Yes, i did come across the Sumerians using the term 'Zib-Ba-An-Na' as 'balance of Heaven' for Libra around 2000 Bc,


Libra has been mentioned in several cultures. The Summerians identified Libra as Zib-Ba-An-Na, or "the balance of heaven" in 2000 B.C. The idea of balance is most likely because the sun was in Libra during the autumnal equinox during those times.

The suggestion there is as i pointed out due to it's relationship at the time to the Equinox. There are plenty of populist websites directly comparing the Scales of Ma'at to Libra, but i can't find any academic source that considers this.


Surprisingly really, as the scales of Ma'at occupied a cebtral position in the Duat, in temporal terms and relative positioning, and Libra at this period in the skies certainly satisfies all criteria of centrality and harmonious balance.
