One of the stories of St. Colmcille that I am most familiar with is the copyright issue over a psalter which St. Colmcille had copied from one of St. Finnian's text. Since St. Colmcille's family was somewhat powerful, they were set to defend his ownership of this psalter, even fighting a battle over it. The dispute was adjudicated in the favor of St Finnian (to each book its copy) with St. Colmcille accepting voluntary exile to Scotland (Iona) to stop the bloodshed. After visiting the beautiful lands of his clan in Donegal, I can imagine how heartbreaking such an exile would have been.
