Géde Ollgothach, son of
Ollom Fotla, was, according to medieval Irish legend and historical tradition, a
High King of Ireland. He succeeded to the throne on the death of his brother
Slánoll. His epithet means "possessing a great voice", and the
Lebor Gabála Érenn says during his reign all his subjects had voices as sweet as the strings of a
zither. He ruled for eight, or twelve, or seventeen years, before being killed by, according to the
Lebor Gabála, the otherwise unknown Fíachu son of Fíadchú; according to
Geoffrey Keating and the
Annals of the Four Masters, by his nephew and successor
Fíachu Findoilches, son of
Fínnachta. The chronology of Keating's
Foras Feasa ar Éirinn dates his reign to 880–863 BC, that of the
Annals of the Four Masters to 1241–1231 BC.
