The 'old woman' (nuahine) who 'lights a fire' () in her 'oven' (umu) is sitting at full moon, personifying the moon:

"[Englert 1948, 165:] '... se selia nombrar Ko te Nuahine káumu ŕ rangi kote kote que significa: La vieja que enciende el curanto en el cielo kotekote. Puedo haber sido una personificación de la luna porque las viejos decían, comentando este nombre, que no es una montańa que seve en la luna, sino una mujer anciana que está suntada [sentada?] al lado un gran curanto umu pae (de piedras en circulo)." (Barthel)

The divided (kotikoti) sky (ragi) means the point where one season is finished and another is beginning. We can compare with the kuhane station Hatinga Te Kohe (the broken 'bamboo' staff) at the end of the solar year (12 * 29.5 = 354), as illustrated in Ab1-37

A new season must begin where the old one ends, therefore hanau (birth) is the main sign in the middle between 'death' (ihe tau) and 'birth' (reversed ihe tau).

While reading Tahua Metoro probably saw the old woman who 'lights a new fire' at noon,

Aa1-24 Aa1-25 Aa1-26 Aa1-27
ko te nuahine -  i mamau i te ahi e uhi tapamea ko te ahi - hakaturou ki te henua

The glyph number is 1-24, which can be read as 'growing sun (1) has reached his end (24)'. In Ca7-24 this mode of language says 'growing moon (2) has reached her end (24)'.

In Aa1-24 the 'old woman' is standing tall, but the eating gesture is there. To eat (kai) has a secondary meaning of becoming pregnant - which everybody will notice when the lady is growing thicker. Metoro explained: i mamau i te ahi - she holds (ma'u) the 'fire' (ahi). The new fire is the day of tomorrow (which will be born at midnight).

At right (future) in the glyph a kind of 'navel string' connects to the middle of a picture of a sun (the sun of tomorrow). It comes from the elbow of the old woman. The joints are symbols of flexibility, movement, and change. Genesis has ultimately the same root as knee.
