The Practicalities of Communication between Northumbrian and Irish Churches, c.635–735
This chapter examines the relation between Northumbrian and Irish churches during the period between 635 and 735. It suggests that the journeys of churchmen between Ireland and Northumbria were in some ways inextricably linked with those of their lay counterparts and that the development of major ecclesiastical establishments during the seventh and early eighth centuries added a new dimension to trans-Irish Sea contact. The chapter also explains why the trans-Irish Sea contact did not cease in 664 when formal links between Lindisfarne on the one hand, and Iona and the Columban churches in Ireland, on the other, were terminated.
