THE ORIGIN AND GEOCHEMICAL CHARACTERIZATION OF RED OCHRES FROM THE TITO BUSTILLO AND MONTE CASTILLO CAVES (NORTHERN SPAIN)*

Ochres were the most common source materials for pigments used in Palaeolithic rock art paintings. This work analyses the petrographic and geochemical signatures of different ochre samples from outcrops inside Tito Bustillo Cave and the Monte Castillo Caves using the most common techniques (petrography, XRD, SEM–EDS and ICP–MS) in archaeological pigment characterization studies. The results obtained permit the identification and characterization of the different source ochre types and, furthermore, allow the establishment of mineralogical and geochemical proxies for the study of questions related to ochre characterization, formation processes and provenance.     

Ohio Hopewell Depictions of Composite Creatures: Part II–Archaeological Context and a Journey to an Afterlife

Abstract

Archaeological contextual analyses of four artifacts that depicted composite creatures and that were recovered from the Turner earthwork in southwestern Ohio are integrated here with a biological identification of the creatures' component animals and a survey of historic Woodland–Plains Indian knowledge about their roles in Woodland–Plains life (previously reported in this journal). Together, the three studies reveal that the creatures were likely employed in a ritual drama concerned with the welfare of recently deceased persons on their journey to an afterlife through underwater–underground realm(s), where they encountered the creatures. The location of the journey to an afterlife through Below realm(s) differs from that of nearly all historic Woodland–Plains Indians, who knew the journey to take place on the earth-disk or to occur by ascension. Implications of the ritual drama at Turner for some recent interpretive trends in Woodland archaeology are explored, including an overemphasis on “world renewal” as the primary motivation behind Ohio Hopewell ceremonialism, the scarce attention given to eschatological matters, and the misleading notion that all agentive behaviors, including mortuary rites, are political.     

Partisan Identification and Attitudes to Big Versus Small Government in Australia: Evidence from the ISSP

In Australian politics, Labor has traditionally been thought of as the party of big government and the Liberals the party of small government. Drawing from evidence from the 1985, 1990, 1996 and 2007 International Social Survey Programme (ISSP) Role of Government surveys, this article examines public opinion in relation to the role of government and how public attitudes towards government differ according to party identification. It is reasonable to expect that Labor Party identifiers would be more supportive of big government, but there is little empirical evidence to support this expectation. This article shows that citizens' attitudes still accord with the Labor–Liberal/big–small government dichotomy and shows partisan identification to have an enduring effect on attitudes towards the role of government, net of other factors.     

Neolithic Adhesive from a T‐shaped Ornamental Element Excavated at Site 14 at Kowal,Kuyavia, Central Poland

We conducted an identification of a substance isolated from a T‐shaped ornamental element excavated from a Globular Amphora Culture tomb at the Kowal 14 archaeological site in Poland. ¹⁴C dating indicated 4105 ± 35 bp (POZ‐21912) and 3990 ± 50 bp (POZ‐21910). Analytical methods such as SEM–EDS, XRD and FT–IR were applied to study the origin of its structure. The results of instrumental analysis and the archaeological context indicate that the adhesive substance investigated consists mainly of calcium carbonate (calcite, 78–88%), silica dioxide (quartz), sodium aluminium silicate (albite) and potassium aluminium silicate (microcline). The material might be a man‐made, mineral adhesive, a kind of lime mortar. The object is considered as the oldest European finding of this type outside the Mediterranean Basin. It provides evidence for the use of the lime calcination process in Central Europe as early as in the Late Neolithic, for which there were—up to now—no convincing premises.     

Skeletal evidence for hyperparathyroidism in a 19th century child with rickets

The skeletal remains of a child aged 2.5–3.5 years, recovered during archaeological excavations at the churchyard of St Martin's Church, Birmingham, UK, were examined using gross observation, radiography and scanning electron microscopy. Lesions suggestive of the presence of rickets and of secondary hyperparathyroidism were found. This appears to be a first report of secondary hyperparathyroidism in response to rickets in a palaeopathological specimen. The potential of microscopic examination of bone for interpreting disease processes is emphasised. Copyright © 2006 John Wiley & Sons, Ltd.     

230Th/U dating of the Trojan ‘water quarries’

We determined the ²³⁰Th/U ages of individual calcite layers that grew on the walls of artificial water‐supply tunnels (‘water quarries’) at Troy/Ilios by using thermal ionization mass spectrometry. The oldest age of overgrowth being 4350 ± 570 years, the tunnels must have been built a short time earlier, during the archaeological period Troy I–II. The tunnels were also used during Troy VI–VII (1700–1150 bce, a period that includes the date of the supposed ‘Trojan War’), in Homeric times (c. 720 bce) and in the Roman period. These findings add strong support to the identification of the water quarries with a natural phenomenon and Anatolian deity known in Hittite texts of the second millennium bce as KASKAL.KUR, a term denoting subsurface water systems. Consequently, they reinforce the view that Troy in the second millennium bce was Anatolian in character. In this way, the findings are also consistent with the identification of (W)Ilios with Wilusa, a city attested to in Hittite historical texts.     

Identification of the magnetospheric cusp and cleft using Pc1–2 ULF pulsations

Geomagnetic pulsations in the 0.1–2.5 Hz (Pc1–2) range recorded over 12 quiet summer days at six Antarctic stations between −62.3 and −80.6° invariant latitude were examined in order to map the spatial and temporal distribution of spectral characteristics. Ionospheric particle signatures associated with the magnetospheric cusp and boundary layer were deduced for three of these days using ground riometer, magnetometer and ionosonde measurements, and in-situ ionospheric particle data. Comparison with the magnetic pulsation data shows that specific Pc1–2 emissions are associated with these regions. Within the cusp, intense unstructured ULF noise in the 0.15−0.4 Hz range is observed. Less intense waves of this type are seen near the cusp location on mantle and plasma sheet boundary layer flux tubes. These emissions are quite distinct from the discrete, structured and narrowband emissions seen equatorward of the cusp. Whereas past discussions of cusp and cleft identification have usually focused on optical or satellite data, we conclude that ground-based observations of Pc1–2 pulsations can provide a more convenient, although less precise, monitor of high latitude features.     

Congenital Syphilis in the Archaeological Record: Diagnostic Insensitivity of Osseous Lesions

The paucity of convincing evidence for congenital bone lesions of syphilis in the archaeological record led to study of the human remains from the Buffalo site in West Virginia, dated at 550—650 years BP. The diagnosis of syphilis (venereal) in adults was based on previously validated population criteria for the recognition of syphilis and its distinction from among the other treponemal diseases. Among the 151 juveniles (23.3 per cent of the total series), only one had macroscopic evidence of periosteal disease. The low frequency of recognizable osseous stigmata characteristic of congenital syphilis, combined with the conspicuous absence of pathognomonic dental lesions, make such periosteal lesions insufficiently sensitive criteria for the identification of syphilis in the archaeological record. © 1997 by John Wiley & Sons, Ltd.     

First absolute dating of Andean hunter-gatherer rock art paintings from North Central Chile

We report the first absolute dating for rock paintings by Andean hunter-gatherer groups. Analysis by Raman spectrometry of remains of black paintings from the center-north of Chile (30° lat. S) allows for the identification of carbon as the raw material. Radiocarbon dating situates these paintings between 1623–1431 BCE and 80–240 ACE, dates that are supported by other lines of independent evidence. These results are consistent with proposals that suggest the appearance and popularization of rock art in various places in the Andes for the temporal transect of 3000–1000 BCE. Finally, these new datings are added to the scant corpus of absolute dates for rock art that exist in South America.     

Subsistence and Settlement Correlates of Treponemal Disease: Temporal Patterns in Pre‐Columbian East Tennessee

After ca 1000 BC , coinciding with the transition to sedentism, tertiary stage treponemal disease apparently becomes osteologically pervasive in pre‐Columbian North America. However, varying interobserver treponemal disease diagnostic thresholds, sampling error and the possibly ecosensitive nature of the pre‐Columbian nonvenereal treponemal disease variants (i.e. yaws and treponarid) prevents subsistence‐settlement pattern from becoming a reliable predictor of treponemal disease prevalence. This is particularly true of later prehistory with the transition from horticulture to intensive, maize‐based agriculture. To address whether treponemal disease visibility does vary across this specific subsistence‐settlement threshold, subadults (4+ years of age) and adults from 11 late prehistoric sites (N = 997) from the same geographic area of East Tennessee were sampled for the presence of treponemal disease. Six sites (N = 279) primarily date to the Late Woodland period (AD 700–900) and culturally belong to what is referred to as the Hamilton mortuary complex. The sample is archaeologically characterised as horticulturalist with presumably a dispersed farmstead or hamlet settlement pattern. Six sites (N = 718) date to the Late Mississippian (AD 1300–1550, Dallas phase) and are maize‐intensive agriculturalists with a large, aggregate village settlement pattern. The sites were examined using three different levels of treponemal disease diagnostic confidence. Treponemal disease raw frequency does indeed differ across the levels of diagnostic confidence between the total Late Woodland horticulturalist sample (4.3–5.5%) and total Late Mississippian maize agriculturalist sample (5.4–6.5%). The meaning is complex as the Dallas phase sample may have a socially segregated elite; the mound‐interred (1.8%) relative to the village‐interred (6.1–7.4%) exhibited significantly fewer cases of treponemal disease. Tentatively, treponemal disease visibility does appear to co‐associate with sedentism and perhaps (if the mound‐interred Dallas individuals are elites) also aggregated settlement.

Separating Sheep (Ovis aries L.) and Goats (Capra hircus L.) Using Geometric Morphometric Methods: An Investigation of Astragalus Morphology from Late and Final Bronze Age Central Asian Contexts

Many qualitative and quantitative methods for the separation of sheep and goat bones are based upon Middle Eastern, Mediterranean and European specimens. However, these methods may not be as applicable in other geographical contexts due to regional morphological variation. In order to address this, both traditional and geometric morphometric methods were applied to sheep, (Ovis aries L.) and goat (Capra hircus L.) astragali from archaeological sites from Kazakhstan dating to the Late and Final Bronze Age (1900–900 bce ). This exploratory research confirmed that qualitative features remained useful for distinguishing between species, while traditional morphometric methods were unable to conclusively support the field identification of species. Geometric morphometric methods found significant morphological differences between species and confirmed group membership while exploring specific qualitative features that were effective in distinguishing between sheep and goat in Central Asian contexts.

DISCOVERY AND CHARACTERIZATION OF AN UNKNOWN BLUE‐GREEN MAYA PIGMENT: VESZELYITE*

Blue‐green mosaic and polychrome masks and funerary offerings from the royal tombs of Calakmul, Mexico, were analysed by scanning electron microscope equipped with energy dispersive X‐ray spectroscopy (SEM‐EDS), X‐ray diffraction (XRD), and particle induced X‐ray emission (PIXE). This led to the first identification of the use of veszelyite, a rare hydrated copper‐zinc phosphate, as green pigment. Analyses of a geological sample of this mineral have been done to confirm the characterization of this Mayan pigment, which might help determine pre‐Columbian trade routes of precious and luxury objects in the ancient Maya Classic period (ad 250–800).     

Paget's disease in pre‐contact Florida? Revisiting the Briarwoods site in Gulf coast Florida

This report presents results of a reanalysis addressing the presence of Paget's disease (Osteitis deformans) in the pre‐contact Safety Harbour Briarwoods site (8PA66), a burial mound in Pasco County along Gulf coast Florida, dating around 1000–1500 AD. Due to the paucity of published histological and radiological analyses as well as the suspect nature of this Paget's disease report, a new study was conducted. The diagnosis was suspect for three reasons. First, the original diagnosis was based on five skeletal fragments from five different burials making the results questionable. Secondly, Paget's disease is very similar to treponemal disease and can possibly be misdiagnosed. The characteristic histological mosaic pattern found in Paget's disease provides the most definitive differential diagnosis. Thirdly, Paget's disease is found primarily in European populations and this is a pre‐contact site. Histological sections from the suspected Pagetic bones were analysed for the presence of the mosaic pattern. Macroscopic and microscopic analyses were unable to support or deny the presence of Paget's disease due to the fragmentary nature of the skeletal elements as well as extensive diagenesis resulting from exposure to the environment. The presence of Paget's disease could not be confirmed or refuted at Briarwoods due to extensive taphonomic damage. However, it is suggested that the presence of treponemal disease should be investigated because although not originally reported, the presence of saber‐shin tibiae consistent with this disease are present at this site.

Diagenesis and elemental geochemistry under varying reservoir oil saturation in the Junggar Basin of NW China: implication for differentiating hydrocarbon‐bearing horizons

In this paper, we attempt to differentiate hydrocarbon‐bearing reservoir horizons of the Junggar Basin of NW China based on the characteristics of diagenesis and associated elemental geochemistry. Reservoirs at this site have varying levels of oil saturation that correlate with the degree of dissolution in minerals (e.g., calcite and feldspar). Four different horizons with varying diagenetic mineral assemblages were observed, including (i) kaolinite‐rich, oil‐dominated horizons, (ii) kaolinite–pyrite–hematite‐rich, oil–water‐dominated horizons, (iii) siderite–chlorite‐rich, water‐dominated horizons, and (iv) chlorite‐rich horizons with negligible hydrocarbon production. The mean MnO content of the representative diagenetic mineral (e.g., calcite) in each of the above horizons is >2.5, 2.0–2.5, 1.5–2.0, and <1.0 wt%, respectively. We propose that the above methodology can be used for the identification of reservoir hydrocarbon‐bearing horizons. We argue that the indicators presented here can be applied in oil exploration across the Junggar Basin.     

Application of Quantitative Mineralogical Analysis in Archaeological Micromorphology: a Case Study from Barrow Is., Western Australia

This study assesses the use of the Tescan Integrated Mineral Analyser (TIMA) platform, which integrates scanning electron microscopy—energy dispersive spectroscopy (SEM-EDS) chemical analysis with mineral identification software, to quantitatively determine the mineralogical composition of sediments in archaeological research. Ten samples, spanning 50,000 years of sedimentation, were examined from archaeological excavation profiles in the Boodie Cave, Barrow Island, Western Australia. TIMA mineral abundance data show a gradual change from a polymineralogic quartz-rich assemblage from ~50–12 ka to a more simple carbonate-dominate assemblage from the terminal Pleistocene. This trend is consistent with a decreasing contribution of reworked terrestrial siliciclastic sediments derived from the mainland and an increase in carbonate sediments of marine derivation, as the exposed coastal plain become submerged during post-glacial sea-level rise. SEM-EDS analysis has also provided empirical data on cultural materials, mainly bone and shell fragments that similarly reflect the increasing contribution of marine fauna into the Holocene sediments. Particularly useful is the ability of mineral mapping function of the TIMA outputs to help distinguish 16 sub-units representing sections of the main nine stratigraphic units, including at least three contiguous midden events. The SEM-EDS data indicate that the redeposited sediments were derived from the overlying midden unit, with layering reflecting differential settling of mineral phases. This study demonstrates that automated mineralogy studies using TIMA can clearly aid the identification of provenance and processes within archaeological sediments and soils.     

Husbandry practices and livestock dung at the Numidian site of Althiburos (el Médéina,Kef Governorate,northern Tunisia): the phytolith and spherulite evidence

Recent excavations at Althiburos, northern Tunisia, have shown the existence of permanent pre-roman occupations in the central area of the urban settlement. Significantly, the site has been found to contain one of the most complete Numidian sequences, spanning from the Early Numidian (at least from the 10th–9th century BC) to its final stage. Research at the site addresses questions related to the identification of settlement patterns at this time.The combined study of phytoliths and spherulites recovered from well defined archeological contexts at the site have provided new data for identifying husbandry activities carried out by the ancient Numidian populations. The results show that there is abundant evidence for both cooking and processing cereals, primarily from common or bread wheat (Triticum aestivum). Also significantly, was the abundance of faecal spherulites in certain areas of the site, indicative of dung accumulation. The correlation between large amounts of spherulites and rich phytolith sediments in specific contexts, suggested that grasses were brought to the site or consumed offsite and deposited onsite as livestock dung or dung-products. The identification of dung accumulations in the site raises questions about the diversity of economic practices developed by Protohistoric communities in northern Africa. Future research questions regarding such dung rich layers will also be examined.     

Archaeometric analysis of the ‘greco scritto’ marble slabs from the Edificio dei Triclinii at Murecine (Pompeii,Italy)

This paper presents the results of the archaeometric analysis of the greco scritto marble slabs from the Edificio dei Triclinii, an inn or statio negotiatorum discovered at Murecine in Pompeii’s suburbs in 1999–2000. A total of 14 samples were collected and subjected to standard X-ray diffraction (XRD), optical microscopy (OM) on thin sections and stable isotope ratio analysis (SIRA) to assess the stone’s identity and provenance. The results of this study substantiate the hypothesis (already put forward and based on a macroscopic identification by Perna and Scognamiglio) that the stone originates from the Hasançavuşlar quarries near Ephesus in Asia Minor, and represent the first step towards a systematic contextual and geochemical study of Ephesian greco scritto in Roman contexts and its respective contribution to the Roman stone trade.     

New data on relevant ancient Egyptian wooden artifacts: Identification of wooden species and study of the state of conservation with multidisciplinary analyses

Wood species identification and characterization of its weathering processes are crucial steps in the scientific approach of conservation of wooden cultural heritage. Many precious wooden objects of ancient Egypt are largely present in museums, nevertheless relatively little information is available concerning the nature of timber used and on their status of conservation. To address this gap, the wooden species of three relevant archaeological wood objects (statue, box, and coffin) arising from different Egyptian archaeological sites dated from the Old Kingdom (2,686–2,181 BC) to New Kingdom (1,550–1,069 BC) were deeply studied. Five hardwood and softwood species were identified belonging to Tamarix mannifera, T. gennessarensis, Ficus sycomorus, Vachellia nilotica, and Cedrus sp. Such data confirmed the recurrence of Vachellia and Tamarix among the most common timbers found in ancient Egypt. Scanning electron microscope, Fourier transform spectroscopy, and synchrotron x-ray radiation diffraction were conducted to evaluate the archaeological wood deterioration. The formation of microcracks, biological degradation patterns (fungal colonization), or chemical characterization (accumulation of salts on and in-between wooden cells) were detected. SEM micrographs showed the presence of fungal hyphae and conidial spores on the wooden cells. Significant changes in the chemical wood composition and decrease in the crystallinity index were detected.     

ANALYTICAL CHARACTERIZATION OF ROMAN PLASTERS OF THE ‘DOMUS FARINI’ IN MODENA*

The paper refers to the analytical characterization of Roman painted plasters dating back to the second century ad . The following techniques were used: optical microscopy (OM), scanning electron microscopy (SEM–EDS), micro‐Raman and Fourier transform infrared spectroscopies (µ‐Raman and FT–IR), X‐ray diffraction (XRPD), colorimetry and thermal analyses (TG/DTA). The investigation analysed the chemical composition and structure of the plasters, the chemical composition of the pigment layers, the use of binders and any chemical alteration of pigments as well as deterioration of the samples. Stratigraphic analysis of plasters allowed identification of their individual components, which proved helpful in finding out more about the mural painting technique employed.     

Did Children in Medieval and Post‐medieval Poland Suffer from Scurvy? Examination of the Skeletal Evidence

Late‐medieval and post‐medieval writings report that scurvy was a widespread condition in medieval and early historical Poland. Archaeological and historical data indicate that the diet of children was based on foods poor in vitamin C and contained small amounts of raw plant products. Also, historians emphasise that in medieval and post‐medieval Poland, there were seasonal fluctuations in food availability, frequently accompanied by poor harvests. Both resulted in long periods of poor nutrition, which affected children most severely. The aim of this study was to investigate skeletal manifestations of scurvy in subadult remains from medieval and post‐medieval Poland. Following standards described by Ortner and colleagues, anatomical sites pathognomonic of scurvy in subadults (<17 years) were assessed for abnormal porosity and hypertrophic bone among skeletons excavated from three sites: Ostrów Lednicki (dated to the 11th–14th centuries AD), Cedynia (10th–14th centuries AD) and Słaboszewo (14th–17th centuries AD). In total, 3.6% of all examined children were found to bear traces of vitamin C deficiency. The prevalence of scorbutic lesions was 4.5% for Cedynia, 2.6% for Ostrów Lednicki and 3.6% for Słaboszewo. The majority of affected children were less than 7 years of age. Scurvy was likely more widespread in the living populations than it appears from the calculation of skeletal markers, because some individuals might have recovered or died before obvious traces became apparent. Also, in some children, scurvy might not have reached an advanced stage, identifiable in the skeletal material. The prevalence of scurvy reflects not only dietary patterns but also food storage and preparation techniques adopted in the Polish territories during the Middle Ages, which contributed to low intakes of vitamin C.
