6 Most Tragic Love Stories in Irish Mythology (Part Two)

Nowadays, it’s not acceptable to commit to marriage, then have a bit of extra-marital fluff on the side. In Irish mythology, however, it was all the rage.

At the time of the Cattle Raid of Cooley, Queen Medb was on to her third husband, Ailill, who was her former bodyguard. Medb required three qualities from her men; that he be without fear, meanness, or jealousy.

She went on to have many affairs, but her lover of choice was Fergus mac Roich, for it was said it took seven men to satisfy her, or Fergus only once.

Eventually, jealous Ailill had Fergus killed, but when Medb discovered Ailill’s infidelities, she sent an assassin to kill him in revenge. So it seems that while affairs were conducted fairly openly and without shame, jealousy made such dalliances a risky business.

Often, children were born of these illicit unions. I have already told the story of Óengus’s conception and birth in Part One; he was fostered at birth by Midir of the Danann. This was not unusual; fostering children was common practice in ancient Ireland. (You can read about this in next Monday’s Myth post, The Fosterling in Irish Mythology.)

It was more normal to foster a child circa the age of seven years old. Lugh was born of a one night stand between Cian of the Danann and Ethniu of the Fomori, and fostered by Tailtiu, last Queen of the Fir Bolg; Fionn mac Cumall was fostered (at birth) by his aunt, Bodhmal, and the warrior-woman Liath Luachra; Cuchulainn was conceived on Dechtine by Lugh in a dream/ one night stand, although she was married to Súaltam mac Róich. Cuchulainn was fostered by  Fergus, Súaltam’s brother.

Lineage was important, but the bond of fosterage was considered just as strong. It seems that the conditions of a child’s conception were irrelevant; there seems no shame in being the product of an illicit once-off liaison between one’s parents.

This indicates to me that children were considered the offspring of the whole clan, rather than just two parents; and shows how relationships between men and women could have been more casual and fluid than they are today, without the moral insertions of religion.

I suspect this applied to marriage, too; the confusing number of wives and husbands the various characters in mythology had does not indicate polygamy, but rather the ebb and flow of ‘marriages’ coming to a natural end, and both partners moving on.

And so to my next favourite tragic love stories from Irish mythology…

fionn and sadbh

Sadbh was a daughter of Bodb Derg, High King of the Sidhe. When she refused the advances of the Dark Druid, he transformed her into a deer. She escaped, and after three years wandering, found her way to Almu, the home of Fionn mac Cumhall.

Here she was safe, and the Dark Druid’s spell held no power. Returned to her true form as a beautiful young woman, she and Fionn fell deeply in love. Within a year, she was expecting their first child.

Around this time, Fionn, along with his Fianna, was called away to defend Ireland’s shores against invaders. Every day, Sadbh paced the palisade, watching and waiting for her love’s safe return.

One day, she noticed a warrior and his two dogs approaching. Convinced it was Fionn and his faithful hounds, Bran and Sceolán, she ran joyfully to meet him. It was only when she was in his arms that she realised her mistake. Away from the safe haven of Almu, she was vulnerable again, and the man who wore the likeness of her husband was in fact the Dark Druid, come to claim her.

At the touch of his hazel wand, she became a little brown doe again, and together they simply vanished, never to be seen again.

Fionn was distraught to find her gone on his return. He lost all interest in everything exept searching for his lost love. After seven years, he came across a small boy, alone and wild, without the power of speech, wandering the lower slopes of Benbulben.

When he looked into the child’s eyes, he saw the look of Sadbh in them, and so he knew that this was their son. He brought him home, and named him Oisin, meaning ‘little deer’, but what became of Sadbh, he never found out.

The Persuit of Diarmuid and Gráinne

Gráinne was the daughter of Cormac mac Art, High King of Ireland. At her wedding feast to the ageing Fionn mac Cumhall, she met the young and handsome Diarmuid. They fell in love, and eloped.

They were chased across the length and breadth of Ireland by Fionn, who was jealous and angered by their betrayal. Eventually, a truce was sought by Óengus, Diarmuid’s foster-father, when Gráinne became pregnant.

The couple settle far from Fionn in his court at Almu, and live happily together, bringing four fine sons into the world. But an invitation from Fionn to join the Fianna on a boar hunt leads to Diarmuid’s death.

Fionn claims Gráinne as his bride, but she never recovers from her loss, and dies of a broken heart.

Tristan and Iseult

I first read Rosemary Sutcliffe’s beautiful version of this story when I was about nine years old, and it has stayed with me ever since. Just a chapter in the Arthurian romances, it is very much an Irish story, although it does not appear in the Irish Mythological Cycles.

Tristan travels to Ireland seeking the hand of Princess Iseult for his uncle, King Mark of Cornwall. During the return journey, they fall in love, in some versions, by drinking a love potion intended for Iseult and Mark.

When Mark learns of their betrayal, he sentences them both to death, Tristan by hanging, and Iseult by burning. Tristan escapes and rescues her, and they flee into the forest.

Eventually, they make peace with Mark, and Iseult agrees to return to her husband, but Tristan is banished. On his travels, he meets and settles with another Iseult, known by the epithet ‘of the White Hands’, who is the daughter of Hoel of Brittany.

In later years, Tristan is wounded by a poisoned lance. He sends for Iseult of Cornwall, for only she is skilled enough in the healing arts to repair such a wound. He is uncertain that she will come; he asks that if she does, the ships sails are to be white, but if she refuses, they must raise a black sail.

Of course Iseult rushes to be with her lover again. The ship’s captain follows Tristan’s orders, and a white sail is hoisted. Too weak to leave his bed, Tristan asks his wife, Iseult of the White Hands, about the colour of the sail. In a sudden fit of jealousy, she answers “Black.”

Tristan dies from grief, and when Iseult of Cornwall discovers his dead body, she too dies from a broken heart. After they are buried, a hazel tree grows from Tristan’s grave, and a honeysuckle from Iseult’s, and it was said that the honeysuckle clung to the hazel so tightly, they could never be pulled apart.

I hope you have enjoyed these sad but beautiful stories. In reality, they are far more intricate and glorious than I can show in just a few lines. If you missed Part One, you can read it here.

    • Oooh that’s a tough question! On the one hand it would be fascinating to see what secrets lie beneath it. On the other hand, it kind of feels like desecration. I’m not sure. I kind of want to know. We could learn a lot. But sometimes its best to let things lie. What’s your view, Colin?


      • In my younger days, if it was up to me rocks would have been flying in all directions in the excitement of seeing what was buried below and I’d probably miss all the important archaeological finds, Something like that happened on the Hill of Tara when a group of people were looking for the Arc of the Covenant 100 years ago – desecration really. When I visited Tara they were having to redo the Mound of Hostages because when it was excavated just 50 years ago i was told it wasn’t done very well. Archaeologists often complain about the bad work of predecessors and I think that’s why sometimes they don’t race into things like finding out what’s beneath the cairn at Knocknarea. It’s amazing the things you keep telling us in your blogs and perhaps the mound is something that should never be touched and storytellers can keep writing stories for another 10,000 years, or however long it’s been since it was built. Have you given any thought to when you will take a peek inside the Cave of the Cats where Medb’s name is on the lintel. You often have to make a sacrifice when visiting a sacred site and one of the sacrifices is that you may get a muddy bottom.


  1. What beautiful yet sad stories, Ali. The last one really touched my heart. It’s lovely to think that they are hugging each other and will never let go. It reminds me so much of disaster movies when the end is coming and a loving couple holds each other tight.

    • They are, aren’t they, Hugh? The ending of the last one is particularly beautiful. There is another tragic love story about Baile and Aillin which also has trees growing out of the dead lovers graves and twining together, but Jane Dougherty wrote that one for our Grá mo Chroí book, so I didnt feature it here. But if you want to read it, you can download a free copy of the book on Smashwords!

  2. You’d think Fionn’s two foster mothers would’ve done a better job of teaching him about healthy relationships with women. Pity he wasn’t raised by Maebh eh?!

    • Yes, they were a bit on the vengeful side, weren’t they? I guess its a bit safer to have an affair these days, if one is so inclined, although I’m not so sure that is a good thing.

  4. The Irish myths are full of twists and turns and it seems the love stories are no different.Constancy and faithfulness aren’t the hallmark of marriage in the ancient tales but it does seem to have been the case in the love stories that the couples were faithful unto death, with death coming to one,other or both far too soon.

    • Yes exactly, David. You hit the nail on the head. So perhaps love was an honourable thing but marriage was merely a practical necessity for furthering a clans success and the begetting of children.
