(Ἡγησιάναξ), one of the envoys of Antiochus the Great, in B. C. 196, to the ten Roman commissioners, whom the senate had sent to settle the affairs of Greece after the conquest of Philip V. by Flamininus (Plb. 18.30, 33; comp. Liv. 33.38, 39; App. Syr. 2, 3.) In B. C. 193 he was sent by Antiochus as one of his ambassadors to Rome; the negotiation, however, came to nothing, as the Romans required that Antiochus should withdraw his forces from all places in Europe,--a demand to which Hegesianax and his colleagues could not assent. (Liv. 34.57_59; Appian, App. Syr. 6.)
