 Of course, this does not exclude that the (in principle tentative) version constructed in the first quarter of the fourth century could be, by chance, equal to Annianus’ ultimately definitive one.In any case, this possible 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.
