Episcopal Deaths
Archived: 2 November 2026
Abstract
In 658 CE, the most securely attested Irish developments were not a single great battle or royal assembly, but a cluster of deaths that reveal how closely political authority, ecclesiastical institutions and regional society were intertwined. The annals record the deaths of Díma Dub, bishop of Condaire or Connor, and Cuiméne, bishop of Nendrum in Strangford Lough. The Annals of the Four Masters, compiled much later but drawing on older annalistic material, also place in this year the death of Sillán, bishop of Daiminis, probably Devenish in Lough Erne, on 17 May. Its same entry calls 658 the second year
