[Footnote 216: A favourite method of determining the exact spots visited by the Northmen has been to compare their statements regarding the shape and trend of the coasts, their bays, headlands, etc., with various well-known points on the New England coast. It is a tempting method, but unfortunately treacherous, because the same general description will often apply well enough to several different places. It is like summer boarders in the country struggling to tell one another where they have been to drive,--past a school-house, down a steep hill, through some woods, and by a saw-mill, etc.] [Sidenote: "Savages" unknown to mediaeval Europeans.] [Sidenote: The natives of Vinland.] But we have not yet done with the points of verisimilitude in our story. We have now to cite two or three details that are far more striking than any as yet mentioned,--details that could never have been conjured up by the fancy of any mediaeval European. We must bear in mind that "savages," whether true savages or people in the lower status of barbarism, were practically unknown to Europeans before the fifteenth century. There were no such people in Europe or in any part of Asia or Africa visited by Europeans before the great voyages of the Portuguese. Mediaeval Europeans knew nothing whatever about people who would show surprise at the sight of an iron tool[217] or frantic terror at the voice of a bull, or who would eagerly trade off valuable property for worthless trinkets. Their imagination might be up to inventing hobgoblins and people with heads under their shoulders,[218] but it was not up to inventing such simple touches of nature as these. Bearing this in mind, let us observe that Thorfinn found the natives of Vinland eager to give valuable furs[219] in exchange for little strips of scarlet cloth to bind about their heads. When the Northmen found the cloth growing scarce they cut it into extremely narrow strips, but the desire of the natives was so great that they would still give a whole skin for the smallest strip. They wanted also to buy weapons, but Thorfinn forbade his men to sell them. One of the natives picked up an iron hatchet and cut wood with it; one after another tried and admired it; at length one tried it on a stone and broke its edge, and then they scornfully threw it down.[220] One day while they were trading, Thorfinn's bull ran out before them and bellowed, whereupon the whole company was instantly scattered in headlong flight. After this, when threatened with an attack by the natives, Thorfinn drew up his men for a fight and put the bull in front, very much as Pyrrhus used elephants--at first with success--to frighten the Romans and their horses.[221]
