For millennia, societies have told tales of their fears incarnate—otherworldly couriers of plague, death, temptation, and moral decline. The Penguin Book of Demons summons these supernatural creatures—and the humans who have hunted and been haunted by them—across cultures and continents: the daemons of ancient Greece and Rome; the giant, biblical half humans known as Nephilim who stalked the earth before the Great Flood; corrupted angels, condemned to eternity in Hell; the jinn of Islamic Arabia; the female, child-eating Gelloudes of Byzantium; the seductive incubi and succubi of northern Europe; the animal spirits of early modern China; and the cannibalistic Wendigoof Native American folklore. From demonic possession to black magic, these accounts give life to a spellbinding, skin-crawling history of the paranormal.
