Nothing can be clearer, however, from a survey of the whole subject, than that these pre-Columbian voyages were quite barren of results of historic importance. In point of colonization they produced the two ill-fated settlements on the Greenland coast, and nothing more. Otherwise they made no real addition to the stock of geographical knowledge, they wrought no effect whatever upon the European mind outside of Scandinavia, and even in Iceland itself the mention of coasts beyond Greenland awakened no definite ideas, and, except for a brief season, excited no interest. The Zeno narrative indicates that the Vinland voyages had practically lapsed from memory before the end of the fourteenth century.[308] Scholars familiar with saga literature of course knew the story; it was just at this time that Jon Thordharson wrote out the version of it which is preserved in the Flateyar-bok. But by the general public it must have been forgotten, or else the Fisherman's tale of Estotiland and Drogio would surely have awakened reminiscences of Markland and Vinland, and some traces of this would have appeared in Antonio's narrative or upon his map. The principal naval officer of the Faeroes, and personal friend of the sovereign, after dwelling several years among these Northmen, whose intercourse with their brethren in Iceland was frequent, apparently knew nothing of Leif or Thorfinn, or the mere names of the coasts which they had visited. Nothing had been accomplished by those voyages which could properly be called a contribution to geographical knowledge. To speak of them as constituting, in any legitimate sense of the phrase, a Discovery of America is simply absurd. Except for Greenland, which was supposed to be a part of the European world, America remained as much undiscovered after the eleventh century as before. In the midsummer of 1492 it needed to be discovered as much as if Leif Ericsson or the whole race of Northmen had never existed.
