Samhain

Worth knowing: Samhain is the Gaelic festival of summer’s end and winter’s onset, kept from sunset on 31 October through 1 November, and the oldest of the four Irish seasonal quarter-days in the written record. In the medieval tales it is the night the otherworld mounds stand open and mortal and otherworldly meet; it is not, on the medieval evidence, a festival of the dead, nor a proven Celtic New Year. Its folk customs of guising, lanterns, and divination travelled with Irish and Scottish emigrants to North America and returned, transformed, as Halloween. The popular image of a thinning veil is a modern poetic addition, not an ancient one.

What is Samhain?

Samhain is the Gaelic seasonal festival that marks the close of the harvest half-year and the beginning of winter. It is kept from sunset on 31 October through 1 November, a reckoning that counts the day from the previous evening, so the night named Oíche Shamhna belongs to the festival itself. Of the four great Irish quarter-days, Samhain, Imbolc, Bealtaine, and the harvest festival, it is the earliest attested and the most fully documented in the surviving literature.

Its character in the medieval texts is consistent: Samhain is the turning point of the year, the threshold between the bright half and the dark half, and the one night when the boundary between the mortal world and the otherworld is at its most porous. Assemblies gather, feasts are held, and the mounds called síde stand open. That is the festival the storytellers reach for whenever a tale needs a moment when anything might cross over.

What does the word Samhain mean?

The Irish word, written samain, samuin, or samhain, has prompted genuine scholarly debate. The most widely accepted analysis parses it as sam, summer, joined to a second element related to fuin, meaning end or setting, and so summer’s end. This reading runs through the literary tradition itself: the tale Tochmarc Emire describes Samhain as the time when the summer goes to its rest.

The standard dictionary of the early language lists samain as both the festival and the word for the month of November, while noting that the derivation is not entirely transparent. Summer’s end is functionally accepted, but it is not proven in strict comparative terms. An alternative reading, assembly, has occasionally been proposed on the strength of the festival’s link with royal gatherings, but it carries less linguistic support. In modern Irish, the month of November remains Samhain.

How pronounced is Samhain?

The festival is sounded roughly SAH-win. In Irish the medial mh is a softened, lenited consonant realised as a w, which is why the written form misleads a reader who approaches it as English. It produces neither an h nor a hard n in the middle. The frequently heard sam-HAYNE is an anglophone misreading that spread through neopagan and fantasy literature in the twentieth century; it has no basis in Irish phonology.

Samhain in the medieval Irish tales

The medieval evidence for Samhain is textual and abundant, but its nature has to be held carefully. These are narrative sources, set down by Christian monks, that deploy Samhain as a dramatic setting; they are not reports on pre-Christian religious practice. Within that frame, the festival recurs as the literature’s favourite hinge.

In the Táin Bó Cúailnge, the great cattle-raid epic, the expedition sets out on the Monday after the autumn festival of Samain, in Cecile O’Rahilly’s edition of the earliest recension, and the famous debility of the Ulstermen runs from that Monday until the following spring. The four-fold division of the year is named most clearly in the riddling speech of Emer in Tochmarc Emire, presented in Thomas Kinsella’s translation, which runs from Samhain, when the summer goes to its rest, through Imbolc and Beltine to the autumn festival. These four points are real medieval evidence for the seasonal structure of the Irish year; they are not proof of a universal Celtic new year on 1 November.

The most atmospheric rendering of Samhain’s otherworldly side is Echtra Nerai, the Adventure of Nera, edited and translated by Kuno Meyer, a tale rooted in the landscape of Connacht. It opens on a Samhain night with Ailill and Medb at Rath Cruachan, and states plainly that the fairy-mounds of Ireland are always open about this time. Two captives hang on the gallows, and Ailill challenges his household to tie a withe around a corpse’s foot on this most dangerous night, when, the text says, the darkness and horror are great and demons walk. Nera alone succeeds, follows a spectral host, and enters the mound at Cruachan, where he learns of a planned Samhain raid on the royal fort. The mound is at Cruachan, today Rathcroghan in Co. Roscommon, and specifically the cave of Oweynagat, the Cave of the Cats. As early as the twelfth-century Book of Leinster this cave is named Ireland’s gate to the underworld. Rathcroghan lies wholly within Connacht; Co. Mayo adjoins it and shares the same provincial tradition.

In Cath Maige Tuired, the second battle of Mag Tuired, in Elizabeth Gray’s edition, the Dagda keeps a yearly tryst with a woman near the festival, by a river in Corann. She is the Morrígan, and she counsels him for the coming war against the Fomorians, which itself falls at Samhain. The popular phrase that the Dagda and the Morrígan couple at Samhain is broadly accurate but a little loose: their meeting falls around the festival, the battle is set at it, and the surviving English text marks the time as All Hallows rather than using the word samain itself. The text shows divine powers active at this juncture; it does not speak of a thinning veil.

The Fenian tradition gives Samhain one of its sharpest stories. In the lore carried in the Acallam na Senórach and related texts, translated by Ann Dooley and Harry Roe, the otherworld musician Aillén mac Midgna travels each Samhain from his mound to Tara, plays a sleep-inducing music that lulls the assembly unconscious, then breathes fire and burns the palace. The cycle repeats for years until the young Fionn mac Cumhaill holds a poisoned spear-point to his own forehead to fight off the sleep, kills Aillén as he flees toward his mound, and so wins command of the Fianna. The whole story depends on Samhain as the one annual opening when such a crossing can happen. The Ulster tale Serglige Con Culainn, the wasting sickness of Cú Chulainn, likewise opens at a Samhain feast at Emain Macha, where the hero’s otherworldly visions begin.

Did the veil thin at Samhain?

The phrase that the veil between worlds is thin at Samhain is modern, not medieval. The early Irish texts show the mounds standing open and otherworldly beings moving freely; Echtra Nerai says it directly, that the fairy-mounds of Ireland are always open about this time, and Cath Maige Tuired places divine encounter and battle at the same moment. None of these sources use any language that translates as veil. The metaphor entered English descriptions through nineteenth and early twentieth-century romantic and spiritualist writing. It is a serviceable poetic image, but it should not be credited to the ancient sources.

The fire tradition at Tlachtga

The most specific account of a Samhain fire ritual comes late. Seathrún Céitinn, Geoffrey Keating, writing his history of Ireland around 1634, more than six centuries after the events it describes, has druids assemble at Tlachtga, the Hill of Ward near Athboy in Co. Meath, to light a great Samhain fire from which all the hearths of Ireland were then rekindled. Ronald Hutton treats Keating as a thoroughly unreliable antiquary and argues that the account reads like a medieval Christian construction assembled from fire customs of other seasons. The Tlachtga tradition is best understood as a seventeenth-century literary elaboration rather than a confirmed pre-Christian record. That said, archaeology at the Hill of Ward has found evidence of repeated burning and large-scale assembly over a long period, and the site now hosts a modern flame ceremony around which a contemporary festival has grown.

What is genuinely ancient about Samhain?

Ronald Hutton’s history of the British and Irish ritual year, The Stations of the Sun, is the standard scholarly reference for sorting the layers, with its chapters on Samhain, on the saints and souls, and on the modern Hallowe’en. Its conclusions can be set out plainly.

The festival was real. Samhain was a genuine pre-Christian seasonal marker, acknowledged as such in every medieval text that names it, a pastoral festival of communal gathering at the turn between the summer and winter halves of the year.

There is no good evidence it was a festival of the dead. Hutton finds that evidence wanting. The Christian feasts of All Saints and All Souls cluster around 1 and 2 November but derive from continental ecclesiastical practice; the date was fixed in German dioceses before it reached the Celtic lands, and in Ireland the church had used 20 April for its feast of martyrs. The older argument that the November date came from Celtic influence, Hutton concludes, breaks down.

The Celtic New Year claim is unfounded. It rested on a Victorian reading of late Manx folklore. The only surviving pre-Christian Gaelic calendar, found at Coligny in Gaul, appears to begin in summer, and no medieval Irish text names 1 November as the year’s start. The opening of Emer’s seasonal sequence at Samhain invites the inference but does not amount to explicit ancient testimony.

What Hutton does accept as likely ancient is that Samhain was a particularly numinous time when supernatural forces were felt to be unusually active, that the medieval literary tradition treats it consistently as a moment of otherworldly access, and that it was a real festival of seasonal transition.

The later folk customs

By the nineteenth and early twentieth centuries Samhain had become a rich node in the Irish folk calendar. It is described in Kevin Danaher’s survey of Irish calendar customs, the standard named ethnographic account, and in the Dúchas Schools’ Collection, gathered from schoolchildren in the late 1930s.

The Mayo material in that collection is direct and local. From Ballyglass in Co. Mayo, the collector May Joyce recorded that the direction of the wind on November’s night foretold the year’s weather, that rising river water meant provisions would be dear, that boys took cabbage and broke it against walls, and that people made a fortune-telling bread with a ring hidden inside it. She noted too that the old people said the souls travelled abroad on that night, and bread and milk were left on the table for them, and that a girl would peel an apple in one continuous strip, throw it over her head, and read the initial of a future spouse in its fall.

Across Ireland the documented customs include guising, when men visited households in disguise, recited verses, and expected food or played mischief, the direct ancestor of trick-or-treating; apple-bobbing; the fortune-telling barmbrack, in which a ring meant marriage and a coin meant prosperity; nut-burning divination; turnip lanterns carved with grotesque faces; and the setting of food by the fire for the returning dead.

The púca claimed particular dominion at this turn of the year. In folklore reported by Henry Morris, after Oíche Shamhna the púca went abroad and spoiled the blackberries, so that any berry picked after that night was held to be befouled. More widely, farmers left the last stalks of the harvest as the púca’s share, and to withhold it was to invite damage or barren soil. That bargain of gift or mischief echoes the trick-or-treat exchange.

How Samhain became Halloween

The decisive migration of these customs came with the mass emigration of Irish and Scottish people in the nineteenth century, above all after the Famine. Guising, turnip lanterns, the fortune-telling bread, and the atmosphere of Oíche Shamhna travelled to North America, where the more carveable pumpkin replaced the turnip and commercial industries amplified the costume and confectionery traditions. By Hutton’s account, every traceable modern Halloween custom descends from this Irish and Scottish folk inheritance, then re-exported around the world. The contemporary Irish Halloween, with its pumpkins, elaborate costumes, and formalised trick-or-treat, is in significant part a re-import: Irish custom travelled west, was transformed, and came home.

Modern Ireland has consciously recovered the inheritance through two major events. The civic Halloween festival in Derry has run since 1986, when the city council formalised a costume tradition that had begun spontaneously in the early 1980s; it describes itself as Europe’s largest Halloween festival and drew well over a hundred thousand visitors in 2019. The Púca Festival, inaugurated in 2019 in Athboy and Trim in Co. Meath, was built on Athboy’s existing flame ceremony and is sited in the landscape of the Hill of Ward, Trim Castle, and the Boyne Valley. It takes its name from the shape-shifting spirit of Irish folklore and runs across several nights of Halloween week.

Samhain in Connacht

The primary mythological anchor for Connacht is Cruachan, now Rathcroghan in Co. Roscommon, the royal site of Echtra Nerai, where the cave of Oweynagat is the opened mound that the Book of Leinster calls Ireland’s gate to the underworld. Rathcroghan takes in some two hundred and forty recorded archaeological sites and is one of the largest unexcavated royal complexes in Europe. Co. Mayo adjoins Roscommon within the same province, and the Dúchas material shows the folk customs alive and continuous in Mayo within living memory of the late-1930s collection. The Connacht setting is not peripheral to the Samhain story; it is where the myth is most specifically grounded.
