THE CHARACTERIZATION OF PAINTS AND WATERPROOFING MATERIALS FROM THE SHIPWRECKS FOUND AT THE ARCHAEOLOGICAL SITE OF THE ETRUSCAN AND ROMAN HARBOUR OF PISA (ITALY)*

This work presents the results of a diagnostic survey on the shipwrecks from the archaeological site of the ancient harbour of San Rossore (Pisa, Italy). The original waterproofing, caulking and painting materials were characterized by Fourier transform infrared spectroscopy (FTIR), gas chromatography – mass spectrometry (GC–MS), energy‐dispersive X‐ray microanalysis (EDX) and X‐ray diffraction (XRD). The major constituents of the waterproofing and caulking materials detected on the planks were tricyclic abietanes showing a high degree of aromatization. These compounds are indicative of a pitch obtained from the wood of trees of the Pinaceae family. The analysis of the organic components of the paint samples revealed diterpenoid acids characteristic of Pinaceae resins together with linear long‐chain alcohols and fatty acids, highlighting the presence of beeswax. Noticeably, the characteristic odd carbon number alkanes that are normally present in beeswax were not detected. The EDX and XRD analyses showed that hematite, calcite, cerussite and kaolinite were employed as pigments to paint the ships’ hulls.     

Intimate Mediations of For‐Profit Conservation Finance: Waste,Improvement, and Accumulation

How to understand the marriage between accumulation and conservation? The paper draws from extensive research into one value chain, from the advisor in New York City to a wildlife‐friendly cattle business in Kenya. Making this enterprise return in money requires intimate and relentless efforts to transform wasteful conduct across a range of institutions and people; we focus on the attempted production of NGO economicus, homo economicus plus, and bos Taurus economicus. Drawing from feminist and postcolonial theorists of capitalism, we emphasise how green capitalist value production does not always hinge on extinguishing other‐than‐capitalist‐social relations but rather attempts to mobilise and harness such differences, including non‐profit‐seeking values, logics and relations. The paper concludes by reflecting on the temporal challenges facing for‐profit conservation finance, including those posed by previous regimes of accumulation that it relies on but also wants to overcome.     

The production and technology of glazed ceramics from the middle ages,found in the saepinum territory (Italy): a multimethodic approach*

A collection of ceramics from the Middle Ages found in Altilia and Terravecchia (the Saepinum area, Campobasso, Italy) were characterized by using different mineralogical analyses to investigate their provenance and production techniques. The body ceramic was investigated using Rietveld phase analysis of X‐ray powder diffraction patterns, X‐ray fluorescence spectrometry and scanning electron microscopy. The chemical compositions of the coatings were measured by scanning electron microscopy and their mineralogical compositions were determined using a particular technique of X‐ray small‐angle scattering (SAS) optimized for studies of thin films. Moreover, the material used for decoration was studied using micro‐Raman spectroscopy. The archaeometric results confirmed the distinction into two different ceramic classes, already individuated from archaeological analysis: the Altilia objects belong to the protomajolica class, whereas the objects from Terravecchia are RMR (ramina‐manganese‐red) ceramics. A comparison between the chemical and mineralogical compositions of good‐quality ceramic objects and those of waste products indicated local production of the ceramics. A sharp distinction was found in the chemical composition of the coatings: the Altilia products have tin‐opacified lead glazes, while the Terravecchia ones have transparent high‐lead glazes. Among the Altilia products, the unsuccessful process that produced a large quantity of discarded materials was attributed to the high lead content of the glazes. In fact, the principal advantage of the high lead content was to make the preparation and application of the glaze suspension easier, but the risk of reduction of lead oxide to metallic lead was greatly increased. Using micro‐Raman spectroscopy, the following minerals were identified as pigments: pyrolusite for the dark colour, malachite for green, lepidocrocite for yellow and hematite for red.     

A Multidisciplinary Approach to the Study of Archaeological Mortars from the Town of Ammaia in the Roman Province of Lusitania (Portugal)

The Roman town of Ammaia (in Marvão Region) is considered one of the most important recent findings of the Roman presence in Portuguese territory. It was settled in Republican times and abandoned in the seventh century. In this research, 17 masonry mortars and renders from the West Tower (South Gate), the residential area near the West Tower, the macellum, the peristylium, the public bath building, the podium of the temple and the portico of the forum were analysed. The methodology of chemical, mineralogical and microstructural characterization has involved several complementary techniques, including stereomicroscopy, X‐ray diffraction, thermal analysis and scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy. The results indicate that the mortars from the beginning of the town's edification were mainly composed of soil (clays). Later, during the main Roman building period, mortars were composed using a calcitic binder and the mortar composition varied according to their use and function. The samples from a period subsequent to the Roman occupation are based on a dolomitic binder. From the present study, relevant information has been acquired about the technological evolution of Roman construction in Ammaia, the historical context of the archaeological structures and guidelines for the conservation and restoration of mortars.     

Vegetation,land, and wood use at the sites of Bat and Al‐Khashbah in Oman (fourth–third millennium BC)

About 4200 charcoal fragments have been identified from the fourth‐ to third‐millennium BC archaeological sites of Bat and Al‐Khashbah in order to gain an understanding of plant resources available at the sites. Acacia sp., Ziziphus sp., and Tamarix sp. were the main taxa identified at both sites and indicate a similar vegetation composition as today. Phoenix sp. (date palm) charcoal also has been found at both sites. Whereas the cultivation of date palm for the 2700–2300 BC layers from Bat was likely, given other circumstantial evidence (i.e. local cereal cultivation and floodwater irrigation), it is unclear whether date palm was cultivated at Al‐Khashbah. Especially for the older periods (3300–2700 BC) it is possible that nomadic pastoralists were exploiting and/or managing wild date palms. The find of Avicennia marina at Al‐Khashbah indicates long‐distance contacts with the coast.     

First large‐scale provenance study of pigments reveals new complex behavioural patterns during the Upper Palaeolithic of south‐western Germany

The use of red iron‐based earth pigments, or ochre, is a key component of early symbolic behaviours for anatomically modern humans and possibly Neanderthals. We present the first ochre provenance study in Central Europe showing long‐term selection strategies by inhabitants of cave sites in south‐western Germany during the Upper Palaeolithic (43–14.5 ka). Ochre artefacts from Hohle Fels, Geißenklösterle and Vogelherd, and local and extra‐local sources, were investigated using neutron activation analysis (NAA), X‐ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that local ochre sources were continuously and systematically accessed for c.29 500 years, with periodic events of long‐distance (about > 300 km) ochre acquisition during the Aurignacian (c.35–43 ka), suggesting higher mobility than previously suspected. The results reveal previously unknown long‐term, complex spatio‐temporal behavioural patterns during the earliest presence of Homo sapiens in Europe.     

Taphonomy and zooarchaeology of the Upper Palaeolithic cave of Dzudzuana,Republic of Georgia

We present the results of a detailed taphonomic and zooarchaeological study of the faunal remains from the Upper Palaeolithic layers of Dzudzuana Cave, Republic of Georgia. This study presents the first carefully analysed Upper Palaeolithic faunal assemblage from the southern Caucasus and thus serves as a significant point of reference for inter‐regional studies of Upper Palaeolithic subsistence in Eurasia. A series of intra‐site taphonomic comparisons are employed to reconstruct the depositional history of the bone assemblages within the different occupational phases at the site and to investigate subsistence, meat procurement and bone‐processing strategies. Caucasian tur (Capra caucasica), aurochs (Bos primigenius) and steppe bison (Bison priscus) were the major prey species throughout the Upper Palaeolithic. Their frequencies do not change significantly over time, and nor does bone preservation vary by layer. The assemblage is characterised by significant density‐mediated biases, caused by both human bone‐processing behaviours and in situ post‐burial bone attrition. Bone marrow extraction produced large numbers of unidentified bone fragments, many exhibiting green bone fractures. The density and size of bone assemblages and the extent of fragmentation indicate that Dzudzuana Cave was repeatedly occupied by Upper Palaeolithic foragers over many years. Skeletal part representation and butchery marks from all stages of carcass processing suggest that prey occasionally underwent field butchery. Intra‐site taphonomic comparisons highlight uniform patterns of cultural and economic behaviours related to food procurement and processing strategies. Copyright © 2007 John Wiley & Sons, Ltd.     

Confirmation of the presence of Mycobacterium tuberculosis complex‐specific DNA in three archaeological specimens

This journal published the first reported identification of Mycobacterium tuberculosis complex (MTB) DNA in ancient human remains but concerns were raised about the article two years after publication. These were based on methodology which, in the field of ancient DNA, was still developing. Here we present a re‐examination of the 1993 research conducted on three specimens which exhibited palaeopathologies indicative of tuberculosis. The specimens were: an ulna from pre‐European‐contact Borneo, a spine from Byzantine Turkey, and a lumbar‐sacral spine from 17th century Scotland. There was insufficient material to permit re‐examination of all of the original samples. The earlier results were confirmed in two independent laboratories using different methodologies. MTB DNA complex‐specific DNA amplicons were obtained, and sequenced in both laboratories, in a re‐analysis of samples which supported the earlier findings.

Textural and isotopic evidence on the fluid source and transport mechanism of antitaxial fibrous microstructures from the Alps and the Appalachians

The source of fluid‐forming veins is of great importance in order to understand the hydraulic system acting in the earth's crust. The study of syntectonic antitaxial veins is one of the few methods by which the opening history can be deduced from rocks, and thus these veins are of primary importance in determining rock kinematics. Antitaxial veins were taken from black shales in two different tectonic settings in the Helvetic Alps, Switzerland, and the Taconic Appalachians, New York State. These syntectonic extension veins are regularly spaced and are oriented sub‐normal to bedding. The vein microstructure displays a symmetry around the median line in the centre of the vein, and a symmetry in cathodoluminescence banding parallel to the vein–wall interface, which suggests transport along bedding‐parallel dissolution planes from both vein‐walls. Antitaxial veins nucleated in transgranular fractures, but evidence for ongoing multiple crack‐seal increments is lacking; rather, veins grew continuously keeping close contact to the vein‐wall. Radiogenic ⁸⁷Sr/⁸⁶Sr ratios are higher in the surrounding matrix than in the vein, and higher than the corresponding seawater data in all samples. Variations are small and calcite in both the vein and the host rock were derived from the same source of fluid in the Helvetic samples. Mass balance of Sr suggests that the amount of calcite is too small in the surrounding host rock to be derived locally. Stable oxygen compositions are heavier in the host rock than in the veins, with overall low variation in both δ¹⁸O and δ¹³C values in the Mesozoic Helvetic samples. Data point to a rock‐buffered system, the precipitate most likely derived from an external source. The lower Palaeozoic Appalachian veins have lesser δ¹⁸O values than the host rock, similar to the Helvetic veins. Radiogenic ⁸⁷Sr/⁸⁶Sr data and a large heterogeneity in stable isotope values indicate an open system. Microstructural and isotopic evidence suggests that the antitaxial veins were formed by pervasive fluid flow, with the solute at least partly derived from an external source.     

Infancy and childhood in the pre‐Columbian North American Southwest–first results of the palaeopathological investigation of the skeletons from the Grasshopper Pueblo,Arizona

Infant and child skeletons (n = 369) from the pre‐Columbian Grasshopper Pueblo site in east‐central Arizona (US) dating from the 14^th century AD were examined macroscopically and with low‐power microscopy. They were studied as a representative example of a typical Mogollon community with respect to frequencies of deficiency and inflammatory diseases. First results revealed very poor living conditions, which are characteristic for this time period in the North American Southwest because of lack of food due to climatic and political changes. Thus, non‐specific stress indicators were frequently observed. In the group of deficiency diseases, anaemia was found in more than 50% of individuals, and in the group of inflammatory diseases, meningeal irritations were diagnosed in more than 70%.

New Equations for the Size Reconstruction of Sturgeon from Isolated Cranial and Pectoral Girdle Bones

Measurements on cranial and pectoral girdle bones of 56 museum specimens of modern sturgeon (Acipenser sturio and A. oxyrinchus) were used for the establishment of regression equations allowing back‐calculation of size from isolated sturgeon remains. Different curve fittings (power, linear, logarithmic and exponential fit) were modeled to retain the most accurate regression. These were then applied to archaeological sturgeon remains (A. sturio/A. oxyrinchus) from Vlaardingen, a Dutch late Neolithic settlement. The back‐calculated lengths obtained on the archaeological remains all stayed within the known size ranges of the two species and allowed making inferences on the possible place of capture of the fish.

The exploitation of marine resources at Saruq al‐Hadid: Insights into the movement of people and resources in Bronze and Iron Age south‐eastern Arabia

Marine resources were an integral and consistent component of subsistence strategies employed in south‐eastern Arabia throughout late prehistory. Of particular interest is the movement of these resources from the coast to interior sites and the implications of this movement for transhumance and trade in the region during this period. Marine species were frequently identified in the faunal assemblage from the inland site of Saruq al‐Hadid, dating from the Bronze Age to Early Iron Age (c.2000–c.800 BCE). This included marine fish species, along with two cormorant species (Phalacrocorax sp.) and several fragments of dugong (Dugong dugon). Twenty‐seven families of marine shell were also identified in the remains recovered from the site. The presence of these remains at this inland site demonstrates that resources were frequently moved from the coast to the interior throughout Saruq al‐Hadid’s occupation, indicative of their enduring significance in subsistence strategies employed at the site. This paper presents the results of zooarchaeological analysis of these remains and discusses the significance of their presence at Saruq al‐Hadid, with reference to subsistence, craft production and intra‐regional exchange during the Bronze and Iron Ages.     

Corporate Social Responsibility,Supply‐chains and Saami Claims: Tracing the Political in the Finnish Forestry Industry

At the heart of debate surrounding Corporate Social Responsibility (CSR) lies an inherent anxiety over the division of responsibility between states and corporations. Commonly taken for granted is a natural and a priori separation of government and market activities. This paper provides a critique of the conceptual division of responsibility between ‘state’ and ‘market’ actors, and explores the politically ambivalent roles of state financed companies in global CSR dialogues on the rights of Indigenous Peoples. It uses a case concerning logging on Saami reindeer herding territory, and explores a particularly Finnish articulation of CSR and supply‐chain management in the Finnish forestry and paper sector.     

Dwelling in the Sites of Finitude: Resisting the Violence of the Metaphysical Globe

Abstract: In this paper Martin Heidegger's notions about dwelling in the sites of finitude and “power‐free” (Macht‐los) “letting‐be” (Gelassenheit) are explored as fundamental possibilities for resisting the ontological violence posed by global capitalism, the planetary outcome of the metaphysical condition Heidegger calls the “machination” (Machenschaft). Beginning from the planetary machination—the emergence of the flexible and circularly functioning power of calculative intelligibility—resistance is understood ontologically and hence as a radical critique of power as a consummation of the history of the metaphysical constitution of being. The paper culminates in a discussion of Heidegger's view on the awakening of the “other beginning” of the abyssal “Event” of being, a groundless “time‐space‐play” capable of constituting an alternative modality of relations no longer based upon the calculative functions of power but upon groundless thought and non‐violent dwelling in the earth‐sites of finite being.     

Post‐CO2 injection alteration of the pore network and intrinsic permeability tensor for a Permo‐Triassic sandstone

The aim of this study was to determine the process–structure–property relationships between the pre‐ and post‐CO₂ injection pore network geometry and the intrinsic permeability tensor for samples of core from low‐permeability Lower Triassic Sherwood Sandstone, UK. Samples were characterised using SEM‐EDS, XRD, MIP, XRCT and a triaxial permeability cell both before and after a three‐month continuous‐flow experiment using acidic CO₂‐rich saline fluid. The change in flow properties was compared to those predicted by pore‐scale numerical modelling using an implicit finite volume solution to the Navier–Stokes equations. Mass loss and increased secondary porosity appeared to occur primarily due to dissolution of intergranular cements and K‐feldspar grains, with some associated loss of clay, carbonate and mudstone clasts. This resulted in a bulk porosity increase from 18 to 25% and caused a reduction in mean diameter of mineral grains with an increase in apparent pore wall roughness, where the fractal dimension, D_f, increased from 1.68 to 1.84. All significant dissolution mass loss occurred in pores above c. 100 μm mean diameter. Relative dilation of post‐treatment pore area appeared to increase in relation to initial pore area, suggesting that the rate of dissolution mass loss had a positive relationship with fluid flow velocity; that is, critical flow pathways are preferentially widened. Variation in packing density within sedimentary planes (occurring at cm‐scale along the ‐z plane) caused the intrinsic permeability tensor to vary by more than a factor of ten. The bulk permeability tensor is anisotropic having almost equal value in ‐z and ‐y planes but with a 68% higher value in the ‐x plane (parallel to sedimentary bedding planes) for the pretreated sample, reducing to only 30% higher for the post‐treated sample. The intrinsic permeability of the post‐treatment sample increased by one order of magnitude and showed very close agreement between the modelled and experimental results.     

A Portuguese East Indiaman from the 1502–1503 Fleet of Vasco da Gama off Al Hallaniyah Island,Oman: an interim report

Two Portuguese naus from Vasco da Gama's second voyage to India, left behind to disrupt maritime trade between India and the Red Sea, were wrecked in May 1503 off the north‐eastern coast of Al Hallaniyah Island, Oman. The ships, Esmeralda and São Pedro, had been commanded by da Gama's maternal uncles, Vicente and Brás Sodré, respectively. A detailed study and scientific analysis of an artefact assemblage recovered during archaeological excavations conducted in Al Hallaniyah in 2013 and 2014 confirms the location of an early 16th‐century Portuguese wreck‐site, initially discovered in 1998. Esmeralda is proposed as the probable source of the remaining, un‐salved wreckage.     

A Multidisciplinary Approach for the Archaeometric Study of Pozzolanic Aggregate in Roman Mortars: The Case of Villa dei Quintili (Rome,Italy)

This contribution focuses on the study of historical mortars from a Roman archaeological site known as Villa dei Quintili, a monumental villa located in the south‐eastern part of Rome (Italy). The study was carried out on 38 mortar samples, collected from several edifices within the complex. A multi‐analytical approach, including polarized optical microscopy, scanning electron microscopy coupled with energy‐dispersive system and laser ablation inductively coupled plasma mass spectrometry, was used to analyse the pozzolanic material used for the preparation of mortars. Data obtained on both major and trace elements were compared with the compositions of Pozzolana Rossa, Pozzolana Nera and Pozzolanella samples from the Alban Hills volcanic district, collected from a historic quarry nearby, as well as with literature data. The results of such a multidisciplinary approach allowed us to recognize the use of all three pozzolan types for the aggregate fraction of examined mortars from the Villa dei Quintili.     

Supporting food security for Indigenous families through the restoration of Indigenous foodways

Indigenous families are overrepresented among those within Canada who experience food insecurity. Studies have largely focused on northern populations, with less attention paid to southern and urban communities, including the social, cultural, and geographic processes that challenge food security. In this study, we present findings from a decade‐long community‐based study with the Southwest Ontario Aboriginal Health Access Centre (London, Ontario) to examine family perspectives related to the social determinants of food security. These topics were explored through qualitative interviews (n = 25) and focus groups (n = 2) with First Nation mothers with young children from the city of London, and a nearby reserve community. Interviewees from both geographies identified a number of socio‐economic challenges including household income and transportation. However, some interviewees also shed light on barriers to healthy eating unique to these Indigenous contexts including access issues such as a lack of grocery stores on‐reserve; loss of knowledge related to the utilization of traditional foods; and the erosion of community, familial, and social supports. Resolving these unique determinants of food security for urban and reserve‐based First Nation families will require a range of economic and culturally specific interventions, particularly those that support development and uptake of Indigenous foodways.     

Mammalian Microfaunal Remains from Khonkho Wankane (Late Formative Period), Mollo Kontu (Middle Horizon Period) and Pukara de Khonkho (Late Intermediate Period) in the Bolivian Altiplano

Paleoecological and taphonomic analysis of the mammalian microfauna from three Bolivian altiplano sites is presented: Khonkho Wankane [Late Formative period; number of identified specimens (NISP) = 1019], Mollo Kontu (Middle Horizon period; NISP = 610) and Pukara de Khonkho (Late Intermediate period; NISP = 165). The following species, all of which are present in this region today, were identified: Akodon boliviensis (Bolivian grass mouse), Andinomys edax (Andean mouse), Auliscomys sublimis (Andean leaf‐eared mouse), Cavia porcellus (guinea pig/cuy), Chinchilla chinchilla (chinchilla), Ctenomys leucodon (white‐toothed tuco‐tuco), Eligmodontia puerulus (Andean gerbil mouse), Galea musteloides (common yellow‐toothed cavy), Lagidium viscacia (vizcacha), Neotomys ebriosus (Andean swamp rat),and Oligoryzomys destructor (destructive pygmy rice rat). Some direct human involvement with the deposition of some of the larger species (Cavia porcellus, Chinchilla chinchilla, Ctenomys leucodon and Lagidium viscacia) was noted, although C. porcellus was identified only from a single element from Mollo Kontu. Most deposition was likely due to natural in‐burrow deaths and other natural attrition of these species. No significant shift in environment during the occupation of these sites was detected.
