The Atlantean civilization frrom 2500 BC through 1159 BC scoured the earth for trade opportunity and by default became the reservoir and distributor of both older traditions and new discoveries.
Knowing this it is clear that all remaining traditions held by a local living tradition needs to be carefully picked over as we are now doing with the Kolbrin Bible which most certainly is the remains of a Bronze Age library that predated the Hebrew Bible but part of the same tradition.
The studied ignorance of intellectuals can be safely ignored. In the case at hand this repository held correct knowledge of Sirius that could only be acquired using vision enhancement. Not an unreasonable proposition considering the secrecy of scholarship then.
