A collection of 27 articles on cultural interactions between Ireland, Britain and the Continent during the early Middle Ages. The pivotal role of Ireland in the development of a decidedly Christian culture in early medieval Europe has long been recognized. Still, Irish scholarship on early medieval Ireland has tended not to look beyond the Irish Sea, while continental scholars try to avoid Hibernica by reference to its special Celtic background. Following the lead of the honorand of this volume, Prof. Dáibhí Ó Cróinín, this collection of 27 essays aims at contributing to a reversal of this general trend. By way of introduction to the period, the first section deals with chronological problems faced by modern scholars as well as the controversial issues relating to the reckoning of time discussed by contemporary intellectuals. The following three sections then focus on Ireland's interaction with its neighbours, namely a) Ireland in the Insular world, b) continental influences in Ireland, and c) Irish influences on the Continent. The concluding section is devoted to modern scholarship and the perception of the Middle Ages in modern literature.
