7. In the Babylonian zodiac, at least as it has been reconstructed for us, the bottom of the Milky Way band is designed as the letter V:

At Eridu flows of water are visiualized and on the other side of the V, at Ninmah, a child is exhibited. Raven comes later, looking down at the Abyss.

Perhaps this V is a 'memory' of where ca 26,000 / 4 = 6,500 years ago the U-turn of Hydra's tail was. In the picture above there is no sign of U in the taíl of the Serpent, but a memory of the thirsty Raven not capable of reaching to the water on the other side of U (or V) could explain why there is a watery Abyss below - and out of reach of - Raven.

"During the late Middle Ages, two forms of 'v' developed, which were both used for its ancestor 'u' and modern 'v'. The pointed form 'v' was written at the beginning of a word, while a rounded form 'u' was used in the middle or end, regardless of sound." (Wikipedia)

Corvus and Crater were easily moved by the precession, because these constellations were well defined. At the beginning they could have announced where the rainy spring changed to a dry high summer, first a bowl of water and then a thirsty bird, later clouds of rain could explain why there was a change from a gradually lighter sky to a beginning dusk.

A Milky Way zodiac would have been longer than the cycle of the solar year, so much we can immediately see. In the G text there are 472 - 365 = 107 glyphs more, which might indicate this difference. This number happens to coincide with the distance to π Cancri:

71 * (139.2 - 107) = 2286, which implies 107 could have been an important part of a cosmic structure created ca 400 B.C.

From Ka4-13 to the end of the text there are 107 glyphs. Does it mean extra nights began with π Cancri? 74 + 107 = 181 and maybe there is no place for Leo on the K tablet. The first star of Leo was Al Minhar al Asad in Gregorian day 222:

Beyond the apex of the year, where the King's head seems to be used as an egg for the next year, there is an empty stretch, possibly 107 days long, where nothing can be seen - maybe because the King's head has been buried:
