The earliest evidence of blue pigment use in Europe Open
Blue pigments are absent in Palaeolithic art. This has been ascribed to a lack of naturally occurring blue pigments or low visual salience of these hues. Using a suite of archaeometric approaches, the authors identify traces of azurite on …

Fold it Open
A few years ago, an article on Roman folding knives in Denmark would have been unfeasible, as this small and distinct group of artifacts had not yet been identified. However, the increasing use of metal detectors in Denmark has led to the …

A Collaborative Approach to the Analysis of Northwest Coast Treasures from the Ehlers Collection in Denmark Open
The paper examines three late nineteenth–early twentieth century Pacific Northwest coast objects—a Nuu-chah-nulth kuxmin (bird rattle), a Haida sGaaga (medicine man) figure, and a Kwakwaka’wakw or Wuikinuxv wooden model of a totem pole—fro…

The CHIPS Database: A Repository for Reference Data on Chemical Analysis in Archaeometallurgy of Iron Open
This preprint presents the core concepts of the CHIPS database, the project of a global repository of reference chemical data related to the archaeometallurgy of iron. Archaeometallurgists interested in iron do not currently have access to…

Evaluating the suitability of lithic illustrations in morphometric analyses Open
Illustrations of lithic artefacts are an abundant source of morphological and technological information for those interested in our human past, trusted as faithful reproductions of the selected artefacts in question. Despite the considerab…

THE IDENTIFICATION OF EMOTIONS AND JURY DECISION MAKING Open
This study investigated the impact of a defendant’s emotions, expressed through gait and displayed through video footage, on jury decision making. The degree of state empathy and the case-related judgements of the mock jurors were assessed…

ROME'S Rise to Power. Geochemical Analysis of Silver Coinage from the Western Mediterranean (Fourth to Second Centuries BCE) Open
We present the results of geochemical analysis of silver coinage issued by Rome and dated between the fourth and second century BCE, which are complemented by data of coinage issued by Carthage, the Brettii, and the Greek colony of Emporio…

Multi-classifier majority voting analyses in provenance studies on iron artefacts Open
The main objective of this paper is to propose an approach for identification of provenance of archaeological iron artefacts making use of major oxides and trace elements. For this purpose, seven classifiers were built on the basis of the …

Retracing Magna Graecia's silver: coupling lead isotopes with a multi‐standard trace element procedure Open
This study presents the results of compositional and lead isotopic analysis of coinage issued by the Greek colonies of Syracuse, Metapontum, Taras and Thurium in the fifth to third centuries bce . The data suggest that each colony in Magna…
