Sadly, this is something that I think we simply do not know. No ancient representation of a Seleucid cataphract survives, and little description is given or their arm or armor. We do know that some of the soldiers in the Seleucid Agema (who fought as heavy cavalry) were Median, raising the possibility that they could have worn Iranian style trousers. Any illustrative reconstruction of a Seleucid cataphract is highly conjectural, mostly based on evidence for Late Antique cataphracts/clibanarii, such as the Dura graffito.
