Cultural,Demographic and Environmental Dynamics of the Copper and Early Bronze Age in Iberia (3300–1500 BC): Towards an Interregional Multiproxy Comparison at the Time of the 4.2 ky BP Event

This paper presents the first comprehensive pan-Iberian overview of one of the major episodes of cultural change in later prehistoric Iberia, the Copper to Bronze Age transition (c. 2400–1900 BC), and assesses its relationship to the 4.2 ky BP climatic event. It synthesizes available cultural, demographic and palaeoenvironmental evidence by region between 3300 and 1500 BC. Important variation can be discerned through this comparison. The demographic signatures of some regions, such as the Meseta and the southwest, diminished in the Early Bronze Age, while other regions, such as the southeast, display clear growth in human activities; the Atlantic areas in northern Iberia barely experienced any changes. This paper opens the door to climatic fluctuations and inter-regional demic movements within the Peninsula as plausible contributing drivers of particular historical dynamics.     

Between Virgins and Priests: The Feminisation of Catholicism and Priestly Masculinity in Nineteenth-Century Spain

The feminisation of religion in the nineteenth-century has been broadly discussed by historians and sociologists. Considering the main contributions of that debate from a critical perspective, this article defends the hypothesis that the Catholic Church identified itself with the same characteristics with which it defined femininity in the nineteenth-century through the symbolic link with the Virgin Mary. Although this discursive feminisation of Catholicism left laymen in a difficult situation, it did contribute to reinforcing the patriarchal and hierarchical structure of the Church. The great challenge to bishops and priests, the leading subjects in the project of re-Christianising society, was to demonstrate their condition as men within a feminised organisation. This article will mainly focus on Spain, although with the international perspective that any study about Catholicism requires.     

Modes of knowing: Perceiving and living toxicity in Ecuadorian Amazonia

Located in Ecuador's southern Amazonia, the Condor Mountain Range is the home of the Shuar people, who have been living for the last three decades amid increasing colonization and expanding mineral extraction. In these mined lands, gold is constantly brought into being through chemical manipulations. After state authorities declared the valleys a zone of environmental destruction, these chemical compounds in soils, waters and bodies have been widely documented. The Shuar villagers are concerned with the evident destructive effects of cyanide on aquatic life. However, the invisible hazardous effects of mercury and manganese, the evidence of which can be sensed neither in fish's flesh nor on their bodies, remain unsettled. This article explores how toxic chemicals are made perceptible or imperceptible. Toxicological and biomedical knowledge practices produce (im)perceptibility through chains of associations and disassociations. Such practice intertwines with colonization projects that ignore the importance of fish and fishing to the Shuar.     

New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates

The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date probability density curves, as a proxy to show the spatial dynamics of the last hunter-gatherers and first farmers. Several scholars have pointed out problems linked with the variability of samples, such as the overrepresentation of some sites, the degree of regional research, the nature of the dated samples and above all the archaeological context, but we are confident that the selected dates, after applying some filters and statistical protocols, constitute a good way to approach settlement spatial patterns in Iberia at the time of the neolithisation process.     

Fluvial spatial taphonomy: a new method for the study of post-depositional processes

Traditional taphonomic analyses do not consider the emergent properties resulting from the relationship of variables. Several of these emergent properties are expressed spatially. Here, we present a spatial taphonomic approach to the understanding of post-depositional processes affecting experimental assemblages modified by fluvial currents. Spatial statistical methods are a great tool to understand how different taphonomic variables relate at a spatial scale. The results of the application of this method to bone assemblages affected by low- and high-energy flows show the loss or modification of most of the original spatial taphonomic relationships. It also shows the degree of bone loss according to element, anatomical section and bone structure, and shape types. Anisotropy is identified in both experimental contexts. These results add new criteria to assess the impact of water flows in bone assemblages and contribute to define the properties of lag assemblages.     

X-ray and neutron-based non-invasive analysis of prehistoric stone artefacts: a contribution to understand mobility and interaction networks

Carbonate-rich archaeological artefacts are difficult to identify and correlate between them and with raw materials of such heterogeneous geological sources, especially when only non-invasive analysis is possible. A novel combination of X-ray and neutron-based non-invasive analysis is implemented and used for the first time to study prehistoric stone idols and vessels, contributing to culture identity, mobility and interaction in the recent Prehistory of Southern Iberia. Elemental composition was obtained by prompt gamma activation analysis (PGAA) and external beam particle-induced x-ray emission (PIXE); homogeneity of the stone artefacts and the presence/absence of internal fractures were obtained by neutron radiography (NR). These atomic and nuclear techniques, simultaneously used for complementary chemical information, have been demonstrated to be of great value as they provide non-destructive compositional information avoiding sample preparation, crucial in so singular and rare objects. The obtained results, especially of PGAA, are very promising and useful in general assessments of provenance. The stone artefacts show signs of both nearby and long-distance procurement, as well as of unknown attribution.     

Technological aspects of Mesopotamian Uruk pottery: estimating firing temperatures using mineralogical methods,thermal analysis and luminescence techniques

The Middle Uruk phase in Mesopotamia (3600–3500 bc) has been characterised by the massive production of “bevelled rim bowls” (BRBs). They are characterised by their similar shape and volume in Mesopotamia and surroundings. However, their production method has not been studied in detail, including the firing temperature. The determination of the firing temperature of ancient pottery has been attempted by studying mineral phase transformation sequences; although, very little knowledge exists about such transformations in mixtures or thermal analyses. These methods usually provide imprecise firing temperatures between 500 and 800 °C, as other factors such as the raw materials or firing time and conditions must be considered. As an alternative, luminescence techniques have been tested with promising results, as they have provided reliable maximum firing temperatures for ancient pottery at mild conditions (below 600 °C) with high precision. In this work, the firing temperatures of BRB samples from two archaeological sites located in the Middle Euphrates Valley (Syria) have been studied using mineralogical, chemical and thermal analysis. Both mineral characterization techniques and thermal analyses show agreement and firing probably below 600–700 °C. Luminescence yields ambiguous results but circumstantial evidence on the firing temperature between 400 and 550 °C.
