According to Wikipedia [en.wikipedia.org] Khufu’s full name was Khnum Khufu, which broadly translates as “Khnum protects me”. Khnum of Wiki and Knemu of Budge are the same deity. This makes me wonder if we should be connecting the QEBH form of Khnum to Lord of Sakhbu to the conjunction of the sun and the moon. Ie we are looking for a new moon on the 15th day of Peret. Back to Stellarium to investigate.
I have been looking at the astronomic data and I think I know what is going on. If you want to investigate using Stellarium, you must compute 15th day of Peret to each particular epoch - year. The value I posted from Wikipedia is from 2500 BC. If you want to go to Khufu's time this needs modifying. Also, in the other speed of light thread I posted how from the Westcar Papyrus we can compute the distance between the Earth and Saturn. They encoded this for a reason. We need to use Stellarium to check the Saturn distance. I don't think the event or events of interest took place during a new moon. But I do think that there were particular circumstances involving the Moon. The other clue to what is encoded is the Giza layout.
