Aed (god)
Aed, or Aodh, is the prince of the Daoine Sidhe and a god of Irish mythology. He is known from inscriptions as the eldest son of Lir, High King of the Tuatha de Dannan, and Aoibh, a daughter of Bodb Dearg. Aed is elsewhere described in the Dindsenchas as being the Dagda's son and brother of Cermait and Aengus killed by Corchenn of Cruach for seducing Corchenn's wife.
Etymology
Aed's name is derived from the Old Irish word for fire, derived from a Proto-Indo European verb meaning "to burn" or "to kindle". In the Dindsenchas, he is given the epithet "of the wind-swift horses" and called "Aed Luirgnech," meaning "big-shins".Children of Lir
According to tradition, Aoibh died in childbirth after bearing Lir four children : Fionnuala and Aodh were the first pair and Fiachra and Conn were the second. Aoife, the second wife of Lir, and in some versions of the story, the sister of Aobh, was very jealous of the children and conspired to kill them on a journey to see Bodb Dearg, the King of the Tuatha de Dannan. But for love of the Children of Lir, the servants of Aoife would not slay the children, and so she cursed them to live as swans for 900 years: 300 upon Lough Derravaragh, 300 in the English Channel, and 300 on the Sea of Moyle.Legend says they kept their voices and learned all the songs and tales of Ireland, as well as the many languages brought by travelers from distant places.
There are numerous variations on the culmination of the story after the breaking of Aoife's curse, and most are obviously influenced by stories from Christianity. For more on the story, see the article on the Children of Lir.
