Few elements of the Celtic imagination have proven as enduring or as evocative as the Otherworld, the parallel realm that exists alongside our own, peopled by the gods, by the ancestors, and by the spirits of the dead, and accessible to the living through caves, lakes, mounds, and other special places. To explore the Celtic Otherworld of Tír na nÓg is to enter the heart of the Celtic cosmology and the Otherworld, and to follow one of the most distinctive and most beautiful of all the Celtic literary traditions, the tradition of the journey to the land of the young, of eternal youth, and of unending abundance. As part of the broader world of Celtic religion, mythology, and spirituality, the Otherworld was a central feature of the Celtic religious imagination, and its influence can still be felt in the literature and folklore of the modern Celtic-speaking regions.
The Concept of the Celtic Otherworld
The Celtic Otherworld was not simply a place of the dead in the Christian sense. It was a place where the rules of ordinary life did not apply, where time moved differently, where the inhabitants were often the gods themselves or the ancestors of the living, and where the heroes of myth and legend might visit and return. The Otherworld was conceived as existing in a parallel relationship to the world of the living, sometimes overlapping with it, sometimes hidden within it, and sometimes accessible only through particular places and at particular times. The seasonal openings of the Otherworld, particularly at Samhain and Bealtaine, were times when the boundary between the worlds was thinnest, and when the living could most easily cross over to the land of the dead.
The location of the Otherworld varied in the Celtic tradition. Sometimes it was located in the west, beyond the sea, in keeping with the general Celtic association of the west with death and the Otherworld. Sometimes it was located beneath the earth, in the sídhe or fairy mounds that dotted the Irish landscape, and the descriptions of the underground cities of the Tuatha Dé Danann preserve the older tradition. Sometimes it was located beneath the sea, as in the immrama or voyage tales of the Irish tradition, in which the hero sails across the western ocean to reach the Otherworld. Sometimes it was located on a distant island, often in the west, and the descriptions of the Hy-Brasil and other mythical islands preserve the older tradition. The flexibility of the location distinctive features of the Celtic Otherworld, and it suggests that the Celts conceived of the Otherworld as a parallel reality that could be accessed through many different gates.
Tír na nÓg in the Irish Tradition
Tír na nÓg, the “Land of the Young” or “Land of the Ever-Young,” is the most famous of the Irish names for the Otherworld, and it is the name that has come to be used, in the popular imagination, for the entire Celtic Otherworld. The name appears in the Tochmarc Étaíne (The Wooing of Étaíne), a tale of the Mythological cycle in which the hero Midir carries the beautiful Étaíne away to his dwelling in the sídhe of Bri Léith, and in a number of other tales of the medieval Irish tradition. The characteristic feature of Tír na nÓg, as described in the medieval sources, is that it is a place of eternal youth, of abundant harvest, of unending feasting, and of surpassing beauty. The inhabitants of the land, often identified as the Tuatha Dé Danann, do not age, do not sicken, and do not die, and they live in a state of perpetual happiness.
The most famous description of Tír na nÓg is in the Acallam na Senórach (The Colloquy of the Ancients), a long prose tale of the late twelfth or early thirteenth century, in which Oisín, the legendary warrior and poet of the Fenian cycle, encounters Saint Patrick and his followers after returning from a long absence. Oisín, who has been away in Tír na nÓg for what seems to him like a few years, finds that, in the world of the living, three hundred years have passed, and that all his comrades are long dead. The story of Oisín in Tír na nÓg, with its theme of the hero who returns from the Otherworld to find that everything has changed, is one of the most poignant narratives of medieval Irish literature, and it has been studied as retellings and adaptations in the centuries since.
The Voyage of Bran mac Febail
The Immram Brain (The Voyage of Bran), one of the great voyage tales of the medieval Irish tradition, is another central text for the understanding of Tír na nÓg. The tale tells of Bran mac Febail, a prince of the Tuatha Dé Danann, who hears a mysterious music one evening and falls into a trance. When he wakes, a magical branch of silver with white blossoms has appeared at his door, and a woman from the Otherworld sings to him of a far-off land across the sea, a land of perpetual music, of eternal youth, and of unending beauty. Bran sets out on a voyage to find the land, and after many adventures he and his companions reach the Otherworld, where they are welcomed by Manannán mac Lir, the sea god of the Irish tradition, and by the woman who had sung to him.
The voyage of Bran, like the voyage of Oisín, contains the characteristic theme of the Otherworld journey: the hero crosses a boundary, often a body of water, into a realm where time moves differently, and he spends what seems to him like a short time in the Otherworld before returning to the world of the living to find that many years have passed. The motif, which has been called the Otherworld motif by the folklorist Antti Aarne and the Svenning Larsen by later scholars, is one of the most widespread in world folklore, and its presence in the Celtic tradition is among the most vivid and most fully developed of any in European literature. The parallels with the immrama of the early Christian monastic tradition, in which Irish monks sailed across the Atlantic in search of the terra repromissionis or promised land, are striking, and they suggest that the older pagan tradition of the Otherworld voyage was preserved in transformed form in the Christian imagination.
Annwn in the Welsh Tradition
The Welsh counterpart of Tír na nÓg, Annwn or Annwfn, is the name of the Otherworld in the medieval Welsh tradition. Annwn is mentioned in the Mabinogion and in the works of the medieval Welsh bards, including the famous poem of Taliesin, the Preiddeu Annwfn (The Spoils of Annwn), which describes a journey by Arthur and his warriors to the otherworldly realm in search of a magical cauldron. The cauldron, which is associated with the Pair Dadeni or Cauldron of Rebirth, has obvious connections with the Coire Anni or cauldron of plenty of the Irish Dagda, and the Welsh tradition, like the Irish, places great emphasis on the magical and regenerative properties of the Otherworld.
The Welsh tradition of Annwn is somewhat darker than the Irish tradition of Tír na nÓg. While the Irish Otherworld is often a place of unalloyed beauty and happiness, the Welsh Annwn is sometimes a place of danger, of imprisonment, and of the threat of being trapped in the Otherworld and never returning. The tale of Pwyll and Rhiannon in the Mabinogion, in which the lord of Dyfed marries a mysterious woman from Annwn, and the tale of Manawydan fab Llŷr, in which the same region is subjected to a magical enchantment that binds its inhabitants, are examples of the darker side of the Welsh Otherworld. The contrast between the two traditions, while it should not be exaggerated, reflects a different emphasis in the Welsh and Irish conceptions of the Otherworld.
The Landscape of the Otherworld
The landscape of the Celtic Otherworld, as described in the medieval sources, is one of remarkable beauty and abundance. The plains of the Otherworld, called the Mag Mell (the Plain of Joy) or the Mag Buada (the Plain of Triumph) in the Irish tradition, were described as places of unending harvest, where the fruits of the earth ripened continuously and the trees were always in fruit. The rivers of the Otherworld flowed with wine or with mead, and the trees of the Otherworld, often described as silver birches or apple trees, were always in blossom or in fruit. The music of the Otherworld, the ceol sí or fairy music of the Irish tradition, was of surpassing beauty, and the inhabitants of the land were often described as being entertained by magical musicians whose music could charm the birds from the trees.
The architecture of the Otherworld was similarly splendid. The sídhe or fairy mounds of the Irish tradition, which served as the dwellings of the Tuatha Dé Danann, were described as great palaces of silver and gold, with halls of mead and feasting, with gardens of perpetual beauty, and with all the conveniences of an aristocratic household. The cities of the Otherworld, in the Welsh tradition, were similarly splendid, and the descriptions of the cities of Annwn in the medieval Welsh poetry are some of the most vivid and most beautiful passages in all of medieval Welsh literature. The contrast between the splendor of the Otherworld and the modest conditions of ordinary life in the medieval Celtic-speaking regions striking features of the literary tradition.
The Inhabitants of the Otherworld
The inhabitants of the Celtic Otherworld were many and various. The Tuatha Dé Danann, the semi-divine race of Irish tradition, were the principal inhabitants of the Irish Otherworld, and they had retreated into the sídhe after their defeat by the Milesians, the mythological ancestors of the Irish people. The fairy folk or daoine sídhe of the later Irish and Scottish tradition, the Tywyth Teg or Fair Family of the Welsh tradition, and the Corrigan, the Lavandières, and other figures of Breton folklore are all descendants of the older inhabitants of the Otherworld. The dead, too, were inhabitants of the Otherworld, and the descriptions of the Otherworld as a place where the dead continue to live in a state of unending happiness reflect older beliefs about the afterlife that were not entirely replaced by the Christian doctrine of heaven and hell.
The literary descriptions of the inhabitants of the Otherworld often preserve older religious traditions in disguised form. The Tuatha Dé Danann, who in the medieval sources are presented as a race of magical beings who have retreated into the fairy mounds, were originally the gods of the Irish, and their description as the inhabitants of the Otherworld is a way of preserving the memory of the older religion in a form that was acceptable to the Christian authors of the medieval tales. The fairy queens and fairy kings of the later Irish and Scottish tradition, like Aine and Midir and Manannán mac Lir, are often transparently old gods in new guise, and the fairy mistress of the medieval Welsh tale of Pwyll and Rhiannon, who is the lord of Annwn, is similarly an older divine figure in a medieval literary dress.
The Journey to the Otherworld
The journey to the Celtic Otherworld, in the literary tradition, is one of the most fully developed of all the otherworld journey motifs in world literature. The journey typically begins with a call from the Otherworld, often in the form of a magical music, a beautiful woman, or a mysterious branch, that draws the hero away from his ordinary life. The hero then crosses a boundary, often a body of water, a mist, or a magical mist, and arrives in the Otherworld, where he spends a period of time that is variously described as a single night, a few days, or a year. He then returns, often with a talisman from the Otherworld, to the world of the living, where he finds that many years have passed, and that all his contemporaries are dead.
The most famous of the journey tales, beyond the tales of Oisín and Bran, include the Welsh tales of Culhwch and Olwen, in which Arthur and his warriors make a journey to the Otherworld in search of various magical objects, and Pwyll and Rhiannon, in which the lord of Dyfed encounters the Otherworld in a more personal way. The Breton lays of Marie de France, particularly Lanval and Yonec, contain similar motifs, and the ar Gwrdd of the medieval Welsh tradition, the encounter with the Otherworld woman who offers love and happiness in exchange for faithfulness, is a central theme of the medieval Welsh and Breton literary traditions. The persistence of these motifs in the literary traditions of the modern Celtic-speaking regions striking features of the Celtic contribution to European literature.
