was abbot of Iona (679–704), hagiographer, statesman and clerical lawyer; he was the author of the most important Vita of Saint Columba and promulgator of the "Law of Innocents", lex innocentium, also called Cáin Adomnáin, "Law of Adomnán". In Ireland, especially in Derry and County Donegal, a popular Anglicised form of his name is Saint Eunan, from the Gaelic Naomh Adhamhnán.
Adamnan gave sanctuary to Prince Aldfrid when the throne of Northumbria was in dispute following the death of King Oswy. When Aldfrid became king in 686, Aldamnan secured the release of all Irish prisoners taken in the conflict, and visited the monasteries of Wearmouth and Jarrow.
Attended the Council of Birr and Synod of Tara in 697 at which he helped enact the Canons of Adamnan, laws that helped protect civilian and clerical populations in areas at war, prohibiting the murder or enslavement of non-combatant women and children.
