Today, we went here:
This is Monte Albán, the site of the Zapotec civilization from 500 BCE to 800 AD. Our professor came here in his twenties to help with later excavations, and had a hand in most of the things and signs that are in the accompanying museum, which is pretty awesome.

In the photo above you can see several temples, but by the last era, 10,000 to 20,000 people inhabited Monte Albán.
On this slab is Zapotec writing. I can tell you that the two bars and the dot at the very bottom mean the number 11 (bars = 5 and dots = 1).
