A bullaun (Irish: bullán; from a word cognate with "bowl" and French bol) is the term used for the depression in a stone which is often water filled. Natural rounded boulders or pebbles may sit in the bullaun. The size of the bullaun is highly variable and these hemispherical cups hollowed out of a rock may come as singles or multiples with the same rock. Local folklore often attaches religious or magical significance to bullaun stones, such as the belief that the rainwater collecting in a stone's hollow has healing properties. Ritual use of some bullaun stones continued well into the Christian period and many are found in association with early churches, such as the 'Deer' Stone at Glendalough, County Wicklow. The example at St Brigit's Stone County Cavan still has its 'cure' or 'curse' stones. These would be used by turning them whilst praying for or cursing somebody. In May 2012 the first cursing stone to be found in Scotland was discovered on Canna. It has been dated to circa 800.
