Ultimately Anatolius’
lunar cycle (1) has appeared to be different from the about ten years older
proto‑Alexandrian lunar cycle (0): in fact these two lost 19‑lunar cycles differ in only 1 out of
their 19 different calendar dates. Furthermore, the third of the
three (lost) ante‑Nicene Alexandrian lunar cycles,
the about fifty years younger archetypal
Alexandrian lunar cycle (2), and the more than a century younger three (well‑known) post‑Nicene Alexandrian lunar cycles
(3), (4), and (5) are not very different from each other. Observing Table 20 of
the book in question we note that between on the one hand (0) and (1) and on
the other (2), (3), (4), and (5) there is a (apparently ante-Nicene)
gap of on average just over 2 days, referred to as the ante-Nicene Alexandrian 2-day gap.
