Imbloc (Candlemass, Imblog, Imbole) - February 2nd
This holiday is also known as Candlemas, or Brigid's (pronounced BREED) Day. One of the 4 Celtic "Fire Festivals. Commemorates the changing of the Goddess from the Crone to the Maiden. Celebrates the first signs of Spring. Also called "Imbolc" (the old Celtic name).
This is the seasonal change where the first signs of spring and the return of the sun are noted, i.e. the first sprouting of leaves, the sprouting of the Crocus flowers etc. In other words, it is the festival commemorating the successful passing of winter and the beginning of the agricultural year. This Festival also marks the transition point of the threefold Goddess energies from those of Crone to Maiden.
It is the day that we celebrate the passing of Winter and make way for Spring. It is the day we honour the rebirth of the Sun and we may visualize the baby sun nursing from the Goddess's breast. It is also a day of celebrating the Celtic Goddess Brigid. Brigid is the Goddess of Poetry, Healing, Smithcraft, and Midwifery. If you can make it with your hands, Brigid rules it. She is a triple Goddess, so we honour her in all her aspects. This is a time for communing with her, and tending the lighting of her sacred flame. At this time of year, Wiccans will light multiple candles, white for Brigid, for the god usually yellow or red, to remind us of the passing of winter and the entrance into spring, the time of the Sun. This is a good time for initiations, be they into covens or self-initiations.
