Rauru is not a Moon son, but a Venus son, yet the position is similar. In the Mayan calendar the Venus Turtle of Kayab obviously signifies 'the biting of Sun' (Chikin, Manik-Kin) at the horizon in the west, as if to comment upon why the drums were sounding (rutu) already at the 16th month Pax. The woman drummer has only 1 visible limb, a left leg, but maybe it is not her own leg but the missing leg of Sun (360 - 300 = 60):


16 Pax	17 Kayab	18 Cumhu
60 days

19 Vayeb (365)

The Bay of Turtles, Hanga Hoonu, could be a name for a 17th month. The number of the 18th son of Tu was 17 and his name Rauru we now can immediately understand as Ra-uru, i.e. Sun is here only an image, no longer present in person. Like the injured Kuukuu he has drawn back into a cave with his broken spine. Outside the cave are standing 6 images of stone, maybe each one with a value of 10 days.

Earlier and at the end of the 14th son, Maroro, the number is 280 and in the Mayan calendar this is Kankin:


1 Pop	2 Uo	3 Zip	*4 Zotz*	5 Tzek (100)


6 Xul	7 Yaxkin	8 Mol (160)	9 Ch'en	10 Yax (200)

11 Sac	12 Ceh	*13 Mac (260)*	*14 Kankin*	15 Moan (300)

The rain clouds - cfr the 6 'droplets' hanging above for 80 days beyond summer solstice - have gone away with Mac. Sun is once again shining and everything is drying up (he maro). But only for a short while before he will go down in the west. Mac ends with day number 260 which is like a 'compromise' between Mol and Cumhu:

8	*Mol*	*160 = 60 + 100*
13	*Mac*	*260 = 60 + 200*
18	*Cumhu*	*360 = 60 + 300*


1 Pop	2 Uo	3 Zip
60 days

It is similar to how 364 is like a compromise between 280 and 392, which should make us rethink. Maybe day number 364 (like day number 260) once was regarded as the time of autumn equinox.
