If legends and even many eyewitness accounts are to be believed, since ancient times we have shared our planet with various "man-beasts"—monsters that are more or less in our image. From A to Z—from the Abominable Snowman to Zombie slaves—these beings have managed either to terrify us or at least to excite our imaginations. Does the enduring fascination in movies and literature with vampires and werewolves have any basis in reality? Does Bigfoot—ostensibly our beastly relative from the past—really exist as an endangered species of the Pacific Northwest and elsewhere (including variant forms such as the Himalayan Yeti or the Australian Yowie)? Are extraterrestrials really abducting people to create alien hybrids or conversely to impart messages of hope for our fragile planet? Are they real creatures or only expressions of our very human hopes and fears? The author explores the historical, geographical, and cultural reaches of various "manimals" and other humanoid entities—among them such monster men as Gigantopithecus and Neanderthals; hairy man-beasts like Sasquatch and the elusive de Loys’ Ape; supernatural beings, including werewolves, vampires, and devil men; and supposedly spaceship-borne entities like Mothman and the Roswell humanoids. This book takes the reader on expeditions into wilderness areas, explores historical contexts, and brings folkloric and iconographic evidence to bear on a category of mysteries as old as humanity.
