Abbots of Iona

Columba () or Colmcille (7 December 521 – 9 June 597 AD) was an Irish abbot and missionary evangelist credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the patron saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Catholic saint and one of the Twelve Apostles of Ireland.

Adomnán or Adamnán of Iona (; , Adomnanus; 624 – 704), also known as Eunan ( ; from ), was an abbot of Iona Abbey ( 679–704), hagiographer, statesman, canon jurist, and saint. He was the author of the Life of Columba (), probably written between 697 and 700. This biography is by far the most important surviving work written in early-medieval Scotland, and is a vital source for our knowledge of the Picts, and an insight into the life of Iona and the early-medieval Gaelic monk.
