Today, November 11th, is Celtic Faerie Day, aka Lunantisidhe Day (Lunantisidhe means “moon fairy” and is sometimes found spelled Lunantishee). Believed to be the guardians of Sloes (that is, Blackthorn trees and their berries)—which are sacred in many Celtic Traditions—these faeries care for the Blackthorn plants and protect them against those who would do them harm.
November 11th (as well as May the 11th) is a day to honor not only the Lunantisidhe but also the Blackthorn itself. On these two days, no one may forage from the trees nor cut them. Anyone who does so will have misfortune befall them.
Like most Sidhe, the Lunantisidhe have a dual nature—they can be helpful or mischievous. To that end, there is a tradition of leaving offerings (especially for those with Blackthorn on their property) out on your windowsill, on your doorstep, or somewhere outside for the Lunantisidhe on the 11th of November (and 11th of May) to avert any mischief or bad behavior on the part of the faeries. It’s said that not only will this ward off their negative acts, but the Lunantisidhe might also offer you blessings.
Traditional offerings are milk, butter, honey, ale, or cakes. But other sweets are acceptable, as are blackberries, daisies, and even gemstones.
Like other Celtic sacred trees, Blackthorn has its own lore and magical uses. Some say it is the most sinister of the bunch, though, as it was known as “Straif” in ancient times, which is believed to be the origin of the word “strife.” Despite that (or maybe partially because of it), Blackthorn is very often associated with the concept of hope among devastation and of overcoming obstacles to move on to a better future.
Stories tell of certain Witches and Mages who would carry staves made of Blackthorn because something made from the word was known for having great magical power. Other stories say that a staff or rod made from Blackthorn wood is good as a divining rod, a wish granter, or a form of protection from evil. And, interestingly enough, Irish shillelaghs were traditionally made from the wood of the Blackthorn. The shillelagh, of course, is a club-like walking stick that was originally used as a weapon when settling a score, but has morphed over the centuries into a symbol of Irish heritage.
So, today, let’s give a quick thought (and maybe a sweet or two) for the Lunantisidhe and the Blackthorn. Who knows, maybe you’ll get lucky and find a blessing at your front door.
