Introducing δSr analysis in archaeology: a demonstration of the utility of strontium isotope fractionation in paleodietary studies

Isotopic methods are widely used in archaeology to investigate paleodiet. Here, we present a new method to identify trophic level in archaeological human populations and to investigate paleodiet. We demonstrate that strontium isotope compositions (reported as δ^88/86Sr) vary in a mass-dependent manner with increasing trophic level and can elucidate paleodiet in archaeological human populations. We present new mass-dependent strontium isotope data from tooth enamel and bone from individuals buried during the Late Intermediate Period (c. AD 1000–1300) in the large cemeteries of Chiribaya Alta, Chiribaya Baja, San Gerónimo, and El Yaral in the Ilo and Moquegua Valleys of southern Peru. We compare these data to radiogenic strontium isotope data (⁸⁷Sr/⁸⁶Sr) and light stable isotope data (δ¹⁵N_col and δ¹³C_col) from the same individuals to investigate geologic variability in strontium sources as well as marine food consumption among the Chiribaya. Our results demonstrate the utility of measurements of strontium isotope fractionation as a new tool for archaeological investigation of paleodiet. Importantly, this new technique can be used to generate paleodietary (δ^88/86Sr) and paleomobility (⁸⁷Sr/⁸⁶Sr) data from the same specimen, minimizing destructive analyses of invaluable archaeological material, and provides a new way to examine paleodiet through hydroxyapatite, which is particularly important when collagen is poorly preserved.     

The Muddle in the Middle Pleistocene: The Lower–Middle Paleolithic Transition from the Levantine Perspective

The terms Lower Palaeolithic and Middle Palaeolithic represent research constructs within which cultural evolution and prehistoric hominin behaviours can be studied, with the transition usually understood as marking a watershed in our evolution: an adaptation with a million-year record of success that gives way to something new. The interpretation of the Lower Palaeolithic Acheulian technocomplex is usually understood as a period of cultural stasis that extends over much of Africa and Eurasia, principally associated with Homo erectus. Those innovations that can be observed occur widely separated from one another in space and time. Yet a closer and more detailed examination of the Middle Pleistocene records from East Africa, southern Africa, Europe and the Levant reveals significant variation in cultural repertoires. A kind of paradox emerges, in which an Old World Lower Palaeolithic, apparently lacking an overall dynamic of distinctive and directed change in terms of cumulative variation over time, nevertheless culminates in a transition which sees the universal appearance of the Middle Palaeolithic. The two main hypotheses that have been advanced to explain the global transition, which happens essentially synchronously, appear mutually exclusive and contradictory. One view is that altered climatic-environmental constraints enabled and encouraged an ‘Out-of-Africa’ dispersal (or dispersals) of a new type of genus Homo. This cultural replacement model has been challenged more recently by the alternative hypothesis of accumulating but unrelated and temporally non-linked regional, and in fact potentially autochthonous, processes. The Levant, by virtue of its position bridging Africa and Eurasia (thus being the region into which any out-of-Africa groups would have had first to disperse into), must be seen as a critical region for assessing the relative merits of these competing hypotheses. This paper deals with the Lower–Middle Paleolithic boundary in the Levant within a long temporal perspective. The Middle Pleistocene record in the Levant enables us to examine the amplitude of variation within each techno-complex, as well as to question whether there are diachronic changes in the amplitude of techno-typological variations as well as changes in the manner by which they appear in the record. The results carry significant implications for understandings of demographic and societal processes during the Lower–Middle Paleolithic transition in the Levant.     

Making time: ‘Living floors’, ‘palimpsests’ and site formation processes – A perspective from the open-air Lower Paleolithic site of Revadim Quarry, Israel

The recognition of the dynamic role of site formation processes led archaeologists to recognize a behavioral dichotomy between ‘living floors’ and palimpsests’, Yet the archaeological proxies of ‘living floor’ and ‘palimpsest’ were never defined formally, and therefore have been used variably. We use archaeological criteria mentioned in the archaeological literature to model types of formation processes. The case study of the Lower Paleolithic open-air site of Revadim Quarry, Israel is used to test the model. Two types of palimpsests, differing in the rate of accumulation and thus in their effects on the anthropogenic remains, were discerned. Based on these results we review some other Lower Paleolithic instances. A sliding scale of formation processes provides a much needed middle ground between the scales of coarse, time-averaged formation processes and short, “near real-life” behavioral episodes and is an appropriate archaeological frame of reference.     

Courses of Conflict: Transmission of Knowledge and War's History in Eastern Sri Lanka

After three decades of armed confrontations, the Sri Lankan civil war ended in May 2009 with the military defeat of the liberation tigers of Tamil Eelam (LTTE). To sustain the war for so long, mechanisms of knowledge reproduction were used legitimizing violence and assuring the conflict's transmission across the generations involved in it. Drawing on ongoing fieldwork in the island's Eastern Province, this article addresses the processes through which Sri Lanka's war-history has been taught and learnt, empirically linking the multiple sites of knowledge transfer. It suggests a trajectory moving from the institutional (policy and textbooks) to the defiant (specific schools and armed movements) spaces of transmission, while comparing the attitudes, memories of violence and transmission strategies of educators, students and former combatants. The data are embedded within the broader discussions on social change and the cultural reproduction of war, a process illustrated with the help of a new concept: semantic alliances.     

To die for country, land or faith in Castilian medieval thought

This is an analysis of the concept of patria in the Castilian sources of the period between the twelfth and the fifteenth centuries. These texts show that, contrary to the opinion of Nieto Soria, patria did not have the same connotations as in other regions of the late medieval west. Until the fifteenth century at least, ‘country' and ‘land' were seen as largely synonymous in Hispanic thought. ‘To die for the land and for the faith' seems to have been the essential ideological justification for those fighting the Muslim enemy.     

Decolonising Indonesia,Past and Present

ABSTRACT

In the pursuit of an “authentically Indonesian” nation-state, for decades Indonesians have denied the civil rights of fellow citizens for allegedly being less authentically Indonesian. A key to the longstanding efficacy of such exclusionary ethno-nationalism is the failure to recognise the trans-national solidarity that helped give birth to independent Indonesia. Such solidarity is best illustrated in the extraordinary case of the making in Australia of a documentary film, Indonesia Calling (1946). A starting point of this article is the proposition that Indonesia’s cultural politics of the past and its future is never free from a protracted battle over what the nation is allowed, or willing, or able to forget and remember from its past. Mere disclosure of Indonesia’s past history with its cosmopolitan features will not necessarily lead to changes for the better in contemporary Indonesia, especially if the new revelation runs counter to the interests of those in power. Nonetheless, no substantial and long-term change for the better is possible for Indonesia without serious, open, critical re-examination of the revolutionary making of the Republic, and due acknowledgment that inauthenticity, plurality and trans-national solidarity are the hallmarks of the process.
