CLEARCHUS, a tyrant of Heraclea in Pontus,
who was killed by Chion and Leonidas, Plato's pup-
ils, during the celebration of the festivals of Bacchus.
He had enjoyed the sovereign power during 12 years.
A Lacedæmonian sent to quiet the Byzantines. He
was recalled, but refused to obey, and fled to Cyrus
the younger, who made him captain of 13,000 Greek
soldiers. He obtained a victory over Artaxerxes, who
was so enraged at the defeat, that when Clearchus fell
into his hands by the treachery of Tissaphernes, he put
him immediately to death.
