Treponemal Disease,Tuberculosis and Subsistence‐settlement Pattern in the Late Woodland Period West‐central Illinois

In later pre‐Columbian prehistory (post AD 1000), the adaptation and intensification of maize agriculture and its correlate of aggregate village settlement (i.e. Mississippianization) is temporally and geographically variable. In the Midwest, consequential to the florescence of the major ceremonial centre of Cahokia (AD 1050–1300), the Mississippi River Valley alluvial plain in Illinois, known as the American Bottom, became a core area of this subsistence‐settlement change. Much archaeological research has traced aspects of this transition in the Lower and Middle Illinois River Valley, but little is known outside of these areas. A skeletal sample from the remote hinterland area of the Upper Mississippi River in west‐central Illinois was examined for arguable paleopathological correlates of sedentism (treponemal disease) and Mississippianization (tuberculosis). The Schroeder Mounds (AD 900–1100) adult skeletal sample (N = 53) exhibited a high frequency of treponemal disease (13.2–15.1%). This result is consistent with paleopathological literature linking a 9+ % pre‐Columbian North American prevalence with sedentism, challenging archaeologically based inferences that the hinterland was occupied by mobile forager‐horticulturalists. A hallmark of Mississippianization is the presence of diagnostic cases of tuberculosis. No cases were observed in the Schroeder sample, suggesting a pre‐Mississippian subsistence‐settlement pattern.

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.

ROCK ART SITES IN JAMAICA AND THEIR ETHNOGRAPHIC INTERPRETATION

26 sites with Pre‐Columbian (Taíno) rock art are known in Jamaica, most with petroglyphs only, but there are four with painted images, and three of these are discussed: Mountain River Cave, Potoo Hole, and Spot Valley Cave. In addition, an account is given of the Warminster rock shelter, which has petroglyphs described as among the best remaining in Jamaica. Spot Valley Cave was newly surveyed in 2005, with the help of the Jamaican Caves Organization, and in the same year a rescue operation to restore the Warminster petroglyphs was carried out, in cooperation with Dr Johannes Loubser. Comparisons are made, where appropriate, to Taíno artefacts in different materials, and also to Pre‐Columbian images on other islands in the Caribbean, notably Puerto Rico. The interpretation of the Taíno images, in Jamaica and elsewhere, relies to a considerable extent on the “Account of the Antiquities of the Indians”, compiled by Fray Ramón Pané in 1494–1498, on the express instructions of Columbus. Whatever the shortcomings of a narrative compiled by an outsider, we would be much worse off without it.     

Schmorl's nodes in a post‐medieval skeletal sample from Klostermarienberg,Austria

The prevalence and distribution pattern of Schmorl's nodes (SNs) were studied in a post‐medieval skeletal sample (n = 473) from the 16^th–18^th century cemetery of Klostermarienberg, Austria. The reasons for the prevalence and distribution pattern of SNs in this sample are discussed with regard to their aetiology. SNs were correlated with age and sex as well as with degenerative spinal joint disease such as vertebral osteophytosis (VO) and apophyseal osteoarthritis (OA). SNs were most commonly found in the lower thoracic region, in agreement with other studies. Males were more affected than females by SNs, especially in the lower thoracic region. SNs show a completely different distribution pattern to VO and OA. Additionally, there was no relationship found between SNs and ageing. Observed differences in the prevalence of SNs in the vertebral column and between the sexes suggest that mechanical factors may be responsible. Copyright © 2008 John Wiley & Sons, Ltd.     

CONSTRUCTING CARIBBEAN CHRONOLOGIES: COMPARATIVE RADIOCARBON DATING OF SHELL AND WOOD ARTEFACTS FROM PRE‐COLUMBIAN SITES IN CUBA

The lack of robust chronological frameworks for pre‐Columbian archaeology in the Caribbean limits the interpretive potential of ongoing studies of inter‐site and inter‐island interaction. This paper reviews the dating of 28 wood and shell artefacts from sites in northern Cuba in an attempt to date pre‐Columbian activity in the region and develop dating methodologies for the study of pre‐Columbian interaction in the Caribbean. This research compares dates from wood and shell artefacts from the waterlogged site of Los Buchillones in north‐central Cuba with dates from shell artefacts from sites on eight islands in the Sabana–Camaguey archipelago in the Bahama Channel. In addition to providing a chronological framework based on absolute dates for pre‐Columbian activity in northern Cuba, this paper also considers the methodological issues of using shell for dating pre‐Columbian activity in the Caribbean.     

Analysis of ante mortem trauma in three modern skeletal populations

When archaeological skeletons are assessed, the prevalence (and patterns of bone involvement) of trauma is important. The number and pattern of fractures can be used to gain insight into the occurrence of interpersonal violence, workload and living conditions. However, the question remains as to how these results should be interpreted—such as what constitutes high or low levels of trauma? The aim of this study was to investigate the occurrence of trauma in a population of modern Greeks living in Crete, as well as South African (SA) whites and blacks in the Pretoria Bone and Raymond Dart collections. The sample comprised mostly of older individuals (n = 90–100 within a sex‐population group). Each skeleton was studied for healed trauma. For the vertebrae, only spondylolysis was assessed. In the Greek sample, it was found that 42% of the males and 46% of females had at least one fracture, with corresponding figures of 63 and 44% for SA whites and 83 and 69% for SA blacks. Radius, rib and femur fractures were most common in Greeks, with skull, radius and ribs most common in SA whites and skull, ulna and ribs in SA blacks. These prevalences of trauma are high, but the composition of the samples (mostly of lower socio‐economic origin) should be kept in mind. It may also be questioned whether these individuals reflect the society as a whole. It seems that the fractures in Greeks are mostly related to old age due to falls and accidents (radius and hip fractures), while the SA black sample reflects high prevalences of interpersonal violence (such as cranial vault and ulna fractures). The SA white sample follows a comparatively moderate pattern of trauma. These comparative figures may be useful when assessing trauma in other skeletal populations.

GEOARCHAEOLOGICAL EVIDENCE FROM DESERT LOESS IN THE NAZCA–PALPA REGION,SOUTHERN PERU: PALAEOENVIRONMENTAL CHANGES AND THEIR IMPACT ON PRE‐COLUMBIAN CULTURES*

The paper presents proxies from an interdisciplinary geoarchaeological working group. Sediment analyses and geomorphological studies, radiocarbon ages of snail shells and luminescence dating of loess allow a preliminary chronology of the environmental evolution of the eastern Atacama desert, Nazca–Palpa region (southern Peru). Until now, typical desert loess was unknown from the arid western flank of the Andes (southern Peru). The loess points to periods of more humid conditions with open grasslands at the eastern Atacama desert margin in the early and middle Holocene. In the footzone of the Andes, aridification set in before the Paracas Culture (c. 800–200 bc ) evolved, but the Cordillera Occidental remained semi‐arid. A second push of increasing aridity started at the latest in the Middle Nazca Period (after ad 250). During this time, the Nazca settlement centres moved upstream through the river oasis, following the eastward‐shifting desert margin. It is possible that culminating aridity after ad 600 caused the collapse of the Nazca civilization. During the Late Intermediate Period (ad 1000–1400), more humid conditions favoured the massive reoccupation of the eastern Atacama up to a distance of about 40 km from the Pacific coast. Since the 14th and 15th centuries, the Palpa region has again been part of the hyper‐arid Atacama. The study shows that in the Nazca–Ica region, the deep cultural changes of Pre‐Columbian civilizations were not caused by catastrophic run‐off of El Niño events, but by a shifting eastern desert margin due to the changing monsoonal influence.     

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).     

Spinal pathological findings in ancient Egyptians of the Greco‐Roman period living in Bahriyah Oasis

The spine can provide a large amount of information about an individual's physical condition and possible lifestyle through palaeopathological investigations. The aim of this research was to study spinal diseases among Greco‐Roman ancient Egyptians from Bahriyah Oasis, and to compare them with those from Giza of the Old Kingdom. The material used in the study included 809 single vertebrae and 77 adult sacra of ancient Egyptians from the Greco‐Roman period (332–30 BC) that were excavated from Bahriyah Oasis. The spinal elements were examined for pathological conditions, degenerative diseases, trauma, congenital abnormalities, infectious diseases and neoplasms. The most common lesions of the spine were those due to degenerative processes. The articular facets were more affected than the vertebral bodies. Compression fractures of the bodies, mostly due to osteoporosis, were found in 1.44% and 5.07% of thoracic and lumbar vertebrae respectively. The percentage of spina bifida occulta among ancient Egyptians from Bahriyah Oasis was 62.33%, while among those from Giza was only 3.33%. Few cases of lumbar spondylolysis and one case of DISH were recorded. No cases of infectious or neoplastic diseases were found. Copyright © 2008 John Wiley & Sons, Ltd.     

Fatal Injuries in a pre‐Hispanic Canary Mummy: Violence,Accident or Ritual Suicide?

Perimortem traumas have been identified in a pre‐Hispanic Canary mummy (fifth–sixth centuries cal AD). The location and nature of the fractures in the cranium, cervical vertebrae, ribs and both legs indicate a fall from a considerable height, which would have been the cause of death. Supported by forensic anthropology criteria and historical information about the population of origin, the circumstances in which the fatal injuries might have occurred are discussed. Given the pattern of the injuries, it is debated whether they were the result of an accident or a ritual suicide, as aggression is thought to be a less likely scenario.

The Relationship between the Two Types of Vertebral Degenerative Joint Disease in a Joseon Dynasty Population,Korea

The purpose of this research was to explore the relationship between degenerative joint disease (DJD) in the apophyseal joints and intervertebral joints in the vertebral column and assess which vertebral DJD is the more reliable indicator of general activity‐related stress. We hypothesized that the more reflecting vertebral DJD for general activity‐related stress would appear to show a higher correlation with Schmorl's nodes (SNs). To test this hypothesis, we examined 125 individuals from Eunpyeong Cemetery (mid‐15th to early 20th centuries) in Seoul, Korea and analyzed the frequencies of two types of vertebral DJD and their relationship with SNs. Cross‐tabulation chi‐square tests were used to evaluate the significance of the differences between frequencies of vertebral pathologies. In conclusion, results revealed that the relationship between the two kinds of vertebral DJD appeared differently depending on vertebral region, joint type and sex. The test results of association between the two types of vertebral DJD were statistically significant at the cervical and lumbar regions of males. SNs appeared independently of the pattern of vertebral DJD in nearly all joints with the exception of a correlation between DJD in the intervertebral joints and SNs of the lumbar region in females. As indicated in some studies, this study reconfirmed that the differences in the two kinds of vertebral DJD result from differences in normal vertebral morphology and anatomical function. This study contributes to the overall discussion on the relationship between vertebral DJD and physical activity by showing that the detailed recording and understanding of the two types of vertebral DJD is required before they can be used convincingly in a study on activity‐related stress.

Avulsion injuries of vertebral endplates

Bone changes resulting from avulsions involving vertebral endplates have had little, if any, systematic attention in palaeopathological literature. To gain insight into their occurrence and into their variety, two archaeological skeletal collections covering the period AD 1455–1824 were examined. Additional skeletal material was used to illustrate typical examples. A quarter of the 44 adults who had adequate numbers of vertebrae at all spinal levels showed minor to major vertebral endplate changes as a result of avulsion injuries. The male/female ratio was 7:4. The ratio of individuals with injuries contracted during their youth and during their adulthood was 3:8 (n=11). Approximately half of the affected individuals showed such changes in multiple vertebrae. In about one third of the cases, concomitant vertebral fractures, which did not involve the endplates, were recorded. Since the existing classifications of endplate changes from avulsion injuries were developed on the basis of clinical diagnoses made by means of X‐ray or by autopsy, an adapted and extended outline for palaeopathological use is proposed. A series of differential diagnoses is discussed. Although, in general, the poor preservation of archaeological spines hampers epidemiology, the diagnosis of spinal avulsion injuries offers interesting information at the individual level.

Attitudes toward War in the United States and Iran

Understanding the determinants of attitudes toward war is important for the prevention of military conflicts and the promotion of peaceful conflict resolution. To examine American and Iranian attitudes toward war, questionnaires were administered to American and Iranian college students in the United States and Iran respectively. The results of the study revealed that American students generally have more positive attitudes toward war than Iranian students. Since most Iranians in the sample experienced eight years of war with Iraq whereas Americans never had direct experience of war, it was predicted that direct experiences of military action could explain this cross-national difference. Among Iranians those who experienced the Iran–Iraq war had more negative attitudes toward war compared to Iranians who did not have such experiences. The results further demonstrated that being authoritarian, religious and male were independently related to having positive attitudes toward war in both samples.     

The sources and formation processes of brines from the Lunnan Ordovician paleokarst reservoir,Tarim Basin,northwest China

The most important petroleum exploration target in the Tarim Basin, northwest China, is the paleokarst reservoir. To understand the source and evolution of brine in this type of reservoir, a total of 37 formation‐water samples were collected from the Middle‐Lower Ordovician paleokarst reservoir in the Lunnan oilfield. The δD‐δ¹⁸O correlation and Cl/Br ratios reflect the mixture of two fluids: meteoric water and evaporated seawater. The different degree of mixture divided samples into two groups. Group 1 samples, from deep strata (5150–6667 m.b.s.l.) in the east of the field, with elevated δD (?53.5 to ?38.0‰), δ¹⁸O values (0.66–5.99‰), and lower Cl/Br ratios (336–478 for Cl/Br, except LN634‐1 and LN631‐1) were formed by evaporation of seawater plus a small contribution from meteoric water. Group 2 samples, from shallow strata (5038–6067 m.b.s.l.), in the west of the field, have contrasting features (?59.6 to ?48.5‰ for δD, ?0.47 to 2.17‰ for δ¹⁸O, and 501 to 871 for Cl/Br), which reflect a mixture of evaporated seawater with a high proportion of meteoric water. Both of the fluid types exchanged oxygen isotope with minerals. The investigation into cation composition reveals that, before entering into the current reservoir, waters suffered albitization of plagioclase; moreover, meteoric water dissolved evaporites and seawater experienced dolomitization. A mixing trend showed by strontium isotopes (0.709801–0.711628) gave further evidence for the mixture of two fluid types. Based on the correlation of geological history with our data, two infiltration models of meteoric waters can be constructed. According to the chemical and isotopic compositions of the waters, an east fluid regime (Group 1) and a west fluid regime (Group 2) have thus been defined. Better understanding of the subsurface fluid movement patterns may be helpful for the local exploration.     

CHEMICAL–MINERALOGICAL ANALYSES AND MICROSTRUCTURAL STUDIES OF PREHISTORIC POTTERY FROM RAHMATABAD,SOUTH‐WEST IRAN*

A series of prehistoric pottery samples excavated from Rahmatabad, south‐west Iran, were investigated using XRF and XRD analyses to determine their chemical and mineralogical compositions. The sample microstructures were also studied by SEM/EDX. The relative similarity of compositions, the fine, dense and homogeneous microstructures and the presence of high‐temperature phases such as diopside and mullite showed the use of high firing temperatures, in the range 950–1050°C. This, along with the homogeneity in shape, decoration and size ranges of the ware, all indicate the adoption of specialized pottery‐making techniques by the potters of Rahmatabad in the fifth to fourth millennia bc .     

Age‐Related Cortical Bone Maintenance and Loss in an Imperial Roman Population

This article explores age‐ and sex‐related patterns of cortical bone loss, assessed by radiogrammetry of the second metacarpal, from a skeletal sample excavated from the Imperial Roman port city of Velia (1st and 2nd century ad ), to contribute to our understanding of health and disease during the Imperial period. Patterns of age‐ and sex‐related bone loss and health at Velia are also compared with other historical samples and to modern clinical data. It was hypothesised that patterns of age‐ and sex‐related bone loss in this well‐represented Roman sample (n = 71) would mirror those reported in modern populations. Differences in the quantity of cortical bone between three age groups (18–29, 30–49 and 50+ years) are significant in both men and women; however, the pattern of bone loss differs between the sexes. Women show a gradual decline in bone quantity beginning in middle age, whereas men only lose bone in old age. However, there are no significant sex differences at any age group in the metacarpal cortical index. These findings suggest the hypothesis should be refuted because significant sex differences, particularly in old age, are an expected hallmark of bone loss in Western populations today. The possible biocultural and gender‐related factors that may have contributed to the observed patterns of bone maintenance and loss at Velia are discussed.

AN EVALUATION OF ANALYTICAL AND INTERPRETATIVE METHODOLOGIES FOR THE EXTRACTION AND IDENTIFICATION OF LIPIDS ASSOCIATED WITH POTTERY SHERDS FROM THE SITE OF SAGALASSOS,TURKEY*

Three lipid analysis methods were applied to extracts of archaeological potsherds from the ancient city of Sagalassos, south‐west Turkey. In the fatty acid methyl ester fraction, obtained by selective transesterification of acylglycerols, the ratio of methyl palmitate to methyl stearate was determined. Secondly, by means of gas chromatography– combustion–isotope ratio mass spectrometry (GC–C–IRMS), stable carbon isotope ratios were measured for the same methyl esters. Finally, triglyceride composition was determined via high‐performance liquid chromatography–mass spectrometry (HPLC–MS). All three methods can be used to trace the origin of animal fat. Agreement between them is reasonable, especially in recognizing ruminant adipose fat. One sample was found to be of dairy origin using both GC–C–IRMS and HPLC–MS. The advantages of the various methods are discussed. Variations in lipid composition were observed between samples from different periods and excavated in diverse areas within the city of Sagalassos.     

Roman Period fetal skeletons from the East Cemetery (Kellis 2) of Kellis,Egypt

Much can be learned about the religious ideology and mortuary patterns as well as the demographic and health profiles of a population from archaeological human fetal skeletons. Fetal skeletons are rare, however, largely due to poor preservation and recovery, misidentification, or non‐inclusion in general burial populations. We present an analysis of 82 fetal/perinatal skeletons recovered from Kellis 2, a Roman Period cemetery dated to the third and fourth centuries AD, located in the Dakhleh Oasis, Egypt. Most of the fetal remains were individually wrapped in linen and all were buried among the general cemetery population in a supine, east–west orientation with the head facing to the west. Gestational age estimates are calculated from diaphysis lengths using published regression and Bayesian methods. The overall similarity between the fetal age distributions calculated from the regression and Bayesian methods suggests that the correlation between diaphysis length and gestational age is typically strong enough to avoid the ‘regression’ problem of having the age structure of reference samples adversely affecting the age distribution of target samples. The inherent bias of the regression methods, however, is primarily reflected in the gestational age categories between 36 and 42 weeks corresponding with the expected increase in growth variation during the late third trimester. The results suggest that the fetal age distribution at Kellis 2 does not differ from the natural expected mortality distribution. Therefore, practices such as infanticide can be ruled out as having a significant effect on the observed mortality distribution. Moreover, the Kellis 2 sample is well represented in each gestational age category, suggesting that all premature stillbirths and neonatal deaths received similar burial rites. The age distribution of the Kellis 2 fetal remains suggests that emerging Christian concepts, such as the ‘soul’ and the ‘afterlife’, were being applied to everyone including fetuses of all gestational ages.
