The Lighting of the Balefire
The name “Beltane” has been traced back to an old Celtic word meaning “bright fire,” and is thought by some scholars to be related to the ancient Sun god Belenos, whose name has been translated as “bright shining one.” Belenos was worshipped throughout Celtic Europe and his feast day was on May 1st, so this connection seems logical, but is not universally accepted by historians.
For one thing, Belenos (also known as Bel or Beil) doesn’t make significant appearances in the mythology of the areas where Beltane was historically celebrated: Ireland, Scotland, and the Isle of Mann. In fact, he was much more significant to the Gaulish Celts of the European continent, where the May 1st festivals are known by different names. Nonetheless, the ritual importance of fire was a central focus of Beltane for the ancient Celts of the western-most islands, where the first references to the holiday are found.
The chief event at Beltane in ancient Ireland was the lighting of the balefire on the eve of May 1, the first fire of the light half of the Celtic year. In preparation for this event, every household hearth was extinguished.
Legend has it that tribal representatives from all over Ireland met at the hill of Uisneach, a sacred site where a giant bonfire was lit. Each representative would light a torch from the great fire, and carry it back to their village, where the people waited in the darkness. From the village torch, each household would then relight their home fires, so that all of Ireland was set alight from the same initial flame.
In another version of this story, the fire at Uisneach could be seen from several miles away in every direction, signaling to the surrounding villages to light their own central fires, which was then spread throughout their communities. Either way, this act marked the beginning of summer, with hopes for plentiful sunshine throughout the season.
As a living symbol of the Sun, ritual fire was clearly seen as having magical powers. In many Celtic areas, the Beltane fires were also used for ritual purification of cattle before they were turned out into the summer pastures. The cattle were driven between two large bonfires, which were tended by Druids who used special incantations to imbue the fires with sacred energy.
The fire would clear the animals of any lingering winter disease and protect them from illness and accidents throughout the summer. People would also walk between the fires, or jump over them, for luck and fertility through the coming year. In some areas, the ashes from the smoldering fire would be sprinkled over crops, livestock, and the people themselves.
Over time, the annual Beltane fires grew into larger festivals, where people came to greet each other after the long winter. Dancing, music, games and great feasts became traditions, along with a free license for sexual promiscuity on this special occasion. Other customs observed at this time included eating “Beltane bannock”—a special oatcake that bestowed an abundant growing season and protection of livestock—and making a “May Bush,” a branch or bough from a tree decorated with brightly colored ribbons, flowers, and egg shells.
People would dance around the May Bush on Beltane, and then either place it by the front door for luck or burn it in the bonfire. This was believed to be a remnant of Druidic tradition, which held many trees to be sacred and possess magical qualities. A related custom was hanging a rowan branch over the hearth or weaving it into the ceiling to protect the house for the coming year.
Trees, herbs and flowers in general played a part at Beltane and at other May Day celebrations throughout Europe. Primrose flowers and hawthorne and hazel blossoms were gathered and placed at doors and windows, made into garlands, and even used to adorn cattle. Yellow flowers were prized for their association with the Sun.
Herbs gathered on this day were said to be especially potent for magic and healing, especially if gathered at dawn or while the morning dew was still on them. The “May dew” inspired a variety of traditions around beauty. Young women would roll naked in the dew or collect it to wash their faces with, as it was said to purify the skin, maintain youthful looks and help attract a love partner.
