CORNISH DEDICATIONS. 139 



From Domnacli Fiacc he moved to Sletty, near Carlow, for 

 what reason we do not know, and made that his principal estab- 

 lishment. He had some able and experienced men with him, men 

 who made their mark in the Church. One was Ninnidh who has 

 been identified with Maucen or Mawgan. In Tirechan's Collections 

 towards the Life of S. Patrick, he is called Manchan. At the 

 wish, or by the advice of the apostle, this man crossed over to S. 

 David's Head, in Wales, and there established the great nursery 

 of saints, Ty Gwyn. The district ruled by Crimthan was too 

 unsettled, and the prospects of disturbance too threatening for 

 Fiacc and Patrick not to desire to have the Missionary School 

 removed fi'om Leinster. Another, who was with Fiacc was Paul, 

 who succeeded Ninnidh as head of Ty Grwyn, the same Paul the 

 Old, whose inscribed monument is preserved at Dolau Cothi. 

 Paul had been a disciple of S. Grermanus of Auxerre. 



Other helpers were men of experience, but who have left less 

 mark. Cattoc or Cattan, Patrick's priest ; Augustine, who had 

 come to Ireland with Palladius, and who, on the failure of that 

 mission, had accompanied his patron to North Britain. After the 

 death of Palladius, Augustine offered his services to Patrick, who 

 placed him with Fiacc. 



Others of less note were Tagan or Teece, an Ossoryman ; 

 Diarmid a kinsman of Fiacc, and Fedlemid. 



Fiacc had been baptised in 460, and was consecrated very 

 shortly after and sent on his mission in Leinster. 



In 465 a revolution occurred. The half brother of Fiacc, 

 called Oengus, succeeded in enlisting allies and in stirring up the 

 clansmen between the Nore and the Barrow. A battle was fought 

 and Oengus killed his grandfather, Crimthan, with his own hand. 

 He then obtained for himself his patrimony. Whether his 

 brothers were restored is not known. But the Hy Cennselach 

 were not disposed to bear their defeat, and retaliated, so that for 

 some years the whole of Leinster was in commotion. 



In 480 Finnchad, king of the Hy Cennselach was killed by 

 Cairbre, son of Niall, in a battle at Graine, north of Kjildare, in 

 which the Leinster men were fighting among themselves. In 

 489 a desperate conflict took place at Kelliston in Carlow, in which
