“An atmosphere of magic and mystery surrounds the Tuatha Dé…We read that they first came to Ireland in obscure clouds, landing on a mountain the west of the country, and that they caused an eclipse of the sun that lasted for three days.” Dáithí Ó hÓgáin
The Tuatha Dé Dannan, Ireland’s indigenous spiritual ancestors, arrived on airships through the mists and clouds on Beltaine. The literature is clear and consistent about this. They arrived between 3,000 and 5,000 years ago, the literature is wildly inconsistent about this.
Could Benbulben be the ‘mountain in the west of the country’? Spend any time in this area and it seems likely. Very likely.
