Networks and the Spread of Ideas in the Past: Strong Ties, Innovation and Knowledge Exchange gathers contributions from an international group of scholars to reconsider the role that strong social ties play in the transmission of new ideas, and their crucial place in network analyses of the past.Drawing on case studies that range from the early Iron Age Mediterranean to medieval Britain, the contributing authors showcase the importance of looking at strong social ties in the transmission of complex information, which requires relationships structured through mutual trust, memory, and reciprocity. They highlight the importance of sanctuaries in the process of information transmission, the power of narrative in creating a sense of community even across geographical space, and the control of social systems in order to facilitate or stifle new information transfer.Networks and the Spread of Ideas in the Past demonstrates the value of searching the past for powerful social connections, offers us the chance to tell more human stories through our analyses, and represents an essential new addition to the study and use of networks in archaeology and history. The book will be useful to academics and students working in the Digital Humanities, History, and Archaeology.
