Adomnán was a 7th-century Irish abbot, statesman, and scholar who served as the ninth leader of Iona Abbey. Born around 624 in what is now County Donegal, he was a relative of the monastery's founder, Columba. He is widely recognized for his significant literary contributions, including a major biography of Columba and a treatise on holy sites. As a jurist, he established legal protections for non-combatants, earning him a lasting reputation as a protector of the innocent and a key figure in early medieval Gaelic history.
