At the beginning of August, when the first grain was ripening in the fields and the long hungry weeks of summer were ending, the people of early Ireland held one of the four great festivals of their year: Lughnasadh (pronounced roughly LOO-nuh-suh). It was a time of assemblies and fairs, horse races and athletic contests, marriages and matchmaking, and climbing to the tops of hills to gather the first fruits. According to myth, it was founded by the god Lugh himself as a funeral feast for the woman who had raised him.
The festival survived Christianity, surviving in new forms for more than a thousand years. Its name lives on in the Irish word for August, Lúnasa, and its customs continued in rural Ireland into the twentieth century.
The Four Festivals
The early Irish calendar was divided by four great festivals, marking the quarters of the year:
- Samhain (1 November), the beginning of winter and the start of the year, when the boundary between the world of the living and the Otherworld grew thin.
- Imbolc (1 February), the beginning of spring, associated with lambing and the goddess Brigid.
- Beltaine (1 May), the beginning of summer, when cattle were driven between two fires and taken to summer pastures.
- Lughnasadh (1 August), the beginning of autumn and the harvest.
These festivals were tied to the farming and herding cycle, not to the solstices and equinoxes. Lughnasadh stood midway between the summer solstice and the autumn equinox.
The Myth of Tailtiu
The medieval Dindshenchas (“Lore of Places”) and the Lebor Gabála Érenn tell the origin of the festival. Tailtiu was a queen of the Fir Bolg, the people who ruled Ireland before the Tuatha Dé Danann. After her people were defeated, she became the foster-mother of the young Lugh.
Tailtiu took on an enormous task: clearing the great forest of Coill Cuan so that the land of Meath could be ploughed and sown. She cut down the trees with an axe until the plain was ready for cultivation. But the effort was too great, and she died of exhaustion.
Before she died, she asked that funeral games be held in her honour every year. Lugh established the Óenach Tailten, the Assembly of Tailtiu, at the place where she was buried — Teltown, on the River Blackwater between Navan and Kells in County Meath. The games were held on the first of August, and as long as they were observed, the story says, Ireland would have grain and milk, peace and justice.
The myth reflects a real transformation of the landscape: the clearance of woodland for agriculture, and the heavy human cost of making the land fertile.
The Assembly of Tailtiu
The Óenach Tailten became one of the great national assemblies of early medieval Ireland, presided over by the high king. Medieval sources describe:
- Horse and chariot races.
- Athletic contests: running, jumping, spear-throwing, wrestling, and swimming.
- Legal proceedings and the proclamation of laws.
- Trading and markets.
- Storytelling, music, and poetry.
- Marriages, including the so-called “Teltown marriages”: couples could be joined at the festival in a trial union for a year and a day, and could separate at the next year’s festival by standing back to back and walking apart. (The historical basis for this custom is uncertain; it may be partly a later romantic tradition.)
The Óenach Tailten continued, with interruptions, until the twelfth century. In 1924 the new Irish Free State revived it as the Tailteann Games, an international sporting festival for people of Irish descent, held three times before the tradition lapsed.
Lugh and the Harvest
Why should Lugh, the shining master of all arts, be associated with the harvest? Several ideas have been proposed.
The folklorist Máire MacNeill, whose monumental study The Festival of Lughnasa (1962) remains the foundational work on the subject, reconstructed a myth underlying the festival’s customs. She argued that it enacted a struggle between Lugh and a dark god, often identified as Crom Dubh (“the black crooked one”), for the grain. Crom Dubh guarded the harvest, keeping it underground, and Lugh won it for the people. In some folk tales, Crom Dubh was a pagan chieftain converted by Saint Patrick, and the festival’s last Sunday of July became Crom Dubh Sunday.
MacNeill identified at least 195 sites in Ireland where Lughnasadh customs were observed in modern times, mostly on hilltops and by lakes and holy wells.
The Customs of Lughnasadh
From MacNeill’s research and other folklore collections, a rich picture of Lughnasadh customs emerges:
- Climbing hills and mountains. Communities gathered on hilltops for a day of festivity. The most famous survival is the pilgrimage up Croagh Patrick in County Mayo on the last Sunday of July, known as Reek Sunday, when tens of thousands of people still climb the mountain, some barefoot. The Christian pilgrimage almost certainly continues an older Lughnasadh gathering.
- Gathering bilberries. On the hillsides, young people picked bilberries (blueberries, also called “fraughans” or “whorts”). The size of the crop was taken as a sign of the harvest to come. It was also a time of courtship.
- The first fruits. The first sheaf of grain or the first new potatoes were ceremonially cut, cooked, and eaten. There was a strong taboo against cutting the harvest before the festival; to do so was to risk hunger.
- Fairs and horse racing. Many rural fairs held around the first of August, such as Puck Fair in Killorglin, County Kerry — where a wild goat is crowned king for three days — may continue Lughnasadh traditions.
- Bathing cattle and horses in lakes and rivers for their health.
- Faction fights, in which rival groups of young men fought with sticks — a rougher echo of the ancient athletic contests.
Lammas
In England, the equivalent festival was Lammas (from Old English hlāf-mæsse, “loaf mass”), when bread made from the first grain of the harvest was brought to church and blessed. It fell on the same date, August 1st. Scotland had Lùnastal, with its own harvest fairs, and the Isle of Man had Laa Luanys. In Wales, the date was called Gŵyl Awst, “the August feast.”
Lughnasadh in the Modern World
Lughnasadh has been revived as one of the eight “sabbats” of the Wheel of the Year in modern Wicca and neo-paganism, where it is often called Lughnasadh or Lammas and celebrated as the first harvest. Modern Celtic polytheists and reconstructionists also mark it, often with gatherings on hilltops.
The festival also gave its name to Brian Friel’s celebrated play Dancing at Lughnasa (1990), set in County Donegal in 1936, in which five sisters, living under economic pressure and strict Catholic morality, are drawn to the “pagan” harvest festival taking place in the hills above their home. The play, and the 1998 film adaptation starring Meryl Streep, brought the name of the ancient festival to an international audience.
A Festival of Gratitude and Sacrifice
At its heart, Lughnasadh expresses gratitude for the harvest and acknowledges its cost. Tailtiu dies clearing the land; the grain must be won from the dark powers that hold it; and the people climb to the hilltops to celebrate the moment when the hungry season ends. Lugh, the bright young god, presides over the triumph of skill and labour over scarcity — and every year, the triumph is renewed.
