1 DRAFT. NOT FOR CITATION Forthcoming in Chaniotis, A. And Ducrey, P (eds.) The Role of Emotions in Classical Antiquity. Stuttgart: Steiner Verlag. Material values: emotion and materiality in ancient Greece Lin Foxhall, University of Leicester This paper derives from work I am doing as part of a major research programme (www.tracingnetworks.ac.uk ) funded by the Leverhulme Trust which combines archaeology and computer science. In nine linked projects (seven in archaeology and two in computer science), we are utilizing semantic web technologies to revolutionize data management in archaeology, and applying archaeological methodologies to systems design in order to improve the movement of information in future computer systems. We are investigating how knowledge, especially the technological knowledge of how to make things, moves around the ancient Mediterranean world between the late bronze age and the Hellenistic period, and the networks of human relationships through which this knowledge moves and develops. We are asking: • How does technical knowledge move from one person/group/society to another? • How do people choose which particular knowledge to use from the repertoire available? • In what kinds of contexts does innovation appear? • How can the networks of human relationships through which knowledge moved in the past contribute to digital knowledge transmission today? All of the projects in the research programme are drawing on two common methodologies: the chaîne opératoire and cross-craft interaction. The chaîne opératoire is a technique widely used by scholars of early prehistory, and entails tracking the life-course of an object from the procurement of raw materials through every stage of its manufacture, use, consumption, dissemination, exchange, re-use, re-cycling and disposal. Cross-craft interaction is the way in which ideas jump from one craft to another, so that by studying multiple crafts together we can explore their social and technological impact on each other. These methodologies allow us to develop comparisons across cultures and over time, and across disciplines, to set technologies in their social contexts, and to explore networks of knowledge. Craft traditions can therefore be viewed as tools of communication, implemented through human relationships and linked to personal and group identities. My own research within the project concerns networks of women and their relationships with each other via weaving, which I am addressing by studying loom weights. The
