1. The 12th hour is 6 months beyond equinox and its beginning is where Alkes (α Crateris) is rising heliacally:

On the opposite side of the deep curve of Hydra is Corvus in the 13th hour.

My imagination runs away with me and whispers in my ear: This must be Hanga Te Pau.

Hanga Te Pau
Gb5-12 (366)
January 1
Unforgotten are they, these three. kai viri kai viri.ko raua ana a totoru. p. 17
And therefore this is the (right) land lying there; peira tokoa te kainga e moe mai era
this is Te Pito O Te Kainga, which also received its name from the dream soul. ko te pito o te kainga i nape ai e toona kuhane.
The canoe continued its exploration and in a sweep sailed on to Hanga Te Pau. hokoou.he rarama he oho te vaka he vari ki hanga.te pau
They went ashore and took he tomo ki uta.he too
the food with them. i te kai ki uta. p. 18
They pulled the canoe onto the beach and left it there. hee totoi i te vaka ki uta he hakarere.
Ira sat down with all the other (companions) he noho a ira anake.

6 months beyond spring equinox north of the equator is where Easter Island will receive spring, where 'land' in the sky will arrive. Haga means a bay and thus a place suitable for a canoe to make 'landfall'.

I suddenly realize a solution to a problem which has been bothering me for a long time, viz. why the glyph type moe evidently is located at the beginning of seasons, e.g. in Ga1-20, instead of at the end (where we should find sleepy persons) - see at Moe:

Ga1-17 Ga1-18 Ga1-19 (492) Ga1-20 Ga1-21
Elnath (489.9)  Mintaka (491.4)   Alnilam (492.7)  Alnitak, Phakt (Phaet), (493.7)
  'Pyramid of Menkaure'   'Pyramid of Khafre' 'Pyramid of Khufu'
The Hem

The Twin Pyramids

The reason could be a wish to describe how the 'land' is lying there dormant in front, spread out and waiting: te kainga e moe mai era.
