เครื่องรางกางเขนนักบุญบริจิดBrigid's crossCros Bhríde

The cross is woven on 1 February, the feast day of Brigid of Kildare and the date of Imbolc in pre-Christian Ireland, and hung from the rafters to bring the saint's blessing and protection for the rest of the year. The practice of making them is first attested in the seventeenth century.

Brigid herself left no historical record; she was born around 450 in Leinster, and almost everything about her comes from a hagiography written by the monk Cogitosus some two hundred years later. The story attached to the cross is a deathbed conversion: telling a pagan chieftain — in some versions her father — about the Crucifixion, Brigid gathered rushes from the floor and wove them into a cross, and the chieftain asked to be baptised. In another story she was handed a poisoned drink by a woman who meant her harm, and wove the cross to neutralise it.

The household version has a timetable. Families gathered rushes on 31 January. After the evening meal the head of the household supervised the rest of the family weaving, the finished crosses were left out overnight to receive Brigid's blessing, and on 1 February they went up in the main dwelling, the outhouses and the stables. Some households took the old ones down and replaced them each year; others let them accumulate between feasts. Discarded crosses were burned or buried, burial preferred, because of Brigid's associations with agriculture. The weaving was not confined to the feast: friends gave each other crosses to strengthen a bond, and newly married couples were given womb crosses to hang over the door, Brigid being a patron of fertility too. Outside Ireland, the crosses are hung in Glastonbury, on a local legend that Brigid visited the town in 488, and Irish families send them to relatives abroad or carry one when they leave.

The shape carries arguments. Some historians compare the central lozenge to the Mexican god's eye and to the Eurasian magic square. The swastika type, with its arms set at right angles off a central diamond, reads as a wheel in motion and may have originally stood for the sun; in parts of Ulster the same motion is made with three arms, which has been compared to the triskelion.

Its second life is national. After the Irish Free State gained independence in 1922 the cross became one of the motifs artists used to build a cultural identity separate from Britain's, alongside the shamrock and the harp. It went into the logo of the Irish Department of Health in the 1950s and, as of 2024, was still part of the logo of the Nursing and Midwifery Board of Ireland. It was chosen as the first station identification marker for Raidió Teilifís Éireann in 1962 — Alice Curtayne wrote that it was picked to evoke "the image of quiet, serene places in the springtime of our history, of rush-bordered rivers in a serene arcadian landscape" — survived nine redesigns, and was dropped in 1995 in favour of what the broadcaster called "a clean striking piece of modern design". Carol Coulter wrote in The Irish Times that Saint Brigid's cross had lost its place as a symbol of national identity, at least as far as the national broadcaster was concerned.

Gather rushes or straw on the eve of the feast, 31 January. Weave after the evening meal, the household together. Leave the crosses out overnight for the saint's blessing. Hang them on 1 February in the house, the outhouses and the stables. Take them down and replace them at the next feast, or leave them to accumulate. Retire by burning or, preferably, burying. The direction they were hung in is not recorded — but the centre is described as a lozenge rather than a square, which suggests the cross was displayed as a saltire rather than upright.

Still woven. The weaving declined through the twentieth century, partly because house renovations made the crosses hard to hang in the old way, and 1 February has since been declared a national holiday in Ireland. In 1942 the Irish Folklore Commission ran a questionnaire on the Feast of Saint Brigid and collected several hundred crosses; in 2022 twenty-one of them went on display at the National Museum of Ireland – Country Life in Castlebar.
