Beltane, known as Bealtaine in Irish, is the traditional Gaelic festival associated with the beginning of summer.
Celebrated around 1 May, Bealtaine marked an important transition in the traditional seasonal year. For farming communities, it was closely connected with livestock, summer grazing, protection and prosperity. Fire became one of the festival’s most memorable elements, with historical and folkloric sources describing bonfires and customs intended to protect cattle as they entered the summer season.
Today, Beltane is often presented as an ancient “Celtic fire festival”. There is truth behind that description, but the history is more interesting—and more complicated—than many modern retellings suggest.
To understand where Bealtaine fits alongside Samhain, Imbolc and Lughnasa, explore our Gaelic calendar guide to Ireland’s traditional seasonal year.
What Is Beltane?
Beltane is the English-language form commonly used for the traditional Gaelic festival of Bealtaine.
In modern Irish:
Bealtaine — May
Lá Bealtaine — May Day
Historically, Bealtaine marked the beginning of the summer half of the year.
This can seem strange if you’re accustomed to thinking of summer as beginning in June. But the traditional Gaelic seasonal cycle did not divide the year in exactly the same way as our modern astronomical or meteorological seasons.
For communities whose lives revolved around agriculture and livestock, early May represented a very real seasonal change.
Beltane or Bealtaine: Which Is Correct?
Both forms are encountered, but they appear in different contexts.
Bealtaine is the modern Irish form and the Irish word for May.
Beltane is a common anglicised spelling, particularly in English-language discussions of the historical festival and modern celebrations.
In Scottish Gaelic, you’ll encounter the related form Bealltainn.
Because this article focuses primarily on the Irish tradition, we’ll generally use Bealtaine when discussing Ireland historically and linguistically, while recognising that many people search for the festival as Beltane.
When Is Beltane Celebrated?
Bealtaine is traditionally associated with 1 May.
It marks the transition into the summer half of the traditional Gaelic year.
Rather than thinking of the festival as one isolated celebration, however, it helps to place it within a wider seasonal cycle:
Imbolc — beginning of spring
Bealtaine — beginning of summer
Lughnasa — beginning of the harvest season
Samhain — beginning of winter
These four festivals are commonly used to describe the traditional Gaelic calendar and the major transitions within the agricultural year.
The precise importance and customs associated with each festival varied across time and place.
Why Was Fire Important at Bealtaine?
Fire is one of the strongest traditions associated with Bealtaine.
Historical and folkloric accounts describe bonfires being lit around May Day, sometimes in connection with cattle and protective customs.
Fire could carry associations with:
- protection
- purification
- prosperity
- livestock health
- seasonal transition
One particularly well-known tradition involved cattle passing between or near fires before being moved to summer grazing.
The intention was protective: to safeguard valuable animals as they entered a new stage of the agricultural year.
Did People Really Drive Cattle Between Beltane Fires?
There is historical evidence connecting Bealtaine fires with cattle.
One important medieval reference appears in the early Irish glossary Sanas Cormaic, or Cormac’s Glossary, which associates Beltaine with fires and describes cattle being driven between them as protection against disease.
That makes the fire-and-cattle connection much more than a modern invention.
However, we should be careful about imagining one perfectly standardised ritual practised identically throughout Ireland for thousands of years.
Seasonal customs varied enormously.
Different communities could preserve, modify or abandon traditions over time.
It is more accurate to speak of a tradition of Bealtaine fire customs than one universal Beltane ceremony.
The Beltane Fire at Uisneach
One place has become particularly associated with Bealtaine fire traditions: the Hill of Uisneach in County Westmeath.
Uisneach is an important archaeological and mythological landscape and was regarded in medieval Irish tradition as a significant centre of Ireland.
Later traditions associate the hill with great assemblies and seasonal fires.
Today, Uisneach is again strongly connected with Bealtaine celebrations.
It is tempting to draw a perfectly straight line between modern events and ancient ceremonies, but historical continuity is rarely that simple.
The site’s importance is real.
Its association with Irish tradition is real.
But modern festival practices should not automatically be treated as exact reconstructions of rituals performed there in pre-Christian Ireland.
Was Beltane an Ancient Celtic Fire Festival?
Calling Bealtaine a Celtic fire festival is broadly understandable, but it can obscure important details.
“Celtic” covers several different languages, regions and historical cultures.
The Bealtaine tradition discussed here belongs specifically to the Gaelic world, particularly Ireland and Scotland.
Related May customs existed elsewhere, but that doesn’t mean every Celtic-speaking society celebrated one identical Beltane festival.
It is usually more accurate to describe Bealtaine as a traditional Gaelic seasonal festival.
Bealtaine and the Beginning of Summer
To understand the festival properly, think less about abstract symbolism and more about everyday rural life.
Summer meant changes in:
grazing
livestock management
milk production
crop growth
weather
household food supplies
Moving cattle into summer pasture could represent a major moment in the year.
Protecting those animals mattered enormously.
Many customs that can look purely ritualistic today make considerably more sense when placed in this agricultural context.
Bealtaine was about entering summer safely and prosperously.
Fire as Protection
In traditional societies, fire could carry powerful protective associations.
At Bealtaine, this could relate particularly to livestock.
But fire was only one element in a much wider collection of May customs.
People also used:
- flowers
- greenery
- decorated branches
- household precautions
- charms
- rituals involving water or dew
Together, these traditions reflect the sense that the beginning of May was a significant threshold.
Crossing that threshold successfully mattered.
The May Bush
One of Ireland’s most distinctive May traditions is the May Bush.
A branch or small tree could be decorated with objects such as:
- flowers
- ribbons
- coloured materials
- shells
- eggshells
The exact decorations and practices varied by region.
In some communities the May Bush belonged to an individual household. Elsewhere, it could become part of a wider community celebration.
The custom demonstrates that Bealtaine wasn’t solely a fire festival.
Greenery, flowers and visible signs of the changing landscape were equally important parts of May tradition.
May Flowers and Protection
Flowers were frequently associated with May Day.
Yellow spring flowers were particularly prominent in some traditions and might be placed around:
doors
windows
farm buildings
cattle
These decorations could carry protective significance.
They also visibly brought the changing season into the household.
This combination of beauty and protection is common in traditional customs: something decorative can simultaneously carry symbolic or supernatural meaning.
Bealtaine and Milk
Dairy appears repeatedly in Irish May folklore.
This makes sense once you understand how valuable milk and butter were to rural households.
Traditions sometimes expressed anxiety about another person—or a supernatural force—interfering with a household’s milk or butter production.
People therefore observed customs intended to protect their dairy prosperity.
To modern readers, these beliefs can sound unusual.
But beneath them lies a very practical concern:
If your cattle and milk production failed, your household could face serious economic consequences.
Folklore reflects what people cared about.
May Morning Dew
Another tradition associated with the first morning of May involves dew.
Folklore records beliefs that washing the face in May morning dew could promote beauty, health or good fortune.
Again, this reflects the special significance attached to transitional moments.
Ordinary things—water, flowers, fire—could acquire unusual power when encountered at a meaningful point in the seasonal year.
May morning was one such moment.
Beltane and the Aos Sí
Bealtaine also became associated with beliefs concerning supernatural beings, particularly the Aos Sí.
Seasonal transitions could be regarded as times requiring additional caution and protection.
This helps explain some of the protective customs surrounding:
- cattle
- houses
- milk
- fire
- flowers
You’ll sometimes see this described today as a moment when “the veil between worlds was thin.”
That phrase is common in modern spiritual writing, but it shouldn’t automatically be presented as an ancient Irish formulation.
A more historically cautious description is that Bealtaine was a liminal seasonal period associated with supernatural danger and protective customs.
Beltane and Samhain
Bealtaine makes particularly good sense when compared with Samhain.
They sit opposite one another in the traditional seasonal cycle.
Bealtaine opens the summer half of the year.
Samhain opens the winter half.
One points toward growth, grazing and summer.
The other points toward winter and the completion of the agricultural cycle.
Both became associated with strong traditions concerning seasonal transition and the supernatural.
Together, they illustrate how the Gaelic year was organised around changes that mattered to agricultural communities.
What About Imbolc and Lughnasa?
Imbolc and Lughnasa complete the four-part seasonal pattern commonly used today.
Imbolc — associated with early spring and the beginning of the agricultural year’s renewal.
Bealtaine — associated with summer’s beginning and livestock.
Lughnasa — associated with harvest, gatherings and late summer.
Samhain — associated with winter’s beginning.
The four festivals should not necessarily be imagined as four identical celebrations spaced neatly through an ancient calendar.
Their customs, evidence and importance differ.
But together they provide a useful framework for exploring Ireland’s traditional Gaelic calendar.
Is Beltane Pagan?
Bealtaine has pre-Christian roots.
But describing every recorded Bealtaine tradition simply as pagan can be misleading.
Much of the folklore we know was recorded from communities that had been Christian for many centuries.
Seasonal customs could coexist with:
- Christian prayer
- saints’ traditions
- holy wells
- church observance
- local folk belief
Traditions evolve.
An old seasonal custom does not have to remain unchanged for centuries to remain culturally meaningful.
So rather than attempting to classify every Bealtaine practice as either purely pagan or purely Christian, it is often more useful to examine when and where a particular custom was recorded.
Did Druids Celebrate Beltane?
This is an area where modern popular accounts often go beyond the evidence.
Druids certainly existed within ancient Celtic societies, and fire had ritual significance in various contexts.
But detailed descriptions of Druids performing the elaborate modern Beltane ceremonies sometimes presented online are much harder to substantiate.
We do not possess an ancient Irish instruction manual describing exactly how Druids celebrated Bealtaine.
That doesn’t mean the festival lacked pre-Christian ritual significance.
It means we should distinguish between:
what historical sources actually tell us
and
later reconstruction or modern interpretation.
Does Beltane Mean “Bel’s Fire”?
You will frequently encounter the claim that Beltane means “Bel’s fire” and was named for a Celtic god called Bel or Belenus.
That explanation is popular, but the etymology is not sufficiently certain to present it as settled fact.
The historical development of the word is debated.
Fire is unquestionably associated with Bealtaine traditions.
That does not automatically prove that the festival’s name literally means “Bel’s fire”.
When discussing ancient language, a plausible story is not the same thing as a demonstrated etymology.
Beltane Feasts
Food and communal gathering naturally formed part of seasonal celebrations.
However, the idea of one standardised ancient “Beltane feast” with a fixed traditional menu should be approached cautiously.
Historical rural communities ate according to:
- season
- region
- household wealth
- available livestock
- stored food
- local agricultural conditions
Modern Beltane celebrations may feature elaborate communal meals inspired by seasonal ingredients.
Those can be meaningful modern traditions without needing to be presented as exact recreations of an ancient Irish feast.
Beltane Bonfires Today
Bonfires remain one of the most visually powerful ways modern communities evoke Bealtaine.
Contemporary celebrations can include:
- fire ceremonies
- music
- storytelling
- dance
- historical interpretation
- seasonal food
- community gatherings
Some deliberately draw inspiration from historical sources.
Others combine folklore with modern spiritual or cultural practice.
The important distinction is between revival and unbroken historical continuity.
A revived tradition can still have cultural value.
It simply needs to be described accurately.
Beltane in Modern Paganism
Beltane has become an important festival in several modern Pagan and Neopagan traditions.
Modern celebrations may emphasise:
- fertility
- sexuality
- creativity
- fire
- nature
- seasonal renewal
- relationships
- personal transformation
These practices can draw inspiration from historical Bealtaine while also incorporating much newer ideas.
Modern Pagan Beltane is therefore best understood as a living contemporary tradition influenced by older seasonal material, rather than a perfect reconstruction of one ancient Irish ceremony.
Beltane in Ireland Today
In modern Ireland, Bealtaine remains first and foremost the Irish word for May.
Historical May customs survive through folklore, heritage projects and local traditions, while contemporary events have revived interest in the festival.
The name also appears in modern cultural contexts unrelated to ancient ritual.
This is part of what makes Bealtaine interesting.
It isn’t a forgotten word excavated from the distant past.
It still belongs to Gaeilge.
Useful Irish Words Connected With Bealtaine
If you’re exploring the festival through Irish, here are some useful words:
Bealtaine — May

tine — fire
tine chnámh — bonfire
samhradh — summer
bláth — flower
bó — cow
bainne — milk
im — butter

The vocabulary itself tells you something about the festival’s traditional world: fire, summer, flowers, livestock and seasonal celebration.
How to Celebrate Bealtaine Respectfully Today
You don’t need to recreate an imagined ancient ceremony to mark Bealtaine.
You might simply:
learn some seasonal Gaeilge
explore folklore from your own county
decorate a May branch
visit an Irish heritage site
learn about traditional May customs
spend time outdoors noticing the seasonal change
attend a cultural celebration
read about Ireland’s other seasonal festivals
Historical traditions are often more interesting when we engage with what is actually known rather than filling every gap with invented certainty.

Final Thoughts
The Beltane fire tradition gives us a glimpse into a world where the beginning of summer had enormous practical importance.
Cattle represented wealth.
Milk and butter sustained households.
Summer grazing mattered.
And seasonal change could bring both opportunity and danger.
Fire became one way of marking and protecting that transition.
Around it developed traditions involving flowers, May Bushes, dew, livestock and supernatural belief.
Some customs are documented historically.
Others have changed, disappeared or been revived.
And modern Beltane celebrations continue to reinterpret the festival again.
Behind all of them sits one remarkably persistent idea:
Bealtaine marks the arrival of summer.
