In the thirteenth century, French flourished as a literary language, and produced the "Roman de Fergus", the earliest piece of non-Celtic vernacular literature to survive from Scotland. Many other stories in the Arthurian Cycle, written in French and preserved only outside Scotland, are thought by some scholars including D. D. R. Owen, to have been written in Scotland. There is some Norse literature from areas of Scandinavian settlement, such as the Northern Isles and the Western Isles. The famous "Orkneyinga Saga" however, although it pertains to the Earldom of Orkney, was written in Iceland. In addition to French, Latin too was a literary language, with works that include the "Carmen de morte Sumerledi", a poem which exults triumphantly the victory of the citizens of Glasgow over Somairle mac Gilla Brigte and the "Inchcolm Antiphoner", a hymn in praise of St. Columba.
