'Dionysius Exiguus' Easter table' was constructed in the year 525 by
Dionysius Exiguus for the years 532–626. He obtained it from an Easter table attributed to Patriarch
Cyril of Alexandria for the years 437–531. The latter was constructed around the year 440 by means of extrapolation from an Alexandrian Easter table constructed around the year 390 by Patriarch
Theophilus of Alexandria. The great historical importance of Dionysius' Easter table is bipartite: '1' from this Easter table
Bede's Easter cycle would ultimately be developed by means of which all future
Julian calendar dates of
Easter Sunday were determined (as in column G of Dionysius' table); '2' with his Easter table Dionysius introduced in passing the
Christian era (see column A of Dionysius' table) which would be developed into a full system for dating historical events by
Bede two centuries later.
