Adomnán

Adomnán or Adamnán of Iona (Latin: Adamnanus, Adomnanus; c. 624 – 704), also known as Eunan (YOO-nən; from Irish Naomh Ádhamhnán), was an abbot of Iona Abbey (r. 679–704), hagiographer, statesman, canon jurist, and saint. He was the author of the Life of Columba (Latin: Vita Columbae), 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.
