London: An ancient stone that was discovered by chance on the Isle of Canna is Scotland’s first known example of a bullaun “cursing stone”, according to experts.
Dating from about 800 AD, the stones are associated with early Christian crosses - of which there is one on the isle.
It was found in an old graveyard by a National Trust for Scotland (NTS) farm manager.
The stone about 25cm in diameter and engraved with an early Christian cross fits exactly into a large rectangular stone with a worn hole, which was located at the base of the Canna cross.
NTS manager of Canna, Stewart Connor, said the importance of the stone became clear after he was notified of the discovery.
