accepted uncritically in the related disciplines of archaeology and linguistics." Dál Riata and the territory of the neighbouring Picts merged to form the Kingdom of Alba, and Goidelic language and Gaelic culture became dominant there. The country came to be called Scotland, after the Roman name for the Gaels: Scoti. The Isle of Man and the Manx people also came under massive Gaelic influence in their history. Irish missionaries such as Saint Columba brought Christianity to Pictish Scotland. The Irishmen of this time were also "aware of the cultural unity of Europe", and it was the 6th-century Irish monk Columbanus who is regarded as "one of the fathers of Europe". Another Irish saint, Aidan of Lindisfarne, has been proposed as a possible patron saint of the United Kingdom, while Saints Kilian and Vergilius became the patron saints of Würzburg in Germany and Salzburg in Austria, respectively. Irish missionaries founded monasteries outside Ireland, such as Iona Abbey, the Abbey of St Gall in Switzerland, and Bobbio Abbey in Italy. Common to both the monastic and the secular bardic schools were Irish and Latin. With Latin, the early Irish scholars "show almost a like familiarity that they do with their own Gaelic". There is evidence also that Hebrew and Greek were studied, the latter probably being taught at Iona. Since the time of Charlemagne, Irish scholars had a considerable presence in the Frankish court, where they were renowned for their learning. The most significant Irish intellectual of the early monastic period was the 9th century Johannes Scotus Eriugena, an outstanding philosopher in terms of originality. He was the earliest of the founders of scholasticism, the dominant school of medieval philosophy. He had considerable familiarity with the Greek language, and translated many works into Latin, affording access to the Cappadocian Fathers and the Greek theological tradition, previously almost unknown in the Latin West. The influx of Viking raiders and traders in the 9th and 10th centuries resulted in the founding of many of Ireland's most important towns, including Cork, Dublin, Limerick, and Waterford (earlier Gaelic settlements on these sites did not approach the urban nature of the subsequent Norse trading ports). The Vikings left little impact on Ireland other than towns and certain words added to the Irish language, but many Irish taken as slaves inter-married with the Scandinavians, hence forming a close link with the Icelandic people.
