As to the American Indians, see Ethnological Report for 1880-81, p. 83, “From their close relations with wild animals Indians’ stories of transformations into beasts and beasts into men are numerous and interesting.... In times of peace, during the long winter evenings, some famous storyteller told of those days in the past when men and animals could transform themselves at will and hold converse with one another.”
Jacob Grimm, Teutonic Mythology, Bell & Sons, 1883, II. 668 says no metamorphosis occurs more frequently in Germanic antiquities than that of men into werewolves. Thus Fenrisûlfr, a son of Loki, makes his appearance in wolf’s shape among the gods.
Encyc. Brit. XV. 89 fol., under the heading Lycanthropy, states:—A belief firmly rooted among all savages is that men are in certain circumstances transformed temporarily or permanently into wolves and other inferior animals. In Europe the transformation into a wolf is by far more prominent and frequent (amongst Greeks, Russians, English, Germans, French, Scandinavians). Belief in metamorphosis into the animal most prominent in any locality itself acquires a special prominence. Thus the were-wolf prevails in Europe, also in England, Wales, Ireland; and in S. France, the Netherlands, Germany, Lithuania, Bulgaria, Servia, Bohemia, Poland, Russia, he can hardly be pronounced extinct now (see note [12]). In Denmark, Sweden, Norway and Iceland the bear competes with the wolf for pre-eminence. In Persia the bear is supreme; in Japan the fox; in India the serpent vies with the tiger (contrary to Mogk in Paul’s Grd., III. 272, who says:—“Nur Griechen, Römer, Kelten, Germanen, Slaven unter den indogermanischen Völkern kennen den Werwolf, den Indern und Iraniern ist er unbekannt.” Compare notes 6 and 9, Hertz, p. 133); in Abyssinia and Borneo the hyena with the lion; in E. Africa the lion with the alligator; in W. Africa the leopard is perhaps most frequently the form assumed by man; among the Abipones the tiger, among the Arawaks the jaguar, etc.
In Brockhaus’ Konversations-Lexikon, for the Middle Ages the werewolf belief is ascribed to all Slavic, Keltic, Germanic and Romanic peoples; found to-day especially in Volhynia and White Russia.
Paul, Grundriss, III. 272:—Bei den Angelsachsen lässt sich der Werwolf im 11. Jahrh. nachweisen: Knut befahl den Priestern, ihre Herden vor dem werewulf zu schirmen.... Das älteste Zeugnis auf deutschem Gebiete vom Werwolf ist vom Burchard v. Worms (11 century).
[11] Encyc. Brit. XV. 89 fol.:—There can nowhere be a living belief in contemporary metamorphosis into any animal which has ceased to exist in the particular locality. Belief in metamorphosis into the animal most prominent in any locality itself acquires a special prominence. (See note [12].) In none of these cases however is the power of transformation limited exclusively to the prominent and dominant animal.
[12] Encyc. Brit. XXIV. 628 fol. under Wolf:—The wolf is found in nearly the whole of Europe and Asia, North America from Greenland to Mexico, the Indian peninsula, but not in Ceylon, Burmah or Siam; and not in South America or Africa, in the two latter jackals instead.
Meyer’s Kleines konversations-lexikon:—Der wolf “ist häufig in Ost- und Nordeuropa, Mittel- und Nordasien, Nordamerika, seltener in Frankreich und Belgien, den Herden gefährlich, besonders in Russland.” Encyc. Brit., XXIV under Wolf:—In northern countries the wolf is generally larger and more powerful than in the southern portion of its range. Its habits are similar everywhere. It has from time immemorial been known to man in all the countries it inhabits as the devastator of his flocks of sheep. It has speed and remarkable endurance. They usually assemble in troops or packs, except in summer, and by their combined and persevering efforts are able to overpower and kill even such great animals as the American bison. Children and even grown people are not infrequently attacked by them when pressed for hunger. The ferocity of the wolf in the wild state is proverbial. Even when tamed, they can rarely be trusted by strangers.
