<blockquote>The patron saint of media piracy, of course, is St. Columba of Iona, who borrowed a psalter from St. Finnian, sometime in the 6th century CE, made a copy, and refused to give St. Finnian the copy when he returned the original. St. Finnian demanded the copy back, St. Columba declared it was his, and they appealed to King Diarmait of Ireland, who declared "every cow its calf, every book its copy," in favor of St. Finnian. This being 6th century Ireland, it ended in Columba raising his clan in rebellion against the king, and around 3,000 men died in the Battle of Cúl Dreimhne before Columba went into voluntary exile in Scotland to avoid excommunication.
He took his copy of the psalter with him when he went, though!</blockquote>
