In the 'Excursion' searching for kava in G a mauga glyph with a little 'eye' (Ga5-19) was found in the middle of the season of growing sun. Ga1-26 and Gb1-6 (viri variants) are marking the lowest and highest positions of the sun. As was explained earlier:

	102			102
Ga1-26		Ga5-19	Ga5-20		Gb1-4	Gb1-5	Gb1-6
208 = 8 * 26

... With the 1st half of the year 'being born' at Ga1-26 high summer will be illustrated in Gb1-5 as a fully grown and standing tagata. Mauga in Ga5-19 can mark the end of the 1st calendar quarter. It stands at the center of the 19th period and also has ordinal number 19 ...

The little 'eye' at right (forward in time) - we now can understand - indicates how light is arriving. The darkness of mauga, the last glyph of the 1st quarter, is changed into the light of the 2nd quarter. Summer enters and winter leaves.
