The Wadi al‐Hijr (Sultanate of Oman) in the third millennium BC

In 2010–11 a pedestrian survey of the western end of Wadi al‐Hijr in northern Oman identified 1507 archaeological features in a 124 km² area. Data were collected on each feature's architectural characteristics, associated artefact assemblages, topographic and environmental locations, condition of remains, and relations to other archaeological features. The majority of datable features belong to the third millennium BC and divide unequally between the Hafit and Umm an‐Nar periods. While the majority of these third‐millennium BC features were tombs, other feature types were identified, including towers, settlements, quarries, dams, enclosures, and possible platforms. Third‐millennium BC features were organised into clusters and ranged considerably in size, from a few features to several hundred. All of the clusters established during the Hafit period were maintained in the Umm an‐Nar period, suggesting a continuity throughout the third millennium. Some preliminary hypotheses regarding settlement patterns are suggested.     

Governing urban regeneration in the UK: a case of ‘variegated neoliberalism’ in action?

The article focuses on the redevelopment of previously developed land by public-private sector partnerships in three cities/towns in South-West England, two of which can be described as medium-sized places with little previous experience of such developments. In each case we situated the redevelopment process in its wider multi-level and horizontal relationships using Social Network Analysis to produce network and centrality maps to reveal the complex network of relationships the process was embedded within and shaped by. These developments took place in what is termed the ‘roll-out’ phase of neoliberalism and we illustrate how the overarching planning and regulatory regimes (including contracts), along with wider economic conditions, shaped the development process, with the proviso that in each case these factors were mediated and themselves shaped by the assortment and interaction of local organizational, political, economic and civic forces. These included local planning committees and their interpretation of planning regulations and the developers involved, but also opposition to the developments from local sources. Much, however, depended on the ‘capacity to act’ of the relevant partnerships, in the sense of mobilizing and deploying available resources to realize the proposed developments.     

Analysis of Heavy Metals in Smoke Deposits in the Limewash of the Royal Artillery Factory of Seville (17th Century): Contributions to the Location of the Furnaces

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes.     

Quantifying artefacts over time: Interval estimation of a Poisson distribution using the Jeffreys prior

This paper presents a new method for estimating the amount of an artefact class in use at a given moment in the past from a random assemblage of archaeological finds. The method is based on the use of simulation, since an analytical solution is computationally impractical. Estimating the number of artefacts in use at any time t is shown to follow a Poisson distribution, which allows for credible intervals to be established using the Jeffreys prior. This estimator works from minimal assumptions about the dating and duration of finds, as well as the intensity of collection, and is applied to coinage from four Roman‐period sites excavated by the Roman Peasant Project (2009–14). The result provides an estimation of the abundance of material according to an interval of certainty.     

Orientation of the Romanesque churches in the region of Val d’Aran,Spain (11th–13th centuries)

This study examines an ensemble of Romanesque churches in the region of Val d’Aran in the Spanish Pyrenees, built between the 11th and 13th centuries. Seven topographical studies performed between 2014 and 2015 examined these churches systematically using terrestrial laser scanning (TLS) as a data‐acquisition technique. The data obtained allowed for a geometrically accurate analysis of the orientation of these churches based on four Romanesque liturgies: Gemma animae (c.1120), by Honorius of Autun; Rationale divinorum officiorum (c.1150), by Jean Beleth; Mitralis de Officio (1190), by Sicard, Bishop of Cremona; and Prochiron, vulgo rationale divinorum officiorum (1291), by Guillaume Durand.     

NMR as a new tool for cultural heritage application: The provenance of ancient white marbles

Identifying the origin of marble used in antiquity brings back to light details of the economic, social and political organization of classical societies, and characterizing in depth the chemistry of marble is key to discovering its provenance. Beyond X‐ray diffraction, which could reveal the presence of discriminant secondary crystalline phases and the quantification of accessory minerals combined with a multivariate analysis approach, solid‐state nuclear magnetic resonance (NMR) enables one to recognize the local structure arrangement of both crystalline and amorphous materials by looking at one or more selected atoms. In present paper targets the ¹³C nuclide, and thus the major component of marble, calcium carbonate. Whatever their geological origin, marbles ¹³C‐NMR spectra present only one resonance corresponding to the carboxyl function whose intensity and line width vary from one marble to another. If the variation of the NMR signal intensity observed is the result of great T1 variations (from 220 to 5300 s) and is linked to iron content, the line width reflects defects in the calcite crystal in which calcium has been replaced by another element such as magnesium, aluminium or strontium. The specific profile of the NMR signal has been used successfully to help determine the origin of some archaeological items.
