3. The Gemini constellation should be depicted as a pair of twins with a string instrument, as e.g. in Argelander's version:

Lyra (here by Hevelius) is the only other constellation with a string instrument in its center:

I suggest this is no coincidence but a Sign meaning Gemini and Lyra are to be considered together. It is another example of the kind of similarity which initially draw my attention to Ga1-4 and Ga7-16:

180
Ga1-4 (*69) Ga7-16 (*250)
Aldebaran Antares

The curved 'tail' in Ga2-11 is different from that in Ga7-16 and there may be an allusion to a fish hook in the hakaturou type of glyph:

176
Ga2-11 Ga8-15
ω Gemini Vega

(Alfred Métraux, The Ethnology of Easter Island.)

If Vega is close to 'the Apex of the Sun's Way', then Sun maybe once in a year had to be 'drawn up' to Lyra like a fish?

Today our north star is Polaris, the 10th and last of the Tahitian 'star pillars', and it can hardly be a coincidence that this is the pillar 'to fish by':
