There is archaeological evidence of insular monasticism as early as the mid 5th century,[1] influenced by establishments in Gaul such as the monastery of Martin of Tours at Marmoutier, the abbey established by Honoratus at Lérins; the abbey of Mont-Saint-Michel; and that of Germanus at Auxerre. Many Irish monks studied at Candida Casa near Whithorn in what is now Galloway in Scotland.
