The Dagda's Stone (also called The Dagda's Dick), a wild phallic standing stone on the south flank of the Bricklieve Mountains of Sligo, not far from the Carrowkeel-Keashcorran passage-tombs, that overlooks a wedge-tomb and a glacial erratic rocking-stone known as "The Stirring Rock" -- the scene of Lughnasadh fertility-festivities on "Bilberry Sunday" up to the beginning of the twentieth century.
