Icelandish

Some geographical manuscripts written in the Icelandish language in the fourteenth or fifteenth century, and based in part on the statement of the Abbot Nicholas of Thingeyre, who died in 1159 A.d., according to Storm, Werlauff, and Rafn, also bear early witness to the discovery of Vinland by Leif Ericson, to Leif's Christianizing Greenland, and to the establishment of an episcopal see in Gardar.
