Patrick blessed him
Martyrological notice
Diarmaid, Bishop, of Inis-Clothrann, in Loch-Ribh. He is of the race of Fiachra, son of Eochaidh Muighmheadhoin. Dedi, daughter of Trena, son of Dubhthach h-XJa Lughair, was his mother, and this Dubhthach was chief poet to Laoghaire, son of Niall, who was monarch of Ireland, at the coming of Patrick into Ireland, and he showed honour and great veneration to Patrick, and believed in him, as appears from Patrick’s Life, and Patrick blessed him. It was Diarmaid that composed the Cealtair DichiU' in verse, in which he invoked a countless number of the apostles and saints of the world, and of the saints of Ireland, as a protection and shelter for himself, just as Colum composed the hard poem called the Luirech or Sgiathluirech of Colum-Cille, which begins: “The shield of God as a protection upon me,” &a “They shall protect me against every danger,” was the beginning of what Diarmaid composed.
