[the Arctic geography] from the Itinerium of Jacobus Cnoyen of the Hague, who makes some citations from the Gesta of Arthur of Britain; however, the greater and most important part he learned from a certain priest at the court of the king of Norway in 1364. He was descended in the fifth generation from those whom Arthur had sent to inhabit these lands, and he related that in the year 1360 a certain Minorite, an Englishman from Oxford, a mathematician, went to those islands; and leaving them, advanced still farther by magic arts and mapped out all and measured them by an astrolabe in practically the subjoined figure, as we have learned from Jacobus. The four canals there pictured he said flow with such current to the inner whirlpool, that if vessels once enter they cannot be driven back by wind." Encounters Landnámabók According to the Landnámabók, Ari Marsson discovered the land six days' sailing west of Ireland. This journey is thought to have occurred around the year 983.

Annals of Greenland The Annals of Greenland, an 11th-century Norse chronicle, says: Next to Vinland the Good and a little beyond lies Albania, which is Hvitramannaland. Thither formerly were sailings from Ireland. Irishmen and Icelanders recognized Ari, son of Mar and Thorkatla from Reykjaness, of whom no tidings have been received for a long time and who became a chieftain of the land. Saga of Eric the Red White Men's Land is also mentioned in the Saga of Eric the Red, where it is related that the inhabitants of Markland speak of it to Thorfinn Karlsefni. Now, when they sailed from Vinland, they had a southern wind, and reached Markland, and found five Skrælingar; one was a bearded man, two were women, two children. Karlsefni's people caught the children, but the others escaped and sunk down
