Annals Of Tigernach
The "Annals of Tigernach" (Teerna), written in Irish with an admixture of Latin, deal chiefly with the history of Ireland. Tigernach was Abbot of Clonmacnoise and Roscommon and died in 1088;
it is conjectured by M. d'Arbois de Jubainville that his annals (valuable but meagre) were based on some ancient records kept uninterruptedly at Clonmacnoise from 544, the year of its foundation.
These annals were edited by Whitley Stokes in the sixteenth and seventeenth volumes of the "Revue Celtique" (Paris, 1895-96).
