The form of Aa2-4 makes it into a variant of vero, which Metoro probably observed, because he said vero at the following glyph:

		Nuku erua means two 'lands'.
Aa2-3	Aa2-4	Maybe the two halves ('lands') of the year are depicted: The first half in form of a low flying 'hua' together with (below, later) a 'dry land head' with a single mata in front. In Aa2-4 (where 2 * 4 = 8) light has evidently left (Te Pei) and at the bottom is a 'water droplet'. If time runs downwards it ends in water.
eko te nuku erua - no te tagata
		Vero tahi means 'first spear' and hupee mucus.
Aa2-5	Aa2-6 (96)	A spear is thrown in a quick movement of the arm (rima) and the king is induced to fast reaction. If he survives and reaches the state of 'fully grown' (tagata), he will no longer be as quick as the eye.
vero tahi	ma te hupee

I have named a glyph type hupee and Aa2-6 will be discussed more at that point in the dictionary.

A glyph of beginning (Aa2-5) is followed by a glyph signifying end (Aa2-6). But in the next pair the order is reversed. The glyph at left has at left (in the past) a 'child' with tagata at right, while the glyph at right has tagata at left and the 'child' at right:

		Pu means 'hole' and also signifies 'origin'. Ipu is the Tahitian version of hipu, calabash. Mahigo is 'offspring'.
Aa2-7	Aa2-8	The limbs of tagata in Aa2-7 are 'cut off' at right and there is no mata at right. It is Monday, a final day. The hakaturou sign at right in Aa2-8 begins from nothing.
ka pu te ipu	ka pu - i te mahigo

Significantly Aa2-7--8 are 'double-sign' glyphs, they indicate both what was and what will come. They are at the threshold from one 'room' to another (like Janus). In other words, the 4 pairs could very well represent the 4 'quarters' of the Sun:

		crack in front
Aa2-1	Aa2-2
		oval and triangle
Aa2-3	Aa2-4
		beginning respecively end
Aa2-5	Aa2-6
		'hua' at left respectively at right
Aa2-7	Aa2-8

In Aa2-1 tagata (the old year) stands at winter solstice (mata both at left and at right) and his 'fist' in front will be reborn as a new year.

At Aa2-6 (where 2 * 6 = 12) comes next tagata, this one presumably also standing at the end of a year. His left arm together with the left part of his headgear may signify that the 2nd part of autumn is now in the past.

Aa2-7--8 would then be a 4th 'quarter' (where each 'quarter' would represent 16 / 4 = 4 periods). Old Sun has left and Moon has 2 'faces', her own (waxing) respectively the 'face' of her child' (Mars). The hipu sign is formed like a hanging breast, surely waxing Moon (at full moon the 'sucking' will be over, Omotohi). The child must be weaned because Moon will not support him during waning. Weaning and waning are related words.

The above suggested 'year' is not the whole year but only the 'year' which begins where Mars (spring) is ending. If I am right, then line Aa1 could represent the first half of the year and line Aa2 the 2nd half.
