The word werwolf (werewolf) is derived from the Anglo-Saxon wer (man) and wulf (wolf). There is scarcely a country in the world in which belief in werewolves, or in some other form of were-animals, has not existed. However, attempts to unravel the real phenomena remain very scarce. In Werwolves a lot of historical werewolf-cases are described which took place in several parts of Europe (France, British Isles, Germany, Austria-Hungaria & Balkan, Spain, Belgium and the Netherlands, Russia and the Scandinavian countries). Whereas in some regions the werewolf is considered wholly physical, in others it is looked upon as partly, if not entirely, astral or etheric. There is also an overlap with the Ghoul and Vampire.
