We are here not going to use any other kava sign than the two mentioned (in Aa8-31 respectively Ka3-11). The investigation will be complex enough anyhow (though important for the further developments).

The first step of the investigation is to integrate Aa8-31 in the viri structure. There are 1334 glyphs in Tahua. The text can be used as a calendar with viri glyphs marking the main divisions (in multiples of 29 glyphs). With a slight improvement of what has been presented earlier (at viri in this dictionary) the overall 'map of the structure can be regarded as:

58			520		752
	Aa8-85	Ab1-1		Ab7-26		Aa8-26
2 * 29	522 = 18 * 29			754 = 26 * 29

The beginning of the text is at Ab1-1 and the end at Aa8-85. With an even number of glyphs there are two central glyphs, not one.

1334 = (18 + 26 + 2) * 29.  The 4th viri (Aa5-7) is not needed for our present 'map' of the Tahua text, yet it is informative to include it when viewing the development:

Ab1-1	Ab7-26	Aa5-7	Aa8-26
Ab1-1 is harmoniously drawn, but short in contrast to Ab7-26. Aa8-26 has a thick bottom 'tail' end, whereas Ab7-26 contrariwise has a thick upper 'tail'. Aa5-7 and Aa8-26 are drawn as if deformed. Neither the top part nor the bottom part in Aa5-7 is thick, and the glyph is slightly stooping forward, as if it was old. The top end in Aa8-26 looks as if it has been cut off.
