The medieval Celtic world produced one of the most distinctive and most extensive literary traditions of early medieval Europe, a body of work in Irish, Welsh, Breton, Cornish, and Scottish Gaelic that ranks in importance alongside the great vernacular literatures of the continent. The great Irish sagas of the Ulster cycle and the Fenian cycle, the mythological narratives of the Lebor Gabála Érenn, the Welsh tales of the Mabinogion, the Breton lays of Marie de France, the medieval Cornish and Breton drama, and the bardic poetry of Ireland, Wales, and Scotland together form a literary tradition of extraordinary richness, technical sophistication, and historical importance. To study medieval Celtic literature is to enter a world in which the older pagan oral tradition of the Celtic peoples was preserved, transformed, and transmitted by generations of Christian monastic and bardic scholars, and to recognize the importance of this tradition both for the history of the Celtic-speaking regions and for the broader history of European literature. The tradition developed in close relationship with the Celtic language family as a whole, and it is the natural counterpart to the Ogham and other inscribed monuments that preserve the earliest written evidence of the Celtic languages, both of which are essential to the broader story of Celtic languages and oral tradition.
The medieval Celtic literary tradition is essentially a manuscript tradition. Most of what survives of the older oral literature of the Celtic peoples was committed to writing by monastic and secular scholars in the early and central Middle Ages, and the great manuscript collections of the eleventh, twelfth, and later centuries are the principal sources for our knowledge of the tradition. The fact that so much was preserved is itself remarkable, and it reflects the deep commitment of the Celtic-speaking peoples to their literary heritage, a commitment that was shared by Christian monks and secular poets alike.
The Irish Sagas: The Ulster Cycle
The Ulster cycle, also known as the Red Branch cycle or the Rúraíocht, is the earliest and most important of the four great narrative cycles of medieval Irish literature. The cycle centers on the reign of Conchobor mac Nessa at Emain Macha (Navan Fort near modern Armagh), the exploits of the great hero Cú Chulainn, and the heroic fian (warrior band) of the Red Branch. The cycle includes some of the great stories of early medieval European literature, including the foundational Táin Bó Cúailnge (the Cattle Raid of Cooley), the tragic tale of Deirdre, the stories of Fergus mac Róich, Conall Cernach, Lóegaire Búadach, and the other heroes of the Red Branch.
The Táin Bó Cúailnge is the central text of the Ulster cycle and one of the great works of European medieval literature. The story tells of the great cattle raid launched by Medb, the warrior queen of Connacht, and her husband Ailill, against the hero Cú Chulainn and the men of Ulster. The narrative includes some of the most memorable episodes of Celtic heroic literature, including the great single combats, the appearance of the divine bull Donn Cuailnge, and the ríastrad or warp spasm of Cú Chulainn, his terrifying battle frenzy in which his body undergoes grotesque transformations.
The Ulster cycle reflects an older heroic society of the Iron Age Celtic world, a society in which the ties of fosterage, marriage, and clan defined the relationship between the hero and his lord, and in which the personal honor of the warrior and the collective honor of the clan were the principal values. The cycle is also a product of its own time, however, and the manuscripts in which it is preserved date from a millennium after the events they purport to describe. The interplay between the older heroic material and the later Christian and aristocratic context is one of the great features of the tradition.
The Irish Sagas: The Fenian Cycle
The Fenian cycle, also known as the Fiannaigecht or the Ossianic cycle, is the second great narrative cycle of medieval Irish literature. The cycle centers on the exploits of Fionn mac Cumhaill (often anglicized as Finn McCool) and his fian, a band of heroic warriors who roamed the Irish countryside in the third century CE, according to the conventional dating of the legends. The cycle includes the great tales of Acallam na Senórach (the Colloquy of the Ancients), Fionn’s Battle with the Fire-Breathing Monster, Oisín in Tír na nÓg (Oisín in the Land of Youth), and the many tales of Diarmuid Ua Duibhne and Gráinne, whose elopement is one of the great love stories of medieval European literature.
The Fenian cycle is, a more elaborate and more consciously literary tradition than the Ulster cycle. The tales are longer, the characters more developed, and the settings more elaborate, reflecting a later stage in the development of the Irish literary tradition. The Acallam na Senórach is a vast frame narrative in which the aged Oisín and his companion Cailte recount the deeds of the Fianna to St Patrick and the Christian clergy.
The Finn and Oisín tales of the Fenian cycle had an enormous influence on the literature of the rest of Europe, particularly in the eighteenth and nineteenth centuries, when the Ossianic poems of James Macpherson, purported to be translations of the third-century Gaelic bard Oisín, became one of the most widely read works of the Romantic period.
The Mythological Cycle and the Historical Tradition
The third great cycle of medieval Irish literature, the Mythological cycle or the Tuatha Dé Danann cycle, deals with the gods and goddesses of pre-Christian Ireland and with the legendary origins of the Irish people. The principal text of the cycle is the Lebor Gabála Érenn (the Book of Invasions), a complex and elaborate text preserved in manuscripts of the eleventh and later centuries, which traces the supposed history of Ireland from the creation of the world through a series of invasions, each contributing a new element to the population of the island.
The Tuatha Dé Danann, the divine race of the Mythological cycle, are the central figures of the Lebor Gabála and of the related tales of the Battle of Moytura, the Second Battle of Moytura, the Dream of Aengus, and the Wooing of Étaín. The tales preserve a substantial body of older pagan material, often thinly disguised in Christian dress, that gives a vivid picture of the religious and mythological world of pre-Christian Ireland. The great god Lugh, the mother goddess Brigid, the divine Dagda, the war goddess Morrígan, and the divine physician Dian Cecht are among the most important figures of the cycle, and their stories are essential to the broader study of the Celtic gods and goddesses.
The Historical cycle of medieval Irish literature deals with the historical kings of Ireland and with the major events of the early and central medieval period. The cycle includes the Lebor Laignech (the Book of Leinster) collection of historical texts, the Annals of the Four Masters and other historical compilations, and the great tales of Brian Boru and Cormac mac Airt. The cycle reflects the deep concern of the medieval Irish learned class with the historical past.
The Welsh Mabinogion
The Mabinogion is the single most important collection of medieval Welsh prose tales. The title was given to the collection by the translator Lady Charlotte Guest in the nineteenth century, after the Four Branches of the Mabinogi, the four tales that form the mythological core of the collection. The Mabinogion is preserved in two principal manuscripts, the Red Book of Hergest and the White Book of Rhydderch, both of the fourteenth century, and it draws on material that is in some cases much older.
The Four Branches of the Mabinogi are the tales of Pwyll, Branwen, Manawydan, and Math, four interconnected stories that tell of the magical and tragic events surrounding the royal family of Dyfed (the historical Demetia in southwestern Wales). The tales are rich in mythological material, including the Head of Bran the Blessed buried under the Tower of London as a talisman of British sovereignty, the Mabinogi of Math with its strange tale of the boy Gwydion and his transformation through magic, and the Mabinogi of Manawydan with its mysterious mists that turn the land of Dyfed into a wasteland.
The Mabinogion also includes the great Arthurian tales of Culhwch and Olwen, the Dream of Macsen Wledig, the Dream of Rhonabwy, and the medieval romances of Owain, Peredur, and Geraint. The tales of Owain, Peredur, and Geraint are particularly important for the history of European literature, since they are the earliest known versions of the stories of Yvain, Perceval, and Erec, three of the great Arthurian romances of Chrétien de Troyes and the German and English Arthurian traditions.
The Welsh Triads, a collection of grouped lists of persons, places, and events preserved in manuscripts of the thirteenth and fourteenth centuries, are also an important source for the older Welsh mythological and legendary material. The Triads are organized as groups of three, each triad naming three characters or events and identifying them with a brief explanatory note. The Triads preserve a great deal of older material that is not preserved in any other form, and they are an essential source for the reconstruction of early Welsh tradition.
Bardic Poetry and the Professional Poets
The bardic poetry of the Celtic-speaking regions is one of the great achievements of medieval European literature, and the traditions of the bard in Ireland, Wales, and Scotland produced a substantial body of formal verse that ranks with the contemporary traditions of the troubadours and the minnesinger.
The Irish bardic tradition developed a highly sophisticated system of metrics, grammar, and literary composition that became a model for the later bardic traditions of Wales and Scotland. The bardic schools trained students in the complex syllabic verse forms of the classical Irish tradition, in the composition of prose tales in the classical style, and in the mastery of the vast body of traditional lore that was the inheritance of every professional poet. The poets who emerged from this training enjoyed a privileged position in medieval Irish society: they could compose poems of praise that honored a king, poems of satire that could ruin an enemy, and elegies that preserved the memory of the dead.
The Welsh bardic tradition, particularly the tradition of the prydydd or professional poet that flourished from the twelfth through the fourteenth centuries, produced an extraordinary body of formal verse that combines praise of patrons, religious poetry, and elegy. The Welsh poets organized themselves into a formal hierarchy, with the pencerdd (chief poet) at the top. The Welsh Eisteddfod, the formal competitive festival of poetry and music, has its origins in the medieval period.
The Scottish Gaelic bardic tradition of the seventeenth and eighteenth centuries produced a remarkable body of formal verse, including the dan direach and the ornaid. The modern Scottish Gaelic literary tradition continues to this day.
Saints’ Lives and Religious Literature
The saints’ lives of the medieval Celtic world are a distinctive body of hagiographical literature. The Irish Bethu Brigte, the Bethu Phátraic, the Vita Columbae of Adomnán, and the Vita Brigitae of Cogitosus are the most famous examples. The saints’ lives preserve a great deal of older material, including pagan traditions, magical practices, and folk beliefs, and they are an essential source for the social, religious, and intellectual life of early medieval Ireland.
The Welsh Vita Cadoci, the Vita Davidis (the Life of David), the Vita Gildae by Caradoc of Llancarfan, and the Vita Paterni are the most important Welsh examples. The Breton Vita Columbae and the Vita Pauli Aureliani are notable Breton examples. The hagiographical tradition of the Celtic-speaking regions had an important influence on the broader European hagiographical tradition, particularly through the work of the Irish and Welsh scholars who worked in the Carolingian and Ottonian courts.
The religious literature of the Celtic-speaking regions also includes a substantial body of biblical commentary, homiletic literature, devotional poetry, and liturgical texts. The Irish Liber Hymnorum, the Stowe Missal, the Book of Dimma, and the Book of Deer are notable examples.
The Manuscript Tradition
The medieval Celtic literary tradition is preserved in a remarkable series of manuscripts, most of which were produced in monastic scriptoria in Ireland, Wales, Scotland, and Brittany. These manuscripts, often beautifully illuminated, are the work of scribes who combined the older native traditions of craftsmanship with the new Christian learning.
The great manuscripts of the Irish tradition include the Book of Durrow (c. 700 CE), the Book of Kells (c. 800 CE), the Lindisfarne Gospels (c. 700 CE), the Book of the Dun Cow (Lebor na hUidre, c. 1100 CE), the Book of Leinster (c. 1150 CE), the Yellow Book of Lecan (c. 1390 CE), the Great Book of Lecan (c. 1418 CE), and the Book of Ballymote (c. 1390 CE). Each of these manuscripts contains a substantial body of literary, historical, legal, and genealogical material, and the survival of so many great manuscripts is a tribute to the dedication of generations of scholars.
The great manuscripts of the Welsh tradition include the Black Book of Carmarthen (c. 1250 CE), the Book of Aneirin (c. 1265 CE), the Book of Taliesin (c. 1350 CE), the Red Book of Hergest (c. 1400 CE), and the White Book of Rhydderch (c. 1350 CE). The Book of Aneirin contains the Y Gododdin, the great early Welsh heroic poem commemorating the Battle of Catraeth in the sixth century, and the Book of Taliesin contains a substantial collection of medieval Welsh bardic poetry, including the great prophetic poems attributed to the legendary sixth-century bard Taliesin.
