A Who's Who of World Mythology : Alatuir

The alatuir was a magic stone of Slavonic myth which could be found on the sacred paradise island of Bouyan. A river flowed from beneath it, the waters of which would heal all wounds. The island of Bouyan and the alatuir resembles Falias, the City of the north in Celtic and the Stone of Destiny.

Later the alatuir became a stone at the cross roads which warned heroes of impending danger, and later still, it was said to be the stone one which the Cross stood.
