5. Let's turn our eyes in another direction. The uplifted right arm of Orion the Warrior is inside the Milky Way, this we can see in a picture by Bode:

Most of the stars in the arm are in the 7th hour:

We need to update our list with these stars. Moving from top down there is first the pair χ¹ and χ², then ξ and ν, and finally μ. But I will as usual order by right ascension:

χ¹ Orionis 05h 54m 23.08s 05h 54.385m 497.1

ν and ξ Orionis    

I have not been able to find any useful individual name for any of these 5 stars. But in Allen we can read that ν and ξ were the Chinese Shwuy Foo, a Water-depot. Furthermore:

"They mark Orion's right hand, ξ being the radiant point of the fine meteor stream, the Orionids, of the 18th of October."

The idea of a crumbling right hand (5) could perhaps be of use when trying to understand Ga1-27--28.

And the top part of the henua signs could mean 'water'. In Ga1-29 the idea of water seems to be illustrated in the right arm of the headless figure (tagata rima aueue).
