Reconstructing Metonic 19‑year Lunar Cycles
(on the basis of NASA’s Six Millennium Catalog of Phases of the Moon)
This book (ISBN 9789090324678), available via this website, 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 rised shortly after AD 250 in Alexandria (Egypt) to ultimately (in AD 1582, turning point in the history of chronology) flow into a modern way of determining (Gregorian calendar) dates of Easter, how of old dates of Paschal Sunday depend on phases of the moon and, on the basis of NASA’s Six Millennium Catalog of Phases of the Moon, how recently both lost Metonic 19‑year lunar cycles constructed in Alexandria before the first council of Nicaea (in AD 325, turning point in the history of Christianity) were reconstructed.
