Thanks for the link - it is certainly an interesting read. I wasn't setting out to prove or disprove Pi was known when I read this story in the Westcar Papyrus. Essentially, I theorise the entire set of stories in the Westcar Papyrus are mythological. They leverage a mix of real characters (e.g. Sneferu, Djoser and Khufu) and fictional characters (Djedi) intermingled with various wonders / fantastic things . There is a little background on my thinking in my post here: [grahamhancock.com]
Lyne Kelly in her work demonstrates the encoding of various information into story, song and dance. You can get a taste of her expertise from her website here:
Also her other book here:
My interpretation of this story is actually the scene is that the story is representative of a constellation and the circular motion is deliberately depicting a scene from the night sky. Lull and Belmonte identify a boat constellation known to the Ancient Egyptians to Sagitarius in Table 6.1 on p162. Also in discussion on pp 182-183:
Lull and Belmonte
Surprisingly, or perhaps not, all these can be easily identified in the Zodiac of Dendara with a fish at the bottom of the water-pouring Hapi, an inundated field in the middle of Pisces, a bird and snake close to Leo and a small bark (much larger in other representations; ... a special mention should be made in the case of the Bark. We have shown that the ancient Egyptians perhaps recogized a boat or bark (wi3) in the area of Sagittarius.
The fact that there were 22 people on the boat gave me reason to pause and think about whether this papyrus connects Pi to astronomy?
