Tucked away in the beautiful scenic landscape of County Roscommon, Ireland, lies a mysterious and legendary cave known as “Oweynagat” (pronounced “Oen-na-gat”), also known as ‘Cave of the Cats’. This ancient cave is believed to be the mythical entrance to the Otherworld, Ireland’s Gate to Hell, a supernatural realm in Irish mythology. Oweynagat is one of the most important places linked to the ancient Celtic festival of “Samhain”, the forerunner to the modern Halloween. Steeped in lore and shrouded in mystery, Oweynagat is a powerful symbol of Ireland’s ancient spiritual heritage and the very origins of Halloween.

The Mythology of Oweynagat

Oweynagat is part of Rathcroghan, a major archaeological complex that served as a royal site for the ancient Irish kingdom of Connacht. This area comprises over 250 archaeological features; it is an area surrounded by many ancient sites, monuments, holy wells and standing stones. Rathcroghan is deeply linked to Queen Medb, a famous warrior queen in Irish mythology, and features heavily in stories of the “Ulster Cycle”, one of the four great story cycles of Irish mythology.

Oweynagat is often described in these tales as the “gateway to the Otherworld.” Irish mythology describes the cave as a place where powerful forces of the supernatural were said to reside. During Samhain, it was believed that the veil between the human world and the Otherworld was at its thinnest, allowing spirits, fairies, and other entities to pass through more easily. The cave itself was seen as a physical gateway through which supernatural beings could enter the mortal realm, making it a focal point for rituals and lore featuring Samhain.

One of the most famous legends associated with Oweynagat in relation to Samhain is known as ‘The Adventures of Nera”. One Samhain night, Ailill and Medb, ancient rulers of Rathcroghan, dared anyone to tie a rope around the foot of a captive hanging on a nearby gallows. They promised a reward to anyone who succeeded. Nera, a brave warrior, accepted this challenge. Decked out in his armour, he approached the captive and managed to tie the rope, only for the captive to come to life, asking Nera for a drink as a last request.

Nera agreed and carried the captive on his back to find water. As they passed three houses, each were marked by strange omens such as a lake of fire surrounding one, the captive finally drank from a slop bucket in one of the homes. In a final act of revenge, he spat his last sip on the faces of the house’s occupants, who died instantly. Returning the captive to his execution site, Nera then witnessed a horrifying vision of his home in flames and his people slain by an otherworldly army. When he followed this mysterious army into the underworld of Oweynagat, he found himself before a faery king.

The faery king ordered Nera to bring wood daily to a house within the faery mound, where Nera met and married a faery woman. She shared many of the secrets of the faery world, warning him that his vision of his people’s demise could come true if he didn’t alert them. When Nera finally returned, only moments had passed in the human world despite his long stay in the faery mound.

Ailill and Medb, taking Nera’s warning seriously, prepared to attack the faery mound the next Samhain. Nera returned to his faery wife, who revealed she was pregnant with his child and encouraged him to escape with his family from the faery realm before the attack. He agreed and watched as the men of Connacht destroyed the faery mound, retrieving the powerful Crown of Briun, one of Ireland’s three great treasures.

Nera, however, remained forever tied to the faery world, never to be seen again in the mortal realm. The tale ends with his fate sealed, waiting in the faery mound until the end of time. The cave has since been claimed to be the birthplace of Halloween due to this story being set at Samhain.

Another legend relating to the cave at Oweynagat is that it is the home of the Morrígan, a Celtic war goddess who, according to tradition, emerges from the cave each Samhain to bring chaos to the land.  Ailill and Medb’s cats, who were supposed to roam out of Oweynagat on Samhain, are among the other mythological animals connected to the cave. They represent the chaos and the forces of nature that were thought to be let loose on this night.

Samhain: The Roots of Halloween

Samhain celebrations have a long history that predates written records. Samhain heralded the start of the dark of winter and the conclusion of the harvest season for the Celts. It was thought to be observed between October 31st and November 1st, sunset to sunset. Due to it being a transitional period, there was thought to be little separation between this world and the Otherworld. The veil thinned, enabling communication between living people and supernatural entities.

According to legend, Oweynagat cave is thought to become a portal to the otherworld at this time of year, where faeries and mortals may enter each other’s respective worlds. According to folklorist and professor, Dorothy Bray, “Samhain was a time charged with great supernatural energy and ordinary natural laws were suspended. The idea of the otherworld developed into the idea of the afterlife, so Samhain became a time when the worlds of life and death meet, when the souls of the dead return and can be seen.”

According to local archaeologist and historian, Daniel
Curley, “Monsters and manifestations would emerge, led by the goddess Morríghan,
to create a world ready for winter, including birds with foul breath that would
strip leaves from trees. Locals would stay indoors in fear of being dragged
into the other world when the ghouls had finished ravaging the land. If you had
to go outside you wore a costume and mask to look hideous. That way you would
be left alone and not dragged into the otherworld.”

Feasting, bonfires, and rituals honouring the ancestors were all part of Samhain. People made food and drink offerings outside their homes to calm any wandering spirits who were thought to be free to roam on this night. People sometimes wore frightening masks or costumes to either ward off or blend in with any supernatural creatures that had passed over into our world, and bonfires were lit to guide the way to lost spirits.

From Samhain to Halloween

Many ancient traditions were adapted and reinterpreted to conform to Christianity as it expanded over Ireland. On November 1st, the Church created All Saints’ Day, which is a day to commemorate saints and martyrs. The night before was called All Hallows’ Eve, which later transformed to “Halloween.”

Samhain rituals gave rise to modern Halloween traditions including trick-or-treating, pumpkin carving, and the wearing of spooky costumes. Wearing costumes to ward off any lost spirits gave rise to the Halloween custom of dressing up as monsters, ghosts, or other terrifying creatures. The modern custom of “trick-or-treating,” in which youngsters knock on doors looking for sweet treats, evolved from the habit of leaving out food offerings.

The jack-o’-lantern, another popular Halloween custom, has Irish origins too. In order to ward off evil spirits, people in Ireland used to carve swedes and place candles inside to make glowing lanterns. This custom was carried to America by Irish immigrants in the 19th century, and it eventually developed into the pumpkin lanterns we are accustomed to today

Oweynagat Cave Today

A trip to Oweynagat Cave provides a window into the past for those who are interested in learning more about the Irish origins of Halloween. Although the cave appears to be damp, murky and unassuming, it is simple to see why ancient humans sensed a power in its presence. Visitors may feel the weight of centuries’ worth of history, rituals and legend hanging in the air when they first enter Oweynagat cave.

Today, Halloween is mainly about entertaining costumes, sweets and light-hearted frights. However, Halloween’s origins lie much deeper; it has to do with ancestors, the cycles of nature, and myths surrounding the invisible realm. Oweynagat Cave is a mysterious reminder of the mythical beginnings of this well-known festival, as well as Ireland’s contributions to a festival now observed world over.

It is easy to imagine the ghosts of Rathcroghan’s ancient lands and possibly the cave’s mythical cats emerging from the depths of Oweynagat cave as Samhain draws near, serving as a powerful reminder that the real spirit of Halloween continues to reverberate throughout Ireland’s ancient landscapes.

The Legend of Stingy Jack: The Haunting Legend Behind the Halloween Jack-o’-Lantern

Halloween, a time of ghosts, ghouls, and goblins, is a time when the veil between this world and the next is at its weakest and spirits roam the earth.  One legend looms large in the heart of Halloween itself – the macabre tale of Stingy Jack. This eerie figure from Irish folklore was the origin of the popular Halloween tradition of carving jack-o’-lanterns. Join me as I explore the dark legend of Stingy Jack and his connection to Halloween.

Who was Stingy Jack?

The legend of Stingy Jack originated from the depths of Irish folklore. Stingy Jack was a notorious trickster known for his deceit and cunning. Jack’s reputation for manipulation and shrewdness was so notorious that he even caught the eye of the devil himself.

The Legend and Faustian Bargain

The legend has it that Jack was out one night after having a tipple in his local tavern when he stumbled upon Satan on a country road. The devil demanded his soul, but Jack pleaded to have a last drink of ale with him in the local pub.  After their drinking session, Jack used his cunning to trick the devil into transforming himself into a coin to pay for their drinks. Jack placed the devilish coin in his pocket where he kept a crucifix, thereby stopping the devil from returning to his true form.

Jack was very pleased with himself and his wheeze, but eventually freed Satan. However, not one for missing a trick, Jack only agreed to free the devil after he had struck a Faustian bargain. Jack made a deal that the devil should spare his soul for ten years.

Ten years passed and Jack encountered Satan once again while he was stumbling home from the pub. Using his cunning once again, he asked to have a last snack of an apple from a nearby tree. The devil foolishly climbed the apple tree to fetch him an apple. Once up the tree, Jack surrounded its trunk with crucifixes, trapping the devil in its branches. Realising he’d been had, the devil pleaded to be let down, but not before agreeing never to take Jack’s soul. However, this bargain came with a haunting clause, one that would forever alter Jack’s fate.

Jack’s Just Desserts

Eventually, Jack’s drink-fuelled life came to an end and he died. His soul prepared to ascend to Heaven, however as he tried to enter the pearly gates he was stopped by St Peter. Jack, demanding to know why he could not enter Heaven, was taken to see God, who told him that due to his sinful lifestyle, trickery, and deceitful ways, he was not eligible for Heaven.

Jack then descended to the Gates of Hell and begged Satan for admission into the underworld. However, the devil, fulfilling his obligation to Jack, could not take his soul.  Jack was instead condemned to roam the earth in perpetual darkness. The devil, however, felt sorry for Jack and gave him an ember to light his way, which he placed inside a carved turnip to create a makeshift lantern. This eerie lantern forever guides his eternal search for a final resting place as he wanders the world between the planes of good and evil.

The Birth of the Jack-o’-Lantern and Stingy Jack’s Influence on Halloween

Over time Stingy Jack’s turnip lantern became synonymous with Celtic Samhain and Halloween. Irish immigrants brought their traditions to America and soon discovered that the local pumpkins, larger and easier to carve, made ideal lanterns. This transformation from turnips to pumpkins gave birth to the iconic ‘Jack-O’-Lantern’ we know today.

As you prepare for Halloween and carve your pumpkin jack-o’-lanterns, remember the eerie folkloric origin of this beloved tradition.  Stingy Jack, with his cunning trickery and Faustian bargain, has left an enduring spark of folklore as his cursed spirit lights our way through the mysterious and magical night of Halloween. So, when you see those flickering jack-o’-lanterns, spare a thought for Stingy Jack forever condemned to wander the earth with only a lantern to light his way.
