Aine the Irish goddess of love and fertility

Aine, Goddess of Love and Fertility

The old Irish gods and goddesses, much like those of other traditional (cf. Greek, Roman, Norse), were known to be patrons of distinct favour. We have moon gods and sun gods, gods of war and gods of love. In Irish lore, Aine (or Áine) was the goddess of love and fertility.

She was the daughter of Egobail who, in turn, was the foster-son of Manannán mac Lir. She is known to have a sister, Aillen.

Áine conspired with many mortal men in the ways of the flesh. It is said that Ailill Ollamh, king of Munster, raped Áine. When his act was done, she cut off his year and killed him with her magic. It was this act that earned him the name Ollamh – meaning one-eared.

Áine’s spirit was said to dwell on Cnoc Áine (Knockainy), or Áine’s Hill in Co. Kerry. Every year, residents would climb the hill on Midsummer’s Eve (June 24) and invoke Áine of the Wisps to protect them against illness and to grant fertility to their lands and livestock. They would carry torches for her to bless and then they would wave those lit torches around their own crops and cattle to ensure health and prosperity. This practice continued long into the nineteenth century.

In the fourteenth century, a new tale arose in which Maurice, the first Earl of Desmond (located in the southwest of Ireland) raped Áine and she bore him a son, Gearóid Iarla (AD 1335-1398). When Gearóid died, it was said that he only slept, and he would be seen to ride a white horse around the banks of Lough Gur (Limerick) every seven years. Gearóid, who became the third Earl of Desmond, was a marvellous poet whose manuscripts are preserved in various works including The Poem-Book of Earl Gerald and the Book of the Dean of Lismore.

Midsummer festivities are held in Áine’s honour.

Aoife of the Land of Shadows

Aoife’s War and Peace with Cú Chulainn

The tales of old are filled with wonder. The story of Aoife, and both her rivalry with and love for Cú Chulainn, is no exception.

Aoife was the warrior-princess daughter of Árd-Greimne who resided in the Land of Shadows. Her sister, Scáthach, had been Cú Chulainn’s instructor in battle tactics. But Aoife and Scáthach were at odds with one another, and Aoife challenged her sister to war.

aoife and cu chulainn
Aoife was the sister of Scáthach.

Scáthach told Cú Chulainn to remain behind and avoid the battle, lest Aoife tries to kill him, for she was a renowned warrior of great strength. Cú Chulainn, however, followed his teacher to the Land of Shadows. Aoife seized the opportunity and challenged him to single combat, a popular tactic in ancient Irish lore.

Before their battle, Cú Chulainn came to Scáthach and asked her, ‘What does Aoife care about more than anything?’

Scáthach replied, ‘She values her horse and chariot more than all else.’

Cú Chulainn and Aoife were well-matched, for he had been trained by Aoife’s sister. But during the fight, Aoife swung and shattered Cú Chulainn’s sword. Fallen, he can only watch as Aoife raises her weapon for her final blow.

Cú Chulainn remembers the words that Scáthach had told him, and he cries out before her blow: ‘Your horse and chariot have fallen!’

Fearful, Aoife turns to seek out her chariot and its splendid horse, and Cú Chulainn knocks her from her feet.

Impressed by his cunning ingenuity, Aoife admits defeat. She is ready to die. But Cú Chulainn makes her an offer. ‘I will spare your life if you make peace with your sister Scáthach.’

Aoife accepts. She falls in love with Cú Chulainn and he with her. He lives in the Land of Shadows with her for many years, but when he is required to return to Ireland, he gives to her a gold ring. Aoife tells him that she will bear his child.

Some years later, a young warrior arrives in Ireland who is called Connlaí. Cú Chulainn challenges him to single combat and wins. And in the boy’s dying breath, Cú Chulainn is told that Connlaí is his own son, borne of Aoife of the Land of Shadows.

Oisin, son of Fionn

Who was Oisín?

Oisin (or in Irish, Oisín), sometimes known as Ossian, was a son of Fionn mac Cumhaill and Sadb (who was the daughter of the god Bodb Dearg). He was a warrior in the Fianna and is said to have been Ireland’s greatest poet.

At or around Oisín’s birth, his mother, Sadb, had been transformed into a deer. She raised the boy while in her deer form, and for years Fionn searched for them. When he found them, he named the boy Oisín, meaning fawn.

As an adult, he was one of the Fianna’s strongest champions. One day, while he was hunting with his Fianna warriors, there came the sound of horse’s hooves. When the enchanted horse came into view, it carried on its back a beautiful young woman. She was Niamh of the Golden Hair, a daughter of the god, Manannán mac Lir.

Oisín and Niamh

Oisín fell instantly in love with her, and she begged him to journey with her to Tír Tairnigiri (the Land of Promise), where her god-family resided. In an instant, Oisín mounted her horse and they disappeared across the sea.

As the years passed, Niamh bore Oisín three children – sons, Oscar and Fionn, and a daughter, Plur na mBan, which means Flower of Women.

Oisín maintained his youthful good-looks while in Tír Tairnigiri

But Oisín longed to return to his native Ireland. Seeing his grief, Niamh offered him her enchanted horse so that he could visit Ireland, but she made him promise not to dismount and touch the soil of Ireland because three hundred years had passed and if he did so, his beautiful youth would fade from him.

Oisín hurried to Ireland and sought out the Fianna for whom he missed, but he discovered they no longer existed. Christianity now presided over Ireland. Oisín was despondent.

When he accidentally fell from the magical horse, it disappeared and Oisín changed into a decrepit old man with grey hair and cataracts in his eyes.

He died soon after, though it is said that he lived long enough to meet St Patrick and be welcomed into the new church.

The Goddess Fand

The Story of Fand (goddess)

Known as the Pearl of Beauty, Fand was the wife of the sea-god Manannán mac Lir. As we’ve seen before, Manannán was considered the father of the Tuatha dé Danann.

Fand and her husband lived in the Otherworld at a place called Tír Tairnigiri (the Land of Promise), not to be confused with Tír na nÓg, the Land of Youth, where brave warriors went upon their deaths (the Otherworld locations will feature in another article; stay tuned for that).

When Fand and Manannán had an argument, he left her and ventured afar, and while he was away, Tír Tairnigiri was attacked by three kings of the Fomorii, a race of so-called evil gods who ‘came from the sea’.

Fand sent for Cú Chulainn, saying that if he protected her, he would have her love. Cú Chulainn sends Laeg, his charioteer to investigate. When Laeg returned, he told Cú Chulainn of the marvellous wonders he saw at Tír Tairnigiri. Cú Chulainn goes to the Land of Promise for himself.

Fand and Cu Chulainn
Fand and Cú Chulainn meet again.

In battle, Cú Chulainn slays the Fomorii kings and Fand takes him as a lover. He remains in her bed for a month before returning to Ireland with a view to meeting her again. When Cú Chulainn’s wife, Emer, discovers this, she sets out to kill the goddess, Fand.

As they argue about who loves him more, Emer realises that Fand does indeed love Cú Chulainn. She offers him to the goddess, thereby proving how much she loves her husband.

At this time, Manannán arrives and, seeing the spat, he demands that Fand choose between Cú Chulainn and himself. Fand says, ‘Neither of you is better or nobler than the other, but I choose you, Manannán, because you have no other wife who you are worthy of, but Cú Chulainn has Emer.’

Manannán shakes his cloak between his wife and Cú Chulainn so that they would see each other no more, and later, Cú Chulainn and Emer are given a potion of forgetfulness.

Fand never saw the warrior again.

12 of the Most Famous Irish Myths and Legends

These green hills are steeped in a rich tapestry of Irish myths and legends. In this article, we’re going to explore the most famous Irish myths and legends in our expansive history. As a storytelling nation, these fables were passed down through the generations by word of mouth, in story or song, often embellished over the years, but the core narrative remains the same.

What are the most famous Irish Myths and Legends?

Ireland has some of the most interesting tales of heroic warriors and magical artifacts from history that our Irish heritage is built upon. From Fionn mac Cumhaill to Cú Chulainn, Manannán mac Lir and more, let’s take a look at the 12 most famous Irish myths and legends.

I know it’s St. Patrick’s Day today, but bear with me. Patrick is featured elsewhere.

Fionn mac Cumhaill

Giant's Causeway
The Giant’s Causeway, said to have been created by Fionn mac Cumhaill

Fionn mac Cumhaill (Finn MacCool to those of you who don’t know) is most well known as one of the greatest warriors in Irish legend. But his mythology also reaches Scotland and the Isle of Man, too.

He was the leader of the Fianna, a largely independent band of travelling warriors, spoken most often in the tales from the Fenian Cycle. His birth name was Deimne but, according to the legends, he got the name Fionn, meaning ‘white’ or ‘fair’ when his hair turned white at a young age.

Fionn studied under the tutelage of druid-poet Finn Éces, who had spent years trying to catch the Salmon of Knowledge (more on that later). When it was eventually caught, Fionn was instructed in how to prepare and cook the fish, but he burnt his thumb and, upon sucking it, was imbued with the knowledge from the salmon.

Legend has it, Fionn mac Cumhaill built the Giant’s Causeway as a pathway to Scotland. He is often depicted as a giant, and a huge boot-shaped rock that stands at the Giant’s Causeway is said to be the fossilised remains of his shoe.

He is probably the most famous figure in Irish mythology.

Cú Chulainn

Cu Chulainn

The most famous Irish hero in our history, and probably my personal favourite, is the demigod, Cú Chulainn. Sired by the god Lugh to a mortal mother, his birth name was Sétanta (are you sensing the pattern? Perhaps to become an Irish hero, you must be given a new name! From now on, you can call me Dave).

[Aside: Setanta gets a minor mention in Book 3 of the Ailigh Wars Saga]

He got his famous alias when he killed a dog in self-defence that belonged to the smith, Culann. At Culann’s devastation, Sétanta takes the place of the guard dog at Culann’s side, thus becoming Cú Chulainn (Hound of Culann, or Culann’s Hound), until a replacement dog can be reared.

When he was 17, all the men of Ulster were cursed to suffer pains of labour, and the queen of Connacht, Medb, invades their land to steal a fertile bull. Cú Chulainn defeats her warriors singlehandedly in combat that lasted for months.

He is forced to fight against – and kill – his best friend and foster-brother, Ferdiad, when Ferdiad was bribed by Medb’s daughter. He and Cú Chulainn are often said to have been lovers. Cú Chulainn mourned Ferdiad’s death with devoted sadness.

Manannán mac Lir

Manannán mac Lir was a legendary sea-god, regarded by the Celts as the father of all fishermen, and father of Tuatha Dé Danann, after whom the entire realm of Ireland is named.

He is known as the ruler of the Otherworld, and his spectral ship, Sguaba Tuinne (meaning wave-sweeper), could navigate itself. It is often depicted as being pulled by a horse, Aonbharr, who could walk on water, and his ship would carry deceased warriors to the Otherworld.

Manannán sired many children, both gods and demigods to human mothers. It is said he appeared to a queen whose husband was at war and foretold of her king’s death if she did not sleep with him. The escapade resulted in the birth of Mongán, whom Manannán took to Tír Tairnigiri (the Land of Promise). When Mongán was returned to Ireland, he became a great warrior and king.

The Fianna

The Fiann (or collectively the Fianna) are warrior bands sometimes said to have been founded in 300 BCE, living as landless men who wandered across Ireland. They are legendary because of their versatility as fighters, explorers, chieftains, kingmakers and keepers of secrets. Although they are variously depicted as many Fiann tribes, the prominent tales describe them as a single unit.

The most famous leader of the Fianna was Fionn mac Cumhaill.

While many mythological legends are attributed to the Fianna, they are generally considered to be based on historical bands of warrior men.


Diarmuid Ua (literally ‘daughter of’) Duibhne, was said to be beautiful. In his late youth, he became a member of the Fianna.

While hunting, he and several of his Fianna brothers met an old man and a girl. Each of the men made to sleep with the girl, but she took only Diarmuid as her lover that night. She touched his forehead, giving him a mystical love spot, and no woman could look upon him without falling for his beauty.

Diarmuid was given to a foster-father, as all great heroes were, but unlike many, his foster-father was the god of love, Aonghus Óg.

When Fionn mac Cumhaill was in his old age, he was betrothed to a girl called Gráinne. But Gráinne had no wish to marry the old man. She placed a geis (a bond) upon Diarmuid to elope with her.

Lugaid Loígde

Perhaps the least known of these myths is that of Lugaid mac Daire, who was told of a prophecy that one of his sons would become the High King of Ireland. He gave each of his five sons his own name, Lugaid, so that a Lugaid would sit upon the kingseat in his name.

When the sons were out hunting one day, an old and ugly crone came to them and asked them for a kiss. She was refused by the first four sons, but when the youngest, Lugaid Loígde, agreed to kiss her, she cast off her image of an old hag and turned into the beautiful goddess, Sovranty.

She anointed him as the chosen son, and he took his place as the High King of Ireland.

There is a similar myth surround that of Niall of the Nine Hostages.

The Children of Lir

The story of the Children of Lir has its origins in Christian faith but is set in the pre-Christian era of the Tuatha dé Danann. It is the tale of the four children of Lir – Fionnghuala, Aodh, and the twins Fiachra and Conn.

Their stepmother, who felt that they took all of their father’s love and left none for her, swept the children away from him with a view to killing them. When she could not go through with the act, she took them to a lough and cast a spell upon them, turning them into white swans while they bathed.

For 900 years they were destined to live as swans. As time wore on and St. Patrick came to Ireland with Christianity, the swans were heard to sing by a holy man, Mochaomhóg. He asked that he could bind them with pure silver chains, and they were happy for him to do so, for they did not fear the holy man.

Soon, the story of the singing swans reached the ears of Deoch, wife of Lairgnen, who sought to obtain the swans for herself. When Lairgnen tried to snatch the swans, their feathers fell away to reveal the children, now grown up and ancient. The four Children of Lir were baptised in the Christian faith by the holy man before they died.

The Salmon of Knowledge

Fionn mac Cumhaill makes a return to our list in this story of the Salmon of Knowledge. The story, featuring in The Boyhood Deeds of Fionn, tells us that an unremarkable salmon ate nine hazelnuts from nine trees and ingested all the knowledge from the world.

Fionn, during his time studying under the druid-poet Finn Éces, noted that the poet had spent seven years searching for the fish. When he finally caught it, he instructed Fionn in how to cook it, and during the process, Fionn burnt his thumb on the fish’s flesh. When he sucked it to cool his thumb, he was granted the salmon’s knowledge.

From then on, whenever Fionn needed to call upon that knowledge, he could do so by sucking or biting on his thumb.


No list of the most popular Irish myths and legends would be complete without the inclusion of Nuada of the Silver Hand. He was known as the leader of the Tuatha dé Danann, the god figures of Irish lore that lived in Ireland before the advent of the Milesians (humans).

When the Tuatha dé Danann first arrived on Ireland’s shores, they were met by the Fir Bolg who lived there before them. In the first battle of Mag Tuired, Nuada lost his hand and, because he was now blemished, had to relinquish his kingship of the dé Danann.

The god Dian Cécht made Nuada a hand of silver to replace the shorn extremity, and later, Dian Cécht’s son, Miach, replaced the silver hand with one of flesh and blood.

Nuada regained his position as king and he was later slain in the second battle of Mag Tuired by Balor of the Evil Eye.

The Children of Tuireann

As far as Irish myths and legends go, few stories are as adventurous as that of the children of Tuireann. The sons of Tuireann – Brían, Iuchar and Iucharba – were born to the goddess Brigid. In a fight against their father’s enemy, Cian, Lugh’s father, the three siblings slew him and angered Lugh.

Lugh, as compensation, demanded that the sons of Tuireann fulfil eight tasks. They were to get three apples from the Garden of Hesperides; a poisoned spear from Pisear of Persia; a pig-skin from the king of Greece; a chariot and two horses from the king of Sicily; two pigs from the king of the Golder Pillars; a hound owned by king Lugh Lámhfhada of the Ioruiadh; a cooking spit from the women of Fianchuibhe from the bottom of the sea; and final they were to utter three shouts from the top of the Hill of Miodchaoin.

The Children of Tuireann succeeded in their quest, but returned to Ireland in bad shape, wounded and near death. Lugh refused to heal them.

The tale is often likened to Jason and the Argonauts.

Deirdre of the Sorrows

Deirdre of the Sorrows
Deirdre fell in love with Naoise, but their destiny was sealed.

Bring tissues. This is one of the most tragic of love stories in ancient Irish myths and legends. When Deirdre was born, her father, Felim mac Dall, was entertaining Conchobhar mac Nessa, the King of Ulster.

The king’s druid cast her fortune and said that she would be beautiful and would grow up to wed a king – however, because of her, death and ruin would come upon the land. King Conchobhar saved the baby from his warriors who sought her immediate death, and he said he would wed her when she was of age so that no other king would suffer.

But when the time came, Deirdre, now a young woman, had no interest in marriage to such an old king. When she met and fell in love with Naoise, son of Usna, they eloped together to live happily in Glen Etibhe.

But Conchobhar, incensed, feigned his acceptance of the arrangement between Naoise and Deirdre, pretending that he forgave them. In a surprise attack on route, Naoise was slain and Deirdre was forced to wed the old king. For a year, she remained at his side, never smiling, and the sorrow at the loss of her love was palpable.

Conchobhar asked Deirdre who she hated most in the world, and she replied her hatred was directed at him and the man who killed Naoise. Bound at the wrists, she was sent to Eoghan mac Duracht – Naoise’s killed – to be his wife for a year, but she jumped from the carbad (chariot), dashing her head upon a rock.

From her grave grew a tall pine tree, and from Naoise’s grave a second pine tree grew. Their branches entwined above their graves and could never be separated.

The Morrígan

Irish Myths and Legends - The Morrigan
The Morrígan would appear often as a crow or raven.

I couldn’t let this one slide. I personally love the Morrígan because her name is so similar to my surname. But aside from that, she’s an important figure in Irish myths and legends.

She was the goddess of war, death and slaughter. Is is often interchangeable with Macha, Badb and Nemain. The Morrígan was a shapeshifting goddess whose most popular form was as a crow or raven. She helped the dé Danann at the first and second battle of Mag Tuired.

In the tales of Cú Chulainn, the Morrígan made attempts to get him to sleep with her, but when he refused, they fought and Cú Chulainn wounded her. Later, when he was eventually killed, she appeared to him in the form of a crow and drank his blood.

It is the Morrígan, in part, that perpetuates the trope of crows as portents of danger or evil in modern storytelling.

Bonus Legend: King Arthur

Although the legend of King Arthur and his Knights of the Round Table is British in origin, did you know that he appears in ancient Irish myths and legends, too?

In Irish Celtic tales, he appears as the son of the king of Britain who journeys to Ireland to steal the hounds belonging to Fionn mac Cumhaill, Bran and Sceolan. Fionn and his Fianna pursue Prince Arthur to Britain to retrieve their hounds and Arthur swears loyalty to Fionn mac Cumhaill.
