Many folk beliefs generally paint fairy rings as dangerous places, best avoided. American writer Wirt Sikes traces these stories of people trespassing into forbidden territory and being punished for it to the tale of Psyche and Eros. In it, Psyche is forbidden to view her lover, and when she does so, her palace disappears and she is left alone. Superstition calls fairy circles sacred and warns against violating them lest the interloper (such as a farmer with a plough) anger the fairies and be cursed. In an Irish legend recorded by Wilde, a farmer builds a barn on a fairy ring despite the protests of his neighbours. He is struck senseless one night, and a local "fairy doctor" breaks the curse. The farmer says that he dreamed that he must destroy the barn. Even collecting dew from the grass or flowers of a fairy ring can bring bad luck. Destroying a fairy ring is unlucky and fruitless; superstition says it will just grow back.
