Table 8: Comparing
the two ante-Nicene and the three
post-Nicene Alexandrian Metonic 19‑year lunar cycles to each other |
Anatolius’ 19-year lunar cycle is the lost very first Metonic 19‑year lunar cycle, invented by the great Alexandrian computist Anatolius before he became bishop of Laodicea in AD 268. The archetypal Alexandrian 19-year lunar cycle is the lost ante-Nicene common archetype of the three well-known post-Nicene Alexandrian Metonic 19‑year lunar cycles. Annianus’ 19-year lunar cycle is the well-known classical Alexandrian 19-year lunar cycle opted for by the Alexandrian monk and great computist Annianus (around AD 412) which forms the Metonic basic structure both of Dionysius Exiguus’ Paschal table (AD 525) and of the Easter table of Beda Venerabilis (AD 725). We observe that the 2-day gap between on the one hand Anatolius’ 19-year lunar cycle and on the other hand the other four Alexandrian Metonic 19-year lunar cycles dates from before the first council of Nicaea (AD 325).
