From The Outer Hebrides and their Legends by Otta F. Swire, 1966:
“It is said that there was a standing stone carved with a cross and known as Crois nan Cnoca Breaca on a small hill on the north boundary of Ormaclett and that it marked the spot where ‘Our Saviour of Victory’ stood and so long as Howmore Church was in we all those who came to it from the south always knelt there to pray. Martin says that the people bowed to the church from this stone which they set up at the first point from which St. Columba’s church at Howmore could be seen and so it was called ‘the bowing stone’. One wonders if both the stone and the sacredness of this part of South Uist are not much older than Christianity.”
