Happy Imbolc!

Tonight is the eve of Imbolc, the festival of the waxing light. Days are visibly longer. This is the midpoint between the winter solstice and the spring equinox.

Here is some information on the Celtic origin of Imbolc. The first link includes ways to celebrate. - Wicked Blue


Imbolc

Date: February 1st and/or 2nd

Other Names: Oimelc, Candlemas, St. Brigid's Day, St. Brigit's Day

Pronunciations: IM-blk

As with all Old Tradition observances, this holiday is usually celebrated beginning at sundown on February 1 and continuing through the day of February 2. Imbolc means in the belly of the Mother because that is where seeds are beginning to stir as it is Spring.

Another name for this holiday is Oimelc, meaning milk of ewes since it is also the traditional lambing season in the old world. Herd animals have either given birth to the first offspring of the year or their wombs are swollen and the milk of life is flowing into their teats and udders. It is the time of Blessing of the seeds and consecration of agricultural tools. It marks the center point of the dark half of the year.

This holiday is especially sacred to the Celtic Fire Goddess, Brigit, patron of smithcraft, healing, midwifery, and poetry. It is the festival of the Maiden, for from this day to March 21st, it is her season to prepare for growth and renewal. The Maiden is honored, as the Bride, on this Sabbat. Straw Brideo'gas (corn dollies) are created from oat or wheat straw and placed in baskets with white flower bedding. Young girls then carry the Brideo'gas door to door, and gifts are bestowed upon the image from each household. Afterwards at the traditional feast, the older women make special acorn wands for the dollies to hold, and in the morning the ashes in the hearth are examined to see if the magic wands left marks as a good omen. Brighid's Crosses are fashioned from wheat stalks and exchanged as symbols of protection and prosperity in the coming year. Home hearth fires are put out and re-lit, and a besom is place by the front door to symbolize sweeping out the old and welcoming the new. Candles are lit and placed in each room of the house to honor the re-birth of the Sun.

Fire Deities of the Celts
The two most popular deities of the ancient Celts were Brighid/Bride/Brigantia and Lugh/Lugus/Llew. Both were deities of brightness and fire. Lugh was not a Sun God as is popularly supposed; he represented brilliance in craft and in thinking and was called "master of every art." Similarly, Brighid was a Fire Goddess, mistress or patroness of arts. She was a Goddess of Healing, Smith Craft (a magical art in ancient times), and Poetry, and also a patroness of mothers (because to be a mother was to be a mistress of every art to at least a small extent).

Brighid was the Goddess invoked at Imbolc, the great Fire Festival of February 1 that celebrated the lactation of the ewes.
