Rethinking Iberian 'Warrior' Stelae: A Multidisciplinary Investigation of Mirasiviene and Its Connection to Setefilla (Lora del Río, Seville, Spain)

Iberian ‘warrior’ stelae have captured the imagination of researchers and the public for more than a century. Traditionally, stelae were considered ‘de-contextualised’ monuments, and research typically focused on the study of their iconography, paying little or no attention to their immediate contexts. As a result, despite the large number of these stelae known to date (c. 140) and the ample body of literature that has dealt with them, fundamental questions remain unanswered. This paper aims to demonstrate the potential of a multidisciplinary and contextual approach to push forward the research agenda on these monuments through a case study. Firstly, we introduce the Mirasiviene stela and the methods deployed for its investigation, which include a variety of digital imaging techniques, petrography, pXRF, intensive survey and multiscalar spatial analysis. Secondly, we discuss the results in relation to three main topics: stela biography, social practices and landscape context. Comparisons to the well-known nearby Bronze Age and Iron Age site of Setefilla are made throughout the discussion. Ultimately, this paper makes a case for the stelae of Mirasiviene and Setefilla being polyvalent monuments made by local artisans, that served both as landmarks and memorials in connection with dense late second and early first millennium BCE settlement patterns in the region. Probably linked to elites, ‘houses’ or kin groups of this time, stelae were set in symbolically charged places, liminal spaces nearby water, burials and pathways, attracting a range of ritual activities throughout the centuries. The study of the newly discovered Mirasiviene stela shows that multidisciplinary, cutting-edge non-destructive archaeology can shed significant new light on these prehistoric monuments, thus providing a glimpse of what in our opinion is a paradigm shift in the research of similar monuments throughout Europe

Assembling the Dead, Gathering the Living: Radiocarbon Dating and Bayesian Modelling for Copper Age Valencina de la Concepción (Seville, Spain)

The great site of Valencina de la Concepción, near Seville in the lower Guadalquivir valley of southwest Spain, is presented in the context of debate about the nature of Copper Age society in southern Iberia as a whole. Many aspects of the layout, use, character and development of Valencina remain unclear, just as there are major unresolved questions about the kind of society represented there and in southern Iberia, from the late fourth to the late third millennium cal BC. This paper discusses 178 radiocarbon dates, from 17 excavated sectors within the c. 450 ha site, making it the best dated in later Iberian prehistory as a whole. Dates are modelled in a Bayesian statistical framework. The resulting formal date estimates provide the basis for both a new epistemological approach to the site and a much more detailed narrative of its development than previously available. Beginning in the 32nd century cal BC, a long-lasting tradition of simple, mainly collective and often successive burial was established at the site. Mud-vaulted tholoi appear to belong to the 29th or 28th centuries cal BC; large stone-vaulted tholoi such as La Pastora appear to date later in the sequence. There is plenty of evidence for a wide range of other activity, but no clear sign of permanent, large-scale residence or public buildings or spaces. Results in general support a model of increasingly competitive but ultimately unstable social relations, through various phases of emergence, social competition, display and hierarchisation, and eventual decline, over a period of c. 900 years
