- Beda Venerabilis' Easter cycle
In the year 616 an anonymous extended
Dionysius Exiguus' Easter tableto an Easter table concerning the years 532 up to and including 721, and it is this Easter table which about the year 650 was accepted by the church of Rome, which from the third century up till then had given preference to go on using her own, relatively inadequate, Easter tables. In the year 725 Bede (Latin name Beda Venerabilis) published a new extension of Dionysius’ Easter table to a great Easter cycle, which is periodic in its entirety and in which consequently not only the sequence of (Alexandrian) dates of Paschal full moonbut also the sequence of (Alexandrian) dates of Easter Sundayis periodic. Bede’s Easter cycle contains lunar cycles (of 19 years) as well as solar cycles (of 28 years), and therefore it has a period of 532 years. In the Byzantine empirethanks to Annianos’ Easter cycleat all times the churches were acquainted with the date of the next Easter Sunday. It is Beda Venerabilis’ Easter cycle by means of which also the churches in the part of Europe outside the Byzantine empire got that possibility.
