[Ir., circlet (?), bracelet (?)].
Faithless retainer of Deirdre and Noíse in Longas Mac nUislenn [The Exile of the Sons of Uisnech]. Buinne, sometimes called Ruadh [the Red, or Rough Red], was a son of Fergus mac Róich. Initially a brave defender of Deirdre and Noíse, Buinne accepts a bribe from Conchobar and abandons the lovers. The bribe is all the land on the side of a mountain, which becomes a desert when Buinne tries to occupy it.
