Hello @Dasaavawar About the Heroes it was very difficult to find them are real names of Zapotec rulers of Monte Alban in the pre-Classic and Early Classic period(Take a look at the reference links I quoted above.). Their names are attested (names date as was common at that time) but as we do not yet have a complete translation of the Zapotec writing system, we therefore do not have access to their recorded heroic deeds. Miltla was not a big city even in 500 BC. -1.a.c (period of 0ad) Nor in period 1 d.c. to 500 d.c. (period that I believe Delenda Est accesses in a way too). Mitla only became the city we see after the fall of Monte Alban.
About the siege ram and the canoe are themes that have been and can still be debated.We have two facts
1# The Mesoamericans already knew about the wheel, but we don't have access to any information about a use in a siege ram. But that doesn't change the fact that a ram for gameplay effects becomes necessary in 0ad.
2# Canoes were known throughout America but we have to remember the Zapotecs even in the Mesoamerican context was not a civilization marked by the domination of the sea, in fact they were much more a mountain people and high altitude valleys than anything else.
Sorry, my google translater english.
