Note Back to Main Text — Chapter II · PRE-COLUMBIAN VOYAGES.

Now the older version, written at the beginning of the fourteenth century, gives an account of things which happened three centuries before it was written. A cautious scholar will, as a rule, be slow to consider any historical narrative as quite satisfactory authority, even when it contains no improbable statements, Presumption against sources not contemporary. unless it is nearly contemporary with the events which it records. Such was the rule laid down by the late Sir George Cornewall Lewis, and it is a very good rule; the proper application of it has disencumbered history of much rubbish. At the same time, like all rules, it should be used with judicious caution and not allowed to run away with us. As applied by Lewis to Roman history it would have swept away in one great cataclysm not only kings and decemvirs, but Brennus and his Gauls to boot, and left us with nothing to swear by until the invasion of Pyrrhus.[242] Subsequent research has shown that this was going altogether too far. The mere fact of distance in time between a document and the events which it records is only negative testimony against its value, for it may be a faithful transcript of some earlier document or documents since lost. It is so difficult to prove a negative that the mere lapse of time simply raises a presumption the weight of which should be estimated by a careful survey of all the probabilities in the case. Among the many Icelandic vellums that are known to have perished[243] there may well have been earlier copies of Eric the Red's Saga.
