 Muirchú was aware that his sources might not always be reliable, as he was writing fairly long after Patrick's death, but made an attempt to tell the story of Patrick's life as best he could with the available sources.The "Vita" is a hagiography, written to tell the life story of a Saint, but also including events that may have simply been added to make the Saint seem more impressive.Muirchú writes in a more fluent style than Patrick had in his works, which were notably written is what was considered bad Latin, but not as polished as Cogitosus’ Latin.
