(Ἀρίσταρχος).
1. Is named with Peisander, Phrynichus, and Antiphon, as a principal leader of the "Four Hundred" (B. C. 411) at Athens, and is specified as one of the strongest anti-democratic partisans. (Thuc. 8.90.) On the first breaking out of the counter-revolution we find him leaving the council-room with Theramenes, and acting at Peiraeeus at the head of the young oligarchical cavalry (ib. 92); and on the downfall of his party, he took advantage of his office as strategus, and rode off with a party of the most barbarous of the foreign archers to the border fort of Oenoe, then besieged by the Boeotians and Corinthians. In concert with them, and under cover of his command, he deluded the garrison, by a statement of terms concluded with Sparta, into surrender, and thus gained the place for the enemy. (Ib. 98.) He afterwards, it appears, came into the hands of the Athenians, and was with Alexicles brought to trial and punished with death, not later than 406. (Xen. Hell. 1.7.28; Lycurg. c. Leocr. p. 164; Thirlwall, iv. pp. 67 and 73.)
