Ca3-21	Ca3-22	Ca3-23	Ca3-24	Ca3-25

In the koti chapter this Rogo glyph was found to be probably referring to winter solstice.

Later, at maro, it was 'proven' that the 'nut' in Ca1-26 - probably the 'head' of the previous 'Sun King' - was connected to manu kake in Ca14-26 (because 14 * 26 = 364):

However, as usual nothing in the rongorongo texts is simple, and 314 was also found to be the ordinal number for Rogo (in Ca3-25), given that we begin to count from Cb5-17 - the glyph immediately following another Rogo (this one with a high stature and with his body depicted as caught in a net or something similar):

side b			side a
109		238	75				314
	Cb5-16			Ca3-25 (76)	Ca4-1	Ca4-2
	0			314	315	316

There are 392 + 348 = 740 glyphs on the Mamari tablet. Possibly 28 has been used as a measure on side a because 14 * 28 = 392. On side b we can count 12 * 29 = 348.

392 = 78 + 314. We know the value of π, but what is 78? Considering the nature of Ca4-2 its ordinal number can possibly be explained as 6 * 13 = 78. Moreover, 42 (as in 4-2) when added to 36 equals 78. But 78 is also = 26 (cfr Ca1-36) + 52 (= 2 * 26). Ca4-2 has a key role to play.
