(Ζεῦξις), a general in the service of Antiochus the Great. He was engaged in the war with Molo, whom he prevented from crossing the Tigris. Being placed under the command of Xenoetas, he was left by the latter in charge of the camp, when he made his ill-fated attempt to overpower Molo. But he retired on the approach of Molo, and suffered the latter to cross the river without opposition. When Antiochus himself marched against Molo, Zeuxis persuaded hint to cross the river, and was in command of the left wing in the battle that ensued. He also took a prominent part in the siege of Seleucia. (Plb. 5.45_60.) It is perhaps this same Zeuxis whom we find satrap of Lydia under Antiochus the Great. (Plb. 21.13.) To him Philippus, when at war with Attalus, applied for a supply of corn, which he obtained. (Plb. 16.1, 24.) In the decisive battle with the Romans, Zeuxis was one of the commanders of the front line (Appian, Syr. 33), and after the defeat of Antiochus was one of the ambassadors sent to the Scipios to treat for peace, on which mission he proceeded to Rome. (Plb. 21.13, 14, 22.7; Liv. 37.41, 45.)
