Reconstructing Metonic 19‑year Lunar Cycles

(on the basis of NASA’s Six Millennium Catalog of Phases of the Moon)

This groundbreaking book on early Alexandrian Paschal reckoning is available via this website. It explains, by following the mainstream of the history of the computus paschalis developed from early in the third century for the purpose of determining (Alexandrian or Julian calendar) dates of Paschal Sunday, which rose shortly after AD 250 in Alexandria (Egypt) to ultimately in AD 1582 (turning point in the history of chronology) flow into a more realistic method for determining (Gregorian calendar) dates of Easter, how at the time dates of Paschal Sunday depended on phases of the moon and how recently both lost Metonic 19‑year lunar cycles constructed in Alexandria before the council of Nicaea in AD 325 (turning point in the history of Christianity) were reconstructed on the basis of the Six Millennium Catalog of Phases of the Moon compiled by NASA eclipse expert Fred Espenak.
