High, large remains of a circular cyclopean tower, called Dun-Aengus, ascribed to the Fir-bolg or Belgae; or, individually, to the first of three brothers, Aengus, Conchobar and Nil, who reached Aran Islands from Scotland in the 1st century A.D.
CUCHULINN (Cuchulinn; pronounced "Coohoollin"), the chief warrior in the Conchobar-Cuchulinn or older heroic (Ulster) cycle of Ireland.
The god Lug is represented as having been swallowed in a draught of wine by his mother Dechtire, sister of Conchobar, who was king of Ulster.
But it is not unlikely that this story was invented to supersede the account of the incestuous union of Conchobar with his sister, which seems to be hinted at on various occasions.
Cathbu (Cathbad), the Druid connected with Conchobar, king of Ulster, in the older cycle is accompanied by a number of youths (Ioo according to the oldest version) who are desirous of learning his art, though what this consisted in we are not told.
We are further told that at the court of Conchobar no one had the right to speak before the Druids had spoken.
The Celtic heroic saga in the British islands may be divided into the two principal groups of Gaelic (Irish) and Brython (Welsh), the first, excluding the purely mythological, into the Ultonian (connected with Ulster) and the Ossianic. The Ultonianis grouped round the names of King Conchobar and the heroCuchulainn, " the Irish Achilles," the defender of Ulster against all Ireland, regarded by some as a solar hero.
