Any codex of Beda Venerabilis' Easter table is normally found together with a codex of his "De temporum ratione". Bede's Easter table, being an exact extension of Dionysius Exiguus' Paschal table and covering the time interval AD 532–1063, contains a 532-year Paschal cycle based on the so-called classical Alexandrian 19-year lunar cycle, being the close variant of bishop Theophilus' 19-year lunar cycle proposed by Annianus and adopted by bishop Cyril of Alexandria around AD 425. The ultimate similar (but rather different) predecessor of this Metonic 19-year lunar cycle is the one invented by Anatolius around AD 260.
