(born circa 521, Tyrconnell—died June 8/9, 597, Iona; feast day June 9) Irish abbot and missionary. A member of the warrior aristocracy, he was excommunicated for his part in a bloody battle. Exiled, he set out to do penance as a missionary. He founded two famous monasteries in Ireland before taking 12 disciples to the Scottish island of Iona (circa 563), where they built a church and monastery that served as a base for the conversion of the Scottish Picts, and thereby Scotland, to Christianity.

In early Christian Ireland the druidic tradition collapsed, with the spread of the new Christian faith. The study of Latin learning and Christian theology in monasteries flourished. Columba became a pupil at the monastic school at Clonard Abbey, situated on the River Boyne in modern County Meath. During the sixth century, some of the most significant names in the history of Irish christianity studied at the Clonard monastery. It is said that the average number of scholars under instruction at Clonard was 3,000. Twelve students who studied under St. Finian became known as the Twelve Apostles of Ireland, Columba was one of these. He became a monk and was ordained as a priest.
Tradition asserts that, sometime around 560, he became involved in a quarrel with Saint Finnian of Moville over a psalter. Columba copied the manuscript at the scriptorium under Saint Finnian, intending to keep the copy. Saint Finnian disputed his right to keep the copy. The dispute eventually led to the pitched Battle of Cúl Dreimhne in 561, during which many men were killed. Columba's copy of the psalter has been traditionally associated with the Cathach of St. Columba. A synod of clerics and scholars threatened to excommunicate him for these deaths, but St. Brendan of Birr spoke on his behalf with the result that he was allowed to go into exile instead. Columba suggested that he would work as a missionary in Scotland to help convert as many people as had been killed in the battle. He exiled himself from Ireland, to return only once again, several years later.
Several islands are named after Columba in Scotland - including "Ì Chaluim Chille" (one of the Scottish Gaelic names of Iona), Inchcolm and Eilean Chaluim Chille
The main source of information about Columba's life is the Vita Columbae by Adomnán (also known as Eunan), the ninth Abbot of Iona, who died in 704. Both the Vita Columbae and Bede record Columba's visit to Bridei. Whereas Adomnán just tells us that Columba visited Bridei, Bede relates a later, perhaps Pictish tradition, whereby the saint actually converts the Pictish king. Another early source is a poem in praise of Columba, most probably commissioned by Columba's kinsman, the king of the Ui Neill clan. It was almost certainly written within three or four years of Columba's death and is the earliest vernacular poem in European history. It consists of 25 stanzas of four verses of seven syllables each.
The earliest recorded example of the name Arthur in a document from Great Britain occurs, as Arturius, in Adomnan's vita. There it occurs as the name of a prince among the Scots, the son of Áedán mac Gabráin, king of Dál Riata from AD 574, far from the legendary King Arthur's familiar haunts in the southwest.
The vita of Columba is also the source of the first known reference to a Loch Ness Monster. According to Adomnan, Columba came across a group of Picts who were burying a "poor little man who had been killed by the monster, and saved a swimmer with the sign of the Cross and the imprecation "You will go no further", at which the beast fled terrified, to the amazement of the assembled Picts who glorified Columba's God. Whether or not this incident is true, Adomnan's text specifically states that the monster was swimming in the River Ness -- the river flowing from the loch -- rather than in Loch Ness itself.
Through the reputation of its venerable founder and its position as a major European centre of learning, Columba's Iona became a place of pilgrimage. A network of Celtic high crosses marking processional routes developed around his shrine at Iona.
Columba is historically revered as a warrior saint, and was often invoked for victory in battle. His relics were finally removed in 849 and divided between Alba and Ireland. Relics of Columba were carried before Scottish armies in the reliquary made at Iona in the mid-8th century, called the Brecbennoch. Legend has it that the Brecbennoch, was carried to Bannockburn by the vastly outnumbered Scots army and the intercession to the Saint helped them to victory. It is widely thought that the Monymusk Reliquary is this object. O Columba spes Scotorum... "O Columba, hope of the Scots" begins a 13th century prayer in the Antiphoner of Inchcolm, the "Iona of the East".
