Geoarchaeological evidence for ritual closure of a kiva at Fourmile Ruin,Arizona

Geoarchaeological analyses, including soil micromorphology and chemistry, were used to characterize the deposition history of a fourteenth-century Pueblo ceremonial structure (or kiva) at Fourmile Ruin, east-central Arizona. These subterranean structures were often ritually “closed” by Pueblo societies through the burning of roofs and the deposition of special objects. These conspicuous markers are absent in the Fourmile Ruin kiva, but the composition of constituent materials and sedimentation processes nonetheless signal complex, highly-orchestrated closure activities. The study demonstrates the efficacy of geoarchaeological analyses of stratified deposits for modeling the subtle behaviors associated with the ritual closure and abandonment of sacred places.     

Pit Structure Abandonment in the Four Corners Region of the American Southwest: Late Basketmaker III and Pueblo I Periods

Abstract

Anasazi pit structures dating to the Basketmaker III and Pueblo I periods (ca. A.C. 500 to 900) in the Four Corners region of the American Southwest experienced a variety of different processes at abandonment, ranging from dismantling the superstructure to intentional burning. Data from 88 pit structures are used to examine the relationship between these processes and the causes of pit structure abandonment. Results suggest that burning was not usually the result of catastrophic events, such as accident or warfare, but may be part of ritual activities or even a response to insect infestation. The incidence of burning does not seem to increase over time as a result of the postulated transition of pit structures from domestic to ceremonial uses. Dismantled and trash-filled pit structures suggest that new dwellings were often constructed near abandoned ones, perhaps because the old structure was deteriorating. A few pit structures with human bodies on the floor at the time of abandonment may signal the desertion of the entire settlement.     

Ancestral pueblo population aggregation and abandonment in the North American Southwest

After over a century of archaeological research in the American Southwest, questions focusing on population aggregation and abandonment continue to preoccupy much of Pueblo archaeology. This article presents a historical overview of the present range of explanatory approaches to these two processes, with a primary focus on population aggregation in those regions occupied by historic and prehistoric Pueblo peoples. We stress the necessarily complementary nature of most of these explanations of residential abandonment and aggregation. Case studies from the northern Southwest illustrate the continuous nature of these processes across time and space. We suggest that additional explanatory potential will be gained by the use of well-defined theoretical units to frame our current approaches. We extend the use of the local community concept as a theoretical unit of organization that, along with explicit archaeological correlates, should help advance our research into population aggregation and abandonment in this and other regions of the world.     

Cacao consumption during the 8th century at Alkali Ridge,southeastern Utah

Theobroma cacao was detected in the ceramic assemblage at the 8th century Site 13, Alkali Ridge, southeastern Utah. The presence of this Mesoamerican beverage during the Pueblo I period is the earliest reported use of cacao in the northern American Southwest, coming centuries earlier than the recently documented Pueblo II consumption of cacao in cylinder jars, sharp-shouldered pitchers and shallow bowls at Pueblo Bonito, Chaco Canyon. Analogous to the situation at Chaco, cacao was found at Site 13 in a new vessel form decorated with a distinctive design system that contrasted markedly with designs and vessel forms in the local black-on-white ceramic assemblage. We postulate that Abajo R/O at Site 13 represents a ceramic tradition brought by one of the many groups moving into the northern Southwest. The detection of cacao in their ceramic vessels represents new evidence for the migration model that for centuries brought people with Mesoamerican beliefs, ritual practices and a new subsistence lifeway into the American Southwest.     

The role of a Chaco-Era great house in the Southern Cibola Region of West-Central New Mexico: The Largo Gap great house community

Largo Gap is one of several late Pueblo II (a.d. 1050–1130) Chaco-style great houses located in the southern Cibola region of west-central New Mexico. This region is at the interface of two Southwestern cultural areas: Mogollon and Pueblo. We report results of survey and excavation research at the Largo Gap great house and associated community to explore the role great houses in this region served for local populations, as well as their articulation with other great houses across the “Chaco Sphere.” The results identify Largo Gap as an architecturally “Chacoan” structure and that use of this structure incorporated both Mogollon and Puebloan material culture. The use of ceramics from both ancestral culture groups indicates that the local community was multi-ethnic, and suggests a socially-integrative role for the great house within this region.     

Territorial Behaviour and Communication in a Ritual Landscape

Landscape research in the last decade, in human geography as well as in anthropology and archaeology, has often been polarized, either according to traditional geographical methods or following the principles of a new, symbolically orientated discipline. This cross–disciplinary study in prehistoric Östergötland, Sweden, demonstrates the importance of using methods and approaches from both orientations in order to gain reasonable comprehension of landscape history and territorial structure. Funeral monuments as cognitive nodes in a prehistoric cultural landscape are demonstrated as to contain significant elements of astronomy, not unlike what has been discussed for native and prehistoric American cultures, e.g. Ancestral Pueblo. A locational analysis with measurements of distances and directions was essential in approaching this structure. A nearest neighbour method was used as a starting–point for a territorial discussion, indicating that the North European hundreds division could have its roots in Bronze Age (1700–500 BC) tribal territories, linked to barrows geographically interrelated in cardinal alignments. In the European Bronze Age faith and science, the religious and the profane, were integrated within the framework of a solar cult, probably closely connected with astronomy in a ritual landscape, organized according to cosmological ideas, associated with power and territoriality. Cosmographic expression of a similar kind was apparently used even earlier, as gallery–graves (stone cists) from the Late Neolithic (2300–1700 BC) in Östergötland are also geographically interrelated in cardinal alignments.     

The Virgin Anasazi,far western Puebloans

In the American Southwest, the Virgin Anasazi region included the western part of the Colorado Plateaus and the river valleys of the adjoining Mojave Desert in Utah, Nevada, and Arizona. This occupation spanned the Puebloan periods from Basketmaker II to Early Pueblo III, roughly A.D. 1 to A.D. 1200. Virgin Anasazi subsistence combined cultivation with hunting and gathering. Current research is unveiling a prehistoric society with flexible food procurement strategies and group organization. They underwent a version of the pit house-to-pueblo transition familiar from the Kayenta and northern San Juan areas. Both intra- and interregional exchange seems to have peaked in Late Pueblo II times and then fallen off prior to the end of their culture history. Face-to-face communities remained small, even into the late 1100s, when other Anasazi areas saw the beginnings of aggregation. Their fate, early in the widespread abandonment of the northern Southwest, remains to be understood.     

Where are the roofs? A geo-ethnoarchaeological study of mud brick structures and their collapse processes,focusing on the identification of roofs

Unlike floors that have been given a lot of attention in archaeological research, the study of roofs is long neglected. Here, we present a study of modern abandoned and burnt mud brick structures, conducted in southern Israel and northern Greece. Using macroscopic observations and interviews together with micromorphology, mineralogical, phytolith, and phosphate analyses, we show that roofs should be sought in close proximity to floors. We show that roofs practically seal activity remains on floors; thus, the importance of identifying roofs in the archaeological record lies mainly with the ability to estimate the integrity of floors and floor assemblages. While human behavior and maintenance practices are major factors in the deposition of primary activity remains on floors, the timing of roof collapse determines how well activity remains will be preserved. In addition, we show that the roof plays a major role in the degradation process of mud structures as wall degradation is enhanced after the collapse of the roof resulting in accumulation of mud brick degradation material on top of the collapsed roof. As most roofs in antiquity seem to have been composed of degradable vegetal materials, we found that not only they leave little evidence for their presence, but they also mix with vegetal activity remains. We therefore use the accumulation of mud brick debris as an indicator for the location of degraded roofs. Using microstratigraphy for the identification of both floors and roofs is significant in order to locate activity remains in the archaeological sedimentary sequence and to evaluate their state of preservation.     

Social Change and Hunting during the Pueblo III to Pueblo IV Transition,East-Central Arizona

Abstract

The transition from the Pueblo III to the Pueblo IV period (A.D. 1100–1400) in the American Southwest involved marked population aggregation. Diverse economic, political, and religious factors must have played a role in the integration of these populations. Bailey Ruin, Bryant Ranch, and Pottery Hill, three sites in the Silver Creek drainage of east-central Arizona, show increased hunting of large mammals during this transition. This trend has elsewhere been attributed to hunting specialization due to local resource depletion and perhaps the need for a seasonal supplement to maize-based diets, but these factors do not adequately explain the data here. In fact, the regional reliance on rabbit protein suggests that hunting larger game was not necessary to meet dietary needs in an environment where small game is a reliable food source and artiodactyls are rare. Rather, the increased proportion of large mammals in the Silver Creek area faunal assemblages seems to reflect larger issues of social reorganization. Rituals aimed at community integration and individual attempts to gain authority and prestige were focused on communal hunts, feasts, and the production of ritual paraphernalia through large-game hunting.     

The Dramatic Abandonment of a Late-Antique Settlement in the South Caucasus: The First Archaeological Findings from Qaratəpə, Bərdə Rayon,Azerbaijan

This paper presents the first results of a new project investigating the provincial structure of the eastern Caucasus region in the late Antique and early Islamic periods. Excavations at the newly discovered rural archaeological site of Qarat?p? have so far revealed two phases of use: a burial ground dating to the 12th century a.d. and an unusually large earthen structure burnt in a catastrophic fire. Owing to the rapid abandonment of this building, whole ceramic and glass vessels were recovered from the fill of one of the rooms. The presence of charred seeds and roof timbers allowed for the acquisition of radiocarbon dates for the construction and abandonment of the building, placing the latter at the end of the 6th century a.d. These findings reveal crucial clues as to the transformation of the rural zone prior to the expansion of Islam, and a unique material assemblage dating from this period.     

Rock Art and Ritual: An Archaeological Analysis of Rock Art in Arid Central Australia

Rock art researchers throughout the world have explicitly or implicitly invoked ritual as an activity associated with the production of rock art but the articulation between the structure and composition of rock art assemblages and ritual behaviour remains poorly understood. Anthropologist, Roy Rappaport (1999) argued that all ritual, whatever the content or focus, has a universal structure. We review this proposition in the context of ritual studies and propose a method aimed at assessing the potential for identifying ritual structure in rock art assemblages. We discuss an archaeological analysis undertaken on the rock art assemblages in arid Central Australia, which aimed at distinguishing such a ritual structure among engraved assemblages, likely to have a Pleistocene origin, as well as more recent painted, stencilled and drawn assemblages. This analysis, despite its limitations, provides the foundation for developing a model, which will enhance the understanding of the relationship between the production of rock art and ritual.     

Recent Researches Among The Pyramids

Recent consideration of the date of construction of the hall at Tamworth Castle puts the building into a medieval context. It is suggested that the structure was raised in the second quarter of the fifteenth century or earlier. With a span of over eight metres (27 feet) its impressive tie-beam and double collar roof trusses represent the full structural development of the post and truss tradition and its place in that tradition is discussed. This significant late medieval timber frame has not stirred much interest since J. C. Buckler drew part of a roof truss (B.M., M.S. 36436, p.38620) and little documentary evidence has come to light which might establish close dating of the structure. A short account of the associated domestic buildings inside the shell keep reflects the general trend from first floor to ground floor hall and the eventual abandonment of the latter as the centre of the household.     

SEISMIC DESIGN AND ANALYSIS OF A KNEE BRACED FRAME BUILDING

A five-storey steel frame incorporating dissipative knee elements is designed using the Eurocode 8 pushover analysis method. The non-linear analysis makes use of a novel knee element model capable of accurately simulating the bending and shear behaviour observed in full-scale tests. The performance of the structure is assessed using non-linear time-history analysis. This shows that the knee elements can be designed to yield under small earthquakes or early in a strong one (maximising their energy dissipation) while still being able to withstand a large event without collapse. Knee elements thus have the potential to give excellent seismic performance in steel framed structures. The time history analysis results are compared to those obtained with the three different pushover analysis methods (Eurocode 8, FEMA 356 and ATC 40). The FEMA 356 method, which includes a more accurate representation of the structure's significant post-yield stiffness, gave the closest agreement with the time history analyses, while the Eurocode 8 method gave rather conservative results and the ATC 40 method appears non-conservative for this type of structure.     

Pueblo Settlement,Architecture, and Social Change in the Pueblo Revolt Era,A.D. 1680 to 1696

Abstract

In A.D. 1680, the Pueblo Indians of the American Southwest united in a revolt that drove Spanish colonists out of Pueblo lands for more than a decade. Dramatic changes in the architecture, spatial organization, and settlement patterns of Pueblo villages occurred during this era as Pueblo leaders sought to revive traditional beliefs and practices. Semiotic and space syntax analyses of 10 Pueblo Revolt-era (1680–1696) villages reveal evidence for an ideology of cultural revitalization, as well as changing patterns of leadership and social interaction. Villages built early in this period exhibit planned communal construction and evidence of strong centralized leadership that resulted in highly structured social interaction. In contrast, later villages are characterized by less centralized leadership and a dispersed layout that facilitated the informal interactions necessary for communal integration in a time of increased migration. The social changes reflected in and shaped by Revolt-era architecture were crucial in the formation of modern Pueblo culture, influencing village alliances and spatial organization down to the present day.     

Wood deterioration in Chacoan great houses of the southwestern United States

Abstract

‘Great houses’ built by the Ancestral Puebloans (Anasazi) (900–1200AD) still contain thousands of pieces of wood used as beams, secondary roof supports and lintels. The wood is an integral part of the surviving Chacoan architecture and has served as a valuable resource for determining the exact age of the structures and for obtaining information about raw material production, procurement and harvesting methods. An assessment of wood deterioration at the great houses in Aztec Ruins National Monument and Pueblo Bonito, Pueblo del Arroyo and Chetro Ked located in Chaco Culture National Historic Park in New Mexico have revealed that both microbial and non-biological deterioration was taking place. The major type of decay found throughout the structures was caused by soft-rot fungi. Cavity formation in secondary walls of conifer woods and an erosion of cell walls in aspen woods was prevalent. A brown-rot type of wood degradation was also found, primarily associated with areas of subterranean termite damage. Another form of deterioration present in some of the woods was a chemical de fibration of wood. This corrosive attack, caused by high concentrations of salts, destroyed the middle lamella between cells, resulting in a stringy mass of loosely attached fibres. Reburial of great house structures as an effective conservation strategy will require an environment that is not conducive to decay, since active wood-destroying fungi are present in the prehistoric woods. If moisture and other conditions suitable for decay exist, the wood will be destroyed and this important historical resource lost.     

Blood-brothers: a ritual of friendship and the construction of the imagined barbarian in the middle ages

This article analyses the history of blood-covenants in the middle ages. Appearing in various historiographical and literary texts from antiquity onwards, these covenants have hitherto mostly been interpreted by modern authors as a typical feature of pre-modern or even ‘primitive’ societies. A closer inquiry into the context of the existing source-material reveals, however, that this motif can be characterised as a part of discriminatory narrative strategies which aim at the exclusion of foreign and non-Christian cultures. The analysis of the medieval texts, which were mainly produced from the twelfth century onwards, clearly shows a tendency to attribute this ritual of blood-brotherhood either to representatives of the so-called ‘Saracens’ or allegedly heterodox cultures, like the Byzantines or the Irish, which populated the margins of the Latin west. Not only does this topical use of the motif invalidate part of the texts' factual source value, but it also proved misleading for the interpretation of pre-modern societies by modern historians. While an older tradition of classical political history mainly tended to note the ritual as a cultural curiosity, more recent studies of ritual structures are in danger of misrepresenting the cultures they focus on.     

Identifying pre-Hispanic water storages in agricultural areas of south-central Andes through diatom evidence

In the Andes, there are several pre-Hispanic irrigation networks with structures destined for water storage. However, it has not been widely discussed in archaeological research. This is probably due to their being difficult to identify. The aim of this study is to explore the use of diatom assemblage analysis as a methodological tool suitable to help in the identification and characterization of these ancient hydraulic structures. We analyzed two archaeological structures interpreted as water reservoirs from north-western Argentina (EH1 in Antofagasta de la Sierra and U-88R1 in Yocavil) and compared them to current reservoirs. The diatom species composition and the changes in the dominant ecological groups in the studied structures highlight different periods of hydraulic behavior. EH1 contained and stored water, but there were periods of time in which there was a lack of use or abandonment of the structure. However, the U88-R1 structure does not have diatom evidence of containing standing water for a prolonged time but presence of wet soils. Thus, the structure could have been used for other water management strategies. The results show that diatom analysis is a methodological tool with a high potential to study ancestral hydrotechnologies.     

The Depositional Contexts of the Ships from Thonis‐Heracleion,Egypt

Over 70 ancient vessels have been discovered by the Institut Européen d'Archéologie Sous‐Marine in the port‐city of Thonis‐Heracleion, Egypt. These were deposited both individually and in groups from the 8th to the 2nd century BC. This paper investigates the contexts of these vessels to suggest that a variety of explanations—shipwrecking, ritual deposition, abandonment, and structural reuse—account for their deposition. It also seeks to place these events within the changing landscape of Thonis‐Heracleion to understand the agency behind many of the decisions about what to do with old ships and boats at the end of their use‐life.     

“…being weary,they had rebelled”: Pueblo subsistence and labor under Spanish colonialism

Native American responses to Spanish colonialism are explored through an analysis of multiple lines of evidence concerning subsistence practices, diet, and health in the Salinas Pueblo area of central New Mexico. Zooarchaeological and paleoethnobotanical data from three Pueblo villages that experienced different degrees of Spanish missionization are the focus of this study. In addition, human osteological data from one village provide important information on activity patterns and health. These data are used to document the kinds of changes that occurred in Pueblo labor patterns, food consumption, and health from the pre-colonial to colonial periods. Synthetic analyses document the development of some degree of inter-village specialization in large game hunting, hide processing, and corn farming, presumably in response to Spanish tribute levies in corn and antelope hides, and demands on Pueblo labor in other arenas. There also appears to be a degree of divergence in women’s and men’s lives in the colonial period. These southwestern data are then compared with similar information from the southeastern US to identify patterns of similarity and difference in Native American experiences of and strategies for dealing with Spanish colonization.     

High precision isotopic analyses of lead ores from New Mexico by MC-ICP-MS: implications for tracing the production and exchange of Pueblo IV glaze-decorated pottery

Between ca. 1275 and 1700 CE, Pueblo groups in the northern Southwest United States produced and exchanged ceramic bowls decorated with lead-based glaze paints. Previous studies of these glaze-decorated bowls have used lead isotopic analysis by ICP-MS to identify the sources of lead used by Pueblo potters, and investigate how social or economic factors may have influenced resource use among different Pueblo communities (e.g. 13 and 14; Huntley et al., 2007; Huntley, 2008). However, interpretations of much of this isotopic data have remained provisional because of overlap among the isotopic ratios of potential sources and because the isotopic composition of many glaze paints do not clearly match any known source. Here, we use multi-collector ICP-MS to re-measure the lead isotopic composition of 48 samples of lead sulfide (galena) and lead carbonate (cerussite) from sources in New Mexico that were potentially utilized by Pueblo potters, including mines within the Cerrillos Hills, Magdalena, Hansonburg, and Joyita Hills mining districts. These results define the isotopic composition of lead ores from these districts with greater precision and accuracy than achieved in previous studies and better distinguish among these mining districts in lead isotope space. Most significantly, we find that galena mineralization within the Cerrillos Hills only has a modest degree of isotopic variation, with ²⁰⁶Pb/²⁰⁴Pb ratios from 18.508 to 18.753, ²⁰⁷Pb/²⁰⁴Pb ratios from 15.580 to 15.607, and ²⁰⁸Pb/²⁰⁴Pb ratios from 38.388 to 38.560. These ranges are far narrower than previously reported, and should supersede previously published values for this district. In total, we conclude that isotopic measurements of both ores and glaze paints made by MC-ICP-MS will provide new information about the provenance of lead in glaze paints and allow for more detailed interpretations about resource procurement and exchange in the Pueblo world.
