4. In the view of Hevelius the Scorpion has his tail curved at right, which is the opposite to what we can see in the sky:

The reason is that Hevelius had his perspective from the outside of our star globe, with right ascension rising towards the right. His east is at right.

In G right ascension is also rising towards the right. The text is flowing towards the east and therefore we can never see a mago glyph with tail at left:

lean
	Ga2-14	Ga3-23	Ga7-16 (186)	Gb2-10
fat
	Gb6-13	Gb7-13	Gb7-16 (427)	Gb6-11

In the whole corpus of rongorongo texts there is only one exampel of a reversed mago (and typically it is in the non-orthodox P text):

Pb10-32	Pb10-33	Pb10-34	Pb10-35	Pb10-36	Pb10-37	Pb10-38
