In Irish mythology, Egobail was a foster son of Manannan mac Lir and father of Aine. The mythology of pre-Christian Ireland did not entirely survive the conversion to Christianity, but much of it was preserved, shorn of its religious meanings, in medieval Irish literature, which represents the most extensive and best preserved of all the branches of Celtic mythology. ... In Irish mythology, Manannan mac Lir was a sea and weather god. ... In Irish mythology, Ãine (also Aillen) was a goddess of love, growth, cattle and the moon. ...
In Goidelic mythology, Áine (also Aillen) was a goddess of love, growth, cattle and the moon.
She was the daughter of Egobail, and sister of Aillen and/or Fennen.
In some versions of the myth, she is the wife of Gerold Iarla; in others, rather than being married, he raped her, and may have been subsequently killed by her; in yet other versions of her myth, she is the wife of Manannan mac Lir.
