equality cannot be assured in the way Neugebauer tried to prove it, because the particular Metonic 19-year lunar cycle of the not-dated manuscript concerning AD 311-369 he staged, could have been obtained afterwards by simply extrapolating from the fifth century 7980-year framework. Moreover, Neugebauer not only ignored the difference between the classical Alexandrian and the Festal Index 19-year lunar cycle, but also kept us guessing about, at least refrained from showing, the (crucial) position of the saltus in the particular Metonic 19-year lunar cycle in question.

theoretical lower limit date for all of his dates of Paschal full moon. As a matter of fact, the corresponding de facto lower limit date (necessarily being either 22 or 23 March) is not 22 but 23 March, which easily can be derived from Anatolius’ Paschal table. In contrast, he used not only Ptolemy's but also the Roman equinox, March 25, in his Paschal table.

Considering that only around AD 400 Annianus obtained his classical Alexandrian version of the Metonic 19-year lunar cycle by adapting 415:
Anatolius describes the vernal equinox as a section of the first zodiacal sign from March 22 to 25. Although he defines March 22 as the Sun's entry into the first sign, he never defines it as his equinox, but as Ptolemy's equinox. This does not exclude that in reality he used Ptolemy's equinox as the

The dates of the ultimately resulting classical Alexandrian 19-year lunar cycle have recently appeared to be advanced by about two days over the dates of Anatolius’ 19-year lunar cycle.
