Career
Eochaid was the author of more than twenty surviving quasi-historical, genealogical and topographical poems, many of which were incorporated into Lebor Gabala Erenn. At the time of his death he was superior of Clonfeacle and Lios Aoigheadh (unidentified). The Annals of Ulster contain Eochaid"s obit sub anno 1004, stating:
"Eochaid ua Flannacáin, superior of Les Oeiged and of Cluain Fiachna, a master of poetry and historical lore, died in the 69th year of his age."
The obit was accompanied by a stanza commemorating him:
"The full form of beautiful Eochaid/An ascending poetic psalm of happy aspect/eochaiss that he does not approach from behind(?)/A key to the lock of Ireland"s ignorance./‘Eochaid of the undying knowledge’/Has long been an incontrovertible name for him;/Foreign reproach in the matter of learning or wisdom/He has no cause to answer./".
