Hestia2 is pleased to announce a free one-day seminar at the University of Southampton on spatial network analysis in archaeology, history, cultural heritage and commercial archaeology. Spatial relationships are everywhere in our sources about the past: from the ancient roads that connect cities, or ancient authors mentioning political alliances between places, to the stratigraphic contexts archaeologists deal with in their fieldwork. However, as datasets about the past become increasingly large, these spatial networks become ever more difficult to disentangle. Network techniques allow us to address such spatial relationships explicitly and directly through network visualisation and analysis. This seminar aims to explore the potential of such innovative techniques for research, public engagement and commercial purposes.
