Radiocarbon Dating of Architectural Mortar: A Case Study in the Maya Region,Quintana Roo,Mexico

Abstract

The use of radiocarbon dating to analyze mortar and charcoal inclusions within mortar or plaster is a useful way to date the construction of architecture, particularly when options for other chronometric methods are limited. In the Yalahau region of northern Quintana Roo, Mexico, members of the Yalahau Regional Human Ecology Project have faced challenges in dating buildings made of large blocks of stone in the Megalithic architectural style. The Megalithic style poses serious problems for any analysis, as excavating into structures with stones weighing several tons can be dangerous, expensive, and time consuming. Additionally, there are no associated sculptures, texts with dates, or other traditionally accessible chronological markers. These factors have resulted in a reliance on a ceramic chronology despite the uncertainty of the dating of many ceramic types in this region, as well as the questionable contextual associations between recovered ceramics and architectural construction phases. Megalithic-style structures at the ancient Maya site of El Naranjal have residual mortar with charcoal inclusions left behind during the mortar-making processes that can be extracted and dated with AMS ¹⁴C methods. Several samples of mortar and charcoal were obtained from structures 1 and 10 from exposed exterior walls and an interior vault. The resulting dates confirm the date for the construction based on ceramics excavated from the same site.     

Eros and Dionysus

Abstract

Liberty was once praiseworthy because it enabled a free choice for the good. Technology recasts the classical link between liberty and virtue by making human well-being depend on technological advance. Till recently, technology signified human mastery over nature. But now virtual reality offers itself as a substitute for nature. Unlike machines which hold us at a distance, it draws us in with images. It no longer shapes the soul indirectly through the effects of using machines, but involves the soul directly. The modern attempt to bracket the soul has brought it back virtually. The argument between fight and flight is at a standstill. Instead, the irony which many lament as a feature of postmodernity can provide a distance from the technologies which have made themselves necessary.     

Sponge Spicules in Pottery: New Data from Mali

Abstract

Until recently, the presence of sponge spicules in ancient ceramics has only been reported from South America. Current technological studies of Neolithic pottery from Sudan and Iron Age pottery from Mali provide evidence that sponge spicules are also a distinctive inclusion of some African ceramics. In this study, new data concerning the presence and quantitative variability of sponge spicules in West African Iron Age pottery from sites along the Niger River are discussed. Additionally, we discuss the potential archaeological insights offered by the study of sponge inclusions in pottery, and we consider methods for assessing whether or not these spicules were intentionally added as temper to vessels.     

Authentic Kyrgyzstan: top down politics meet bottom up heritage

Abstract

Over the past twelve years I have collaborated with Kyrgyz citizens to promote a national conversation about heritage, based on grass roots interest and sentiment. Countering polarising political rhetoric about Kyrgyz nomadism as the only authentic national heritage identity, many citizens enthusiastically present the artefacts of ancient cities alongside the balbals (stele) of ancient nomads in their community museums, eagerly participate in discussions about a complex Kyrgyz past, and have collaborated with Uzbek speakers to create a national heritage society. In this paper I will describe several community museums and other grass roots education programmes that I have been involved with in Kyrgyzstan and consider their potential for countering ethnic conflict.     

Finding a Relatively Flat Archaeological Site with Minimal Ceramics: A Case Study from Iraqi Kurdistan

ABSTRACT

We present a new technique to detect flat archaeological sites with minimal ceramics using an unmanned aerial vehicle that maps surface stone concentrations. Methods deployed include point pattern analysis of stone concentrations and a machine-learning technique using unsupervised classification of visible stone signature qualities, which are used in simple linear regressions to compare with geophysical and ceramic surface survey results of a site in Iraqi Kurdistan. There is a stronger fit (r^2?=?0.77) between surface stone concentrations and architecture identified by geophysical measurement, while surveyed ceramics show a weaker fit to defined architecture (r^2?=?0.31). Surface stone concentrations are potentially a better proxy than ceramics for determining the presence of past settlement in regions where stone was commonly used, sites are relatively flat, and ceramics are found in low concentrations. The methods advanced here can be scaled to wider areas, particularly in mountainous regions, where surface stone features are present.     

Artefacts,archaeologists and American Indians

Abstract

Archaeologists traditionally have observed the style and technology of artefacts and used this to classify archaeological assemblages, describing the repeated association of artefact groups as a ‘Culture’. We continue to place overwhelming reliance on our ability to derive meaningful information about past culture from artefacts, yet the importance these objects had for the members of the cultural group (past and present) is not adequately considered. The typological approach sidelines the creative role of the artisans, we find out a little about their economy, gain momentary glimpses of their religion, but learn almost nothing about their humanity. Archaeologists tend to focus on the physical, technological or esoteric attributes of an artefact, while indigenous populations tend to focus on the object's ritual or social importance. This is most apparent in the treatment of funerary artefacts. Until recently, many American Indian tribal groups have seen no distinction between ‘grave robbing’ and ‘archaeological excavation’ it made no difference to them whether the dead were disturbed by looters or by qualified archaeologists. By involving indigenous populations in the design, practice and dissemination of archaeological research, we can add humanity to our study of the human past, and take a step toward a truly worldwide archaeology.     

Sculptures in captivity and monkeys on megaliths: Observations in zoo archaeology

Abstract

This paper reconsiders some aspects of displays at archaeological open-air museums and heritage sites by looking in some detail at how wild animals are presented in zoological gardens. Topics discussed include the historic and current functions of collecting ancient artefacts, the various appeals of different artefacts and displays, trends in attracting visitors, the significance of systematics and typology, narratives reflected in the overall exhibition design, and the role of displaying artefacts in a specific ‘culral’ context. I argue that we should learn from zoos by placing a stronger emphasis on sensory experiences and visitor satisfaction in order to convey the ‘magic’ of the past.     

DETECTING FORGERIES AMONG ANCIENT GOLD OBJECTS USING THE U,Th–4He DATING METHOD*

Forgeries of ancient gold objects are prevalent in almost every collection and some public exhibitions in the past have been exposed as containing forgeries to an embarrassing extent. This situation comes from the fact that it is sometimes impossible to unequivocally recognize forgeries based on their patina or manufacturing and decoration characteristics. We demonstrate that for 13 ancient gold objects the time of their last melting process can be estimated using the U,Th–⁴He dating technique. The extremely small quantities of radiogenic ⁴He found, due to the young age and small sample size, require the use of a specially designed ultrasensitive mass spectrometer. We show that the proposed method is a powerful, and the only, quantitative tool in archaeometry for discriminating between fake and genuine ancient gold objects.     

基于XRF与TL技术相结合的古陶瓷产地判别研究

古陶瓷产地判别一直是古陶瓷研究工作的一个重点。为了拓展产地判别的科技研究方法,本研究针对南北方4个不同窑口(越窑、建窑、耀州窑、定窑)的古陶瓷样品,首次结合采用X射线荧光光谱分析(XRF)和热释光(TL)测试分析技术相互印证,测定4个窑口样品的胎釉元素组成和热释光特性,并建立相对应的数据库,相互印证判别古陶瓷样品的产地。数据库的统计分析表明:同一窑口的古陶瓷不仅在主量与微量元素化学组成具有一定的地域特征,其热释光的测量灵敏度也存在地域特征性;不同窑口的古陶瓷可以通过元素组成归类和热释光特性的不同加以区分,结合采用XRF与TL测试分析两种技术可以更准确地对古陶瓷产地进行分析判别。     

Prehistoric Mink (Mustela vison) Trapping on the Northwest Coast

Abstract

Excavations and survey since 1970 have produced data on many aspects of human occupation in the Basin of Mexico between 1200 B.C. and 500 B.C. (un calibrated radiocarbon dates). We attempt here to summarize our current understanding of the communities of that period in the Basin, with respect to chronology, stylistic affinities of their material remains, subsistence patterns, craft production, trade relationships, socio-political aspects, and the possible religious beliefs of their inhabitants. We urge in conclusion that even-handed attention be provided to both the historical and the processual aspects of the evidence in the interest of a more complete understanding of the past in our region.     

Stable nitrogen isotopic examination of Norse sites in the Western settlement of Greenland

To continue to explore the impact of past human activity on the stable nitrogen isotope ratios of modern vegetation, we have measured the δ¹⁵N values of plants now growing on several ancient farmsteads in the Western Settlement of Norse Greenland. Although this new test area is some 400 km north and in a different ecoregion from the previous study area, the same isotopic effect was observed. A clear isotopic signature was found on the ancient farms which could be directly correlated to past activity areas; in particular, the infields. Further, the magnitude of the δ¹⁵N values was found to be similar between study areas, indicating the same interpretative framework can be applied in widely separate geographic regions. A first test of different plant species showed that although the magnitude differed greatly the same basic information was found for functionally different plants. These observations provide additional information to aid in future archaeological application of this newly observed phenomenon.     

Preserving a Monument: The Example of the Parthenon

Abstract

The preservation of architectural relics of the past developed as a science mainly in the last century. The more a ruin is preserved, the more information it may provide about the past. Structural interventions on relics aim to improve their state of preservation for the future, as well as to render their shape more complete, for the overall purpose of safeguarding their historical information. Over the course of past decades interventions have undergone many changes with respect to methodology, materials, and scope. Intervention in the name of preservation can be interpreted in various ways and questions concerning the goals and nature of modern interventions have become particularly relevant. The current Parthenon Restoration Project, which differs in basic aspects from its predecessors, follows international guidelines for interventions, but remains distinctive for its extent as well as its methods of execution. This paper discusses the theoretical approach underlying the intervention and practical aspects of its methodology.     

Refining oxygen isotope analysis in the Nasca region of Peru: An investigation of water sources and archaeological samples

The development of complex societies, irrigation agriculture and sociopolitical transitions are of interest to researchers working in the Nasca region on the south coast of Peru. Occupied for thousands of years, many questions regarding the circumstances of these changes in the area are being investigated. Oxygen isotope analysis provides a method for exploring residential mobility of past peoples during these transitions. This study presents new δ¹⁸O data from water sources that would have been used by the ancient inhabitants, providing important information regarding the oxygen isotope variability in the region and the necessary baseline data for migration studies in this region. Our results suggest that the isotopic composition of water sources in the Nasca region is not highly variable. In addition, archaeological human tooth enamel samples from the sites of La Tiza and Pajonal Alto are analysed. The δ¹⁸O_c results of the human enamel samples confirm the local nature of the burial population, as suggested by previous strontium isotope analysis (⁸⁷Sr/⁸⁶Sr).

The Role of Functional Efficiency in the Decline of North America’s Copper Culture (8000–3000 BP): an Experimental,Ecological, and Evolutionary Approach

The copper-using cultures of North America’s Archaic Period (10,000–3000 BP) have long been an archaeological enigma. For millennia, Middle and Late Archaic hunter-gatherers (8000–3000 BP) around the Upper Great Lakes region made utilitarian implements out of copper, only for these items to decline in prominence and frequency as populations grew and social complexity increased during the Archaic to Woodland Transition. From a cultural evolutionary perspective, the trajectory of North America’s copper usage presents a conundrum, as it is generally assumed that “superior” tools, i.e., metals, will replace inferior ones, i.e., stone. For well over a century, scholars have pondered the reason for the demise of copper technology that was once a wide-spread phenomenon. To address this question, an extensive archaeological experimental program was conducted which compared replica copper tools (spear points, knife blades, and awls) to analogous ones made of stone or bone to assess whether relative functional efficiency contributed to the decline of utilitarian copper implements. Here, the results of this three-part research program are presented in concert with population dynamics and ecological change to paint a broader picture of the complex interrelationships between the social, ecological, and technological spheres of past human behaviors. The synthesis of these approaches reveals that functional explanations—derived from experimental archaeology placed in an evolutionary framework—can shed much light on the trajectory of metal use in the North American Great Lakes.

     

State Ceremonial,Court Culture and Political Power in Early Modern Denmark, 1536-1746

In early modern Europe the court of a prince was many things: the household of a prince, a point of contact between the ruler and the elites, a cultural trendsetter, a focal point of patronage and an important institution of regional and international politics. In short, the court had many functions. In this article the focus is on the main lines of development in the court culture of early modern Denmark, from the Reformation (1536) until early Absolutism. Certain structural changes are highlighted and an attempt is made to explain them in political terms. As a prelude, I offer some theoretical reflections on the meaning of court culture in general and ceremonial culture in particular. Let me say from the outset that I have found my inspiration mainly in German and American historical scholarship, which for the past twenty years or so has witnessed a continuous and fruitful debate on the early modern court.     

The Evolution of Innovation Networks and Spin-off Entrepreneurship: The Case of RAD

Abstract

We conducted an in-depth analysis of an Israeli startup, RAD Bynet, founded in 1981, that has intentionally, through the vision of its founder, given rise to 129 other startups employing some 15,000 workers, and created a unique “cloud”. Through a survey of the existing firms, we sought to explore the nature of this ecosystem and to quantify the relationships that exist between the mother company and the enterprises that emerge from it. Our main findings were: (a) social and technological proximity encourages the tendency of the companies to maintain business relationships that probably contribute to knowledge exchange, while technological diversity drives innovation and startup formation; and (b) firms will choose to cooperate on the basis of a shared past and personal proximity relations, as well as technological proximity at a certain level; “viral clouds” of startups like the one we studied can thus intentionally be designed and developed.     

More Evidence for an Advanced Prehistoric Iron Technology in Africa

Abstract

Ethnographic and technological observations of iron smelting among the Raya people of NW Tanzania during 1976 and 1979 have contributed important new evidence for a technologically advanced culture in East-Central Africa. The ethnoarchaeology of Haya iron working shows that the Raya practiced an iron-smelting technology that employed preheating of the air blast—a highly efficient technique—and formed a massive steel altogether different from that known in the European tradition of iron production.

Excavations in 1977 at the KM2 site near Kemondo Bay west of Lake Victoria in Kagera Region, Tanzania, provided abundant evidence for an ancient technology, dating to the first six centuries A.C., that shared many similarities to the living iron-smelting technology. Excavations during 1978–1979 at the KM3 site, also located near Kemondo Bay, yielded physical evidence for the antiquity of the preheated process and provided definitive proof for a technology similar to the process in historical times. These discoveries affirm that one of the most advanced technologies in the ancient world developed in Africa independent of European influence.     

Roadlessness and the Person: Modes of Travel in the Reindeer Herding Part of the Kola Peninsula

Five wooden spoons dated to the Sub-Neolithic and Bronze Age are known from Finland. Four of them have an animal head carved onto their handles. The decoration has usually been seen as a sign of the spoons' totemistic and ceremonial use. Three of the spoons are stray finds, one comes from a possible cult site and one from a dwelling site. Two spoons are made of Siberian pine, which makes them objects of trade exchange; the westernmost natural occurrence of the raw material was in the Ural Mountains. Previous interpretations of the spoons have inconsistencies and rigid categorizations, which are reconsidered here from the perspective of cultural biographies of things. The functional aspects, ceremonial use and find contexts of the spoons are re-examined along with their connections to totemism, shamanism and ancient trade.     

Saul and Cultural Memory

ABSTRACT

In recent years a number of biblical scholars have shown that the Hebrew Bible contains both the collective memory and amnesia of ancient Israel. The differences between the portrayals of Saul in the books of Samuel and 1 Chronicles have long been explained in terms of redaction history, inner-biblical exegesis and other intertextual reading strategies. Using the insights from the fields of sociology and psychology cultural memory theory suggests that it was the dynamics of structural amnesia that made it necessary to suppress the memories of Saul that were not useful to the reconstruction of the past, and that the new “master narrative” in the Book of Chronicles may be seen as a post-trauma solution to the Israelites’ painful retrieval of memories of guilt and trauma.     

The Gallo-Roman sanctuary at Grand,France: II The protection and development of the amphitheatre

Abstract

The amphitheatre at the Gallo-Roman sanctuary in Grand (France, Département des Vosges) is an outstanding example given its non-Mediterranean location. The clearing of rubble from its remains, between 1963 and 1977, led to the masonry deteriorating rapidly due to weathering. The installation over part of the monument of a protective covering, incorporating tiers of seating, constitutes a technological first, as it is made of glued-laminated softwood constructed to demanding specifications. The covering serves to protect and reconstruct part of the amphitheatre, in which it is now intended to hold cultural events. This type of development requires careful planning regarding practical arrangements, marketing strategy and artistic issues.
