2. The stars of Ophiuchus should be listed:

We need to go back to the 17th hour for the beginning of the constellation - notably not at Ras Alhague but earlier. Instead we find Yed Prior (δ) and Yed Posterior (ε), a pair of stars not far below the 0º declination line:

"The traditional name Yed is derived from Arabic meaning 'the hand', and the two stars are the left hand of Ophiuchus (the Serpent Bearer) that holds the head of the serpent, Serpens Caput." (Wikipedia) I imagine this 'hand' could correspond to the Mayan Chikin hand at the horizon in the west or to the right hand of Blood Moon receiving the 'saliva' from the 'Old Bone' up it the 'Tree'.

I have above listed 12 stars for Ophiuchus (rising heliacally in the 17th hour). 9 of them are south of the equator and 3 above.

"Marfic, or Marfik, is from the similar Arabic Al Marfiķ, the Elbow, which it marks.

Bayer, Burritt, and probably others have it Marsic, doubtless from confounding the antique forms of the letters f and s.

This same title appears for κ Herculis." (Allen)

I have changed my Marfik at tamaiti in Ga7-11 to Marfik Herculis. The probably important cardinal glyph Ga7-17 exhibits a pair of elbows. Allen again:

"υ, a 4½-magnitude, was She Low, a Market Tower ..."

"ζ, 2.8, near the left knee, was the Chinese Han, an old feudal state."
