At vaha mea in this glyph dictionary a reversal from 'black' to 'red' (at Ab4-68--69) was suggested, a judgment based primarily on the form of these two hoea glyphs in comparison with other similar ones in Tahua:

Ab4-63 Ab4-64 Ab4-65 Ab4-66 Ab4-67
Ab4-68 Ab4-69 Ab4-70 Ab4-71 Ab4-72

To reinforce the argument numbers were used:

 
... Counting glyphs from the specially designed vaha mea (in Aa6-67) to the exceptional hoea (in Ab4-69) we find a powerful numerical signal:
 
499
Aa6-67 Ab4-69
0 500
 
500 may seem to be a coincidence (although for me it suggests a hundredfold rima - 'fire, fire') ...
 
In the rongorongo system of measuring glyph distances, it is not always the normal counting that counts. 500 is just to draw our attention, and the main signal to observe is 314 (100 * π), i.e. the fact that Ab4-69 is the next to 314th glyph on side b. Half a cycle is completed at Ab4-69 (because the whole cycle is computed by using 2π, or 628).
 
Aa6-67 and Ab4-69 serve as markers defining half a cycle. Therefore both of the glyphs are aberrant from the norm (in order to catch attention) ...
 
 
... Together with the following mea we are very close to vaha mea, as if there was a word play (haha mea) together with a glyph play
 

Aa6-67

Ab4-68--69

vaha mea

haha - mea

In Aa6-67 the (sun) fish is designed as if being swallowed by a hoea glyph. At summer solstice the opposite of mea occurs - the dark season will begin.

Ab4-68--69, half a cycle later, has mea at right ...

 

4 * 70 = 280 at Ab4-70 could mean 140 days. The 'ghostly' (cfr the 'broken' neck line) manu kake is very close to loosing his two heads:

Ab4-68

Ab4-69

Ab4-70 (314)

 Ab4-71 Ab4-72

By force of their 'broken' necks and, secondarily, by being close together we can now see the two manu kake as a pair:

27
Ab4-43 Ab4-71

28

30 glyphs before ua in Ab4-70 another identical ua is located. Together they suggest rain is coming, and we remember the 'Beast' (Aa6-66). Furthermore, we get a clue to what the special henua-sign at right in period 6 could mean:

6 22  
Ab4-40 Ab4-47 Ab4-70 Aa6-66

30

It could be added that 6-66 probably is here to be interpreted as 6 + 6 + 6 = 18, because 180 days from winter solstice midsummer is reached. And the assymmetry in the two ua glyphs are repeated in the vomit of the Beast. Presumably there are two similarly formed entities in ua, maybe a sign of conjunction.
