Barrow-wight Barrow-wights are wraith-like creatures in J. R. R. Tolkien's world of Middle-earth, based on Old Norse beliefs such as Draugr or vǣttr (wights). "Barrow" refers to the burial mounds they inhabited and "wight" is a Middle English word for "living being" or "creature", especially "human being". It does not necessarily mean "spirit" or "ghost"; it is cognate to modern German "Wicht", meaning small mythical creatures (also "Wichtelmännchen"). Tolkien borrowed this concept from Norse mythology, see e.g. "Waking of Angantyr" and "Hrómundar saga Gripssonar". The name "Barrow-wight" itself was first recorded in 1869 in the Eiríkr Magnússon and William Morris translation of "Grettis saga", which features a fight with such a creature. In Norway, farmers of the 19th century were still concerned about "vetter" (wights) around old viking barrows, when these were first excavated.
