The number of glyphs on the G tablet is 471, which is 1 less than 8 * 59 = 472, perhaps in order to point at 3 / 2 * 100π. The origin of something is not visible (hidden) and this can account for the necessity to cover up (puo) the opening (gateway) through which the front side of the text emerges.

Puo

(Also pu'a); pu'o nua, one who covers himself with a nua (blanket), that is to say, a human being. Vanaga.

1. To dress, to clothe, to dress the hair; puoa, clothed; puoa tahaga, always dressed. 2. To daub, to besmear (cf. pua 2); puo ei oone, to daub with dirt, to smear. 3. Ata puo, to hill up a plant. Churchill.

The 'rainy Hyades' was once a proverbial expression:

"The Greeks knew them as Ύάδεσ, which because [probably: became] 'Hyades' with the cultured Latins, supposed by some to be from ϋειν, 'to rain', referring to the wet period attending their morning and evening setting in the latter parts of May and November; and this is their universal character in the literature of all ages." (Allen)

The implication is that Sun did not shine when he was in the Hyades, he was not visible.

Perhaps the beginning of side a on the K tablet is not a continuation of the end of its b side. But we can see a pair of partially visible puo glyphs:


Ka1-1	Ka1-2	Ka1-3	Ka1-4	Ka1-5	Ka1-6
Hyadum I (63.4)	Hyadum II (64.2)

I have here tried to connect the first pair of glyphs with the Hyadum twins (γ Tauri and δ¹ Tauri) not only because of the similarity with the beginning of the G text but also because of their names. There are several other Hyades stars to choose from but names were once more important than our modern minds can fathom.

"The mythographers were massively confused about the names and even the number of the Hyades. They are variously described as being five or seven in number. The Greek astronomer Ptolemy listed five Hyades in his star catalogue. Hyginus alone gives four different lists of their names, none of which agrees completely with the list of five originally given by Hesiod, viz: Phaesyle, Coronis, Cleia, Phaeo and Eudore."

I have kept the right ascension numbers for the stars from my reconstruction of how to read G - the precession moves the stars so slowly ahead in the year that for the rongorongo texts we can assume their places in the year to be fixed.

Furthermore, in the opinion of Fischer the London Tablet (K) was made after the ariki Gaara died (around 1859).

On the other hand I have so far not carried over to K from the G text the Gregorian and Arabic manzil dates. The same star map can be used in different ways, not necessarily for watching the stars in the sky in the early mornings. It can, for instance, be done also in the evenings, or at midnight.
