Gb6-26

Counted from Ga1-1 the ordinal number of the glyph in the text is 408. Counted from the empty glyph space before Ga1-1 the number is 409. In the latter case we could count 40 * 9 = 360 and in the former case we could count 320 = 40 * 8.

Counted from day 354 (December 20) this was 408 - 392 = 409 - 393 = 16 days later - as if there had been some significant heliacal star which would return to visibility here, maybe one of those I have listed at Gb6-10:

Initially I had used the equation Tagaroa Uri = 'October. But then I realized the lengths of certain months had to be shortened in order to agree with the measures in the Pre-Julian calendar, which meant for instance an addition with 5 days when stating the dates in the month Tagaroa Uri. However, the day numbers and the right ascension day numbers did not change (cfr above). This meant the day of the solstice at the time of rongorongo (December 21) could be calendar day 280 (Ko Ruti 6 instead of Ko Ruti 1).

December 21 (355) - 280 (Ko Ruti 6) = 75 days counted from 0h, a number agreeing with where in rongorongo times Haedus II rose with the Sun.

Another way of looking at it is to perceive 0h as 11 + 80 = 91 days after December 20. 354 + 91 - 365 = 80. From the Hyades Gate (Hyades II) to Haedus II (at the Hole in the Fence of the Hairy Winter Goat, Capella, α Aurigae) there were 75 - 64 = 11 days. It seems more rational to count time from the cardinal points of the Sun than to use the Gregorian (Julian) structure. Gb5-26 (150) is 29 glyphs earlier than Gb6-26 (179) and a right ascension line from Rigel up to Capella may have been 2 * 75 = 150 = 300 / 2 days from the beginning of side b:

I am here using the expression 'fence' because the 9th month was Ko Koró:

Koro 1. Father (seems to be an older word than matu'a tamâroa). 2. Feast, festival; this is the generic term for feasts featuring songs and banquetting; koro hakaopo, feast where men and women danced. 3. When (also: ana koro); ana koro oho au ki Anakena, when I go to Anakena; in case, koro haga e îa, in case he wants it. Vanaga. If. Korokoro, To clack the tongue (kurukuru). Churchill. Ma.: aokoro, pukoro, a halo around the moon. Vi.: virikoro, a circle around the moon. There is a complete accord from Efaté through Viti to Polynesia in the main use of this stem and in the particular use which is set to itself apart. In Efaté koro answers equally well for fence and for halo. In the marked advance which characterizes social life in Viti and among the Maori the need has been felt of qualifying koro in some distinctive manner when its reference is celestial. In Viti virimbai has the meaning of putting up a fence (mbai fence); viri does not appear independently in this use, but it is undoubtedly homogenetic with Samoan vili, which has a basic meaning of going around; virikoro then signifies the ring-fence-that-goes-around, sc. the moon. In the Maori, aokoro is the cloud-fence. Churchill 2.

Korohua Old man; also used jokingly or affectionately of any adult man. Vanaga.

Koroua Decrepit, old age, worn with age. Churchill.

Supposing March 21 was at Gb6-26, what heliacal dates could then be extrapolated backwards in time to the day of the return of the explorers to their homeland in Tagaroa Uri 30?

If they returned in Tagaroa Uri 30 and if this was at mauga (last) in Gb5-28 (381), then we could count 408 - 381 = 27 and then March 21 (80) - 27 = 53 (February 22). Which means the headless figure in the following day should be at Terminalia:
