My imagination has found a Mermaid's Purse, the egg case of a shark, at the center of ika hiku glyphs:   ika hiku There is evidence of a connection between shark glyphs (vaha mea, mago) and ika hiku glyphs. For instance are there 6 lunar months from vaha mea in Ga1-4 to ika hiku in Ga7-12.  180    180 Ga1-4 (5) Ga7-16 (186) Gb8-30 (1) Ga7-12 (182) vaha mea mago puo ika hiku 182 days 182 days Studies of the G and Q texts suggest ika hiku glyphs appear beyond the spring sun 'half year', e.g.: 258 Gb6-26 (1) Ga7-26 (260) Ga7-27 The '2nd half year' is ruled by the moon, and ika hiku tend to come in pairs (in the same way as moon has two 'faces'). Ika hiku in Ga7-27 is day number 197 counted from Gb8-30. In Q a vaha mea shark has a position counted from Qa1-1 equal to the lunar station of Te Pou (Sirius), which generates day number 197: *Qa7-11 *Qa7-12 (266) 197 = 266 / 2 + 64 Possibly there was a 'shark year' based on 2 * 197 = 394 days: Gb6-5 Gb6-6 Gb6-7 (390) Gb6-8 Gb6-9 Gb6-10 Gb6-11 (394) Gb6-12 Gb6-13 Gb6-14 Gb6-15 Gb6-16 (399) 394 - 266 = 2 * 64. In some complicated way number 64 has a key role in the number system of rongorongo.

Yet, nothing is said about the 'legs' in ika hiku glyphs. *Qb6-6 shows they are not a necessary part of the glyph type, while Qa9-36 carries another type of legs than what we have seen earlier:

Qa9-36 (378)	Qb2-15	Qb2-24	*Qb6-6 (622)

They are single and their numbers suggest the sun, not the moon. But I have not in the summary page suggested ika hiku glyphs are monopolized by the moon.

*Qb6-6 has mea ke at right and the missing legs could mean it is a 'dead' ika hiku. 6 * 6 = 36 says it too.

The legs of Qa9-36 are 4 in number, as if to refer to the moon or the earth, while the pair in Qb2-15 and Qb2-24 have 6 each, as if to refer to the sun. Sun and moon together seems to be the message, a concunction.

The 4 legs of Qa9-36 are thick and the 6 of the other type threadlike. Both types are bent and cuplike, implying a female character.

The legs of ika hiku in G are quite different, they are turned the other way and look like 'feathers':

The implication is the opposite of ua (rain) signs. However, in high summer there is no rain, which could explain why the ua sign is turned 'on its back'. The empty ua is waiting for rain.

Men fall on their faces, but women seem to fall on their backs.

The numbers (4 + 4 = 8 respectively 4 + 3 = 7) both refer to the moon, I think. There are 8 weeks (when moon is shining) in a doublemonth.

4 + 3 suggests 4 * 4 + 3 * 4 = 16 + 12 = 28. We have seen that 17 is a sign for the beginning of a new period. 16 is the last night of waxing moon.

In C there are no ika hiku glyphs and no vaha mea glyphs. But there are several mago glyphs and a pair of kea glyphs:

Obviously these have much in common with Qa9-36. The twin heads made me put this type into a separate apartment when classifying glyphs.
