A number of Irish annals, of which the earliest was the Chronicle of Ireland, were compiled up to and shortly after the end of the 17th century. Annals were originally a means by which monks determined the yearly chronology of feast days. Over time, the obituaries of priests, abbots and bishops were added, along with that of notable political events. Non-Irish models include Bede's Chronica maiora, Marcellinus Comes's Chronicle of Marcellinus and the Liber pontificalis. Chronology The origins of annalistic compilation can be traced to the occasional recording of notes and events in blank spaces between the latercus, i.e. the 84-year Easter table adopted from Gaulish writer Sulpicius Severus (d. c. 423).

(See External Links below) The famous epic political tract Cogad Gáedel re Gallaib also contains a great deal of annalistic material from the Viking Age in Ireland which is to be found in no other surviving sources.
