St. Brigid, the Grain Goddess
In Ireland, this holy day is called Imbolc and begins at sunset on February 1 continuing through sunset February 2nd. There are several different derivations offered for the name Imbolc: from Ol-melc (ewe's milk) because the ewes are lactating at this time, from Im-bolg (around the belly) in honor of the swelling belly of the earth goddess, and from folcaim (I wash) because of the rites of purification which took place at this time. All of these explanations capture the themes of this festival.
February 1st is the feast day of St. Brigid, who began her life as a pagan goddess and ended up a Christian saint. She was a fire and fertility goddess. In her temple at Kildare, vestal virgins tended an eternal fire. On her feast day, her statue was washed in the sea (purification) and then carried in a cart through the fields surrounded by candles.
The legends about the goddess, Brigid, gradually became associated with (the somewhat spurious) Saint Brigid who founded the first convent in Ireland (where else?) at Kildare.
To celebrate St. Brigid's day, people put out a loaf of bread on the windowsill for the Saint and an ear of corn for her white cow, offerings for the grain goddess like the loaf buried in the first furrow. A small quantity of special seeds are mixed with those to be sown. Wheat stalks are woven into X-shaped crosses to serve as charms to protect home from fire and lightning.
In the Highlands, women dress the corn doll or last sheaf (from Lammas or the autumn equinox) in a bridal gown and put her in a basket, which is called the Bride's bed. A wand, candle or other phallic object is laid across her and Bride is invited to come, for her bed is ready.
