Annals
In the Middle Ages in the Western Church there were written tables to show that date of Easter for a certain number of years or even centuries. These Paschal tables were thin books in which each annual date was separated from the next by a more or less considerable blank space. In these spaces some monks wrote down the important events of the year. The writing of these Annals was begun at the end of the 7th century and among the Irish – see the Annals of the Four Masters, the Annals of Ulster, the Annals of Innisfallen and the Annales Cambriae or Annals of Wales, one of the earliest sources for King Arthur. The Anglo-Saxon Chronicle is also in annalistic, year-by-year form.
