« Out with you upon the wild waves, Children of the King! Henceforth your cries shall be with the flocks of birds. »

The Children of Lir is an Irish legend. The original Irish title is Clann Lir or Leanaí Lir, but Lir is the genitive case of Lear. Lir is more often used as the name of the character in English. The legend is part of the Irish Mythological Cycle, which consists of numerous prose tales and poems found in medieval manuscripts.

Bodb Derg was elected king of the Tuatha Dé Danann, much to the annoyance of Lir. To appease Lir, Bodb gave one of his daughters, Aoibh, to him in marriage. Aoibh bore Lir four children: one girl, Fionnuala, and three sons, Aodh, Fiachra and Conn. Aoibh died, and her children missed her terribly. Wanting to keep Lir happy, Bodb sent another of his daughters, Aoife, to marry Lir. Jealous of the children's love for each other and for their father, Aoife plotted to get rid of the children. On a journey with the children to Bodb's house, she ordered her servant to kill them, but the servant refused. In anger, she tried to kill them herself, but did not have the courage.

Instead, she used her magic to turn the children into swans. When Bodb heard of this, he transformed Aoife into an air demon for eternity. As swans, the children had to spend 300 years on Lough Derravaragh (a lake near their father's castle), 300 years in the Sea of Moyle, and 300 years on the waters of Irrus Domnann Erris near to Inishglora Island. To end the spell, they would have to be blessed by a monk. While the children were swans, Saint Patrick converted Ireland to Christianity.
