Nicostratus, (gr. Nikostratos), an Argive, who, according to Diodorus (xvi. 44 ), was not only possessed of uncommon strength and courage, but was equally distinguished for his prudence and discretion both in the council and in the field. In battle he wore a lion's skin and carried a club in imitation of Heracles. He conducted a body of 3000 Argives to the assistance of the Persian king, Ochus, for his expedition against Egypt; the king having specially requested that the Argives would send him at the head of such troops as they could furnish. Nicostratus seems to have taken a conspicuous part in the military operations of the king. (Diod. xvi. 48.) Plutarch (Apophth. p. 192. a., de Vit. Pud. p. 535) records a saving of his in reply to Archidamus, king of Sparta, who promised him a large sum of money and any Spartan woman whom he might choose as a wife to induce him to deliver up to him a fortress of which he had the command.
