Imbolc, also called Saint Brigid's Day, is a traditional Gaelic festival celebrated on February 1. It marks the start of spring and is the feast day of Saint Brigid, Ireland's patron saint. In the past, this festival was widely observed in Ireland, Scotland, and the Isle of Man. Imbolc happens about halfway between the winter solstice and the spring equinox. It is one of four Gaelic seasonal festivals, along with Bealtaine, Lughnasadh, and Samhain.
Imbolc is mentioned in early Irish writings, though less frequently than other festivals. Historians believe it began as a pre-Christian (or pagan) celebration linked to the lambing season, the arrival of spring, and possibly the goddess Brigid. Over time, the festival may have been adapted to honor Saint Brigid instead. A feast for Saint Brigid was first recorded in the Middle Ages, but detailed descriptions of its customs appeared later. In recent centuries, people have woven Brigid's crosses on Saint Brigid's Day and placed them over doors and windows to protect against fire, illness, and harm. A doll of Brigid, called a Brídeóg, was made and carried through communities by girls, sometimes with the help of "strawboys." It was believed that Saint Brigid visited homes on the night before her feast day. To welcome her, people prepared a bed, left food and drink, and placed clothing outside for her to bless. Holy wells were visited, a special meal was shared, and the day was connected to weather predictions.
Many traditions from Imbolc faded in the 20th century, but some Christians still observe it as a religious holiday, and others celebrate it as a cultural event. Since the late 20th century, groups like Celtic neopagans and Wiccans have also honored Imbolc as a religious festival. Since 2023, "Imbolc/St Brigid's Day" has been an official public holiday in Ireland.
Name
The origin of the word Imbolc or Imbolg is not fully understood. One common idea is that it comes from the Old Irish phrase i mbolc (Modern Irish: i mbolg), which means "in the belly" and refers to the time when ewes are pregnant. Joseph Vendryes suggested it comes from the Old Irish imb- (a prefix meaning "intensive") and folc ("wash, cleanse"), connecting it to the verb folcaim ("to wash or cleanse oneself") and suggesting it might relate to a ritual of cleaning. Eric P. Hamp linked it to a Proto-Indo-European root that also means "milk" and "cleansing." In the early 10th century, Cormac's Glossary mentions Oímelc, describing it as the start of spring and deriving it from oí-melg ("ewe milk"), explaining it as "the time when sheep's milk appears." However, linguists believe this explanation is not accurate, as it appears to be a later attempt to make the word's meaning clearer.
The 12th century Book of Leinster version of the Táin Bó Cúailnge ("Cattle Raid of Cooley") states that Imbolc (spelled imolg and imbuilg) occurs three months after the 1 November festival of Samhain. In a 14th century version of the same text, the Stowe manuscript, the name is changed to Fél Brigde ("St. Brigid's Feast"), suggesting that St. Brigid's Day may have replaced or combined with Imbolc.
An Old Irish poem in the Metrical Dindshenchas about the Táin mentions: "iar n-imbulc, ba garb a ngeilt", which Edward Gwynn translated as "after Candlemas, rough was their herding." Candlemas is a Christian holiday celebrated on 2 February, known in Irish as Lá Fhéile Muire na gCoinneal ("feast day of Mary of the Candles").
In a 17th century version of the story Agallamh na Seanórach, Imbolc is spelled Iomfhoilcc. Peter O'Connell's Irish-English dictionary from 1843 connects Oimelc or Imbulc to Féil Brighde, the Feast of Saint Brigid.
Origins
Historians such as Ronald Hutton and Dáithí Ó hÓgáin believe that Imbolc likely began before Christianity. Some say Imbolc marked the time when sheep gave birth, when fresh milk became available after a period of food shortages, and when people started preparing for planting crops in the spring. Scholars Joseph Vendryes and Christian-Joseph Guyonvarc'h suggest Imbolc may also have been a festival for cleaning or renewal, similar to the ancient Roman festivals Februa or Lupercalia, which happened around the same time of year.
Some experts think Imbolc was important in Ireland since ancient times. A few tombs in Ireland are aligned with the sunrise near the time of Imbolc and Samhain. These include the Mound of the Hostages on the Hill of Tara and Cairn L at Slieve na Calliagh. Frank Prendergast argues that such alignments are so rare that they may be a coincidence.
Hutton writes that Imbolc was important enough for its date to later be connected to Saint Brigid, known as the "Mother Saint of Ireland." A writer named Cogitosus, who lived in the late 7th century, was the first to mention a feast day for Saint Brigid being celebrated in Kildare on February 1. Saint Brigid is believed to have lived in the 6th century and founded the important monastery of Kildare. She became the center of a major religious movement. However, The Oxford Dictionary of Saints notes that few historical facts about her are known, and early stories about her are mostly anecdotes or miracle tales linked to Irish pagan traditions. Some authors suggest that Saint Brigid may have been based on the goddess Brigid or that she was a real person, with stories about the goddess later added to her. Both the saint and the goddess are connected to wisdom, poetry, healing, protection, blacksmithing, and domesticated animals, according to Cormac's Glossary and Lebor Gabála Érenn. Imbolc, which celebrates the start of lambing, may have been linked to Brigid as a fertility goddess. Hutton suggests that the goddess may have already been connected to Imbolc, and this connection was continued by making it Saint Brigid’s feast day (a practice called Interpretatio Christiana). Alternatively, Imbolc’s association with milk may have drawn Saint Brigid to it, because of a legend that she was the wet-nurse of Jesus Christ.
Prominent folklorist Seán Ó Súilleabháin wrote: "The main significance of the Feast of St. Brigid seems to be that it was a Christian version of an important time in Ireland’s farming year—the beginning of preparations for planting crops in the spring. Every part of the saint’s worship (or the worship of the goddess she replaced) is connected in some way to food production."
Historical customs
The festival of Imbolc is mentioned in several early Irish manuscripts, but they say very little about its original rites and customs. Imbolc was one of four main seasonal festivals in Gaelic Ireland, along with Beltane (1 May), Lughnasadh (1 August), and Samhain (1 November). A story called Tochmarc Emire, which was written in the 10th century, mentions Imbolc as one of four seasonal festivals and says it is "when the ewes are milked at spring's beginning." This connection between Imbolc and the arrival of lambs and sheep's milk likely reflected farming customs that ensured lambs were born before calves. In late winter or early spring, sheep could survive better than cows on the sparse vegetation, and farmers tried to resume milking as soon as possible because their food supplies were low. As a seasonal festival, the timing of Imbolc might have originally been more flexible and linked to the start of lambing and the blooming of blackthorn.
The Hibernica Minora includes an Old Irish poem about the four seasonal festivals. Translated by Kuno Meyer in 1894, it says, "Tasting of each food according to order, this is what is proper at Imbolc: washing the hands, the feet, the head." This suggests that ritual cleansing was part of the festival.
From the 18th century to the mid-20th century, many traditions of St. Brigid's Day were recorded by folklorists and writers. These records describe how the festival was celebrated and provide clues about how it might have been celebrated in the past.
In Ireland, Brigid's crosses are traditionally made on St. Brigid's Day. A Brigid's cross is usually made by weaving rushes into a four-armed equilateral cross, though some had three arms. They were hung over doors, windows, and stables to welcome Brigid and to protect against fire, lightning, illness, and evil spirits. The crosses were generally kept until the next St. Brigid's Day. In western Connacht, people made a Crios Bríde (Brigid's girdle), a large ring of rushes with a cross in the middle. Young boys would carry it around the village, inviting people to step through it and be blessed.
On St. Brigid's Eve, it was said that Brigid visited kind households and blessed the people. Brigid represented the light half of the year and the power that brought people from winter into spring, so her presence was important at this time.
Before going to bed, people would leave clothing or cloth outside for Brigid to bless. The next morning, these items were brought inside and believed to have healing and protective powers. Brigid was symbolically invited into the house, and a bed was often made for her. In Ulster, a family member representing Brigid would walk around the home three times with rushes, knock on the door three times, and ask to be let in. On the third attempt, they were welcomed in, a meal was shared, and the rushes were used to make crosses or a bed for Brigid. In 18th-century Mann, people would stand at the door with a bundle of rushes and say, "Brede, Brede, come to my house tonight. Open the door for Brede and let Brede come in." In County Donegal, the person sent to fetch rushes would kneel on the front step and say, "Go on your knees, open your eyes, and let in St. Brigid." Those inside would answer, "She's welcome." The rushes were then spread on the floor as a carpet or bed for Brigid. In the 19th century, some old Manx women would make a bed for Brigid in the barn with food, ale, and a candle on a table. The custom of making Brigid's bed was common in the Hebrides of Scotland, where it was recorded as early as the 17th century. A bed of hay or a basket-like cradle was made for Brigid. Someone would call out three times: "a Bhríd, a Bhríd, thig a stigh as gabh do leabaidh" ("Bríd, Bríd, come in; thy bed is ready"). A corn dolly called the dealbh Bríde (icon of Brigid) was placed in the bed, and a white wand, usually made of birch, was laid beside it. This represented the wand Brigid was said to use to make plants grow again. In some parts of the Hebrides, women would dance while holding a large cloth and call out, "Bridean, Bridean, thig an nall 's dean do leabaidh" ("Bríd, Bríd, come over and make your bed").
In the Outer Hebrides, ashes from the fire would be raked smooth, and in the morning, people would look for a mark in the ashes as a sign that Brigid had visited. If no mark was found, they believed bad fortune would come unless they buried a cockerel at the meeting of three streams as an offering and burned incense on their fire that night.
In Ireland and Scotland, a representation of Brigid was paraded around the community by girls and young women. This was usually a doll called a Brídeóg ("little Brigid"), also known as a "Breedhoge" or "Biddy" in English. It was made from rushes or reeds and decorated with cloth, flowers, or shells. In the Hebrides of Scotland, a bright shell or crystal called the reul-iuil Bríde (guiding star of Brigid) was placed on its chest. The girls would carry it in a procession while singing a hymn to Brigid. All wore white with their hair unbound as a symbol of purity and youth. They visited every house in the area, where they received either food or more decorations for the Brídeóg. Afterward, they feasted in a house with the Brídeóg placed in a place of honor and put it to bed with lullabies. When the meal was done, local young men humbly asked for admission, bowed to the Brídeóg, and joined the girls in dancing and merrymaking. In many places, only unwed girls could carry the Brídeóg, but in some areas, both boys and girls carried it.
In parts of Ireland, rather than carrying a Brídeóg, a girl would take on the role of Brigid. She would be escorted by other girls and go house
Present day customs
St Brigid's Day and Imbolc are celebrated by both Christians and non-Christians. Some people still make Brigid's crosses and Brídeog s or visit holy wells named after St Brigid on February 1. In Killorglin, County Kerry, parades honoring St Brigid have been held again each year as part of the "Biddy's Day Festival." During this event, men and women wear decorated straw hats and masks, visit public houses with a Brídeóg to protect against bad spirits and bring good luck. Other activities include folk music, talks about history, films, plays, and workshops on making crosses. The main event is a torchlight parade led by groups called "Biddy groups." Since 2009, a yearly "Brigid of Faughart Festival" has taken place in County Louth. This festival honors Brigid as both a saint and a goddess, includes a pilgrimage to Faughart, and features music, poetry, and lectures. In Derry, the "Imbolc International Music Festival" celebrates folk music during this time. In England, the village of Marsden holds a "Imbolc Fire Festival" every two years. This event includes lanterns, fire performances, music, fireworks, and a symbolic battle between characters representing the Green Man and Jack Frost.
In recent years, Irish embassies have hosted yearly events on St Brigid's Day to honor famous Irish women who live outside Ireland and to highlight their work in the arts. In 2022, Dublin held its first "Brigit Festival," which showcased the achievements of Irish women through exhibits, tours, lectures, films, and a concert.
In 2016, the Green Party suggested making St Brigid's Day a public holiday in Ireland. This became law in 2022 after the party joined the government, and "Imbolc/St Brigid's Day" has been a public holiday every year since 2023. This holiday marks both the saint's feast day and the seasonal festival. A government statement said it would be the first Irish public holiday named after a woman and that all four traditional Celtic seasonal festivals would now be public holidays. The holiday is observed on the first Monday in February, unless February 1 falls on a Friday, in which case the holiday is on that Friday instead.
Some Neopagans celebrate Imbolc or events based on Imbolc, though their practices vary. Some try to follow ancient traditions closely, while others use many sources for inspiration. These festivals usually happen near February 1 in the Northern Hemisphere and near August 1 in the Southern Hemisphere. Some Neopagans celebrate Imbolc at the midpoint between the winter solstice and spring equinox, which is usually February 3 or 4 in the Northern Hemisphere. Others use the full moon closest to this time. Some also use natural signs, like the appearance of certain plants, to decide when to celebrate.
Celtic Reconstructionists aim to rebuild ancient Celtic religious practices based on research and historical records. They may adapt traditions slightly for modern life but avoid mixing practices from different cultures. They use traditional songs and rituals from sources like The Silver Bough and The Carmina Gadelica. This time is for honoring the goddess Brigid, and many followers choose it for special rituals to her.
Wiccans and Neo-Druids celebrate Imbolc as one of the eight Sabbats in their yearly cycle, which follows Midwinter and comes before Ostara. In Wicca, Imbolc is often linked to the goddess Brigid and is sometimes considered a "women's holiday" with rituals only for female members of a group. For Dianic Wiccans, Imbolc is the traditional time for initiation ceremonies.
