 Aedh as patron of the "Vita" must have had some say in what underlying messages were written into the "Vita", and Muirchú's companionship with Aedh could have led him to want to help establish Armagh as an important center.Hughes also believes that Muirchú presents Patrick not only as the founder of a church in Ulster but as a missionary, who was accepted by the Ui Néill, the dominant power in Northern Ireland in Muirchú's time.That being said, in the "Vita", Muirchú confines Patrick's activities to the north-east of Ireland, and more specifically, in the second part of the "Vita", his activities are mainly confined to the province of Ulster.
