Echtrae Láegairi
Irish title for an Old Irish narrative usually translated as the Adventure of Lóegaire. Texts are found in the Book of Leinster and the Book of Fermoy. It is distinguished from others of its type by having the mortal warrior lured away to the Otherworld in order to take sides in an otherworldly conflict.
Early one morning a mysterious warrior approaches the king of Connacht, Crimthann Cass, and his retinue while they are assembled at Énloch in Mag Aí (Co. Roscommon). The stranger identifies himself to Lóegaire mac Crimthainn, the king's son, as Fiachna mac Rétach, who has come from the otherworldly realm of
In reward for having his wife restored, Fiachna grants Lóegaire his daughter, Dér Gréine, and fifty maidens to his fifty men. The Connachtmen then stay in Mag Dá Chéo a year before returning home, having been warned by Fiachna not to dismount. They find their fellows still assembled. When the king's retainers come forth to greet Lóegaire, he tells them to stand back, saying that they have only returned to say farewell. Crimthann cries for his son not to leave, offering him the kingdom, gold, silver, steeds, and fair women. Lóegaire responds in a poem of praise of the Otherworld, its delightful music and the happiness of love. He then goes forth to the fairy mound to live with Dér Gréine in the fort of Mag Mell; and there he still is.
Kenneth Jackson edited the text under the title ‘The Adventure of Laeghaire Mac Crimthainn’, Speculum, 17 (1942), 377–89. Mag Mell and Mag Dá Chéo of the story illustrate folk motif F111.
