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.
[14] Gustav Freytag, Bilder aus neuer zeit, Leipzig, 1904, p. 275 fol., speaking of the Polish borderlands, says: “Noch lebte das Landvolk in ohnmächtigem Kampf mit den Heerden der Wölfe, wenig Dörfer, welchen nicht in jedem Winter Menschen und Thiere decimirt wurden,” and in the same note 2, pp. 275-6:—“Als 1815 die gegenwärtige Provinz Posen an Preussen zurückfiel, waren auch dort die Wölfe eine Landplage. Nach Angaben der Posener Provinzialblätter wurden im Regierungsbezirk Posen vom 1. Sept. 1815 his Ende Februar 1816, 41 Wölfe erlegt, noch im Jahre 1819 im Kreise Wongrowitz 16 Kinder und 3 Erwachsene von Wölfen gefressen.”
