Around the world and throughout our entire written history, humanity has believed that the dead can return to the land of the living, even if only for a short time. Through ancient texts and archaeological research, we can trace how people long ago understood hauntings, feared the unburied, and tried to keep the dead at rest. In this Halloween special, discover just a few of the stories of ghosts, revenants, vampires, and other restless dead from ancient to medieval sources. From the oldest texts in the world in Ancient Mesopotamia that speak of the ghosts that walked among the living, to the first Classical story to identify necromancy in Ancient Greece, to the Norse sagas of heroes defeating terrifyingly strong draugr, and the origins of vampires in Slavic lore. Explore archaeological discoveries of graves referred to as "deviant" or "anti-vampire" burials from Greek and Slavic cemeteries where the dead were physically stopped from rising again. These ancient tales of the dead also reveal what the living feared, what they valued, and how they coped with loss.
