That's most likely referring to the reliefs from the stoa of the temple of Athena Nikephoros from Pergamon, which have been dated to around 180 BC.

also, a visit to Polybios is in order.
Polybius refers to troops armed "in the Roman manner" wearing mail. There is no mention of phalangites wearing mail in Polybius.
