Use of the hoplon into the Roman period?

[hoplite14gr]

Hi Stefanos. Do you know of any other occurences of the word hoplon to describe shields?

Diodorus 17.21.2 is the most well known, yet the discription to a native speaker is not that Diodoros uses the term HOPLON for the shield but as a term to give a description of the equipment because he thought it better to express himself in this way.
Diodorus talks about Alexander in Granikos. Alexander was mounted.
If he had a shield it would be Thacian or a small Beotian. Diodorus does not specify which hand he talks about. As I understand he means the exposed hand that held lance or sword. They are both OPLA_=weapons.
So we cannot be sure that he talks about shield here.

I will try though SOUDA and HYSICHIOS lexikons that they are used as basis.
But I doubt that anything will come up
Kind regards
