This volume presents a new approach to decorative practices in Iron Age Britain and beyond. It aims to collapse the historic distinction between art and craft during the period 400BC-AD100 by examining the purposeful nature of decoration on varied Iron Age objects, not just those traditionally considered art. A case study from East Yorkshire (UK), a region well known for its elaborate Iron Age metalwork, is presented. This study takes a holistic approach to the finds from a sample of 30 sites, comparing pattern and plainness on objects of a wide range of materials. The analysis focuses on the factors that led makers to decorate certain objects in certain ways and the uses of different patterns in different social contexts. A concentrated study on evidence for use-wear, damage, repair and modification then draws on primary research and uses assemblage theory to better understand the uses and functions of decorated objects and the ways these developed over time.
