The Mayan signs work like catalysts, pushing my thoughts about rongorongo forward. The all important quincunx pattern cannot be shown in rongorongo texts, because the 5 'pillars' are inside the perimeter and the rongorongo system of glyphs require (in principle) all signs to be outside with nothing inside.

Number 5, it occurs to me, can alternatively be shown by the 'bar', as for instance in the numbers 8, 12, and 16 in these ch'en glyphs:

Probably the three dots of the foundation also are numbers.

In the rongorongo system a 'dot' could be a 'feather mark' and a 'bar' could be the henua glyph type. In for instance G there are 32 period-ending glyphs with the henua sign. 32 * 5 = 160 = 10 * 16, possibly indicating the season of the sun.

Let us continue with stations 7-9 of the Rain God:

"The fourth locality [i.e. the 7th] is simply the normal 'sky' glyph with an unusual prefix.

The head of the rain god is the fifth locality. Perhaps the accompanying glyphs should be regarded as a deity name rather than a locality, but the glyger is found only in this context and, surprisingly, has the 'in' prefix.

The sixth locality is the place of crossed bones, interpreted by Barthel as a cist; it is interesting to find it represented by the little figure without a normal head (T227, probably the same as T703), which frequently appears in astronomical contexts. T227 also appears with the head of the muan bird as the glyph for the muan bird's head, as a place." (Kelley)

If we still are in the sky region (which the 7th locality seems to tell us), then the 9th location is the time of Muan, the head of the sun is no longer with us:

The head is buried separately, the 8th location seems to indicate that. The prefix 'in' of course means that sun is 'in' = 'inside', not visible any more.

We learn that the 'crossed bars' means simply 'sky'. I have deduced it means absence of the rays from the sky, as for instance in Uo and Zip:

1 Pop	2 Uo	3 Zip	4 Zotz

The dotted line around the sun eye iris also shows the absence of the sun, I believe:

The locations 7-9 should therefore correspond to months 13-15:

13 Mac	14 Kankin	15 Moan
