Clonmacnoise’s Stone Church

Archived: 27 October 2026

Abstract

In 909, Flann Sinna, king of Tara, and Colmán Conaillech sponsored a stone church and sacristy at Clonmacnoise, whose surviving north wall attests early Irish monumental masonry. Situated beside the Shannon, the foundation served a populous religious and lay settlement while displaying royal power, ecclesiastical wealth and political connections. The nearby Cross of the Scriptures similarly linked Christian teaching with patronal commemoration. Following Flann’s victory at Belach Mugna in 908, his ally and son-in-law Cerball of Leinster died, prompting dynastic change. Annals also note regional rulers’ and churchmen’s deaths, cattle disease, and killings in Brega. Some battles remain insecurely dated.

Cormac’s Eighty Ferryings

Archived: 28 October 2026

Abstract

In 907, Cormac mac Cuilennáin, king-bishop of Cashel, and Flaithbertach mac Inmainén led Munster forces through the midlands, challenging Flann Sinna and Uí Néill influence. Annals record fighting at Mag Léna, the death of Máel Craíbe of Cenél Fiachrach, Connacht hostages, and fleet-borne plundering around Lough Ree. Their Christmas campaign reached Uí Néill territories, Mag Aí and Clonmacnoise, requiring eighty ferryings, an uncertain phrase indicating arduous transport. These expeditions demonstrated Munster’s mobile, alliance-based power without creating unified rule. Cét became king of Corcu Modruad locally. Mortality is noted cautiously in Ulster’s annals; Cormac’s defeat came the following year in 908.
