Mykale, a naval battle?

But the costume of the throne bearers aligns much better with the other evidence we have for the costume of the Saka, both in Achaemenid art and from Saka sources. I guess it could just be assumed that the Saka tribute bearers are representative of a Medized population, while the others represent the rest of the Saka.

Yes, this is what I am trying to say. The Saka Tigrakhauda seem to look very different to the rest of the depictions of the Saka. They are also grouped with the contingents from Anatolia and Iran on the Apadana. Are there many surviving Saka depictions of themselves?

This is a very interesting one,which shows a slave boy helping the aristocrat youth drape the chiton. With his left hand he's pulling more matterial up,so it can be belted under the hidden belt.
EDIT: Also note that his chiton is long sleeved,exactly like Alexander's and the Persians' on the Alex. sarcophagus. On the Alex. mosaic,Alexander is the only greek with long sleeves,and Alexander was the first to adopt Persian dress. In the hunt fresco on the Vergina Tomb II Alexander wears a chiton draped like this,but in that case it's sleeveless

I think these are potentually very important. They are almost identical to the tunics worn by the 'Persians' on the Alexander sarcophagus. In my opinion it only backs up my theory that the majority of Greek depictions of Persians show a mix of many different styles, many of which are not Persian at all.

I'm not sure the athenians would be very reluctant to adopt anything that was in fashion,even if it was Persian in origin(and if it was,would they know it?). Persians and Ionians were in constant contact,and if the Ionians adopted something,then why not the Athenians too?

I think they would be reluctant to depict Persian dress in the Parthenon, seeing as it was built on the ruins of the site the Persians destroyed. If it was Persian in origin, I think they would know about it. Even if it was eastern, why would they depict an Athenian wearing anything but Greek clothing on a monument that was promoting the pinnacle of Greek (or Athenian) civilization? We know from Xenophon’s comments on the Ionians that they were not particularly fond of them. Also, are these horsemen not supposed to depict the casualties at Marathon (or is this a myth?).
I think the fact that this is only shown in Greek art speaks volumes.
