æstate: similiter & in reliquis anni temporibus eadem sacrificia cadere.
Hoc enim putabant acceptum & gratum esse Diis. Hoc autem aliter fieri non
posset nisi conversiones solstitiales & æquinoctia in iisdem Zodiaci locis
fierent. Secundum Lunam vero dies agere est tale ut congruant cum Lunæ
illuminationibus appellationes dierum. Nam a Lunæ illuminationibus
appellationes dierum sunt denominatæ. In qua enim die Luna apparet nova, ea
per Synalœphen, seu compositionem νεομηνια id est, Novilunium appellatur.
In qua vero die secundam facit apparitionem, eam secundam Lunam vocarunt.
Apparitionem Lunæ quæ circa medium mensis fit, ab ipso eventu διχομηνιαν,
id est medietatem mensis nominarunt. Ac summatim, omnes dies a Lunæ

ultima sit, ab ipso eventu τριακαδα vocarunt_.

The ancient Calendar year of the _Greeks_ consisted therefore of twelve
Lunar months, and every month of thirty days: and these years and months
they corrected from time to time, by the courses of the Sun and Moon,
omitting a day or two in the month, as often as they found the month too

to this year of the _Greeks_, in his Parable of one father who had twelve

_Thales_ [53] called the last day of the month τριακαδα, the thirtieth: and
_Solon_ counted the ten last days of the month backward from the thirtieth,
calling that day ενην και νεαν, the old and the new, or the last day of the
old month and the first day of the new: for he introduced months of 29 and
30 days alternately, making the thirtieth day of every other month to be
the first day of the next month.

To the twelve Lunar months [54] the ancient _Greeks_ added a thirteenth,
