Споры о возрасте мира в Византии VII–XI вв. (О трех мировых эрах: александрийской, «протовизантийской» и византийской)

— Byzantine authors hesitated between Alexandrine and «Byzantine» systems even after the former had been abolished — its survival was caused by the «Easter Tables» and by the mystical significance of 5500 years which had allegedly elapsed between Adam and Christ. The unresolved nature of the chronological question in Byzantium contributed to the decline of the genre of chronography. [Ivanov]
