Say your prayers! An ancient "cursing stone" used by Christian pilgrims to curse their enemies has just been found in the island of Canna, Scotland:
The round stone with an early Christian cross engraved on it, also known as a “bullaun” stone, is believed to be the first of its type to be found in Scotland, and was discovered by chance in an old graveyard on the island.
More commonly found in Ireland, the stones were used by ancient Christian pilgrims, who would turn them either while praying or when laying a curse, and were often to be found on sacred pilgrim routes. Traditionally, the pilgrim would turn the stone clockwise, wearing a depression or hole in a bigger “socket” stone underneath.
