Show moreThis thesis presents an investigation into how geopolitical change and religious control are reflected in the composition of copper-alloy costume artefacts, recovered from Roman and early medieval contexts. It engages with the challenging topic of portable X-ray Florescence Spectrometry use in archaeology, especially as applied to corroded copper-alloy artefacts. The relevance is twofold. Firstly it helps us better understand the globalising effects of the Roman Empire on distant cultures and the emergence of the western economy after the end of antiquity. This is investigated by detecting changes in craft production, considered a proxy for understanding changes in past economies and societies. Secondly it advances a methodology for the study of copper-alloy objects. Subsequently the composition of Roman brooches from Germania Inferior, suggested a strong link between brass and Roman military production. This connection was also seen in other parts of the Roman world, suggesting a degree of centralisation or control. The earliest roman objects found in the Baltic States, far north of the Limes frontier, are also in this 'Roman' alloy. These objects had a lasting impact on the peoples of this region. They adopted and adapted them stylistically to suit their local preferences for centuries after they first appeared. Show less
