Need some information about Mantinea 207 BCE

[hoplite14gr]

Still digging for Pausanias. Hope it will solve the problem.
Well petrovolos means shooting (hurling?) stones. Voli in Greek is shot.
Oros (mountain) is from 800 meters anything less is lofos (hill)
At least our school geography said so.

So Polyenos talks about a mountain at least 800m (2400 feet or more).
Thessaly is a flatland surrounded by mountains. Olympus (N) Pindos (W) Ossa (NE) Pelio (E). Only small hills exist north of Pagassai (modern Volos) where Phokians lost their final battle.

So either Polyenos makes mistake (or the medieval copier) and we have increased liklehood of artillery if it happened at the Paggasai hills or the event happened at Tempi (north pass between Olynpus and Ossa) and Duncan's scenario is very possible.

Kind regards
