 Many scholars argue that the "Vita sancti Patricii" should be seen as a piece of literature, usually falling into the category of hagiography.This is often attributed to the contrast between Patrick's own writings and Muirchú's, because there are parts that vary to a fair degree.The beginning of the "Vita" generally follows along the same lines as Patrick's accounts of his life, but after the scenes where Patrick escapes from Ireland and returns to Britain, it takes a different turn.
