3. Son of Clearchus, the tyrant of Heracleia on the Euxine. After the death of his father in B. C. 353, he succeeded to the sovereignty, under the guardianship, at first, of his uncle Satyrus, and held the rule for fifteen years. There is extant a letter addressed to him by Isocrates, in which the rhetorician commends him for his good qualities, gives him some very common-place advice, and recommends to his notice a friend of his, named Autocrator, the bearer of the epistle. (Diod. 16.36; Wess. ad loc. ; Memn. apud Phot. Bibl. 224 ; Isocr. Ep. ad Tim.) [CLEARCHUS.]
