"Long ago in the very beginning of time there dwelt within a shell an infant god whose name was Ta'aroa. He was Ta'aroa the unique one, the ancestor of all gods, the creator of the universe whose natures were myriad, whose backbone was the ridgepole of the world, whose ribs were its supporters. The shell was called Rumia, Upset.

Becoming aware at last of his own existence and oppressed by a yearning loneliness Ta'aroa broke open his shell and, looking out, beheld the black limitless expanse of empty space. Hopefully, he shouted, but no voice answered him. He was alone in the vast cosmos. Within the broken Rumia he grew a new shell to shut out the primeval void.

The sun was held down close above the slowly evolving earth by the Great Octopus, Tumu-rai-fenua, Foundation of Heaven and Earth, who lived in the primeval waters on which the earth floated. One of his arms was to the north, one to the south, one to the east and another to the west. With these vast arms he held the sky, the shell Rumia, close down against the earth.

Meanwhile on the earth itself various generations of rocks were born, one after the other; then sand appeared. Roots were born and as they spread they held the sand together and the land became firm.

Ta'aroa sat in his heaven above the earth and conjured forth gods with his words. When he shook off his red and yellow feathers they drifted down and became trees.

He created the first parents, Tumu-nui, Great Foundation, to be the husband, and Paparaharaha, Stratum Rock, to be the wife. He put the very essence of himself into their creation; yet when he commanded them to wed, each refused to go to the other. So Ta'aroa created other gods and Atea, Bright Expanse, the Sky-goddess, who dwelt in darkness in the confined sky Rumia.

By Papa-tuoi, Thin Earth, Atea was the mother of children who became artisans for Rai-tupua-nui, Great-Sky-builder. They assisted him in erecting the ten heavens above the earth. In the highest of these dwelt the god Tane, so it was called the Sky-of-the-sacred-omens of Tane and Sky-of-the-water-of-life of Tane. The next highest heaven was called Hiro's Sky-of-prophets.

Atea then became the wife of Rua-tupua-nui, Source of Great Growth, and they became the parents of all the celestial beings, first the shooting stars, then the Moon and the Sun, next the comets, then the multitude of stars and constellations, and finally the bright and dark nebulae.

When this tremendous task had been accomplished Atea took a third husband, Fa'a-hotu, Make Fruitful. Then occurred a curious event. Whether Atea had wearied of bringing forth offspring we are not told, but certain it is that Atea and her husband Fa'a-hotu exchanged sexes. Then the [male] eyes of Atea glanced down at those of his wife Hotu and they begat Ru. It was this Ru who explored the whole earth and divided it into north, south, east, and west." (Makemson)

We begin by recapitulating how periods 5-6 were listed in the ragi 'chapter':

Following the link 'the beginning of summer' a page commented upon the resemblance between Sb2-8

and the contents in period 6:

We can see a relationship between period 6 in the E calendar and Sb2-8. It remains to be shown the further relationship between pure and two bent henua.

Possibly these bent henua are alluding to the myth about Tagaroa (sitting lonely in the shell Rumia in the dark beginning, shouting without anybody responding to his call). The body of Tagaroa was like the dome of the sky, boat-shaped like a hare paega, like one of the empty halves of a bivalve mollusc. The bent henua could depict the shape of Tagaroa.

The argument is obviously very weak, yet Metoro gives some strength to it by way of his words at Eb3-15:

Eb3-13	Eb3-14	Eb3-15	Eb3-16
kua tua te vaivai	rima	kua tuo te tino	te rima - te kihikihi

This is the only time he used the word tuo in his readings for Bishop Jaussen. It means 'to cry out loudly', 'to cry with a loud voice', or 'to speak long without an answer', exactly what the lonely Tagaroa did. Indeed quite remarkable to have a special word for that!

It might be a coincidence of course. But Metoro also said tino, a word meaning 'body', 'tree trunk', 'keel of a boat' etc. I.e., kua tuo te tino ought to mean 'the body (possibly of Tagaroa) was crying out without anybody responding'.
