Trianon - decoding its hidden astrology
Trianon,possibly from ATRIA ANAN.
ATRIA is the star Atria, opposite Bellatrix. Currently at 21 Sagittarius. This is debatable, as TRI could mean 3.
ANAN is the equivalent of Scorpio (and we will use Scorpio 3 for this).
When was star Atria conjunct Scorpio 3?
From Scorpio 3 to Sagittarius 3 = 30 degrees
From Sagittarius 3 to 21 = 18 degrees.
30 + 18 = 48 degrees of precession ago.
x 71.6 (you can always round it up to 72, although your calculation will be a bit off, we will round it up anyway).
Around 3,400 years ago.
