already stated, runs down the steep hill on which this ruin
is based, and discharges itself into the bay of Tralee, a short
distance to the north, corresponding exactly with the de-
scription given by history of the fort of Dun Deaghaidh.
Mac Luigheach, a famous champion of this sept, command-
ed the Clanna Deaghaidh at the battle of Gabbra, and was
slain in that engagement, according to the annals of Innis-
fallen.
The militia, or knights of Thomond or North Munster,
were the Clanna Baoiscne,' so called from Baoiscne, their
principal ancestor, who, according to the Book of Ballimote,
now deposited in the library of the Royal Irish Academy,
was the second son of Nuada Necht of the royal race
of Leinster, and fifth direct ancestor of Fionn the son of
Cumhall, the son of Treanmor, the son of Salt, the son of
Elton, the son of Baoiscne.
Fionn soon afterwards received the investiture of For-
maoil na bh-Fian, a district in Hy-Kinsellagh,^ concerning
which there has been much conjecture, by the donation of
his cousin and relative Fiachadh Baiceadha,^ then king of
Leinster and youngest son of Cathaoir Mor. The Clanna
Baoiscne were also called Fianna Finn, whilst Fionn Ua
Baoiscne was their leader and before he took the general
command. Oisin the son of Fionn was their chief at the
battle of Gabhra, in which his son Oscur fell in an ambnsli,
laid for him by Cairbre Lifleachair, monarch of Ireland,
A.D. 277.
It is probable that, inasmuch as Ireland was in these early
days much exposed to the descents of African and Northern
pirates, a strong necessity existed for the formation of these
• Clanna Baoiscne. For further particulars of this tribe and their
