🎆 Special Edition: New Year’s Eve: When Midnight Feels Haunted

Fairy Folk at Samhain: Offerings at the Threshold

There are autumn nights when I can almost feel them. The air stills, leaves skitter across the path, and I sense I am not entirely alone. I’ve always believed in fairies, though not the tiny winged ones of picture books. At Samhain, when the veil thins, I think of the Aos Sí — the “people of the mounds” — who were once both feared and honored across Ireland and Scotland. This was their season: a time when neighbors left offerings at thresholds, not only for their ancestors but also for the unseen folk who walked abroad.

Who Were the Aos Sí?

The Aos Sí (pronounced “ees shee”) were not quaint sprites but powerful beings tied to the ancient burial mounds, or sidhe, that dotted the Irish landscape. Some traditions remembered them as ancestral spirits. Others whispered they were older still — remnants of the Tuatha Dé Danann, the pre-Christian gods of Ireland, diminished but not gone. To many, they were simply the hidden neighbors: dangerous, alluring, unpredictable, and impossible to ignore.¹

Offerings at the Threshold

Samhain was the night to remember the dead, but also the time to placate the Aos Sí. Families left out bowls of milk, fresh butter, bread, or apples at the door. Sometimes offerings were poured at crossroads or near fairy mounds. These gifts were both an act of hospitality and a form of protection. To neglect them invited misfortune: milk could sour, cattle might fall ill, or travelers could be “fairy-led” into bogs and lose their way.²

Circles in the Grass: Fairy Rings

One of the most enduring signs of fairy presence were the mysterious circles found in fields — rings of mushrooms, scorched grass, or unusually lush growth. These “fairy rings” were believed to be where the Aos Sí had danced. Entering a ring on Samhain night was perilous: mortals might vanish into the Otherworld, or return days later dazed and aged beyond their years. Folklore across Ireland and Scotland warned of the danger. Protective measures included carrying iron, salt, or holy water, or offering food at the ring’s edge before stepping near.³

Good Neighbors and Ill Neighbors

Fairies were not seen as wholly good or evil. They were unpredictable, existing in that liminal space between blessing and bane. The kindly ones might reward respect with good harvests, unexpected gifts, or protection. Yet others — or perhaps the same beings in a darker mood — were known to steal cattle, sour milk, abduct wanderers, or swap changelings for human children.⁴

Samhain heightened these risks. It was the turning of the year’s light into darkness, a night when the Aos Sí were strongest. Respecting them with offerings was not optional but necessary.

Folklore at the Threshold of Samhain

Folktales abound of people who ignored the customs and paid the price. Some were struck by sudden illness after mocking the fairies. Others vanished, only to be found days later near a ring of mushrooms, unable to recall what had happened. In Irish tradition, whole hosts of fairies were said to ride through the skies at Samhain, echoing the “Wild Hunt” of other European lore. To look upon them without protection was dangerous — to join them was to be swept away.⁵

Famous Believers

Belief in fairies was not confined to farmers or villagers. The Scottish minister Robert Kirk (1644–1692) wrote of them extensively in The Secret Commonwealth, claiming fairies were real inhabitants of the unseen world. According to legend, he was taken by the fairies for revealing too much. Centuries later, folklorist Walter Evans-Wentz published The Fairy-Faith in Celtic Countries (1911), documenting testimonies from those who still claimed encounters. Even Sir Arthur Conan Doyle, the creator of Sherlock Holmes, defended the existence of fairies after the Cottingley photographs. Whether they were right or wrong, their convictions remind us how deeply fairy belief has lingered in cultural memory.⁶

Christian Overlay

The Church frequently condemned the practice of leaving food for the Aos Sí, framing it as offering to demons. Yet people persisted. Over time, some customs shifted: offerings for fairies were replaced by prayers for souls, and the feast of All Hallows absorbed older Samhain traditions. But the sense that “others” walked abroad on this night — both ancestors and fair folk — never disappeared.⁷

Modern Echoes

In rural Ireland, traces of these customs survived into the modern era. Food left out, candles lit in windows, empty seats at feasts — small gestures to remember both the dead and the unseen neighbors. In contemporary Paganism, Samhain is still a night for ancestor altars and offerings, sometimes including milk, bread, or fruit for the Aos Sí. Even now, leaving a candle in the October dark feels like participating in an ancient compact: hospitality for protection.

Closing

I’ve always believed in fairies, and perhaps that’s why these stories stir me so deeply. At Samhain, I can imagine the Aos Sí slipping between the shadows, accepting offerings left at the threshold. This blog can only scratch the surface — fairy lore deserves many more tales, from changelings to fairy queens to their role in everyday life. And we will return to them in time. But for now, we step from offerings into masks: how people disguised themselves at Samhain to survive the night of wandering spirits.
