(Σώπολις), son of Hermodorus, commanded the Amphipolitan cavalry in the army of Alexander the Great, in the battle against the Triballians on the banks of the river Lyginus, B. C. 335. He is mentioned again as commanding a troop of horse, probably the contingent from Amphipolis, at the battle of Arbela in B. C. 331; and we may perhaps identify him with the father of Hermolaus, the youthful conspirator against Alexander's life [HERMOLAUS]. (Arr. Anab. 1.2, 3.11, 4.13; Curt. 8.7.)
