3rd century BC Greek Alphabet forms

[Ancyrean]

Nice work TA!

I wonder how they weren't confused with similar looking letters (like the Syrakusan and Cretan Gamma looks like the mainstream Lamda, or one version of Corinthian Epsilon looks like the mainstream Beta, or Epiriote Iota looks like mainstream sigma etc). I'm sure each polis had scribes with the knowledge of such differences, but for the average citizen were these different versions in the final analysis deducable from the context?

Speaking of Ancient Greek, may I also ask about one detail in EB that I was wondering about? Most Hellenic/Hellenistic units carry a banner in battle with an inscription on it that (I guess) reads as "Pezoi". I can make out it's a plural form, probably of "Pezos", but what exactly does that word mean?
