A priest of Demeter once told us that the grain must die so the people may live. He meant it literally. The autumn equinox is the hinge of that death: the moment when day and night stand equal before the dark half of the year takes its hold. The autumn equinox (Mabon in modern Pagan tradition) marks the second harvest, the astronomical beginning of fall, and a ritual pause to honor balance before descent. The sun crosses the celestial equator on this day, usually September 22 or 23, and from that instant the nights grow longer than the days.
We keep a small bowl of dried apples and acorns on the library’s reading table from the equinox until Samhain. The smell changes as the weeks pass. That is the point.
Where Does the Name “Mabon” Come From?
The name “Mabon” for the autumn equinox is a modern invention, and we should say so plainly. It was popularized in the 1970s by Aidan Kelly, a founder of the Covenant of the Goddess, who assigned Welsh mythological figures to the solstices and equinoxes to give the emerging Neopagan Wheel of the Year a cohesive structure. Mabon ap Modron (the Divine Son of the Divine Mother) appears in the Welsh Mabinogion as a prisoner freed by King Arthur’s men. He has no historical connection to harvest festivals.
The older names are better. In Anglo-Saxon tradition, the equinox was Hærfestmōnaþ (Harvest Month). In Irish Gaelic, Meán Fómhair (Middle of Harvest). In Scottish Gaelic, An t-Sultain (the Time of Plenty). The Norse called it Haustblót (Autumn Sacrifice). Each of these names points to the same truth: this was a time of killing and thanking.
The History of the Autumn Equinox: What Our Ancestors Actually Did
The archaeological record shows that the autumn equinox was observed long before any written tradition named it. Newgrange in Ireland, built around 3200 BCE, aligns with the winter solstice, not the equinox. But the passage tombs of Loughcrew (also Ireland, circa 3300 BCE) catch the sunrise of both equinoxes. The chamber at Cairn T fills with light on March 21 and September 23. Someone carved that alignment into stone five thousand years ago. They wanted the light to touch the bones on those two days.
The Greek and Roman Harvests
The classical world held its harvest rites at the equinox. The Thesmophoria, a Greek festival for Demeter and Persephone, was celebrated in October (the Attic month Pyanepsion), but its logic belongs to the equinox. Women built shelters of branches, fasted, and buried pig carcasses in pits to rot. The decayed remains were later mixed with seed grain to ensure fertility. This was not symbolic. The pig flesh was actual fertilizer, and the ritual was actual farming.
The Romans celebrated the Consualia on August 21 and again on December 15, but their true harvest festival was the Meditrinalia on October 11, when new wine was tasted and old wine was offered to Jupiter. The pattern is consistent: you do not celebrate the harvest until the grain is actually in the barn.
The Celtic and Germanic Evidence
The Celts divided the year into two halves: light (Samhain to Beltane) and dark (Beltane to Samhain). The equinoxes and solstices were not their primary festivals. The four great Celtic fire festivals (Samhain, Imbolc, Beltane, Lughnasadh) fall at the midpoints between the solar events. But the equinox was still marked. At Tara, the Feis Temro (Feast of Tara) was held at the equinox, when the king ritually married the land goddess. The Norse Haustblót was a sacrifice of the first animals, offered to Odin and the dísir (ancestral mothers) to secure the herd’s survival through winter.
What these traditions share is not a name but an action: you kill something, you thank something, and you store what remains.
What the Autumn Equinox Symbolizes
The symbol of the equinox is the scale. Day and night balanced, but only for a moment. The Norse myth of the god Baldr dying and descending to Hel is sometimes recited at this time. The Greek myth of Persephone returning to the underworld is the more common parallel. She eats six pomegranate seeds in Hades, and for each seed she must spend one month in the dark. The equinox is the day she swallows the first.
But the older symbol is the apple. Cut an apple crosswise through the equator and you reveal a five-pointed star, each point holding a seed. The apple is the fruit of knowledge, of immortality, of the Otherworld in Celtic tradition. Avalon (Ynys Afallon, the Isle of Apples) is where King Arthur was taken to heal. The apple’s five-pointed star is the same shape the Pythagoreans called the pentemychos, the five-chambered womb of creation. To cut an apple at the equinox is to see the geometry of balance.
The colors of the season are rust, gold, brown, and deep red. They are not decorative. They are the colors of dying leaves, dried blood, and stored grain.
Practices and Traditions: What We Actually Do
The practices of the autumn equinox fall into three categories: thanksgiving, preparation, and release. We do not invent these. We recover them.
The Harvest Meal
The simplest practice is the harvest meal. In medieval Ireland, the Céilí of the harvest was a communal feast where the first sheaf of grain was made into a doll (the Cailleach, the Old Woman) and kept until spring. The meal itself was the ritual: fresh bread, the first apples, the slaughtered animal that could not be fed through winter. We light ours in a fireproof bowl on the balcony, but the logic is the same. You eat what you have, and you acknowledge that it came from something that died.
The Balance Ritual
Some traditions mark the equinox by naming what must be released. The Norse Haustblót involved sacrificing a goat or sheep, but the modern equivalent is a written list of what you are ready to let die: a habit, a grievance, a project that will not finish. The list is burned. The smoke carries it. This is not therapy. It is the same logic as the Greek pharmakos, the scapegoat who carried the community’s sins out of the city. You cannot enter the dark half of the year carrying what belongs to the light.
The Apple Offering
We leave a single apple on the windowsill from equinox to Samhain. It is an offering to the ancestors, who are said to walk more freely as the veil thins. The apple shrivels over the six weeks. By Samhain it is a leathery husk. We bury it then. If you have never watched an apple dry from the inside out over a month and a half, you have missed a small education in mortality.
How the Autumn Equinox Differs from Other Harvest Festivals
The autumn equinox is often confused with Lughnasadh (August 1) and Samhain (November 1). They are not the same.
Lughnasadh is the first harvest, the grain harvest. It is named for the god Lugh, who held funeral games for his foster mother Tailtiu, who died clearing the plains of Ireland for agriculture. It is a festival of athletic competition, matchmaking, and the first cutting of the corn. The equinox is the second harvest: the fruit harvest, the grape harvest, the slaughter of the fattened animals.
Samhain is the third harvest, the meat harvest, and the beginning of the Celtic new year. It is the night when the cattle were culled and the ancestors were fed. The equinox is a preparation for Samhain. You take stock. You balance the accounts. You do not yet open the door to the dead.
The equinox is the pause between the two. It is the breath before the scream.
Common Misconceptions About the Autumn Equinox
“Mabon is an ancient Celtic festival.” It is not. The name was coined in the 1970s. The practices are ancient. The name is not.
“The equinox is the only day when day and night are equal.” This is nearly true but not exact. The word equinox means “equal night,” but the actual balance of light and dark occurs a few days before or after the equinox, depending on your latitude, because of how the atmosphere refracts sunlight. The moment is approximate. The symbol is what matters.
“All Pagans celebrate the equinox the same way.” They do not. Wiccan traditions often follow the Wheel of the Year as codified by Gerald Gardner and later expanded by Aidan Kelly. Reconstructionist traditions (Celtic, Norse, Hellenic) follow the primary sources of their respective cultures. Some celebrate. Some fast. Some do nothing at all.
“The equinox is about balance.” It is about balance, but balance is not peace. Balance is tension. The scale holds two weights that are equal. It does not hold two weights that are comfortable.
