Traditional accounts

Traditional accounts ascribe different reasons for this battle. The most famous is the story about the copying of a book belonging to Saint Finnian by Columcille - an account that first appears in the Life written by Manus O'Donnell, written nearly a thousand years after the alleged events supposedly took place, and therefore a highly unreliable source. According to O'Donnell, sometime around 560, the Irish abbot and missionary

). Columba copied the manuscript at the scriptorium under Saint Finnian, intending to keep the copy. Saint Finnian disputed his right to keep the copy. Thus, this dispute was about the ownership of the copy (whether it belonged to Saint Columba because he copied it or whether it belonged to Saint Finnian because he owned the original). King

clan against the King. The battle was claimed to have caused around 3,000 casualties. Another traditional reason given for the battle concerns the violation of sanctuary. The Annals Of Tighernach for the year 559, record the death of Curnan son of Aed, son of Eochaid Tirmcharna by

The Chronicles of Iona state that "In the second year after the battle of Cul-drebene, the forty-second year of his age, Columba sailed away from Ireland to Britain wishing to be a pilgrim for Christ." This last note rather contradicts the notion that Columba had been sent away as a punishment: he was rather fulfilling a monastic vocation.

Modern investigations

However, these later versions have been disputed by modern scholarship on several grounds, particularly as early mentions of the battle do not refer to the book incident. It may have been a dynastic battle between the Cinel Cairbre and Diarmait Mac cerbaill who had wrested the kingship at Tara from them after the death of Tuathal Maelgarb.
