Maritime Archaeology in Uruguay: Towards a Manifesto

We report a collaborative maritime archaeological project in Uruguay, one of several Latin American countries where the subject is undergoing review in terms of the ways it is practised and managed. Uruguay is typical of many states where there has been a tension between a heritage-based approach in which the results of investigations are viewed as publicly owned, as opposed to the profit motive in which commercial and personal gain is the underlying ethic. This project was conceived both as a way of assisting the Uruguayan Heritage Commission in promoting the former approach as well as advancing a programme of research into the age of global exploration. This paper sets out the rationale of the initial field season and reflects on subsequent developments.     

Characterisation of obsidian subsource variability at El Paredón,Mexico

Portable X-ray fluorescence (pXRF) geochemical analysis on obsidian from five Formative period (1200 BCE to AC 100) sites from Tlaxcala, Mexico, has revealed that most of the material had similar values to those found in the closest obsidian source, named El Paredón, Puebla. Nevertheless, initial analyses did not resolve whether these materials came from the same caldera or from a specific obsidian deposit. Here we present a methodology that allows the identification of obsidian subsources. The results reveal that Tlaxcalan populations took advantage of a specific obsidian deposit called Tres Cabezas, Puebla, providing valuable new data to identify associated regional exchange networks.     

The Temple of the Fishermen: Early Ceremonial Architecture at Gramalote,a Residential Settlement of the Second Millennium B.C., North Coast of Peru

The archaeology of the Late Preceramic (3500–1800 b.c.) and Initial Periods (1800–800 b.c.) on the north coast of Peru is focused on monumental ceremonial buildings and little attention has been paid to small residential settlements. Here, I introduce the excavations carried out at Gramalote, a fishing settlement that was interpreted as a specialized producer of seafood with a narrow range of non-subsistence activities. Current data support a broader view of fishing communities during the second millennium b.c. in northern Peru. In this view, the discovery of a ceremonial facility at the Gramalote site opens a discussion about the role of community-level ceremonies and how these local practices are related to those at religious monumental centers of the same period.     

We are never alone: a conversation on bio art with Eduardo Kac

Brazilian-born artist Eduardo Kac’s (Rio de Janeiro, 1962) work has raised eyebrows especially for his ‘transgenic art’ projects, among others: Genesis, 1999; GFP Bunny, 2000; The Eight Day, 2001; Natural History of the Enigma, 2003/08. In all of these, Kac and his scientific collaborators realize genetic interventions into living organisms at the same time as they trigger audience reactions to these from playful kinds of interaction that is integrated into the works’ open and dynamic creative process. Yet whereas the ethical and political challenges Kac’s work poses have sparked lively debates within and beyond the realm of the arts – can and must art engage with the ‘creative’ potentials of biotechnology and genetics? Do these not in fact (as Vilém Flusser and others have suggested) hold the key to realizing the vanguardist dream of merging art and life? Or should the artist, from the vantage point of his own creative practice, not rather warn us against the ethical and political risks involved in genetic engineering? – much less attention has been paid to the way Kac’s art also continues and transforms a particular legacy of post-concretist, ambient and performance art in Latin America.

Kac himself has referred to Brazilian artists Flávio de Carvalho, Hélio Oiticica and Lygia Clark as informing his interest in open, participative forms, which characterize both his transgenic and his earlier ‘tele-presence’ art projects. Other Latin American artists of the late twentieth and early twenty-first century have been producing intriguing engagements with living materials, multispecies habitats and organic remains, including such diverse names as Luis Fernando Benedit, Nicola Constantino, Nuno Ramos, or Teresa Margolles. In a conversation with Jens Andermann and Gabriel Giorgi at the University of Zurich’s Center of Latin American Studies on March 12, 2015, Kac addressed the way in which his work might be seen as continuing or challenging long-standing representations of the New World as a repository of ‘nature’, from colonial chronicles of discovery to contemporary discourses of biodiversity and conservation. To what extent is bio art – and the questions it raises about the Anthropocene as a threshold of radical biopolitical convergence between ‘history’ and ‘nature’ – necessarily ‘transcultural’ and planetary in its extension?     

Curated Ruins and the Endurance of Conflict Heritage

Abstract

Architectural ruins created by bombing, artillery, and fire are a common feature of post-conflict urban and extra-urban environments, serving as stark reminders of the material impact of warfare and violence. Over time most of these ruins are either restored, demolished, or reclaimed by nature. This paper examines another, more unusual category: sites that are carefully maintained in a freshly ruined state, suggesting that their destruction was more recent than it actually was. These sites — most often configured as memorials — raise interesting questions about memorialization, conflict heritage, authenticity, ethics, and whether or not there is a ‘natural’ lifespan or lifecycle for architectural ruins. To illustrate this argument I will draw on case studies of the Frauenkirche in Dresden, Germany, and the ruins of Oradour-sur-Glane in France.     

Standing at the gates of Europe: Human behavior and biogeography in the Southern Carpathians during the Late Pleistocene

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.
