Reconstructed Persian weapons

[hoplite14gr]

Ardeshir, I like the fact that you are among the few people who bothered to check combat mechanics.
Greeks seem to get the better of "immortals" or satrapal elite troops due the weight and mass of their shields.
Being armored is not enough in phalanx fight and Giannis is right when he says that the phalanx evolved against itself.

But Aisxylos talks of the alsos (grove) of Marathon. In the grove that phalanx could not be formed and the Athenian logada who were sent to clear it suffered heavy casualties from the Persians.

Based on Plutarch, Pausanias and Photius Epitome I agree that you are right when you say that "immortals" were probably comited the second day. These authors use Ktesias as a source and Ktesias was a doctor in the Persian court and probably better informed.

I find your idea on the helmets rational but Sassanid and later Islamic art shows clearly the covered helmet.
But helmets under the tiara for the Achaemenides? Is there any excavated evidence in Iranian site from so small helmets?
There is only one helmet that might fit this idea. It belonged to the Axel Gutman collection and it is being described as "Middle Eastern"

Kind regards
