Ariga erua glyphs are variants of tagata, they depict 'persons' standing up, which presumably means they show 'fully grown' seasons. The time should basically be neither 'death' nor 'birth', instead ariga erua should be at the midstation of 'life'. The 'face' (ariga) of the sun is not seen during winter, he is only seen from the side, far away, and to see his face it must be summer. Our conclusion is that ariga erua should refer to high summer. At midsummer sun is turning around from waxing to waning. If it is the head of the sun which is depicted in double form (in ariga erua glyphs), then the one at left should be waxing sun and the one at right waning sun - waxing comes first. During the season of growth his face is turned to the right, looking forward, after midsummer sun has turned around and it is reasonable to let his head be depicted as turned around. Alternatively both heads should look en face towards us, and then we can see both eyes:
