 Plutarch tells us of Mithridates VI of Pontus, "The Great", having a corps of 'Chalkaspides' against Sulla at Chaeroneia.The majority of the Seleucid phalanx was probably formed by the two corps that are mentioned in the Daphne Parade of 166 BC, namely the 10,000 "Chrysaspides" and the 5,000 "Chalkaspides".Little else is known specifically about them, although they may have been present at the battle of Beth-Zachariah in 162.
