15
	Ga4-23	Ga4-24	Ga4-25	Ga4-26	Ga4-27

If period 29 is corresponding to the black 29th night in the month, we should try to connect the 15th period with the beginning of Waning Moon, for instance in a structure like this:

Waxing Moon			Waning Moon
30th night	13 nights	14th night	15th night	13 nights	29th night
15 nights			15 nights

Mars rules number 14 and then comes Mercury as number 15 - the pattern of the week has the strong one before the weak one. Significantly we can see a mama in Wednesday (the day of Mercury):

In the 'list' of 31 kiore-henua (and growing maro) periods in G we could, maybe, change the beginning of Waxing Moon to the 31st night, or - if we count with 192 days - even to the 32nd night. But the picture will remain the same, apparently there is a growing light followed by its waning.

This structure does not necessarily refer to a month. It can be applied to any undulating movement. Early in my studies of the rongorongo texts I became convinced these 31 periods were describing a calendar for the year. I could not prove it, though, and still the meaning is uncertain.

Let us therefore continue with a few more pages in order to see if this important question mark can be eliminated.
