Cairbre |
In the beginning of the 4th century, three warlike princes, called the Three Collas, sons of Eochy Doimhlein, son of Cairbre Lifeachar, legendary High King of Ireland, of the race of Eremon, made a conquest of a great part of Ulster, which they wrested from the old possessors, princes of the race of Ir, called the Clanna Rory, or Rudericians.
Cath Gabhra exists in many versions, and is referenced often in other works, including poems about Cairbre Lifechair in the Book of Leinster and in the long narrative Acallam na Senórach.
