Welcome back to “This Day in Scottish History.” I’m your host, Colin MacDonald. Today, we journey back to a pivotal figure in early-medieval Scotland, a man whose impact on the spiritual and legal world continues to be felt to this day: Adomnán of Iona. He passed away on this day, September 23rd, in the year 704. More than just an abbot, Adomnán was a saint, a statesman, and a scholar whose contributions resonate across both Scotland and Ireland.

Adomnán, also known as Saint Adomnán or Eunan, was born around the year 624 into the Northern Uí Néill lineage, a powerful Gaelic dynasty in what is now County Donegal in modern-day Ireland. His connection to the region was deep, not only by blood but by faith. He is thought to have been a relative of Saint Columba, the founder of Iona Abbey, which would play such an important role in his life.

Adomnán’s early life is somewhat shrouded in mystery, as is common for figures from that time. What we do know is that he joined the Columban monastic tradition, a network of monasteries tied to Iona Abbey. He likely spent his early years at one of these monasteries in either northern Ireland or the kingdom of Dál Riata, which spanned parts of modern-day western Scotland and Ireland. He was a man of rare intellect, and his education was extensive for the period—learning that would help shape the future of both the abbey and early medieval scholarship.

In 679, Adomnán became the ninth abbot of Iona, a role that came with immense spiritual and political responsibility. Iona Abbey was one of the most important religious centers in Gaelic Christianity, and as abbot, Adomnán was both a spiritual leader and a diplomat. One of his close associates was King Aldfrith of Northumbria, with whom Adomnán shared a strong relationship. In 686, he helped negotiate the release of 60 Gaels captured during a raid by Northumbrians—a reflection of his diplomatic skill and influence.

But it wasn’t just his diplomacy that set Adomnán apart—it was his profound sense of justice. Perhaps his most lasting legacy is the Cáin Adomnáin, or “Law of Adomnán,” also known as the “Law of Innocents.” This law, enacted in 697 at the Synod of Birr, was revolutionary for its time. It sought to protect non-combatants during times of war, particularly women, children, and clergy. This early form of humanitarian law was groundbreaking in an era of frequent conflicts, and it laid the groundwork for similar protections that would emerge much later in European legal traditions.

Another one of Adomnán’s significant works was his hagiography of Saint Columba, Vita Columbae, written between 697 and 700. This biography is one of the most important surviving works from early medieval Scotland, offering an invaluable insight into the life of Columba and the early Christian communities of the time. The stories it tells not only document Columba’s miracles and influence but also provide details about the Picts, who were the dominant people in northern and eastern Scotland during this period. Through his writing, Adomnán preserved a wealth of knowledge about Iona’s history, spirituality, and daily life.

Adomnán’s influence also extended beyond the abbey walls and into the wider Christian world. He wrote another treatise, De Locis Sanctis—“On Holy Places”—a description of key Christian pilgrimage sites, including Jerusalem, Rome, and Constantinople. This work was informed by the travels of a Frankish bishop named Arculf, who had visited these holy places and later shared his experiences with Adomnán at Iona. De Locis Sanctis was not only a spiritual guide but also a testament to the far-reaching connections of the Iona monastery.

Despite these great accomplishments, Adomnán’s life wasn’t without challenges. One of his most difficult tasks was attempting to reconcile the Columban monasteries of Iona with the Roman Catholic Church over the date of Easter. While many parts of the British Isles, including Northumbria, had adopted the Roman dating of Easter following the Synod of Whitby in 664, Iona held out, continuing to observe its traditional date. Although Adomnán personally accepted the Roman calendar, he could not persuade the monks of Iona to do the same during his lifetime, leading to a rare schism within the monastery.

Adomnán’s death on September 23, 704, marked the end of an extraordinary life dedicated to faith, justice, and scholarship. His influence, however, did not end there. In both Scotland and Ireland, he is venerated as a saint, and his feast day continues to be celebrated on this date. He is a patron saint of the Roman Catholic Diocese of Raphoe in Donegal, Ireland, and many institutions, churches, and schools throughout the region bear his name.

In 727, more than two decades after his death, Adomnán’s relics were brought to Ireland to renew the Cáin Adomnáin, reaffirming the enduring significance of his legal reforms. Today, Adomnán is remembered as one of the most important figures in early medieval Scotland and Ireland, a man whose life and work shaped the spiritual and legal landscape of his time.

As we remember Saint Adomnán today, we reflect on his legacy of peace, justice, and devotion. His vision for a world where the innocent were protected from the ravages of war continues to inspire, reminding us that even in the darkest of times, there are those who strive for compassion and justice.
