The Asiatic marbles of the Hadrian's Villa at Tivoli

Multi-method provenance studies, including petrographic, isotopic, electron paramagnetic resonance and trace chemical analyses, have been carried out on 20 white, 9 black and 1 red artifacts purposely selected to investigate the use and distribution of sculptural marbles at the Hadrian's Villa. A large fraction of the marbles tested (21 samples, 70%) are shown to be from Asia Minor, mostly originating from the recently discovered site of Göktepe near Aphrodisias (15 or 71%). All the 9 black samples investigated and 6 out of 11 white Asiatic marbles are from Göktepe, the remaining being Docimium marble from Iscehisar (4 samples) and Aphrodisias marble from the city quarries (1 sample). The single red sculpture tested proved to be Carian red marble from the Iasos quarries, whereas non-Asiatic marbles include 3 Carrara and 6 Pentelicon samples. The selection of marbles tested is preliminary and incomplete, but, despite this, the results are noteworthy, especially since the marble of other sculptures from the Villa has already been identified as Göktepe. Together with other published results, the marble distribution at the Hadrian's Villa seems to suggest that the use of sculptural marbles in the Roman world underwent considerable changes around the turn of the 1st and the 2nd century AD. The evidence supporting this hypothesis is briefly summarized in the conclusions.     

Archaeological carved slabs of the Langobard art in churches of Peligna Valley and Spoleto (Italy): provenance of the stones

In this study we investigate the provenance of the limestone and marble used to made carved slabs today placed in three churches located in Raiano and Vittorito (Peligna Valley, Abruzzo, Italy) and in Spoleto (Umbria, Italy). The slabs, representative examples of the Langobard art (Middle Ages), are dated approximately from 8th to 9th centuries A.D. and have the same pattern in terms of decoration, suggesting a progressive expansion of Langobards in central and southern Italy, after the foundation of the Pavia Kingdom.     

Site formation processes in caves: The Holocene sediments of the Haua Fteah,Cyrenaica, Libya

Caves have yielded some of the most globally important archaeological sequences, but often their interpretation has suffered from assumptions about cave sedimentary processes. Caves contain distinctive sedimentary environments: this has major implications for the understanding of contained archaeological materials. This paper describes and analyses the Holocene sediments in the Haua Fteah, a sequence regarded as essentially continuous by the original excavator. 50 years after it was first excavated, the Haua's Epipalaeolithic to post-Classical chronological range and rich finds make it still the key Holocene archaeological site in North Africa. The reassessment shows, however, that the sequence is strongly discontinuous and this has major implications for the reinterpretation of the site, as the highly-resolved archaeological record is thus likely to reflect a series of brief occupations, rather than continuous human activity. As with many caves, the sedimentary record in the Haua Fteah is an extremely sensitive indicator of environments and processes in the wider landscape. Secure understanding of sedimentary process, from analysis of the highly individual records found in caves, is essential for full understanding of their contained archaeology.     

A Multi‐Method Database of the Black and White Marbles of Göktepe (Aphrodisias), Including Isotopic,EPR, Trace and Petrographic Data

A database of the ancient marbles of Göktepe near Aphrodisias is reported, and includes 160 white, black and bichrome samples from 13 quarries and two waste deposits. The quarries are grouped into four districts. Districts 1 and 2, to the north, produced exclusively black or dark grey marbles (nero antico). Districts 3 and 4 produced white statuary marble. Nero antico and a black and white stone were also quarried in district 4, where the black marble surfaces again. The samples were characterized using petrography, isotopic analysis, EPR spectroscopy and trace analysis. The Göktepe white exhibits an unparalleled combination of fine grain, low EPR intensity and high strontium concentration that often allows easy identification. The isotopic values are less distinctive and similar to those for Carrara. In most cases, however, they are tightly grouped and also quite indicative. The black marbles exhibit a much weaker metamorphic overprint. With respect to the white marbles, they show analytical similarities but also notable differences. Therefore, establishing their provenance can be more difficult and may require the support of petrographic analysis. The results suggest that the Göktepe marbles were among the most prized and widespread statuary marbles used in Roman times, particularly from the early second century ad onwards.     

The White Marble of the Arch of Augustus (Susa,North‐Western Italy): Mineralogical and Petrographic Analysis for the Definition of its Origin

The Arch of Augustus in Susa (north‐western Italy) was built in 9–8 bc by King Cottius, to celebrate the treaty between the Romans and the Gauls. It is made of white marble, which was considered for a long time to be locally extracted, but no archaeometric studies have been performed up to now. Therefore, a multi‐analytical study based on petrographic (optical and scanning electron microscopy), electron microprobe and stable isotope analyses was carried out on the marble from the arch and from reference samples, with the aim of defining the provenance. All the data confirmed that white marble belonging to the metamorphosed carbonate cover of the Dora Maira Massif, known as Foresto marble, was used for the Susa Arch. This choice was probably made for economic reasons, but also due to the relative independence of the ruling family of the Alpes Cottiae, which was obviously interested in promoting a local marble.     

Tracing Medieval and Renaissance Alabaster Works of Art Back to Quarries: A Multi‐Isotope (Sr,S, O) Approach

Multi‐isotope fingerprinting (sulphur, oxygen and strontium isotopes) has been tested to study the provenances of medieval and Renaissance French and Swedish alabaster works of art. Isotope signatures of historical English, French and Spanish alabaster source quarries or areas are revealed to be highly specific, with a strong intra‐group homogeneity and strong inter‐group contrasts, especially for Sr and S isotopes. The chosen combination of isotope tracers is a good basis for forensic work on alabaster provenance, allowing verification of hypotheses about historical trade routes as well as identification of fakes and their origin. The applied analytical techniques of continuous flow isotope ratio mass spectrometry (CF–IRMS) and thermal ionization mass spectrometry (TIMS) only require micro‐samples in the low‐milligram range, thus minimizing the impact on the works of art.     

Variscite source and source analysis: testing assumptions at Pico Centeno (Encinasola,Spain)

The analysis of trade and their implications for understanding social interaction is a major research question of prehistoric research in Europe. Variscite is a rare mineral that offers an excellent opportunity to study trade and exchange patterns in prehistoric Europe through proveniencing of source material.     

Geochemical signatures of Roman amphorae produced in the Sado River estuary,Lusitania (Western Portugal)

Several archaeological sites located in the Sado estuary, Lusitania province (Western Portugal), show evidence of an important amphorae production, mainly related to the Roman Tróia industrial centre of fish preserves. The chemical analysis of amphorae sherds found in Barrosinha, Bugio, Zambujalinho, Xarrouqueira and Vale da Cepa (Lower Sado) was performed by instrumental neutron activation analysis, and the mineralogical composition obtained by X-ray diffraction. The chemical results were compared with amphorae from the Herdade do Pinheiro production centre, also located in the Sado estuary. Application of several exploratory and discriminant techniques of multivariate statistical analysis using chemical data of Lower Sado amphorae allowed the characterization and differentiation of two reference groups, named Sado 1 and Sado 2. The geochemical patterns and the mineralogical composition of these groups indicate the use of two different raw materials, the selection of which appears to have been based on the proximity factor of the kilns. The amphorae produced in the Sado basin were differentiated from amphorae from the Gualdalquivir estuary (Villa Nueva, Cádiz, Spain) in Baetica province.     

The Use of the Bible by the Christian Human Rights Organizations Christian Solidarity Worldwide (CSW) and International Justice Mission (IJM)

Abstract

This paper explores the use made of the Bible by two Christian human rights organizations: Christian Solidarity Worldwide (CSW) and International Justice Mission (IJM), identifying the particular parts of Scripture appealed to, the hermeneutic adopted, and asks whether there are other resources in the Bible which they could use to inspire and inform their work. CSW with its focus on the persecuted Church most naturally draws its inspiration from the New Testament, especially the Epistles; whilst IJM whose work principally addresses other forms of injustice, makes greater appeal to the Old Testament. The biblical framework for IJM's work could be strengthened by a more sustained attention to Jesus' ministry as a model of human rights intervention and advocacy, by reflection on the significance of the Exodus as indicative of God's purposes for those who are oppressed, and by consideration of the book of James. CSW needs to integrate its commendable emphasis on Jesus' mission as exemplary for Christian human rights action with a holistic reading of the Bible and a greater exploration of the importance of the Church as the Body of Christ.     

Medieval land remediation of a quarry site at Wallingford,Oxfordshire, revealed by microfossil analysis

Abstract

Backfill material from a 12th- to13th-century quarry, north of Wallingford, south Oxfordshire, comprises sandy loam overlain by Cretaceous (early Cenomanian; Mantelliceras mantelli Macrofaunal Biozone) Glauconitic Marl Member, of the West Melbury Marly Chalk Formation as identified by its abundant, biostratigraphically useful, foraminifera and ostracods. A local outcrop source of the Glauconitic Marl Member, less than 1 km north of the quarry pit, is the likely provenance of this material, and a contemporaneous road, which was discovered adjacent to the medieval quarry by magnetometer surveys and archaeological excavation, would have aided its transportation, into the town via the North Gate. We hypothesise that the use of a calcareous marl to overlay sandy loam deposits probably encouraged land restoration when the quarried area was returned to pastoral agriculture.     

Provenance of prehistoric obsidian artefacts from Kul Tepe,northwestern Iran using X-ray fluorescence (XRF) analysis

Analysis by X-ray fluorescence of 53 obsidian artifacts the main source of obsidian for the workshops in Kul Tepe was Syunik but obsidian sources as far as west as the Lake Van region (Nemrut Da? and Meydan Da?) and as far north as Gutansar were also utilized. These new results indicate a broad network of trade and exchange.     

Food and social complexity at Çayönü Tepesi,southeastern Anatolia: Stable isotope evidence of differentiation in diet according to burial practice and sex in the early Neolithic

The identification of early social complexity and differentiation in early village societies has been approached in the past most notably through the evaluation of rituals and architectural layouts. Such studies could be complemented by an approach that provides data about everyday behaviours of individuals. We took 540 human and animal bone samples for stable carbon and nitrogen isotope analysis from the Neolithic site of Çayönü Tepesi in southeastern Anatolia. The inhabitants at this site chose to bury their dead in two different ways at different times during its occupation: beneath the floors of their houses, but also inside a public mortuary building known as the Skull Building. This variation provides an opportunity using isotope methods to test whether there was evidence for structuring of daily activities (diet in this case) that might serve to reinforce this change in burial practice. We show that when the inhabitants of Çayönü Tepesi changed their architecture and operated different burial practices in conjunction, this coincided with other aspects of behaviour including socially-constituted food consumption practices, which served to reinforce social identities.     

The use of white marbles for sculpture in Roman Gortyn (Crete) as revealed by archaeometric analyses

Gortyn was an important Cretan town from the late Archaic to the Hellenistic period and then became one of the provincial capitals of the Roman Empire. It controlled the whole of Crete and Cyrenaica and was a flourishing centre of trade and agricultural products in the first centuries of our era. In more than 100 years, many portions of the Greek and Roman town were unearthed under the supervision of the Italian Archaeological School of Athens and a considerable number of stone artefacts found, many of them made of imported marble since the local variety was grey and of poor quality. Statuary and other prestigious marble sculpted artefacts found in Gortyn were sampled and subjected to archaeometric examination (by way of optical microscopy in thin section, powder X-Ray diffraction and mass spectometry for the determination of the C and O isotopic ratio) in order to identify the quarries they came from. The results obtained from the analysis of several dozen white marble objects have indicated the use of a quite wide variety of species including Parian (from Lakkoi), Pentelic, Thasian (dolomitic and calcitic) and (occasionally) Proconnesian marbles. The first three, especially Pentelic, were used for most of the statuary.     

Early Renaissance Production Recipes for Naples Yellow Pigment: A Mineralogical and Lead Isotope Study of Italian Majolica from Montelupo (Florence)

The Naples Yellow pigment was apparently used for the first time by the Egyptians, as a glass‐colouring agent. Also known in the Mesopotamian and Roman cultures, the recipe was lost in Western Europe between the fourth and the 16th centuries ad . The recipe for the production of lead antimonate recently discovered in the ‘Codice Calabranci’ (second half of the 15th century) at Montelupo, a small town near Florence (Italy) known for its large‐scale ceramic production, possibly represents the very first evidence of the reintroduction of Naples Yellow in Western Europe after a long period of absence. The major‐element composition of the lead antimonate pigment in the Montelupo ceramics of the 15th and 16th centuries is in accordance with the ‘Codice Calabranci’ recipes. Lead isotope analyses indicate that the lead used to produce the yellow pigments and the underlying glaze of the Montelupo majolica did not come from the Tuscan mining districts, but was possibly imported via Venice from more distant lead sources in Turkey.     

The 74 ka Toba super-eruption and southern Indian hominins: archaeology,lithic technology and environments at Jwalapuram Locality 3

Hominins living in southern India 74,000 years ago faced a deteriorating environment, as the global climate moved from interglacial into full glacial conditions. At the same time, South Asian populations witnessed the widespread deposition of tephra from the Sumatran Toba super-eruption, the largest explosive volcanic event of the past two million years. Here we report new data on the lithic technology and environmental context for a southern Indian site with hominin occupation in association with Toba tephra deposits: Jwalapuram Locality 3 in the Jurreru Valley. Sedimentological and isotopic studies demonstrate that a cooling trend was in effect in this part of southern India prior to the eruption, and that thick deposits of ash in the Jurreru Valley supported grassland communities before more wooded conditions were re-established. Detailed technological analyses of an expanded lithic sample from Locality 3 suggest cultural continuity after the eruptive event, and comparisons with lithic core technologies elsewhere indicate that Homo sapiens cannot be ruled out as the creator of these Middle Palaeolithic assemblages.     

SEM-EDS characterization of western Mediterranean obsidians and the Neolithic site of A Fuata (Corsica)

During the Neolithic, obsidians of the Monte Arci (Sardinia) volcanic complex were by far more used in the northern Tyrrhenian area than those of the three other source-islands (Lipari, Palmarola, Pantelleria) in the western Mediterranean. It is shown that merely determinations of content for six major elements with a scanning electron microscope by energy dispersion spectrometry (SEM-EDS) are sufficient to distinguish the four types of Monte Arci obsidians. Because of the compositional similarities between these obsidian types, a multivariate analysis is recommended in provenance studies. Although SEM-EDS, electron microprobe-wavelength dispersion spectrometry (EMP-WDS) and particle induced X-ray emission (PIXE) give essentially concordant results in the determination of these six element contents, subtle technique-related biases prevent the combination of SEM-EDS, EMP-WDS and PIXE data on source samples for provenance purposes. An SEM-EDS test-study reveals the first occurrence of obsidians of Lipari for the A Fuata Middle to Late Neolithic site of NW Corsica (north of Sardinia), in addition to the usual Monte Arci obsidians. Similar to EMP-WDS, the SEM-EDS technique requires only millimeter-sized fragments.     

Ochre Provenance and Procurement Strategies During The Middle Stone Age at Diepkloof Rock Shelter,South Africa

Usually referred to in archaeological contexts simply as ‘ochre’, ferruginous rocks were commonly used during the Middle Stone Age (MSA) in South Africa. While ochre use by early modern humans has often been interpreted as reflecting complex behaviours, related procurement strategies and selection criteria remain poorly documented. Eight ochre sources from the surroundings of Diepkloof rock shelter in South Africa and 28 ochre pieces from the site's MSA levels were studied by XRD, ICP–OES and ICP–MS. Mineralogical and geochemical data demonstrate that ochre was both locally procured and transported to the site from more distant sources. Here, we investigate the reasons underlying the choice of particular local and non‐local ochre sources exploited at Diepkloof, emphasizing differences in their physico‐chemical properties. Regardless of the motivations behind ochre selection, our data shed new light on the behavioural complexity of MSA societies and suggest that ochre procurement strategies may be independent of subsistence concerns.     

Persistent deathplaces and mobile landmarks: The Holocene mortuary and isotopic record from Wadi Takarkori (SW Libya)

Recently, a new program of territorial study was launched in the area of Wadi Takarkori (Wadi Takarkori Project, hereafter WTP), located in south-western Libya at the border with Algeria in a strategic position between the Tassili and Acacus Mountains. The core of this program was the excavation of a rock shelter together with the systematic mapping and selected excavations of stone structures in the wadi area, mainly tumuli, a typical Saharan feature.
