They are called will-o’-the-wisps in some places, but in Friesland we know them as Nachtlampken. You may see them upon the

road at night, or hovering about the stones in a cemetery. Like the widde juvven, their preferred homes are swamps and grave

mounds, and they appear as luminous figures holding lanterns aloft. Many a fool has been drawn to their lamps, thinking to

find the treasure that the Nachtlampken are said to guard. But these fools are not rewarded with treasure or indeed any other

earthly thing. They find only a watery grave and an eternity of torment.
