In post 18th-century scholarship, the tale has often been grouped with the Oidheadh chloinne Uisnigh ("The Fate of the Children of Uisnigh") and Oidheadh chloinne Tuireann ("The Fate of the Children of Tuireann") as the Trí truagha na sgéalaigheachta, i.e. "The three sorrows of storytelling", also known as "The Three Sorrowful Tales of Erin".
[2][3] Scholar and folklorist Robin Flower has suggested that all three tales may have had a common author sometime in the 14th century, by someone in the circle of the Mac Fhirbhisighs in north-west Connacht.
[2] The legendary historical setting of the story is the end of the dominion of the Tuatha Dé Danann in Ireland, and the corresponding rise of the Milesians.
One day, she set out in her chariot with the four children, with design to kill them, and called her entourage to slay them, stating that because of them she had lost Lir's love, and promising them rich rewards.
Next she took them to Loch Dairbhreach and made them bathe, but once in the water, she cast a spell of metamorphosis in order to transform them into four white swans.
[n 3] She also foretold that by expiration of the period of the spell, Lairgenn (the great-grandson of the King of Connacht), and Deoch (the great-granddaughter of the King of Munster) would be wed. Aoife relented a little and allowed the children to retain the power of speech, stating they would sing plaintive songs without equal, and that they would not be distressed by being in the forms of birds.
They told him of Aoife's evil act, and Lir and his people lamented, though that night they stayed and listened to the swans' song.
At the Maoilé a cruel storm separated them, and though they eventually reunited their time there was wretched, with extremes of cold and weather to contend with, but they could not leave, as it was their lot to stay in the waters there.
[46-52] Eventually the swans came across a company of the De Danann and of the Milesians who had been seeking them, led by Aodh and Fergus sons of Bodb—near the mouth of the Banna.
Eventually the time allotted to Iorrus Domhnann passed and they decided to go to Sioth Fionnachaidh, where Lir lived.
Eventually Saint Patrick and Christianity came to Ireland, and one day the holy man Mochaomhóg arrived at Inis Gluairé—the swans heard him ringing a bell calling matins, and became frightened at the sound.
