Cnoc Báine and Heaven-Fire
Archived: 30 October 2026
Abstract
In 772, despite chronological uncertainties in the annals, Donnchad Midi of Clann Cholmáin led a hosting to Cnoc Báine in Airgialla, projecting Midland power northwards amid changing Uí Néill leadership. Connacht lost Áed Aithgén of Uí Maine and Art of Aidne, while the law of saints Comán and Aedán was renewed across its three divisions. On St Michael’s Day, lightning, thunder and heaven-sent fire terrified an assembly, prompting widely observed penitential fasts. Airlid of Clonard, Máel Aichthen of Cluain Eidnig and Suibne of Iona died, illustrating ecclesiastical networks linking Ireland, regional politics and the wider Columban world beyond its shores.
