These 'fingers' look like henua. We can also see the very long henua in the demarcation 'snake' between the different months on the sun door, evidently of the same nature as the 'socle' lines. Yes, everywhere also in the form of the 'Staircase Sign'. Sun climbing step by step up the steep - ste(e)p - inclinations of the Andes.

The path of the sun, we could say. That is the origin of the henua glyph. And possibly it all began with GD24, after which straight cut marks across were invented to illustrate that measurements had been done.

These cut marks are like the marks on wooden staffs (limbs of trees). And the rays of the sun may be seen as 'fingers', most clearly so sometimes at dawn when his rays can be likened to rosy tentacles.

Such 'fingers' are straight as arrows, which - I believe- explains why arrows are used in solar myths, e.g. when Odysseus shoots through all 12 axe-heads. But a spear is also a good image, as when he blinds Polyfemos. Spears are straight and made of wood, trunks of trees.
