Cyril tried to oblige the pious Christian emperor Theodosius II (AD 408–450) to himself by dedicating his Paschal table to him. It is also important to note that Cyril's Paschal table was provided with a Metonic basic structure in the form of a Metonic 19-year lunar cycle adopted by him around AD 425, which was very different from the first Metonic 19-year lunar cycle invented around AD 260 by Anatolius, but exactly equal to the similar lunar cycle which had been introduced around AD 412 by Annianus; the julian equivalent of this Alexandrian lunar cycle adopted by Cyril and nowadays referred to as the 'classical (Alexandrian) 19-year lunar cycle' would only much later emerge again: a century later in Rome as the basic structure of Dionysius Exiguus’ Paschal table (AD 525) and two more centuries later in England as the one of Beda's Easter table (AD 725).
