“…To enable detailed observations, it was necessary to classify several wear categories, building upon earlier work (Bridgford, 1997;2000;Dolfini, 2011;Horn, 2013;Molloy, 2008;Molloy et al, 2016;Contributions in Uckelmann and Mödlinger, 2011). The formation of damage depends upon complex processes involving material properties (for example hardness, toughness, malleability, tensile strength, etc.…”

The article is based on wear analysis carried out on 101 bladed objects including swords, spears, daggers, and knives. They are dating mostly to the Early Nordic Bronze Age. Wear marks vary over time and for each object category. The data are discussed to investigate the implications of the variation in the wear patterns. It is argued that a true specialization of the combat roles of swords and spears occurs first during the advanced Early Bronze Age. This may lead to the gradual loss of the role daggers had in combat. This is interpreted as evidence that the design and use of bladed objects inform each other and cause gradual changes.

“…Fourthly, the development of use-wear analyses on Bronze Age objects is starting to see more widespread application as are better recording systems, fewer untested assumptions, and a greater awareness of the complexities of interpretations (see Dolfini and Crellin 2016;Gutiérrez-Sáez and Martín-Lerma 2015;Horn 2013;Kristiansen 1978Kristiansen , 1984Kristiansen , 2002Kristiansen and Suchowska-Ducke 2015;Kuijpers 2017Kuijpers , 2018Molloy 2008Molloy , 2009Molloy , 2010Molloy et al 2016;Roberts and Ottaway 2003;Uckelmann and Mödlinger 2011). What is required is an approach to analyzing and understanding Bronze Age metal circulation and use that can evaluate and further advance the established models and interpretations based on morphologies, typologies, and distributions of Bronze Age copper and bronze objects throughout Europe.…”

The Provenance, Use, and Circulation of Metals in the European Bronze Age: The State of Debate

Bronze is the defining metal of the European Bronze Age and has been at the center of archaeological and science-based research for well over a century. Archaeometallurgical studies have largely focused on determining the geological origin of the constituent metals, copper and tin, and their movement from producer to consumer sites. More recently, the effects of recycling, both temporal and spatial, on the composition of the circulating metal stock have received much attention. Also, discussions of the value and perception of bronze, both as individual objects and as hoarded material, continue to be the focus of scholarly debate. Here, we bring together the sometimes-diverging views of several research groups on these topics in an attempt to find common ground and set out the major directions of the debate, for the benefit of future research. The paper discusses how to determine and interpret the geological provenance of new metal entering the system; the circulation of extant metal across time and space, and how this is seen in changing compositional signatures; and some economic aspects of metal production. These include the role of metal-producing communities within larger economic settings, quantifying the amount of metal present at any one time within a society, and aspects of hoarding, a distinctive European phenomenon that is less prevalent in the Middle Eastern and Asian Bronze Age societies.

“…These have been extensively used for archaeological site prospection (see papers in Opitz and Cowley) [27]. At the other end of the spectrum, 3D scanning using desktop and terrestrial laser scanning have been used to capture surface features on monuments and minute microware patterns on artefacts [28]. Such tools have been used to explore surface rockiness before [29], but while they are highly effective, both techniques are expensive when compared to the models derived using UAV imagery and an SfM pipeline.…”

Abstract:The application of high-resolution imagery from unmanned aerial vehicles (UAV) to classify the spatial extent and morphological character of ground and polished stone tool production at quarry sites in the Shetland Islands is explored in this paper. These sites are manifest as dense concentrations of felsite and artefacts clearly visible on the surface of the landscape. Supervised classification techniques are applied to map material extents in detail, while a topological analysis of surface rugosity derived from an image-based modelling (IBM) generated high-resolution elevation model is used to remotely assess the size and morphology of the material. While the approach is unable to directly characterize felsite as debitage, it successfully captured size and morphology, key indicators of archaeological activity. It is proposed that the classification of red, green and blue (RGB) imagery and rugosity analysis derived from IBM from UAV collected photographs can remotely provide data on stone quarrying processes and can act as an invaluable decision support tool for more detailed targeted field characterisation, especially on large sites where material is spread over wide areas. It is suggested that while often available, approaches like this are largely under-utilized, and there is considerable added value to be gained from a more in-depth study of UAV imagery and derived datasets.
