The Life of St. Declan of Ardmore

Declán of Ardmore was an early Irish saint of the Déisi Muman, who was remembered for having converted the Déisi in the late 5th century and for having founded the monastery of Ardmore (Ard Mór) in what is now Co. Waterford. The principal source for his life and cult is a Latin Life of the 12th century. Like Ailbe of Emly, Ciarán of Saigir and Abbán of Moyarney, Declán is presented as a Munster saint who preceded Saint Patrick in bringing Christianity to Ireland. He was regarded as a patron saint of the Déisi of East Munster.

The most blessed Bishop Declan of the most noble race of the kings of Ireland, i.e., the holy bishop who is called Declan was of the most noble royal family of Ireland—a family which held the sceptre and exacted tribute from all Ireland at Tara for ages. Declan was by birth of noble blood as will appear from his origin and genealogy, for it was from Eochaidh Feidhleach, the powerful Ardrigh of Ireland for twelve years, that he sprang. Eochaidh aforesaid, had three sons, scil.:—Breas, Nar, and Lothola, who are called the three Finneavna; there reigned one hundred and seven kings of their race and kindred before and after them, i.e. of the race of Eremon, king of Ireland,—before the introduction of Christianity and since.
