Here Virgo was at the Full Moon with 5 turtle glyphs at the end of the text on side a. The beginning of side b was at the First Point of Aries with a 6th turtle (which we possibly should connect with the fact that in 3 out of 5 surfing days Ira did not accompany the other 5 explorers when they acted like turtles):

Also the comparatively short K text - which runs in parallel with the G text from the beginning of its side a up to approximately the time of heliacal Antares - has turtles (honu glyphs) here:

Numbers with asterisk (*) are reconstructed by me because the glyphs appear to have been destroyed. But the idea of the creator of the text could have been to put in parallel 181 (92 + 89) glyphs with 192 glyph positions. At the time of rongorongo the right ascension distance from Aldebaran to Antares was 181 days Northern summer: 183 180 α Tauri α Scorpii 182 = 13 * 14 days Southern winter and 192 was the day number for July 11 when Antares culminated (at 21h). At the time of Bharani this culmination date had been 192 - 41 = 151 ("May 31), i.e. the day before the Explorers reached Easter Island. ... [E:17] On the twenty-fifth day of the first month (Vaitu Nui), Ira and Makoi set sail; on the first day of June ('Maro'), the bow of Ira's canoe appeared on the distant horizon, came closer and closer on its course, and sailed along, and finally (one) could see the (new home) land ...

The Earth Turtle - perhaps identified in the Mayan so-called Nunnery building - meant the 'surface of the earth':

... An iconographic study by Jeff Kowalski suggests a cosmological layout for the Nunnery. The higher placement of the North Building, with its 13 exterior doorways (reflecting the 13 layers of heaven), and the celestial serpents surmounting the huts identify it with the celestial sphere. The iconography of the West Building, with 7 exterior doorways (7 is the mystic number of the earth's surface), and figures of Pawahtun - the earth god as a turtle - indicate this to be the Middleworld, the place of the sun's descent into the Underworld. The East Building has mosaic elements reflecting the old war cult of Teotihuacan, where tradition had it that the sun was born; thus, this may also be Middleworld, the place of the rising sun. Finally, the South Building has 9 exterior doorways (the Underworld or Xibalba had 9 layers), and has the lowest placement in the compex; it thus seems to be associated with death and the nether regions ...

I have earlier been inclined to connect this Pawahtun turtle with the equinoxes:

... In the most general sense, the 'earth' was the ideal plane laid through the ecliptic. The 'dry earth', in a more specific sense, was the ideal plane going through the celestial equator. The equator thus divided two halves of the zodiac which ran on the ecliptic, 23 ½º inclined to the equator, one half being 'dry land' (the northern band of the zodiac, reaching from the vernal to the autumnal equinox), the other representing the 'waters below' the equinoctial plane (the southern arc of the zodiac, reaching from the autumnal equinox, via the winter solstice, to the vernal equinox. The terms 'vernal equinox', 'winter solstice', etc., are used intentionally because myth deals with time, periods of time which correspond to angular measures, and not with tracts in space ...

However, the Mayas had a turtle which appears to prove it primarily was the surface as defined by the sky equator (between the upper and lower sky shells).

Furthermore, the Child of Waters (θ Virginis) was above the ecliptic but below 0º - i.e. presumably 'down in the cup of water'.

Both the Orion and Virgo were great ancient constellations straddling the declination line of 0°. But of course there must have been a time when also Spica had been at 0h. Or rather at midsummer:

... The Mnajdra Temple is located on Malta and very ancient, dating to the time before the pyramids. Marija Gimbutas: 'To sleep within the Goddess's womb was to die and to come to life anew'. In a system of reincarnation the old one must die in order to be reborn, of course. At midsummer Sun comes to a standstill, and this must therefore be an occasion when the 'flame of life' had to be transported into a new body.

... Then I become aware of ... a presence - a faint, ghostly glimmering, like moonglow, that has appeared on the solstice stone. I don't know how long it lasts, a second or two only I would guess, but while it is there it seems less like a projection - which I know it to be - than something immanent within the stone itself. And it seems to function as a herald for it fades almost as soon as it has appeared and in its place the full effect snaps on - instantaneously. It wasn't there, and then it's there. As Chris had described, the effect does curiously resemble a poleaxe, or a flag on a pole, and consists of a 'shaft', narrow at the base but widening a little towards the top, running up the left hand side of the solstice stone, surmounted by a right-facing 'head' or 'flag'. An instant later an almond-shaped spot of light, like an eye, appears a few centimeters to the right of the 'flag' and the effect is complete. Weirdly - I do not claim it has any significance - this flag-on-a-pole symbol is the ancient Egyptian hieroglyph neter, meaning 'god', or 'a god' - and not to be understood at all in the Judaeo-Christian usage of that word but rather as a reference to one of the supernatural powers or principles that guide and balance the universe. Manifested here, in this strange Stone Age temple, it glows, as though lit by inner fire.'

Neter, the Egyptian hieroglyph for 'God', could be equivalent to the toki type of glyph:

neter	toki	Ga2-1

Toki. Small basalt axe. Vanaga. Stone adze. Van Tilburg. Ha'amoe ra'a toki = 'Put the adze to sleep' (i.e. hide it in the temple during the night). Barthel. Month of the ancient Rapanui calendar. Fedorova according to Fischer. To'i. T. Stone adze (e to'i purepure = with the wounderful adze). Henry. The Araukan Indians in the coastal area of northern Chile, have customs similar to those on the Marquesas and in both areas toki means adze according to José Imbelloni. The Araukans also called their chief of war toki and the ceremonial adze symbolized his function and was exhibited at the outbreak of war. In Polynesia Toki was the name of a chief elevated by the Gods and his sign was the blade of a toki. Fraser. Axe, stone hatchet, stone tool ...; maea toki, hard slates, black, red, and gray, used for axes T. P Pau.: toki, to strike, the edge of tools, an iron hatchet. Mgv.: toki, an adze. Mq.: toki, axe, hatchet. Ta.: toi, axe. Churchill. A Maori saying: he iti toki, e rite ana ki te tangata = though the adze be small, yet does it equal a man. (Starzecka)

Counting from Ga2-1, where Canopus rose heliacally, to Spica in Virgo the distance was *202 - *95 = *107 days (= 4 * 118 - 365). I.e., 107 precessional days before the time of rongorongo Ana-roto would have been around where Canopus now was.

And at that ancient time Canopus would have risen with the Sun in around day 175 (June 25) - 107 = 68, but rather regarded to be in day 175 - 107 + 16 = 84 (Julian equinox), because we can guess that at that ancient time it was rather the return of Canopus to visibility which counted.

... She planted her potatoes 7 in a row, placing her foot in front of her as a measure from one potato to the next. Then she marked the place with a bean - which would also give nourishment to the surrounding potatoes. Next she changed variety and planted 7 more followed by another bean, and this was the pattern she followed until all her 214 varieties had been put down in their proper places. She had drawn a map which she followed and from where each sort of potato could be located at the proper time for its harvest.

... As has already been mentioned, the Delphians worshipped Dionysus once a year as the new-born child, Liknites, 'the Child in the Harvest Basket', which was a shovel-shaped basket of rush and osier used as a harvest basket, a cradle, a manger, and a winnowing-fan for tossing the grain up into the air against the wind, to separate it from the chaff. The worship of the Divine Child was established in Minoan Crete, its most famous early home in Europe. In 1903, on the site of the temple of Dictaean Zeues - the Zeus who was yearly born in Rhea's cave at Dicte near Cnossos, where Pythagoras spent 'thrice nine hallowed days' [27] of his initiation - was found a Greek hymn which seems to preserve the original Minoan formula in which the gypsum-powdered, sword-dancing Curetes, or tutors, saluted the Child at his birthday feast. In it he is hailed as 'the Cronian one' who comes yearly to Dicte mounted on a sow and escorted by a spirit-throng, and begged for peace and plenty as a reward for their joyful leaps ...

... The leap day was introduced as part of the Julian reform. The day following the Terminalia (February 23) was doubled, forming the bis sextum - literally 'double sixth', since February 24 was 'the sixth day before the Kalends of March' using Roman inclusive counting (March 1 was the 'first day'). Although exceptions exist, the first day of the bis sextum (February 24) was usually regarded as the intercalated or 'bissextile' day since the third century. February 29 came to be regarded as the leap day when the Roman system of numbering days was replaced by sequential numbering in the late Middle Ages ...

... In the inscriptions of Dendera, published by Dümichen, the goddess Hathor is called 'lady of every joy'. For once, Dümichen adds: Literally ... 'the lady of every heart circuit'. This is not to say that the Egyptians had discovered the circulation of the blood. But the determinative sign for 'heart' often figures as the plumb bob at the end of a plumb line coming from a well-known astronomical or surveying device, the merkhet. Evidently, 'heart' is something very specific, as it were the 'center of gravity' ... See Aeg.Wb. 2, pp. 55f. for sign of the heart (ib) as expressing generally 'the middle, the center'.

And this may lead in quite another direction. The Arabs preserved a name for Canopus - besides calling the star Kalb at-tai-man ('heart of the south') ... Suhail el-wezn, 'Canopus Ponderosus', the heavy-weighing Canopus, a name promptly declared meaningless by the experts, but which could well have belonged to an archaic system in which Canopus was the weight at the end of the plumb line, as befitted its important position as a heavy star at the South Pole of the 'waters below'. Here is a chain of inferences which might or might not be valid, but it is allowable to test it, and no inference at all would come from the 'lady of every joy'. The line seems to state that Hathor (= Hat Hor, 'House of Horus') 'rules' the revolution of a specific celestial body - whether or not Canopus is alluded to - or, if we can trust the translation 'every', the revolution of all celestial bodies. As concerns the identity of the ruling lady, the greater possibility speaks for Sirius, but Venus cannot be excluded; in Mexico, too, Venus is called 'heart of the earth' ...

There was a leather thong leading up from Spica to the Fox star in Ursa Major and there could have been another line leading from Canopus to Spica.

91 (= 107 - 16) precessional days earlier than the time of rongorongo Canopus would have been around the northern spring equinox and this could explain why he drank up all the waters (of winter):

... The Pythagoreans make Phaeton fall into Eridanus, burning part of its water, and glowing still at the time when the Argonauts passed by. Ovid stated that since the fall the Nile hides its sources. Rigveda 9.73.3 says that the Great Varuna has hidden the ocean. The Mahabharata tells in its own style why the 'heavenly Ganga' had to be brought down. At the end of the Golden Age (Krita Yuga) a class of Asura who had fought against the 'gods' hid themselves in the ocean where the gods could not reach them, and planned to overthrow the government. So the gods implored Agastya (Canopus, alpha Carinae = Eridu) for help. The great Rishi did as he was bidden, drank up the water of the ocean, and thus laid bare the enemies, who were then slain by the gods. But now, there was no ocean anymore! Implored by the gods to fill the sea again, the Holy One replied: 'That water in sooth hath been digested by me. Some other expedient, therefore, must be thought of by you, if ye desire to make endeavour to fill the ocean ...

 

... In Hindu tradition, Rahu is a cut-off head of an asura, that swallows the sun or the moon causing eclipses. He is depicted in art as a serpent with no body riding a chariot drawn by eight [8] black horses ... According to legend, during the Samudra manthan, the asura Rahu drank some of the divine nectar. Sun and moon realized it and they alerted Mohini (the female avatar of Vishnu). Before the nectar could pass his throat, Mohini cut off his head. The head, however, remained immortal. It is believed that this immortal head occasionally swallows the sun or the moon, causing eclipses. Then, the sun or moon passes through the opening at the neck, ending the eclipse ...
