The ethnological traces are only less shadowy. Hugo Grotius[656] contended that the people of Central America were of Scandinavian descent. Brasseur found remnants of Norse civilization in the same region.[657] Viollet le Duc[658] discovers great resemblances in the northern religious ceremonials to those described in the _Popul Vuh_. A general resemblance did not escape the notice of Humboldt. Gravier[659] is certain that the Aztec civilization is Norse.[660] Chas. Godfrey Leland claims that the old Norse spirit pervades the myths and legends of the Algonkins, and that it is impossible not to admit that there must have been at one time “extensive intercourse between the Northmen and the Algonkins;” and in proof he points out resemblances between the Eddas and the Algonkin mythology.[661] It is even stated that the Micmacs have a tradition of a people called Chenooks, who in ships visited their coast in the tenth century. The physical and geographical evidences are held to exist in the correspondences of the coast line to the descriptions of the sagas, including the phenomena of the tides[662] and the length of the summer day.[663] Laing and others, who make no question of the main fact, readily recognize the too great generality and contradictions of the descriptions to be relied upon.[664] George Bancroft, in showing his distrust, has said that the advocates of identification can no farther agree than to place Vinland anywhere from Greenland to Africa.[665] [Illustration: A MAP OF VINLAND from accounts contained in Old Northern M.S.S. by CHARLES C. RAFN NOTE.—The above map is a fac-simile of one of C. C. Rafn’s maps. Cf. the maps in Smith, Beamish, Gravier, Slafter, Preble’s _Amer. Flag_, etc. ] The earliest to go so far as to establish to a certainty[666] the sites of the sagas was Rafn, who placed them on the coast of Massachusetts and Rhode Island, wherein nearly all those have followed him who have thought it worth while to be thus particular as to headland and bay. [Illustration: DIGHTON ROCK.[667]] In applying the saga names they have, however, by no means agreed, for Krossanes is with some Point Alderton, at the entrance of Boston Harbor, and with others the Gurnet Head; the island where honey dew was found is Nantucket with Rafn, and with De Costa an insular region, Nauset, now under water near the elbow of Cape Cod;[668] the Vinland of Rafn is in Narragansett Bay, that of Dr. A. C. Hamlin is at Merry Meeting Bay on the coast of Maine,[669] and that of Horsford is north of Cape Cod,[670]—not to mention other disagreements of other disputants.
