Some cool things I found in pdfs about trying to decipher the ancient Zapotec glyphs.
In red are possible clubs / spears with one side coated with obsidian (which makes me believe that nothing would prevent a club with both sides)
The central figures are apparently noble warriors or warrior priests using for the exfoliated of their victims, in their hands a small shield and perhaps an atlatl ??
In this second image we see in the center what is probably a royal couple worshiping an ancestor. underneath well-armed warriors with padded cotton armor, many wearing pastas with cotton covers.
