He, like his predecessors, dwelt at the three ringed Bathleann, 1 a very early 

 earthwork, in whose inner rampart sepulchral urns were found. It lies at 

 Garranes in Kinelmeaky, six miles north from Bandon. About this time, 

 probably, the " Book of Bights " was recast, or compiled. It gives the tribal 

 privileges — 



' ' Entitled is the King of great Ui Eathach 

 To a coat of mail and a spear for combat, 

 And to two rings of gold, 

 And to two steeds of no bad temper." 2 



It is said that in presence of the chief of the Dalgcais the chief of Ui Eacach 

 only bowed his head, performing no other act of homage. 3 The tribe were 

 evidently expert ship-men, as Brian " commandeered " them along with the 

 Danes of Dublin and Waterford for a naval expedition. 4 



Cian with Tadhg, Brian's son, removed the wounded to Kilmainham after 

 the battle of Cloiitarf. His claim of supremacy over the Dalgcais at Mullagh- 

 mast was ill-timed, but those, like our times, were uprooted from the older 

 balance ; and in his time, it is believed, the quarrels began that split the 

 Ui Eacach into Cinel Aedha (Kinelea) and Cinel Laeghere, who " never met 

 in amity " again. 5 Cian was glad of the aid of Donchadh Brian's son perhaps 

 a year later; and soon after he and his brothers fell. Mathgamhain, his son 

 by Sadbh, ruled over the Cinel Aedha, the Cinel Laeghere having migrated 

 to Magunihy in 1015. He died in 1028 (Leabhar Oirus), or ten years 

 later (Four Masters) ; Sadbh died in 1031. From him is derived the name Ui 

 Mathgamhna or Mahony. 



Before resuming the fragmentary Annals of their chiefs (for we are more 

 concerned with origins and early history, save when later records attach to 

 the remains we specially study), let us define their territory. As the older 

 Dalgcais territory is represented by the Bishopric of Killaloe, the Ui 

 Fidhgeiute by Iniscatha, and Limerick, and the Ui H Eidersceoil by Boss, so 

 the see of Cork closely represents the Ui Eacach tribe-lands at the time of 

 the Synod of Bathbreasail, about a.d. 1112. It defined the limits of Cork 

 diocese as from Corcagh to Cam ui Xeid, from the Blackwater to the sea. 6
