Father Seán ÓLaoire

To Gaelic Tír fo Thuinn was an advanced civilization

12,800 BCE to 600 BCE

Father Seán ÓLaoire explains that, according to Gaelic mythology, Atlantis, or Tír fo Thuinn (the Land Under the Waves), was an advanced civilization that sank under the Atlantic Ocean. Survivors of Atlantis are believed to have spread across different regions, including Ireland. One group of survivors, the Tuatha Dé Danann, arrived in Ireland and ruled for thousands of years before the arrival of the Celts around 600 BCE.


The Celts and the Tuatha Dé Danann had two great battles, with the Celts emerging victorious. Instead of a straightforward division of the land, the Celts agreed to inhabit the surface of Ireland while the Tuatha Dé Danann would inhabit the underground. The Tuatha Dé Danann then became known as the fairy folk, or the fairy fort people, in Irish folklore.

Father Seán connects these mythological events to the spread of advanced knowledge and spirituality from Atlantis. He suggests that survivors from Atlantis, who possessed advanced mental and possibly technological capabilities, sought to elevate the consciousness of the populations they encountered, who were often reduced to more primitive states due to the catastrophic events that led to the sinking of Atlantis.

Furthermore, Father Seán elaborates on how these survivors might have contributed to the formation of mystery schools and esoteric traditions in various ancient civilizations, including Egypt, through their advanced knowledge and spiritual teachings.

These mystery schools were meant to identify and train individuals who were ready for higher levels of spiritual evolution, ensuring that the transmission of this advanced wisdom continued despite the destruction of their original homeland.

Tír fo Thuinn

Also known as “the Land Under the Waves,” is a concept from Gaelic mythology, often associated with the mystical and mythical lands in Irish folklore. Here are some key points about Tír fo Thuinn:

Mythological Origins: Tír fo Thuinn is one of the many otherworldly realms in Irish mythology, which includes places like Tír na nÓg (the Land of the Ever-Young) and Mag Mell (the Plain of Delight). These realms are often depicted as paradisiacal and are inhabited by supernatural beings.

Association with Atlantis: In some interpretations, Tír fo Thuinn is equated with the concept of Atlantis. This connection suggests that Tír fo Thuinn was a highly advanced civilization that sank beneath the ocean. The survivors of this sunken land are believed to have spread their knowledge and culture to various parts of the world, including Ireland.

Tuatha Dé Danann: The Tuatha Dé Danann, a supernatural race in Irish mythology, are often linked to Tír fo Thuinn. According to legend, they arrived in Ireland from this mystical land. After being defeated by the Celts, the Tuatha Dé Danann were said to have retreated to live underground in fairy mounds, becoming the fairy folk of Irish lore.

Symbolism: Tír fo Thuinn represents a lost golden age, a place of great wisdom and magic that was destroyed or hidden beneath the waves. It symbolizes the idea of a hidden or submerged truth or knowledge that can only be accessed through spiritual means or profound transformation.
