Story Summary
Discover the legend of Oisín in Tír na nÓg, the Celtic hero who journeyed to the Land of Youth with Niamh, only to face the tragic cost of returning home.
Oisín, the great poet-warrior of the Fianna and son of Fionn mac Cumhaill, was hunting near Lough Leane when a beautiful woman named Niamh of the Golden Hair appeared on a white steed. She invited Oisín to Tír na nÓg, the Land of Youth, where no one grows old or suffers pain. Entranced by her beauty, Oisín mounted the horse and crossed the sea to the magical realm. There, they lived in bliss for what seemed like three years, married and happy. However, a deep longing for his father and comrades eventually filled Oisín's heart. Niamh reluctantly agreed to let him visit Ireland, giving him her magical white horse but warning him of one absolute rule: his feet must never touch the soil of Ireland. Upon his return, Oisín was shocked to find three hundred years had passed; his friends were legends of the past and the world had changed. Seeing some men struggling to move a massive stone, Oisín leaned down to help. His saddle girth snapped, and as his feet touched the Irish earth, the magic of Tír na nÓg vanished. In an instant, the golden youth withered into a blind, frail old man, unable to return to the land of eternal youth or the world he once knew.
