"Werwolves" by Elliott O'Donnell is a detailed examination of lycanthropy, particularly the myths and beliefs surrounding werewolves, written in the early 20th century. The book explores the origins, classifications, and cultural significance of werewolves throughout various regions, drawing from historical accounts and folklore. It presents a blend of anthropological discourse and supernatural elements that aim to dissect the concept of metamorphosis from human to wolf. The opening portion delves into the definition of a werwolf, highlighting the complexity and various interpretations of the phenomenon across cultures and times. It discusses the linguistic roots of the term, the universal belief in lycanthropy, and contrasts differing views—ranging from skepticism about their existence to a belief in their supernatural origins. The narrative further explores how these beliefs are fueled by delusions and societal fears, while also hinting at the existence of actual anomalies that could be classified as werewolves, thus setting the stage for a thorough exploration of lycanthropic mythology and its implications in human culture.
