He led the royal forces in Mesopotamia against the rebel Molon, served as the governor of cis-Tauric Asia Minor from 213 BC onwards, and was a general at the Battle of Magnesia.
Zeuxis, son of Kynagos, was engaged in 221 BC in the war with Molon, satrap of Media, whom he prevented from crossing the Tigris.
