Irish mythology in the context of Ethniu

Irish literature is literature written in the Irish, Latin, English and Scots (Ulster Scots) languages on the island of Ireland. The earliest recorded Irish writing dates from back in the 7th century and was produced by monks writing in both Latin and Early Irish, including religious texts, poetry and mythological tales. There is a large surviving body of Irish mythological writing, including tales such as Táin Bó Cúailnge and Buile Shuibhne.

The English language was introduced to Ireland in the 13th century, following the Norman invasion of Ireland. The 16th and 17th centuries saw a major expansion of English power across Ireland, further expanding the presence of early Modern English speakers. One theory is that in the latter part of the nineteenth century saw a rapid replacement of Irish by English in the greater part of the country, largely due to the Great Famine and the subsequent decimation of the Irish population by starvation and emigration. Another theory among modern scholars is that far from being a sudden cataclysmic event the language shift was well underway much earlier. At the end of the century, however, cultural nationalism displayed a new energy, marked by the Gaelic Revival (which encouraged a modern literature in Irish) and more generally by the Irish Literary Revival.

Celtic mythology is the body of myths belonging to the Celtic peoples. Like other Iron Age Europeans, Celtic peoples followed a polytheistic religion, having many gods and goddesses. The mythologies of continental Celtic peoples, such as the Gauls and Celtiberians, did not survive their conquest by the Roman Empire, the loss of their Celtic languages and their subsequent conversion to Christianity. Only remnants are found in Greco-Roman sources and archaeology. Most surviving Celtic mythology belongs to the Insular Celtic peoples (the Gaels of Ireland and Scotland; the Celtic Britons of western Britain and Brittany). They preserved some of their myths in oral lore, which were eventually written down by Christian scribes in the Middle Ages. Irish mythology has the largest written body of myths, followed by Welsh mythology.

The supernatural race called the Tuatha Dé Danann is believed to be based on the main Celtic gods of Ireland, while many Welsh characters belong either to the Plant Dôn ("Children of Dôn") or the Plant Llŷr ("Children of Llŷr"). Some figures in Insular Celtic myth have ancient continental parallels: Irish Lugh and Welsh Lleu are cognate with Lugus, Goibniu and Gofannon with Gobannos, Macán and Mabon with Maponos, and so on. One common figure is the sovereignty goddess, who represents the land and bestows sovereignty on a king by marrying him. The Otherworld is also a common motif, a parallel realm of the supernatural races, which is visited by some mythical heroes. Celtic myth influenced later Arthurian legend.

The culture of Ireland includes the art, music, dance, folklore, theatre, traditional clothing, language, literature, cuisine and sport associated with Ireland and the Irish people. For most of its recorded history, the country’s culture has been primarily Gaelic (see Gaelic Ireland). Strong family values, wit and an appreciation for tradition are commonly associated with Irish culture.

Irish culture has been greatly influenced by Christianity, most notably by the Roman Catholic Church, and religion plays a significant role in the lives of many Irish people. Today, there are often notable cultural differences between those of Catholic, Protestant and Orthodox background. References to God can be found in spoken Irish, notably exemplified by the Irish equivalent of “Hello” — “Dia dhuit” (literally: "God be with you").

Gaelic Ireland (Irish: Éire Ghaelach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the late prehistoric era until the 17th century. It comprised the whole island before Anglo-Normans conquered parts of Ireland in the 1170s. Thereafter, it comprised that part of the country not under foreign dominion at a given time (i.e. the part beyond The Pale). For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were chosen or elected through tanistry. Warfare between these territories was common. Traditionally, a powerful ruler was acknowledged as High King of Ireland. Society was made up of clans and, like the rest of Europe, was structured hierarchically according to class. Throughout this period, the economy was mainly pastoral and money was generally not used. A Gaelic Irish style of dress, music, dance, sport and art can be identified, with Irish art later merging with Anglo-Saxon styles to create Insular art.

Gaelic Ireland was initially pagan and had an oral culture maintained by traditional Gaelic storytellers/historians, the seanchaidhthe. Writing, in the form of inscription in the ogham alphabet, began in the protohistoric period, perhaps as early as the 1st century. The conversion to Christianity, beginning in the 5th century, accompanied the introduction of literature. In the Middle Ages, Irish mythology and Brehon law were recorded by Irish monks, albeit partly Christianized. Gaelic Irish monasteries were important centres of learning. Irish missionaries and scholars were influential in western Europe and helped to spread Christianity to much of Britain and parts of mainland Europe.

A triple deity is a deity with three apparent forms that function as a singular whole. Such deities may sometimes be referred to as threefold, tripled, triplicate, tripartite, triune, triadic, or as a trinity. The number three has a long history of mythical associations and triple deities are common throughout world mythology. Carl Jung considered the arrangement of deities into triplets an archetype in the history of religion.

In classical religious traditions, three separate beings may represent either a triad who typically appear as a group (the Greek Moirai, the Roman Parcae, the Norse Norns, the Baltic Dēkla, Kārta and Laima, or the Irish Badb, Macha and Morrígan), or a single deity notable for having three aspects (Greek Hecate and Islamic Hermes Trismegistus). Trinitarian Christianity instead recognizes three "divine persons" in God the Father, the Son, and the Holy Spirit, which are usually distinguished from the idea of independent gods or aspects.

County Armagh (Irish: Contae Ard Mhacha [ˌaːɾˠd̪ˠ ˈwaxə]) is one of the six counties of Northern Ireland and one of the traditional thirty-two counties of Ireland. It is located in the province of Ulster and adjoins the southern shore of Lough Neagh. It borders the Northern Irish counties of Tyrone to the west and Down to the east. The county borders Louth and Monaghan to the south and southwest, which are in the Republic of Ireland. It is named after its county town, Armagh, which derives from the Irish Ard Mhacha, meaning "Macha's height". Macha was a sovereignty goddess in Irish mythology and is said to have been buried on a wooded hill around which the town of Armagh grew. County Armagh is colloquially known as the "Orchard County" because of its many apple orchards.

The county covers an area of 1,327 km (512 sq mi), making it the smallest of Northern Ireland's six counties by size and the sixth-smallest county on the island of Ireland. With a population of 194,394 as of the 2021 census, it is the fourth-most populous county in both Northern Ireland and Ulster. It is the 10th most populous of Ireland's 32 traditional counties, as well as the fifth-most densely populated. In addition to the city of Armagh and the western portion of the city of Newry, notable towns in the county include Lurgan, Portadown and Craigavon.

The Irish (Irish: Na Gaeil or Na hÉireannaigh) are an ethnic group and nation native to the island of Ireland, who share a common ancestry, history and culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also conquered parts of Ireland in the 12th century, while England's 16th/17th century conquest and colonisation of Ireland brought many English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Ireland) and Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities including Irish, British or some combination thereof.

The Irish have their own unique customs, language, music, dance, sports, cuisine and mythology. Although Irish (Gaeilge) was their main language in the past, today most Irish people speak English as their first language. Historically, the Irish nation was made up of kin groups or clans, and the Irish also had their own religion, law code, alphabet and style of dress.

Robert von Ranke Graves (24 July 1895 – 7 December 1985) was an English poet, novelist and critic. His father was Alfred Perceval Graves, a celebrated Irish poet and figure in the Gaelic revival; they were both Celticists and students of Irish mythology.

Robert Graves produced more than 140 works in his lifetime. His poems, his translations and innovative analysis of the Greek myths, his memoir of his early life—including his role in World War I—Good-Bye to All That (1929), and his speculative study of poetic inspiration The White Goddess have never been out of print. He was also a renowned short story writer, with stories such as "The Tenement" still being popular today.

A leprechaun (Irish: lucharachán/leipreachán/luchorpán) is a diminutive supernatural being in Irish folklore, classed by some as a type of solitary fairy. They are usually depicted as little bearded men, wearing a coat and hat, who partake in mischief. In later times, they have been depicted as shoe-makers who have a hidden pot of gold at the end of the rainbow.

Leprechaun-like creatures rarely appear in Irish mythology and only became prominent in later folklore.

Aos sí (pronounced [iːsˠ ˈʃiː]; English approximation: /iːs ˈʃiː/ eess SHEE; older form: aes sídhe [eːsˠ ˈʃiːə]) is the Irish name for a supernatural race in Gaelic folklore, similar to elves. They are said to descend from the Tuatha Dé Danann or the gods of Irish mythology.

The name aos sí means "folk of the sí"; these are the burial mounds in which they are said to dwell, which are seen as portals to an Otherworld. Such abodes are referred to in English as 'shee', 'fairy mounds', 'elf mounds' or 'hollow hills'. The aos sí interact with humans and the human world. They are variously said to be the ancestors, the spirits of nature, or goddesses and gods.

William Butler Yeats (/jeɪts/ YAYTS; 13 June 1865 – 28 January 1939) was an Irish poet, dramatist, writer and literary critic who was one of the foremost figures of 20th-century literature. He was a driving force behind the Irish Literary Revival and, along with John Millington Synge and Lady Gregory, founded the Abbey Theatre, serving as its chief during its early years. He was awarded the 1923 Nobel Prize in Literature and later served two terms as a Senator of the Irish Free State.

A Protestant of Anglo-Irish descent, Yeats was born in Sandymount, Ireland. His father practised law and was a successful portrait painter. He was educated in Dublin and London and spent his childhood holidays in County Sligo. He studied poetry from an early age, when he became fascinated by Irish legends and the occult. While in London he became part of the Irish literary revival. His early poetry was influenced by John Keats, William Wordsworth, William Blake and many more. These topics feature in the first phase of his work, lasting roughly from his student days at the Metropolitan School of Art in Dublin until the end of the 19th century. His earliest volume of verse was published in 1889, and its slow-paced, modernist and lyrical poems display debts to Edmund Spenser, Percy Bysshe Shelley and the poets of the Pre-Raphaelite Brotherhood.

Táin Bó Cúailnge (Modern Irish pronunciation: [ˈt̪ˠaːnʲ bˠoː ˈkuəlʲɲə]; "the driving-off of the cows of Cooley"), commonly known as The Táin or less commonly as The Cattle Raid of Cooley, is an epic from Irish mythology. It is often called "the Irish Iliad", although like most other early Irish literature, the Táin is written in prosimetrum, i.e. prose with periodic additions of verse composed by the characters. The Táin tells of a war against Ulster by Queen Medb of Connacht and her husband King Ailill, who intend to steal the stud bull Donn Cuailnge. Due to a curse upon the king and warriors of Ulster, the invaders are opposed only by the young demigod, Cú Chulainn.

The Táin is traditionally set in the 1st century in a pagan heroic age, and is the central text of a group of tales known as the Ulster Cycle. It survives in three written versions or "recensions" in manuscripts of the 12th century and later, the first a compilation largely written in Old Irish, the second a more consistent work in Middle Irish, and the third an Early Modern Irish version.

The Gaelic revival (Irish: Athbheochan na Gaeilge) was the late-nineteenth-century national revival of interest in the Irish language (also known as Gaelic) and Irish Gaelic culture (including folklore, mythology, sports, music, arts, etc.). Irish had diminished as a spoken tongue, remaining the main daily language only in isolated rural areas, with English having become the dominant language in the majority of Ireland.

Interest in Gaelic culture was evident early in the nineteenth century with the formation of the Belfast Harp Society in 1808 and the Ulster Gaelic Society in 1830, and later in the scholarly works of Robert Shipboy MacAdam, John O'Donovan and Eugene O'Curry, and the foundation of the Ossianic Society. Concern for spoken Irish led to the formation of the Society for the Preservation of the Irish Language in 1876, and the Gaelic Union in 1880. The latter produced the Gaelic Journal. Irish traditional sports were fostered by the Gaelic Athletic Association, founded in 1884.

Cú Chulainn (/kuːˈkʌlɪn/ koo-KHUL-in Irish: [kuːˈxʊlˠɪn̠ʲ] ), is an Irish warrior hero and demigod in the Ulster Cycle of Irish mythology, as well as in Scottish and Manx folklore. He is believed to be an incarnation of the Irish god Lugh, who is also his father. His mother is the mortal Deichtine, sister of King Conchobar mac Nessa.

Born Sétanta, he gained his better-known name as a child, after killing Culann's fierce guard dog in self-defence and offering to take its place until a replacement could be reared, hence he became the "Hound (cú) of Culann". He was trained in martial arts by Scáthach, who gave him the spear Gáe Bulg. It was prophesied that his great deeds would give him everlasting fame, but that his life would be short. At the age of seventeen he defended Ulster single-handedly against the armies of Queen Medb of Connacht in the famous Táin Bó Cúailnge ("Cattle Raid of Cooley"). He is known for his terrifying battle frenzy (ríastrad), in which he becomes an unrecognisable monster who knows neither friend nor foe. He fights from his chariot, driven by his loyal charioteer Láeg and drawn by his horses, Liath Macha and Dub Sainglend.

Sauron (/ˈsaʊərɒn/) is the title character and the main antagonist in J. R. R. Tolkien's The Lord of the Rings, where he rules the land of Mordor. He has the ambition of ruling the whole of Middle-earth using the power of the One Ring, which he has lost and seeks to recapture. In the same work, he is identified as the "Necromancer" of Tolkien's earlier novel The Hobbit. The Silmarillion describes him as the chief lieutenant of the first Dark Lord, Morgoth. Tolkien noted that the Ainur, the "angelic" powers of his constructed myth, "were capable of many degrees of error and failing", but by far the worst was "the absolute Satanic rebellion and evil of Morgoth and his satellite Sauron". Sauron appears most often as "the Eye", as if disembodied.

Tolkien, while denying that absolute evil could exist, stated that Sauron came as near to a wholly evil will as was possible. Commentators have compared Sauron to the title character of Bram Stoker's 1897 novel Dracula, and to Balor of the Evil Eye in Irish mythology. Sauron is briefly seen in a humanoid form in Peter Jackson's film trilogy, which otherwise shows him as a disembodied, flaming Eye.

The beheading game is a literary trope found in Irish mythology and medieval chivalric romance. The trope consists of a stranger who arrives at a royal court and challenges a hero to an exchange of blows: the hero may decapitate the stranger, but the stranger may then inflict the same wound upon the hero. The supernatural nature of the stranger, which makes this possible, is only revealed when he retrieves his severed head. When the hero submits himself to the return blow, he is rewarded for his valour and is left with only a minor wound. The hero is seen as coming of age by undergoing the exchange of blows, and his symbolic death and rebirth is represented by the feigned return blow.

Originating in the Irish legend of the Fled Bricrenn, the beheading game appears in several Arthurian romances, most notably Sir Gawain and the Green Knight. The version of the game found in the latter work has been analyzed for its relationship with the Arthurian concept of chivalry. At no point does the Green Knight specify that he must be beheaded, only that he will return whatever blow is struck. When Gawain makes the impulsive decision to decapitate the Knight, the values of Camelot require that he subject himself to death in the name of upholding the rules of the challenge. Gawain is incapable of bravely submitting to death, instead concealing a magic girdle that he believes will keep him from harm, thus demonstrating that he values survival over honour.

Samhain (/ˈsɑːwɪn/ SAH-win, /ˈsaʊɪn/ SOW-in; Irish: [ˈsˠəunʲ]; Scottish Gaelic: [ˈs̪ãũ.ɪɲ]) or Sauin (Manx: [ˈsoːɪnʲ]) is a Gaelic festival on 1 November marking the end of the harvest season in autumn and beginning of winter or the "darker half" of the year. It is also the Irish and Scottish Gaelic name for November. Celebrations begin on the evening of 31 October, since the Celtic day began and ended at sunset. This is about halfway between the autumnal equinox and winter solstice. It is one of the four Gaelic seasonal festivals along with Imbolc, Bealtaine, and Lughnasa. Historically it originated in Ireland and it was widely observed throughout Ireland, Scotland, and the Isle of Man. Its Brittonic Celtic equivalent is called Calan Gaeaf in Wales.

Samhain is believed to have Celtic pagan origins, and some Neolithic passage tombs in Great Britain and Ireland are aligned with the sunrise at the time of Samhain. Samhain is mentioned in the earliest Irish literature, from the 9th century, and is associated with many important events in Irish mythology. The early literature says Samhain was marked by great gatherings and feasts and was when the ancient burial mounds were open, which were seen as portals to the Otherworld. Some of the medieval tales also associate Samhain with bonfires and sacrifice.
