Fairy rings are the subject of worldwide folklore—particularly in Western Europe. Thought to be the result of elves or fairies dancing in the grass, straying into a fairy ring was often seen as dangerous. It could bring on disease, bad luck, or put one at risk of being captured and enslaved within the fairy realm. On the lighter side, the dew from the grass of a fairy ring was prized as a cosmetic skin treatment, and used as an ingredient for love potions. In some cultures, building a home within a fairy ring would bring good luck to the family. In other cultures, it was believed that fairies buried their treasure within the fairy ring itself.
So, next time you see a faerie ring, will you stray inside, or give a wide berth?
