The names of the Irish Elysium are sometimes of a general character--Mag Mór, "the Great Plain"; Mag Mell, "the Pleasant Plain"; Tír n'Aill, "the Other-world"; Tir na m-Beo, "the Land of the Living"; Tír na n-Og, "the Land of Youth"; and Tír Tairngiri, "the Land of Promise"--possibly of Christian origin. Local names are Tír fa Tonn, "Land under Waves"; I-Bresail and the Land of Falga, names of the island Elysium. The last denotes the Isle of Man as Elysium, and it may have been so regarded by Goidels in Britain at an early time.[1231] To this period may belong the tales of Cúchulainn's raid on Falga, carried at a later time to Ireland. Tír Tairngiri is also identified with the Isle of Man.[1232] A brief résumé of the principal Elysium tales is necessary as a preliminary to a discussion of the problems which they involve, though it can give but little idea of the beauty and romanticism of the tales themselves. These, if not actually composed in pagan times, are based upon story-germs current before the coming of Christianity to Ireland. 1. _The síd Elysium._--In the story of Etain, when Mider discovered her in her rebirth, he described the land whither he would carry her, its music and its fair people, its warm streams, its choice mead and wine. There is eternal youth, and love is blameless. It is within Mider's _síd_, and Etain accompanies him there. In the sequel King Eochaid's Druid discovers the _síd_, which is captured by the king, who then regains Etain.[1233] Other tales refer to the _síd_ in similar terms, and describe its treasures, its food and drink better than those of earth. It is in most respects similar to the island Elysium, save that it is localised on earth.
