Fiacha mac Delbaíth

In Irish mythology, Fiacha (Irish pronunciation: [ˈfʲiːəxə], sometimes Fiachu, Fiachra or Fiachna), son of Delbáeth, of the Tuatha Dé Danann, was a legendary High King of Ireland. According to the Lebor Gabála Érenn, he took the throne after his father was overthrown by Caicher son of Nama, brother of Nechtan.[1] The Annals of the Four Masters and Geoffrey Keating say he overthrew his father himself.[2] His mother was Ernmas. He had three daughters, Banba, Fódla, and Ériu, by his own mother.[3] He reigned for ten years, before he and his nephew Aoi Mac Ollamain were killed in battle against Éogan of Imber.[1]
