5. The name Tree Climber felt reasonable also because the stars which I so far had connected with glyphs were rising later and later in spring (north of the equator). And moving higher and higher up from line a1 right at the bottom of side a was like climbing a tree.

However, if the current right ascension values for the stars (2000 years from the beginning of the age of Pisces) are those intended to be understood by the creator of the G text, then midsummer - or rather winter solstice according to the season on Easter Island - would come about a month earlier than the henua calendar:

27 28
Ga1-27 (500) Ga1-28 (**473)
winter solstice
Beginning of the henua calendar.
Ga2-27 (*122) Ga2-28 (59) Ga2-29
Naos (122.3)  Heap of Fuel (123.1)  Tegmine (124.3)

The necessity to count is here coming to the surface. We can hardly avoid perceiving number 500 at Ga1-27 as an intended effect by the creator of the text. I have counted beyond the last glyph on side b (number 472) and then Ga1-27 will be number 500.

Gradually I have come to adopt three counting procedures in parallel:

Counting procedures: Sign conventions (examples):
Counting glyphs from Gb8-30. Ga2-28 (59) means Ga2-28 is glyph number 59. Ga1-27 (500) means Ga2-28 is glyph number 500 (if continuing counting beyond 472), i.e. 500 = 28 + 472.
Counting glyphs from Gb6-25 at 0h. Ga2-27 (*122) means Ga2-27 is glyph number 122 - the result of adding 64 (to the end of side b) and 29 (from Gb8-30).
Counting glyphs from Ga1-28 (June 22). Ga1-28 (**473) means Ga1-18 is glyph number 473 counted from Ga1-28, i.e. its number could equally well have been written (**1).

The numbers derived from these three procedures are interconnected, for instance is *250 = 186 + 64 = **158 (= 186 - 28).

22 29 127
Ga1-4 (*69) Ga1-27 (*92) Ga1-28 (**1) Ga2-27 (**31) Ga7-16
54 (= 2 * 27) 128 (= 2 * 64)
182

27 = 3 * 3 * 3 and 64 = 4 * 4 * 4. If we add 2 * 125 (or 250 glyphs) to the position of mago in Ga7-16 (*250) we will reach *500 (i.e. the glyph at position 436).

248
Ga7-16 (*250) Gb7-24 Gb7-25 (436) Gb7-26
Antares (250.1)  Polaris (435.6), Baten Kaitos (435.6), Metallah (435.9), Segin (436.2), Mesarthim (436.2), Sheratan (436.4)

Maybe such number 'jokes' were invented far earlier than when the creator of the G text was born. They could originate from ancient astronomers counting, counting, and recounting.

The exercise indicates we should not regard the distance between Aldebaran and Antares as 181 days. The proper measure should be 182 (or 364 / 2) days. The number play alludes to the famous and certainly already long before written history discovered Pythagoras' equation 3 * 3 + 4 * 4 = 5 * 5.

Once I myself found a similar formula: 10² + 11² + 12² = 365 = 13² + 14². Order rules the heavens, therefore we must avoid chaos down on earth.
