By the way, also the arrow of Sagittarius is oriented in the forward direction, in contrast to e.g. the 'head' of Leo. However, possibly it is the tuft of hair at the end of his tail, Denebola. The form of the Lion's tail is similar to that of the hair lock of Harpocrates, though reversed. Counting from Capricorn there are 3 months 'in the Sea' followed by 5 months of 'Sun-lit Land'. From Virgo to the the end of the 'Land' there are another 4 months. 3 + 4 + 5 = 12.

But far south, below the tropical belt, the signs on the skirt of Mother Earth (Pachamama) - the 'watery eyes' - ought to be used instead. So I think. However, in rongorongo glyphs the inside is not visible and no pupil can be drawn. Though in stone sculpture it was evidently possible:

5. The 'residences' of Hotua Matua, the sun king on Easter Island (even if he was a real historical person his characteristics and deeds became like that of the sun, hiding his true person), presumably were connected with his wife, queen Vakai, who over time became a moon queen. Sun forms a pair with the moon.

Ships are female according to ancient tradition, and so are houses, I suggest. Vakai is a name which begins with vaka = canoe. An instructive stone sculpture (designed to be a myth map) has a hare paega on the back of what probably is sun as a fish:

The front of the fish is the male sun, while the back is its female part. Gods can be both male and female and change sex according to the location in the cycle.

Working with cloth and making white tapa was the business of women, and one of them, Hina, was dispatched of to the moon because she disturbed the gods by her beating tapa. Ships, houses, the back side, darkness, moon, birth, death - and cloth were female. The hau tea glyph must therefore be female - given the name of the glyph. Tea means white and the moon is white.

Perhaps the idea behind the stone fish was to depict the Cetus creature:

I think it is significant that the tail of Cetus has a hole right through. In contrast the stone fish from Easter Island has a hole which serves as an earth oven (open only upwards)
