Freedom from a fairy ring often requires outside intervention. A tactic from early 20th-century Wales is to cast wild marjoram and thyme into the circle and befuddle the fairies; another asks the rescuer to touch the victim with iron. Other stories require that the enchanted victim simply be plucked out by someone on the outside, although even this can be difficult: A farmer in a tale from the Llangollen region has to tie a rope around himself and enlist four men to pull him from the circle as he goes in to save his daughter. Other folk methods rely on Christian faith to break the enchantment: a stick from a rowan tree (thought to be the wood from which the cross of Jesus Christ was built) can break the curse, as can a simple phrase such as "what, in Heaven's name", as in a 19th-century tale from Carmarthenshire. A common element to these recoveries is that the rescuer must wait a year and a day from when the victim entered the ring.
