This is the ordinary and best authenticated account of the discovery and settlement of Old Greenland, which rests on the credit of the great northern historian, Snorro Sturleson, judge of Iceland, who wrote in the year 1215. Yet others assert that Greenland had been known long before, and ground their assertion on letters-patent from the Emperor Lewis the Pious in 834, and a bull of Gregory IV. in 835, in which permission is given to Archbishop Ansgar to convert the Sueones, Danes, Sclavonians; and it is added, the Norwaehers, Farriers, Greenlanders, Halsingalanders, Icelanders, and Scridevinds. Even allowing both charter and bull to be genuine, it is probable that the copy which has come down to our time is interpolated, and that for Gronlandon and Islandon, we ought to read Quenlandon and Hitlandon, meaning the Finlanders and Hitlanders: Quenland being the old name of Finland, and Hitland or Hialtaland the Norwegian name of the Shetland islands. It is even not improbable that all the names in these ancient deeds after the Sueones, Danes, and Sclavonians, had been interpolated in a later period; as St Rembert, the immediate successor of Ansgar, and who wrote his life, only mentions the Sueones, Danes, and Sclavonians, together with other nations in the north; and even Adam of Bremen only mentions these three, and other neighbouring and surrounding nations. Hence the authority of St Rembert and Snorro Sturleson remains firm and unshaken, in spite of these falsified copies of the papal bull and imperial patent; and we may rest assured that Iceland was not discovered before 861, nor inhabited before 874; and that Greenland could hardly have been discovered previous to 982, or 983, and was not inhabited before 985 or 986.—Forst.
