[Aztlan] Query: Mesoamerican Scales and Balances?

[Steve Farmer]

Can I ask members of the Aztlan List, re a discussion on a large 
premodern Eurasia research List, if any iconographical evidence -- and 
associated mythology, if any is known -- existed anywhere in 
pre-Columbian Mesoamerica that involved scales or balances?

Scales and balances show up commonly in a wide range of mythological 
and astronomical literature in premodern Eurasia, going back to the mid 
third millennium BCE, and we're trying to trace potentially related 
themes elsewhere.

I've run into some old literature on putative Mesoamerican scales and 
weights, but besides being dated, the literature looks suspiciously 
unreliable. Any help would be greatly appreciated.

Thanks in advance,
Steve Farmer, Ph.D.
