Fiona Edmonds visited the Centre for Advanced Welsh and Celtic Studies, Aberystwyth, in order to deliver a seminar about the project. The seminar began with a discussion of the key concepts underpinning the project and a summary of the work conducted to date. Fiona then gave a more detailed exposition of her thoughts about contact between Britain and Brittany during the Viking Age. She highlighted the political reorientations of the period, including new connections with England. Nevertheless, she argued for the persistence of the concept of the pan-Brittonic world ‘o Vynaw hyt Lydaw’ during this complex period.
