Three Methods for Detecting Past Groupings: Cultural Space and Group Identity

Grouping techniques employ similarities within data to create new entities, which lend themselves to the interpretation process. This article presents three different grouping approaches, each originally developed independently, and applied to a common dataset of archaeological finds. The aim is not to search for the right approach or results, in a competing way, but rather to present the methods as complementary. It is also our intention to stress that a tight connection between theory and statistical modelling is indispensable. Indeed, the use of a particular methodology must be supported by an adapted theory; similarly, a theory without a proper methodological realisation will often not have any actual utility. The integration of theory and method is exemplified in the three case methods. The first method uses metal objects as cultural indicators. The study area is divided into a set of identical geographical units, characterized according to the type and proportions of indicators and grouped using hierarchical clustering. The second approach deals with cultures as standardisations between individuals, using ‘Typenspektrum’ as significant data for identifying different cultures. Groups are defined through kernel density estimation and a cluster analysis, followed by internal and external validation techniques. A third method characterizes the funerary ritual and grave-goods, using a similarity algorithm coupled with clustering procedures to compare the graves with one another. The outcome is validated with exploratory methods and compared to patterns from different contexts. The complementarity of the results shows that each approach sheds light on a certain facet of the same whole.     

Experimental Design and Experimental Inference in Stone Artifact Archaeology

Lithic researchers rely heavily on experimentation to infer past behaviors and activities based on stone artifacts. This paper explores the analogical nature of archaeological inference and the relationship between experimental design and inference validity in stone artifact experimentation. We show that actualistic flintknapping lacks vital aspects of scientific experimentation, and thus has inherent inferential issues of analogical adequacy and confidence. It is argued that a greater emphasis on hypothesis construction and variable control is needed in order to establish sound referential linkages upon which constructive analogic inferences about the past can be built.     

Maya Crocodilians: Intersections of Myth and the Natural World at Early Nixtun-Ch’ich’, Petén,Guatemala

This essay pursues a four-pronged, interdisciplinary approach in considering the possibility that the unusual layout of the lowland Maya site of Nixtun-Ch’ich’ in the lakes region of central Petén, Guatemala, might have been modeled on the scaly back of a crocodile. Part 1 summarizes the biological characteristics of crocodilians, particularly Crocodylus moreletii, and their habitats in lowland Mesoamerica. Part 2 reviews interpretations of these reptiles in myth and art, and exploitation of the creature in the lakes area. Third, the ceremonial core of Nixtun-Ch’ich’, established in the Middle Preclassic (800–400 BCE) period, is discussed. It exhibits an unusual grid of corridors creating a landscape resembling the bony plates of a crocodilian’s back, and a natural cenote-like fosa is proposed to relate to a mythical “Starry Deer Crocodile.” Part 4 discusses probable social and political characteristics of early community leaders who planned this site’s atypical layout, viewed through selectionist theories of cooperation and costly signaling. Designed to mimic the mythical crocodile of creation, Nixtun-Ch’ich’ illustrates the role of ideological power in the development of complex societies.     

Home Is Where the Hearth Is: Anthracological and Microstratigraphic Analyses of Pleistocene and Holocene Combustion Features,Riwi Cave (Kimberley,Western Australia)

The manipulation of fire is a technological act. The identification of the archaeological signatures of the controlled use of fire has important implications not only for the estimations of the origins and functions of the first fireplaces but also for our understanding of prehistoric technological development and resource use. At Riwi (Kimberley region, Western Australia), excavations over two field seasons have revealed a discontinuous occupation sequence over the past 45 ka, showing numerous, different combustion features interspersed within the deposit. Anthracological and micromorphological investigations at Riwi Cave indicate that the combustion features at the site can be categorised into three types: flat combustion features (type A), dug combustion features (type B) and thick accumulations of mixed combustion residues (type C). These provide evidence for two kinds of combustion practice: (i) fires lit directly on the ground and most likely not re-used and (ii) ground ovens, the latter appearing some 10,000 years after the first evidence for occupation of the site. A comparison of the wood species identified within these combustion features with those from equivalent scattered context levels, enables an exploration of the potential factors influencing wood selection and fire use through time at the site. A detailed understanding of the relationship between wood charcoal remains and archaeological context yields significant information on changes to environmental context and site occupation patterns over time.     

Between Monoculture and Cultural Polarization: Agent-based Models of the Interplay of Social Influence and Cultural Diversity

Social influence is one of the most important processes in human social interaction. Very often in human social interaction, influence is assimilative in that individuals become more similar to others they interact with. Nevertheless, cultural differences continue to remain in many realms of human life, for example, in the form of technological boundaries. Research on social influence points to a range of possible reasons for persistent cultural diversity, but there is much less clarity about the interplay of various factors and conditions for cultural influence with fundamental processes of social interaction at the micro-level. In this article, I show how agent-based computational modeling can be used as an approach for unraveling the complex interplay between simple first principles of interpersonal social interaction and emergent societal outcomes. I give a brief overview illustrating some of the main approaches agent-based modelers have developed in recent decades to understand conditions and processes of the emergence of cultural diversity. Models will be discussed that generate mainly cultural consensus as long-term behavior, but also models that generate clustering of cultural attitudes in geographical or social space, and models that imply cultural polarization with sharp cultural boundaries between emergent factions. It will be discussed how model dynamics depend on further assumptions, for example about random events, or the scaling of cultural attitudes, and what are further developments in the literature, possible future directions and challenges for the application of computational agent-based modeling in archeological research on cultural boundaries.     

A Comprised Archaeological History of Taiwan through the Long-Term Record of Heping Dao,Keelung

We present the results of six years of archaeological work carried out in Heping Dao, Keelung, northern Taiwan. The site has revealed a rich archaeological record spanning a sequence that comprehends most of the history of Taiwan, including the most salient historical landmarks in it. The study of this long-term sequence of habitation in Heping Dao throughout prehistory to current times, allows us to attempt a historical archaeology of the longue duree of the place that in turn enables the establishment of comparisons between periods and raising of specific questions, among them: the general understanding of cultural transformation along the Neolithic and the Iron Age, and in turn the transition Iron Age/Aboriginal historic times in Taiwan, which in our view has to be observed as a history of continuity rather than of interruptions; the recognition of the Chinese presence in Taiwan in the pre-European period; the implantation of the European colony and its effects on the local populations; the differing material remains and impacts caused by the presence of pre-European Chinese and the Qing occupation; and the potential for a comparison between the European and the Japanese colonial projects as seen in the material record.     

New Delhi’s All-India War Memorial (India Gate): Death,Monumentality and the Lasting Legacy of Empire in India

This paper traces the colonial and postcolonial histories of one of India’s most iconic structures, New Delhi’s All-India War Memorial. Designed and built by Edwin Lutyens immediately after the Great War, the memorial commemorated both Indian soldiers who had died in defence of the empire and the reason for such human sacrifice. As such the memorial reaffirmed and celebrated Britain and India’s unbreakable imperial bond, now strengthened by the fiery crucible of war. After independence in 1947, India took ownership of the memorial by renaming it India Gate to symbolise the country’s transition from what it had been to what it was becoming through India’s passion to be free. In the process, the memorial was re-evaluated and re-imagined in ways that transformed this site of unwelcome colonial memory into one of India’s most important symbols of national renewal. And yet this new interpretation remained as highly contested and problematic as its original colonial meaning. While the memorial became a site of national cohesion for many, it also perpetuated a colonial politics of division along communal (religious) and inter-communal (caste) lines that has eroded a sense of well-being and security for significant sections of the Indian community. Today, India Gate serves as a symbol of both national renewal and national fragmentation.     

The German Secret State Police in Spain: Extending the Reach of National Socialism

Germany encroached in Spain's internal affairs that followed providing military support the Spanish Civil War in the interest of pursuing National Socialist objectives through the establishment of an extensive apparatus of National Socialist organisations in Spain, including the Gestapo. Cooperation was officially established between Spanish and German police on 25 November 1937, which was extended to the Spanish political police on 31 July 1938, when they entered into a secret agreement with the German Gestapo for mutual assistance. The Gestapo trained the Spanish ordinary police and political police to contribute to maintaining the Franco regime in control of Spain, just as the Gestapo in Germany was charged with investigating and suppressing all forms of anti-state tendencies, and exported its methods and proceedings to Spain under the guise of contributing to the struggle against the alleged danger of worldwide communism. In addition to cooperation with Spanish police on suppressing dissent against the Franco regime, other functions related to serving the interests of National Socialist Germany, which deployed the Gestapo for various purposes while Spain constituted an extension of National Socialist Germany's sphere of influence. This was ensured through the Gestapo maintaining a presence in Spain until 1945.
