Bendithion Nos Galan Haf i bawb | Blessings of Summer’s Eve to all!
Calan Haf - the calends or start of summer. In the traditional Welsh calendar, this was considered the agricultural start of the summer period. Gone are the cold days of winter, now we enter into the time of year when the sun is at its strength. A time of joy and frivolity throughout history. Whilst nowadays we measure the start of this period with a calendar, it’s likely in the past a sure sign that the summer was near was when the hawthorn trees came into flower. This is a time of growth and power, and of course joy!
However, just as any liminal period of transition and shift, in Welsh myth and lore the eve of summer brought all manners of magic, mischief, and mayhem. The eve of summer is essentially a warmer weather Nos Galan Gaeaf / All Hallow’s Eve (Halloween). So as you can imagine, lore abounds regarding ghosts, spirits, fairies, and witches at this time.
Nos Galan Haf is one of our three “Ysbrydnos” or spirit nights here in Wales.
In the four branches of the Mabinogi it was at May’s Eve when Rhiannon’s child was both born and ultimately snatched away from her by a mysterious otherworldly claw. In Culhwch and Olwen we are told that Gwyn ap Nudd (who in later folklore became known as King of Fairy) battles every May Day with his rival Gwythyr ap Greidawl for the hand of Creiddylad. A battle that will continue for all eternity.
The eve of summer was also a time of heightened fairy activity. Upon this liminal night we might see them dancing in the heathland, the meadows, or forests. Careful not to be tempted or seduced to join them in their dance, however, for you may indeed find yourself dancing for an eternity.
This was a time when bonfires were lit, the flowers of the blossoming trees were utilised as decoration, and all manners of dances, merriment, and debauchery were carried out. So take that idea and celebrate this time of year with joyful abandon!
May the celebrations of your Nos Galan Mai, May Day, Witches’ Night, Beltane, or whatever this time might be in your culture or personal practice be inherently magical! I’ll catch some of you at the sabbath pyre soon 😉
