Bealtaine

Bealtaine is the Gaelic festival of summer's beginning, celebrated on 1 May, whose earliest record describes druids driving cattle between two fires against disease, a rite centred on the Hill of Uisneach and still documented in Irish folklore a thousand years later.

Bealtaine is the Gaelic festival of the first day of summer, kept on 1 May. Its oldest record, in Cormac's Glossary around 900, describes twin fires lit with incantations and cattle driven between them against disease. Centred on the Hill of Uisneach, it combined fire, cattle blessing, and protection from the Good People.

PronunciationBYOWL-tin-eh (Irish); the Scottish form Beltane is BEL-tayn

Also known asBealtaine, Bealltaine, Beltane, Beltain, Cétshamhain, Bealtuinn, Boaldyn, May Day

Worth knowing: Bealtaine is the Gaelic festival of summer’s first day, kept on 1 May, and one of the four great Irish quarter-days. Its oldest record, in Cormac’s Glossary around the year 900, describes druids lighting two fires with incantations and driving cattle between them against disease, a rite still found in Irish folklore a thousand years later. Its mythological and archaeological centre is the Hill of Uisneach in Co. Westmeath, the traditional navel of Ireland. The festival joined communal fire, cattle blessing, and protection from the Good People; the name probably means lucky or bright fire, and the reading that it honoured a god Bel is a medieval interpretive layer of uncertain reliability. The fire at Uisneach was revived as a modern festival in 2009.

What is Bealtaine?

Bealtaine is the Gaelic seasonal festival that marks the first day of summer, celebrated on 1 May. It is one of the four great quarter-days of the Irish year, and the medieval sources pair it with Samhain as the two principal hinges on which the year turns: summer from Bealtaine, winter from Samhain. Where Samhain opens the dark half, Bealtaine opens the bright one.

Its defining act is a fire rite for cattle. The community lit two great fires and drove the herd between them to guard the animals against the diseases of the coming year, and around that central rite gathered a wide body of protective custom: the dousing and relighting of household fires, the decorated May bush at the door, yellow flowers strewn against the Good People, and the gathering of May dew at first light. The festival was both a threshold ceremony and a piece of practical animal husbandry as the herds moved to summer pasture.

What does the name Bealtaine mean?

The Old Irish form is belltaine or beltaine, and its earliest source preserves a genuine tension. Cormac’s Glossary, compiled around the year 900 and attributed to the bishop-king Cormac mac Cuilennáin, contains two entries with different readings. The primary entry derives the name from bil-tene, lucky or goodly fire. A separate entry for Bil or Bial calls it an idol god and renders the name as fire of Bel. That internal disagreement is the root of all later debate.

Ronald Hutton has noted that no god named Bel or Belenus is attested anywhere else in the Old Irish record, with no mythology, no cult site, and no place-lore poem to support it. He suggests the glossator may have made a learned comparison with biblical Baal worship rather than preserving an authentic Irish divine name. Geoffrey Keating amplified the Bel reading in the seventeenth century. Against all this stands a reconstructed Celtic form meaning bright fire, which arrives at the same sense without invoking any deity. The scholarly consensus is that the name refers to fire, and probably to brightness or good fortune, and that the god reading is a later interpretive layer of uncertain reliability.

Bealtaine in the medieval sources

Cormac’s Glossary, in the nineteenth-century edition of Whitley Stokes and John O’Donovan, is the oldest and most authoritative witness. Its Belltaine entry reads, in plain summary, that May Day means lucky fire, that is, two fires which the druids used to make with great incantations, and that they used to drive the cattle between them as a safeguard against the diseases of each year. The entry is remarkable for how much it packs in: twin fires, spoken incantation, and a livestock-disease rationale, with the cattle driven between two separate fires, a detail confirmed by almost all the later folklore.

The tale Tochmarc Emire, in Kuno Meyer’s translation, repeats the formula closely: the druids used to make two fires with great incantations and drive the cattle between them against the plagues, every year. The same text sets out the two-fold division of the year, summer from Bealtaine, the first of May, and winter from Samhain to Bealtaine, making the two festivals the great hinges of the calendar.

Keating’s history of Ireland, written around 1634, gives the fullest narrative: the Hill of Uisneach hosted a great Bealtaine assembly where goods were exchanged, and two fires were lit in every district of Ireland, with a weakling of each kind of cattle driven between them as a safeguard against disease for the year. This is a seventeenth-century synthesis drawing on earlier sources, and Keating’s identification of a god at Uisneach builds on Cormac’s Glossary; it should not be treated as independent evidence of pre-Christian practice.

The Metrical Dindshenchas, the verse lore of places in Edward Gwynn’s edition, supplies the founding image in its poem on Mide. The druid Mide lit the first sacred fire at Uisneach, which blazed for seven years across the four quarters of Ireland, and every chief’s hearth was kindled from it. When rival druids objected, Mide summoned them to Uisneach, cut out their tongues, and buried them in the hill. Uisneach is thereby made the literal hearth of Ireland, the origin point of all communal fire.

Uisneach: the hill, the stone, and the digging

The Hill of Uisneach in Co. Westmeath rises to about 182 metres and commands a view said to take in twenty counties. In the mythological tradition it is the omphalos, the navel where Ireland’s five ancient provinces converge. The Aill na Míreann, the Stone of Divisions, also called the Catstone, is a thirty-tonne glacial limestone boulder; tradition holds that the goddess Ériu, from whom Ireland takes its name, lies buried beneath it.

Between 1925 and 1930 the archaeologists R.A.S. Macalister and R.L. Praeger excavated nine sites on the hill. Their work on a large figure-of-eight earthwork found a substantial spread of ash within the ditch holding great quantities of intensely charred animal bone, which they read as strongly suggestive of a sanctuary where fire was kept burning or repeatedly kindled and animal sacrifices were offered. The ash bed does not prove the fires were specifically Bealtaine fires, but it confirms Uisneach as a site of recurrent ritual burning over many centuries. The archaeologist Roseanne Schot later reanalysed the enclosure as a late prehistoric ceremonial site, noting that purificatory rituals involving fire and cattle appear to have had a major part in the Bealtaine celebrations there.

What is genuinely ancient about Bealtaine?

In his history of the ritual year, Ronald Hutton treats Bealtaine as carrying stronger ancient credentials than most British and Irish seasonal customs. The two-fire and cattle rite is documented around the year 900 in Cormac’s Glossary and confirmed as a living rural practice in nineteenth-century accounts from Munster and Leinster. In Britain the fires were kindled by friction, the so-called need-fire, with all metal removed and all other fires extinguished, which matches the Irish accounts of household fires being doused on May Eve and relit from the communal blaze. Hutton is explicit, however, that attaching the fires to a named deity is a later interpretive layer rather than part of the early evidence.

The folk custom: May bush, yellow flowers, butter, and dew

Kevin Danaher’s survey of the Irish year is the standard synthesis of the folk record. The May bush, a whitethorn branch decorated with flowers, ribbons, and eggshells, was set up outside the house on May Eve; an observer in 1682 noted that every family set a green bush strewn with yellow flowers before the door. Yellow flowers, primroses, marsh marigolds, and gorse, were laid on doorsteps, windowsills, and byres, their solar colour standing between the household and the Good People. May morning dew, gathered by young women before sunrise, was believed to preserve beauty, cure ailments, and bring luck.

The most urgent anxieties of the folk record centred on dairy and on fire taboos. No coal, flame, salt, or milk should be given to any neighbour on May morning, for to do so was to transfer one’s cattle’s milk-luck for the whole year. A butter-stealing witch might drag a rope through the May dew across a neighbour’s land to claim the year’s churning yield, and in dozens of Connacht and Munster accounts she takes the form of a hare that ordinary shot cannot stop, only silver. The Dúchas Schools’ Collection entry from Cloonaghboy in Co. Mayo, contributed by Michael Durkan in 1937, confirms the local register directly: if you give away salt or a coal on May Day you will have bad luck for the year, and cows should not be let out until after midday, because the fairies might steal them.

The Good People and the Bridget Cleary case

Bealtaine, like Samhain, was a threshold when the otherworld boundary thinned. The Good People, na Daoine Maithe, were abroad and dangerous, and this was changeling season, when a healthy adult or child might be swept into the fairy realm and replaced with a withered impostor. Protective measures multiplied: yellow flowers at the threshold, iron near the cradle, holy water on the cattle.

The starkest historical evidence for how seriously this belief was held in the living-custom era is the death of Bridget Cleary in Co. Tipperary in 1895, documented in Angela Bourke’s scholarly study The Burning of Bridget Cleary. Convinced his wife had been replaced by a changeling, Michael Cleary tortured and burned her to death in March 1895, and was convicted of manslaughter, the court accepting that the belief was genuinely held. Bourke argues that male violence and anxiety about an unusually independent woman were central, while placing the case within an unbroken folk-belief tradition. The Cleary case is not strictly a Bealtaine story, since it fell in March, but it is the clearest proof of how real fairy-abduction belief remained at the very moment when the Bealtaine customs of the Dúchas record were living practice.

Booleying: the road to summer pasture

Bealtaine was inseparable from booleying, the practice of driving cattle from the winter lowlands to upland grazing from around May Day until September. The rite of the two fires was both a purification for the journey ahead and a piece of practical medicine, since the smoke killed parasites. In Mayo and Connacht this tradition was among the most deeply rooted in the west. Stone booley huts survive on Achill Island above Keel, and oral tradition from west Mayo and Connemara, collected by the Irish Folklore Commission in the 1930s, describes the seasonal movement vividly, with the songs of the dairymaids. The Mayo proverb that a person is between the two Bealtaine fires, meaning caught in an impossible dilemma, keeps the physical memory of the rite alive in everyday speech.

The modern revival, and two festivals of one name

The Bealtaine fire at Uisneach lapsed in the early modern period. In 2009 the family who farm the hill revived it as a fire festival on the site, drawing on its verifiable ancient associations, and it has grown substantially since. In 2017 President Michael D. Higgins lit the ceremonial fire, confirmed as the first Irish head of state to do so since the era of the last High Kings, nearly a thousand years before. The organisers are explicit that the festival was revived in 2009: this is a modern revival on a genuinely ancient site, and the clarity of that distinction is part of what gives the event its integrity.

A wholly separate institution shares the name. The Bealtaine Festival run by Age and Opportunity, established in 1995, is Ireland’s national festival of arts and creativity in older age, held across the whole month of May nationwide. It takes its name from the Irish word for May and from the threshold symbolism of the season, but it has no operational connection to the Uisneach fire ceremony and should be carefully distinguished from it.

Common misconceptions

The claim The Bealtaine fires honoured a Celtic god named Bel or Belenus.

The correction This rests on a secondary entry in Cormac's Glossary that derives the name from an idol god Bel. The primary entry in the same text derives it from bil-tene, lucky fire. Ronald Hutton notes that no god Bel or Belenus is attested anywhere else in Old Irish, with no mythology, cult site, or prayer; the writer may have been drawing a comparison with biblical Baal. A reconstructed form meaning bright fire reaches the same sense with no deity at all.

The claim The Uisneach Bealtaine fire is an unbroken ancient tradition.

The correction The hill is genuinely ancient, with five millennia of activity, deep ash deposits from the 1920s excavations, and medieval association with a Bealtaine assembly. But the current festival is a revival, begun deliberately in 2009 on an authentic ancient site. The organisers are themselves clear about the distinction, and the accuracy is part of what gives the event its standing.

The claim Bealtaine was mainly a feast of sexual licence and fertility.

The correction This is a Victorian projection shaped by Frazer's Golden Bough. The available Irish evidence centres on cattle health, fire purification, and protection from supernatural danger, not sexual fertility rites. The dominant register of the folklore record is anxious and protective rather than celebratory.

The claim Refusing to give fire to a neighbour on May morning was just a social custom.

The correction In the folk record it was a magical transfer, not a social slight. Danaher and the Dúchas Schools' Collection agree that to give away a coal, flame, salt, or milk on May Day was to hand over the household's dairy and cattle luck for the whole year. The taboo marks May morning as the most vulnerable moment in the annual cycle.

Frequently asked questions

What is Bealtaine?

Bealtaine is the Gaelic seasonal festival marking the first day of summer, celebrated on 1 May. It is one of the four great Irish quarter-days, paired with Samhain as the two principal hinges of the year. Its defining rite, attested around the year 900, drives cattle between two fires lit with incantations to guard them from disease.

What did people do at Bealtaine?

Communities lit twin fires and drove cattle between them as protection against the year's diseases, doused household hearths and relit them from the communal blaze, set a decorated May bush at the door, strewed yellow flowers on thresholds and byres against the Good People, and gathered May dew at dawn for beauty and luck.

Where does the name Bealtaine come from?

The earliest source, Cormac's Glossary, gives two readings: bil-tene, lucky or goodly fire, and a separate gloss deriving it from a god Bel, fire of Bel. Since no god Bel is attested elsewhere in Old Irish, scholars favour the fire reading. A reconstructed form meaning bright fire reaches the same sense without any deity.

Where was Bealtaine celebrated?

Its mythological and archaeological centre is the Hill of Uisneach in Co. Westmeath, held in tradition to be the navel of Ireland where the five provinces met. Excavation there found deep ash beds and charred animal bone from recurrent ritual burning. The festival was also kept across the country, with strong cattle-driving custom in Mayo and Connacht.

Was Bealtaine a fertility festival?

Victorian writers, shaped by Frazer's Golden Bough, projected a fertility cult onto it, but the Irish evidence centres on cattle health, fire purification, and protection from supernatural danger. The dominant tone of the folk record is anxious and protective rather than celebratory, concerned above all with safeguarding milk, butter, and herd through the coming year.

Is the Uisneach Bealtaine fire an ancient unbroken tradition?

The hill is genuinely ancient, with five millennia of activity and medieval association with a Bealtaine assembly, but the fire had lapsed and the present festival is a revival begun in 2009. In 2017 President Michael D. Higgins lit the fire, the first Irish head of state to do so since the era of the High Kings.
