 In the "Life of Columba", Adamnan mentions in passing that St Martin was commemorated during Mass at Iona.In his "Ireland and Her Neighbours in the Seventh Century", Michael Richter attributes this to the mission of Palladius seen within the wider context of the mission of Germanus of Auxerre to Britain around 429.Thus, this could be the context in which the Life of St Martin was brought from Gaul to Ireland at an early date, and could explain how Columbanus was familiar with it before he ever left Ireland.
