The 'Annals of Tigernach' are the remnants of a chronicle (written in a mixture of Latin and Irish), traditionally associated with Tigernach hua Braein, Abbot of Clonmacnois, who died in 1088. However, as Marjorie O. Anderson notes, in 'Kings and Kingship in Early Scotland': She concedes that, though the title "is a misnomer", it is "now too well established to be discarded".   Although the beginning of each new annal is indicated, the chronicle rarely provides A.D. references. In the section covering the years 489-766 (which exists in a 14th century manuscript), up to the annal corresponding to 651, a ferial number is added to indicate the day of the week that the Kalends (i.e. the 1st) of January fell in that year.
