This compilation of 13 papers by scholars from Ireland, England and Denmark, consider the extent and nature of Viking influence in Ireland. Created in close association with exhibitions held at the National Musem of Ireland in 1998-99 and at the National Ship Museum in Roskilde in 2001, the papers discuss aspects of religion, art, literature and placenames, towns and society, drawing together thoughts on the exchange of culture and ideas in Viking Age Ireland and the extent to which existing identities were maintained, lost or assimilated.
