early conjectures located RLW production in Syria because of its relative abundance at coastal LBA entrepots such as Ras Shamra (Ugarit) (Eriksson 1991). From its ubiquity, central Turkey might also be proposed as a possible production centre for the ware, as the Hittite capital Hattusa provided the largest single concentration of excavated RLW. However, both the Syrian and Hittite contexts for RLW have only yielded a subset of the known forms. The island of Cyprus, on the other hand, while second to Bogazkoy in terms of abundance of RLW, has preserved the full typological range of RLW. For Eriksson (1991, 1993), this flagged Cyprus as the likely source of RLW. Within the island, the quantity and diversity of RLW types recovered from tomb contexts on the northern coast have been further used to suggest this region as a probable centre of production (Eriksson 1993, 2007).

Previous work: geology and ceramics

The compositional diversity of Cypriot ceramics can largely be understood in terms of the complex geology of Cyprus (a series of diverse and spatially discrete ophiolites, limestones and volcanic intrusions). The evidence of the formation of the Tethys and Mediterranean Seas that it preserves has made Cyprus a major focus of litho-stratigraphic and plate tectonic research (e.g. Swarbrick & Robertson 1980). Additionally, its ongoing importance as a major source of copper ore has also attracted the interest of economic geologists. As a result, Cyprus is one of the more comprehensively researched geological precincts of the eastern Mediterranean (e.g. Northmore et al. 1986; Lapierre et al. 2007) (Figure 3).

Cyprus is composed of four major geological provinces. From north to south these are the Kyrenia Terrane, the Circum-Troodos sedimentary succession, the Troodos Ophiolite complex, and the Mamonia Complex in the south-west (Geological Survey Department 1993). The Kyrenia Terrane is a complex of sedimentary (limestone) deposits with limited igneous and metamorphic rocks. The southern side of the Pentadaktylos range, within the Kyrenia Terrane, includes a set of interbedded chalks and marls. The Circum-Troodos sedimentary succession consists of a range of marine deposits overlain by clastic deposits of gravels, sands and silts. The Troodos Ophiolite complex is an uplifted piece of oceanic crust with volcanic and hydrothermal intrusions. Copper, exploited since the Bronze Age, is associated with the massive sulphide mineral deposits in this complex. The Mamonia Complex comprises two general geological units, a lower Jurassic/Triassic unit of mainly extrusive alkaline igneous rocks, reef limestones and hemi-pelagic sediments, and an upper group (extending into the Miocene) of thin-bedded cherts, siltstones, limestones and quartz sandstones (Swarbrick & Robertson 1980; Lapierre et al. 2007). This Complex forms an arc-shaped region in south-western Cyprus. Within the upper unit are the greenish bentonitic clays of the Kannaviou complex, patchily distributed around the Mamonia arc, which are crucial to this study. This geospatial complexity is key to identifying likely ceramic production areas across the island.

Methodology

Geochemical profiling has proven a highly effective tool for the archaeological reconstruction of patterns of trade and exchange through linking unique elemental signatures with spatially constrained geological sources (Glascock & Neff 2003). Geochemical studies of archaeological obsidian provide one of the best exemplars for this type of proveniencing: the highly localised character of volcanic glass deposits coupled with distinctive volcano (or even flow-) specific geochemical signatures typically enables very precise predictions of the geological origin of an obsidian artefact (Reepmeyer et al. 2011). Archaeological ceramics have also been the subject of extensive geochemical proveniencing studies, but the interpretation of results faces greater challenges, particularly in controlling for the spatial variability of the parent material and the effects of clay processing (Neff et al. 2006).

There are two general approaches to ceramic elemental analysis: in one, production centres are inferred from the elemental composition of well-known ceramic types whose location is otherwise constrained; in the other, the identification of local production is attempted through matching the geochemistry of discrete clay beds ('point-sourcing') with elemental profiles of archaeological ceramics. While clay beds exploited in antiquity for ceramic production could be presumed to have been spatially restricted (Whitbread 2003), they were also typically derived from geological formations that may have extended over a far wider area (e.g. benthic limestones). Rarely is the spatial range of geologically defined source areas for ceramics adequately quantified or characterised (Price & Burton 2011). As a consequence of these substantial uncertainties, ceramic provenience arguments often remain inconclusive.

We suggest that a geochemical match between a clay bed and local ceramics cannot be taken as an adequate or sufficient demonstration of provenience. Instead, we argue that a more robust alternative is to focus on the geochemical precincts of regional parent geologies. This enables us to gain a better understanding of the potential scale of ceramic production regions. We address the issue of scalar variability in geological source material through an extensive sediment sampling regime across the four geological precincts of Cyprus (Figure 3). Some locations, with multiple geological units, required several samples; conversely, larger geological units were sampled over multiple locations.

This study makes use of NAA to characterise sediments and ceramics. We compare NAA results for a sample population of RLW from Bogazkoy, the LBNL Cypriot ceramic NAA dataset (including RLW), and our Cypriot sediment sample. The aim of this comparison is to evaluate the geochemical relationship between different ceramic compositions and geographic locales around the island, to relate geological deposit size with ceramic diversity, and specifically to identify the most likely production region(s) of RLW within Cyprus.

Previous studies have suggested that in some cases there are systematic offsets in NAA data from different facilities that require correction (Hein et al. 2002). In this case we lacked standards that had been used by the LBNL facility which would have made it possible to identify the presence of an analytic offset. In the absence of common standards, we therefore relied on the presence of RLW results in the LBNL dataset and the demonstrated compositional homogeneity of this fabric. To establish that we could effectively combine the NAA results from the LBNL dataset and the present study in a single analysis, we analysed the two datasets together. Comparability was empirically established through Principal Components Analysis of the combined RLW results (reduced to common elements), where RLW from both datasets fell in close and overlapping proximity in multivariate space, demonstrating the absence of any significant offset. Based on this close similarity, we determined that the two larger datasets could be reliably combined. This correspondence between different NAA facilities is consistent with our previous work combining legacy datasets (e.g. Grave et al. 2013).

Direct comparison of NAA results for sediments and ceramics is more problematic, however, owing to gross differences in elemental concentrations largely related to differences in mineral content (primarily quartz). Ceramic fabrics generally reflect homogenising processes that include the removal of organics and the alteration of mineral concentrations. To minimise potential compositional differences between processed ceramic and potential source sediments, the original quantitative results are transformed into dimensionless quotients using a scandium (Sc) ratio procedure (Dias & Prudencio 2008). This method enables direct comparison with the Cypriot sediment dataset and the identification of relationships between sediments, the RLW samples and the suite of LBNL ceramics (Table 1). The data are evaluated and compared using unsupervised and supervised multivariate methods.

Results

Principal Components Analysis (PCA) of the combined RLW, sediment and LBNL NAA datasets (Tables 1-3) shows a highly structured assemblage with four major geochemical groups and a number of subsets (Figure 4a). Around 80 per cent of the NAA results for the sediment samples approximated ceramic compositional groups. The correlations between the ceramic and sediment NAA results allow us to establish connections between geochemical groups representing geologically distinct regions of the island, and different classes of ceramic. Our four compositional groups mirror the four main geological provinces in Cyprus (Figure 4c). Group 1 is from the Circum-Troodos sedimentary succession, Group 2 is from the Kyrenia Terrane, Group 3 from the Troodos Ophiolite complex, and Group 4 from the Mamonia Complex. These findings support previous work on Cypriot geochemistry that demonstrated a close correlation between sediments and underlying geology (Cohen et al. 2012). The correlations between ceramic and sediment geochemistry also highlight the differences in size between geochemical and ceramic source areas across the island (Figure 4b).

Group 1 is the largest ceramic group of our study, with the greatest typological diversity and the widest chronological range. It also includes sediments that are the most broadly distributed, spread across the alluvial plains and coastline of central and southern Cyprus. The diversity of ceramic types associated with Group 1 could potentially be provenienced from anywhere Group 1 sediments occur (see Technical Note for Group 1 ceramic types).

A number of the more spatially confined groups include a smaller range of ceramic types (for example, Group 2 is predominantly Red Polished Ware from Lapithos; Group 4 is dominated by subsets that contain single ceramic types such as Base Ring Ware (BRW)).

Conversely, Group 3 is unusual in the context of the otherwise predictable sample-size relationship between spatial scale and ceramic type diversity, where we expect larger regions to produce more ceramic types. On one hand, Group 3 represents the Troodos ophiolite covering an area almost as extensive as the Group 1 source region, while on the other it contains an anomalously small range of wares (White Slipped and variants). This suggests unusually specialised production and/or relatively few production sites within a mountainous region that remains sparsely inhabited today.

[FIGURE 4 OMITTED]

For each group, there is a clear chronological sequence in the stylistic types, indicating that while the range of types can be large, a much more limited number were produced in any given period. For example, the Group 2/North Coast Lapithos samples are predominantly Neolithic; Group 3/Troodos types were produced only in the Bronze Age; while production of Group 3.1/western Mesaoria Plain types only commenced in the Middle Iron Age.

The provenience of Red Lustrous Wheelmade Ware

RLW and geochemically associated wares (e.g. BRW) are members of Group 4, a group that separates into four distinct, but compositionally closely related, subsets: 4.4 consists exclusively of the RLW samples (from both the LBNL and Bogazkoy datasets); 4.1 and 4.2 account for the majority of BRW samples (LBNL), and 4.3 includes a range of Cypriot Black Slip and Mycenaean-style wares (LBNL) (Figure 4d).

Group 4 also includes matches with several sediment samples restricted to two locations in western Cyprus. One sediment pair was collected near the modern village of Mamonia (AIA7214, 7216); the second pair from Kritou Tera (AIA7179, 7181), a locale 28km to the north of Mamonia towards the Akamas peninsula (Figure 4e). While apparently disparate, the locations of these sediment matches both lie in the Mamonia Complex, a highly distinctive, narrow U-shaped formation of greenish bentonitic clays unique to western Cyprus. The sediment matches point to an origin for Group 4 ceramics in that Complex. The small compositional offsets between the Group 4 subsets probably reflect exploitation of slightly different beds within this formation (Northmore et al. 1986), compounded by differences in technological treatments between ceramic classes (e.g. handmade BRW versus wheelmade RLW).

Group 4 subsets are largely Bronze Age in date, suggesting that the LBA was a period of intensive elaboration of ceramics in western Cyprus, consistent with the documented expansion of economic networks across the larger region (Sherratt 1993; Keswani 2005). Group 4.1 occurs in the MBA to LBA. Group 4.3 includes ceramic types that chronologically begin in the LBA and continue into the LIA. Groups 4.2 and 4.4 occur only in the LBA. See Technical Note for Group 4 ceramic types.

Discussion

Through the combined analysis of new and legacy NAA for both ceramics and sediments, we have been able to map the provenience of the main LBA (and other) ceramics across the four geological precincts of Cyprus. In the case of RLW, the bentonitic clays within the Mamonia Complex of western Cyprus are the source for this Late Bronze Age ware. The implication is that RLW and related wares, rather than being a trade good produced in Anatolia or Syria as part of the 'balance of trade' in the LBA metals economy, are significant high-value elements of the LBA western Cypriot economy.

The transport of RLW from south-western Cyprus to the inland Hittite capital of Hattusa, however, is a unique phenomenon. Not only does it represent overland transport of a large number of very fragile vessels, but it is the only eastern Mediterranean pottery import that is found at Hattusa in any quantity. This suggests that the role of RLW in Hittite society was not only tied to local ritual but was critically intermeshed with LBA elite ideology and power in the eastern Mediterranean.

Our results also demonstrate a predictable relationship between size of geochemical source region and range of ceramic types. Deviations from this pattern, as with Group 3, flag an unusual production environment requiring further evaluation. In the case of Group 4, the small number of types, including RLW, not only fits with the relatively constricted range of the potential source area but also with predominantly single-period (LBA) exploitation. We suggest that these results require a more spatially nuanced assessment of the importance of different production regions over time.

This study highlights the importance of large scale geochemical mapping of the landscape for ceramic provenience studies targeting large-scale exchange networks. Economic and political dynamics can play out over extensive regions, particularly in areas reliant on maritime connections, as in the eastern Mediterranean (Pulak 1998; Sherratt 2000). By matching ceramic elemental data with geological precincts, we have been able to establish the degree of spatial resolution possible for different geochemical groups. The approach taken here enables identification of highly specific geological source regions for even widely distributed ceramics, as well as allowing a better understanding of redundant geochemical groups that can either be geographically very extensive or recur across the region, like Group 1. New techniques may improve analytical resolution of provenience studies but defining the areal differences between geological sources will continue to be a central challenge.

While this study demonstrates that the re-use of legacy NAA datasets can be very productive for contextualising new research, we have focused only on the largest and currently most readily accessible datasets. The inclusion of other NAA studies for Cyprus, such as those undertaken by the Brookhaven National Laboratory in the 1970s, are beyond the scope of the present work. However, these datasets, while unlikely to alter our basic understanding of the relationship between geological precincts and ceramic compositional profiles established here, should enable further refinements as more comprehensive studies are undertaken in the future.

Conclusions

Identifying the production area of RLW allows us to re-evaluate local responses to the new opportunities offered by the LBA economy on the island of Cyprus. On one hand, Cypriot copper--almost entirely obtained from ore bodies in central Cyprus, on the northern flanks of the Troodos Range, during the LBA--became central to the production and distribution of bronze throughout the Mediterranean. Keswani (2005), for example, suggests that competitive elite public mortuary displays, including copper items, were critical for driving the development of Late Cypriot complexity. On the other hand, we see that groups occupying the far western parts of the island that were not exploited for copper at this time and had been generally assumed to be largely agrarian, actively invented new 'value-added' goods that also became an important part of the LBA Cypriot economy. It is possible that in this new economy 'value-adding' was an effective strategy within Cyprus, to compensate for a metal-poor location away from the major copper-bearing zone of the northern flanks of the Troodos. While BRW fits a value-adding model (Sherratt 1993), the distribution of RLW suggests a more complex set of processes. Groups in western Cyprus, therefore, engaged in a range of strategies, targeting not only domestic but also regional ritual consumption, expanding their status and power across the larger region.

From the limited presence of RLW in the known archaeological sites on the southern coast of western Cyprus, we suggest that the Chrysochou River catchment, draining northward into the Chrysochou Bay, was a more likely production region than the eastern portion of the Mamonia Complex. The fragmentation of production regions across Cyprus supports Keswani's (1993, 1997) argument for a complex multi-polity Cyprus during the LBA. Keswani suggests that there were strong politico-economic links between coastal sites, inland cult sites and mining sites for the production of copper. A similar control network may have operated in the Chrysochou River basin for the production of RLW. More recently, others have argued for a single state or polity unifying the island of Cyprus, based on textual data (Alasiya') (Peltenburg 2012; Knapp 2013), although the archaeological evidence remains equivocal.

These findings highlight the need for a reassessment of the archaeological evidence for LBA ceramic production in Cyprus. Until recently, archaeologists have tended to focus on the major urban centres and palatial economies, with an emphasis on patterns of exchange and consumption. However, beyond Cyprus' role as a copper producer, we can now say that western Cyprus, in particular, was a major producer of multiple classes of LBA ceramics, such as RLW, that became important elements in defining status and power across the broader region, from Egypt to inland Anatolia. In spite of the current paucity of RLW finds, a centre in western Cyprus must have played a pivotal, and currently underestimated, role not only in the production and exchange of high-value ceramics but also in the development of the multi-faceted LBA Mediterranean 'World System'.
