5. The present position of Altair (α Aquilae) is 19h 48m which we can translate to (19 * 60 + 48) / 1440 * 365¼ = day number 301.3 counted from spring equinox north of the equator. To find the corresponding glyph in the text on the G tablet we should count 301 glyphs beyond Gb6-25:

63 234
Gb6-25 (*0) Gb8-30 (*64) Gb8-30 Gb1-6 Gb1-7 (237)
autumn equinox 301

We know Gb1-7 is at a cardinal point (the 1st glyph in the 2nd half of 472), and we can imagine the 'two arrows', Aagjuuk (Altair and Tarazed), are rising heliacally here to announce Sun is leaving, rushing away to reappear in the north. Tarazed (Reda) is rising at 19h 44m, 1 day earlier than Altair. I think this is a rather convincing 'proof' that my model is accurate and reliable. We have been here before, though, cfr at Sirrah:

... Remarkably the current right ascension of Reda, 19h 44m = 1184 minutes, gives rise not only to day number 300.3 counted from equinox but also to the numerical magic of 118 * 4 = 472, as if the whole cycle is completed after 300 days.

The pair of stars announcing the return of Sun must have been different in ancient epochs. Castor and Pollux was probably once such a 'twin' pair.

If the heliacal rising of Cancer on Easter Island was thought to coincide with the return of Sun, then there should be a pair of prominent stars corresponding to Altair and Tarazed in the 9th hour. Counting half a year earlier than glyph number 237 leads us to search for such a pair of glyphs close to number 237 - 182 = 55, and the obvious choice is Ga2-25--26 - but we have so far not assigned any stars to these glyphs:

Ga2-21 (52) Ga2-22 Ga2-23
Procyon (115.9) σ Gemini, Pollux (117.2) Azmidiske (118.4)
Ga2-24 Ga2-25 (*120) Ga2-26
period 1
Ga2-27 (*122) Ga2-28 Ga2-29
Naos (122.3) Heap of Fuel (123.1) Tegmine (124.3)
Ga3-1 (*125) Ga3-2 (62) Ga3-3 Ga3-4 Ga3-5
Al Tarf (125.3) Bright Fire (126.4) ο Ursa Majoris (128.4) θ Cancri (129.2)

The first prominent Cancer star to rise seems to be ω, and we can put it in parallel with Ga2-26. Or to be more exact between Ga2-26 and Ga2-27:

ω 08h 00m 55.86s 08h 00.931m 121.4
Acubens 08h 58m 29.20s 08h 58.487m 136.0
ω Cancri 5.87 25° 24′ N 07h 59m 121.4 529.4

The 'map' of G possibly says Sun suddenly arrives from northeast 64 days before spring equinox, when Naos is rising heliacally. He is 'bound' to return 6 months later:

South of the equator North of the equator
autumn equinox 266 spring equinox 80 (89)
winter solstice 358 = 266 +172 - 80 summer solstice 172 (181)
Sun returns (Naos) 23 (122) = 87 - 64 Sun leaves (Naos) 202 (211)
spring equinox 87 = 358 + (266 - 172) - 365 autumn equinox 266 (275)
summer solstice 177 = 87 + (356 - 266) = 6 * 29½ winter solstice 356 (365)
Sun leaves (Altair) 202 (301) = 23 + 179 Sun returns (Altair) 16 (25)

When the people high up in the north said Aagjuk was rising at winter solstice it cannot have been the literal truth, instead it should have happened 25 days later (like a square of Saturn).

When the people in Polynesia said Antares announced the arrival of summer it was not the literal truth, instead this star is rising heliacally 250 days after autumn equinox, and this seems to have been on a day of Jupiter and not Saturn.
