This horse-like horror of Scottish folklore emerges from the sea bringing death and disease. On land this gruesome creature takes the form of a fleshless horse with a single glowing red eye and an equally fleshless human torso fused to its back. With origins in Orcadian folklore this demonic creature was blamed for plagues, drought, and death in equal measure. This episode explores how the history of the Orkney Islands, the influence of Norse mythology, a real equine disease, and the kelp trade crafted a terrifying, skinless monster. (thetvdb.com)
