What I find interesting is the association between Khufu and Saturn. In Hellenic the isopsephy value of Cronus(Saturn for the Hellenes) is equal to that of Ptah as Phtha.
PhThA = 500 + 9 + 1 = 510 = KRONOS = 20+100+70+50+70+200
If Hapi relates to Aquarius then he is next to the 'Boat'. I think it might be as stretch to consider that 'flock' referring to sheep, although there does seem to be a AE 'Sheep' constellation below the boat.
Based on my decodings, the stories seem to encode a vital piece of information:
The birth date of Khafre
There are celestial alignments taking place but we also have celestial pre-cursers that take place on other dates. The scope of these stories was to help us pinpoint using astronomy these dates. They might have succeeded, unfortunately parts are lost so some corroborating evidence cannot be found.
