Tír na nÓg

[2] In Scottish Gaelic it is spelt Tìr nan Òg[3] [ˌtʲʰiːɾʲ nən̪ˠ ˈɔːk] and in Manx, Cheer nyn Aeg.

[4] Tír na nÓg is depicted as an island paradise and supernatural realm of everlasting youth, beauty, health, abundance and joy.

They reach it by entering ancient burial mounds or caves, by journeying through a mist, by going under water, or by travelling across the sea for three days on an enchanted boat or Manannán's horse.

It is the golden path made by the sun on the ocean and to travel, "far over the green meadows of the waters where the horses of Lir have their pastures."

In the tale, Oisín a member of the mythical irish warrior giants called Na Finna and Niamh (a woman of the Otherworld) fall in love.

The Druid then tells the king's daughter that she will get her own head back if she marries a son of Fionn mac Cumhaill.

[7] A grey-haired warrior visits King Cormac mac Airt carrying a silver branch with three golden apples that creates a soothing music.

The warrior, later revealed to be Manannán mac Lir, is described as wearing a purple fringed mantle, a golden ribbed shirt, and white bronze shoes or sandals.

The other fortress consists of four silver houses thatched in white bird's wings with a bronze wall surrounding it.

When Cormac enters the palace, he meets a couple – the warrior who has stolen his wife and a beautiful yellow-haired woman wearing a golden helmet, whose feet are being warmed or washed without anyone else being present.

The woman in the gold helmet then tells her story, saying that she has seven cows and seven sheep, and that the milk and wool they produce is enough for all the people in the Land of Promise.

Then the warrior places an enchanted cup of intricate and unusual workmanship and tells Cormac that when three falsehoods are spoken it will break into three pieces and then when three truths are told, it can mend itself whole.

Finn leads the Fianna to Ben-Edair, where the Tuatha Dé Danann made a solemn oath to the Gaels that if they are ever in a time of need to leave Ireland, ships will be provided.

There, they encounter two heroic brothers, who offer to serve Finn for a year and create a fleet of ships for transporting the Fianna across the sea.

Finn and the remaining Fianna travel for three days until they spot an island with a sheer cliff and cylindrical rock perched atop it, where they pick up the Gilla's track.

Dermot is then selected to scale the cliff (more slippery than an eel) because of his cowardly behavior and because he was raised on the Isle of Promise by Manannán and also taught by the Dagda's son Angus Og.

Once on the island, Dermot encounters a vast tract of dense forest where he is surrounded by the melodious sound of streams, wind, birds, and bees.

The water is pure, so Dermot stoops to drink it, and no sooner does he do so then folderol enters his head and a loud rumbling noise approaches him.

He fights fiercely until his assailants flee further into the city and out into the forest, leaving Dermot broken in a pool of his own blood.

A captain from his company explains that he has a magic branch that when waved releases beautiful music that will put people to sleep and promises to retrieve the King's daughter.

Conán declares he wants fourteen women and Abartach's own wife to ride his horse back to Ireland.

[18] Comparative mythologist Alexander Haggerty Krappe suggested that the "Gilla" character, a "horrible giant" who owned a demonic horse, was the ruler of the Otherworld realm of Tir fa Thuinn and was the "Celtic" Hades.
