Who was St Columba? How did this Irish aristocrat become the most important figure in early Scottish Christianity?This book examines the different roles played by the saint in life and death, tracing his career in Ireland and Scotland, where we encounter not only Columba the abbot and missionary but also Columba the politician and peacemaker. We see him at the centre of a major controversy which led to his excommunication by an Irish synod. We follow him then to Scotland, to Iona, where he founded his principal monastery. It was from this small Hebridean isle that he undertook missionary work among the Picts and had dealings with powerful warrior-kings. It was from Iona, too, that his cult was vigorously promoted after his death in 597, most famously by Abbot Adomnan, whose writings provide our main source of information on Columba's career. The final chapters of the book look at the evolution of the cult of Columba from the seventh century onwards.

St Columba is one of the most important figures in the early history of the British Isles. A native of Donegal and a nobleman of royal ancestry, his outstanding religious career spanned both sides of the Irish Sea. On the Scottish island of Iona he founded his principal monastery where he served as abbot until his death in AD 597. Iona eventually became the centre of a powerful federation of monasteries that preserved a memory of Columba and nurtured the saintly cult that grew around him.Drawing on contemporary sources – particularly the writings of Adomnán, abbot of Iona from 679 to 704 – and the latest modern research, this book traces Columba's achievements and legacy. It examines his roles as abbot, scholar and missionary as well as his involvement in the affairs of kings in both Ireland and northern Britain.
