The two relationships - 1) Vega/Canopus and 2) Sirius/Canopus - are the same across both civilizations. Carried through by myth and sacred geometry.
#1 gives us Year 1 of the Great Year, and #2 gives us the time of the Golden Age and later, the death of the King. A cross might have Christian connotations to some. But originally, it symbolised the time of The Beginning.
We are getting close to a reasonably accurate measure of that date.
Tulip talks of 40 turns of The Wheel in a million years. Probably, if each turn has the same period. But it's at just which turn did the knowledge become apparent.
Below are the Sumer King Lists. As you can see, some Kings had very long reigns. Most probably, these kings are the ruling Pole Stars of the time. The interesting thing is that this measurement goes back about ten turns of The Wheel. So, somebody must have been around observing and measuring. After that many turns, the pattern would have been established and aberrations much more noticeable. The prophecy side of astronomy would have been well founded.
