The 19‐Year Cycle of Anatolius

Show Summary Details

Preview

Anatolius, an Alexandrian scholar who became bishop of Syrian Laodicea, was the first to use the 19‐year cycle for Easter calculations. The cycle is not extant, but Eusebius quotes a substantial portion of the preface. A longer, Latin text claiming to be the preface of Anatolius may contain genuine material, but cannot be authentic in its present form. From the quotation by Eusebius and other evidence, we can conclude that the cycle of Anatolius began with epact I on 22 March. Scholars have reconstructed the cycle of Anatolius on the assumptions that he recognized 22 March as the date of the equinox and that he placed the extra day of the saltus at the end of the cycle. A reconstruction that better fits the later history of the cycle assumes 21 March as the date of the equinox and a saltus in the 12th year.

Keywords: Anatolius of Laodicea; 19‐year cycle; Latin Anatolius; equinox; saltus
