Dozmary Pool is a small lake in the Bodmin Moor in Cornwall, England, associated with the Devil. According to lore, the Devil sentenced JAN TREGEAGLE to bail out Dozmary Pool with a limpet shell, a task he could never complete. Similar punishments by the Devil are other tasks that can never be finished. Dozmary Pool also is associated with King Arthur and is one of the candidate lakes into which the dying Arthur ordered Belvedere to cast his magical sword, Excalibur. A hand arose from the lake to seize the sword and return it to the Lady of the Lake, a Fairy. The pool is haunted by mysterious lights and the ghosts of men and horses said to have drowned in it, perhaps after losing their way at night across the treacherous moor.
