renowned Athenian general and admiral who flourished about 390 B.C. (See Attica.) After his defeat by Lysander, he fled to Evagoras, king of Cyprus, and then put himself under the protection of Artaxerxes, king of Persia, with whose army he delivered Athens from the Lacedemonian yoke and restored the walls. He afterwards (B.C. 394) defeated the Lacedemonians in a naval encounter near Cnidos, and thus deprived them of the empire of the sea (which they had held ever since the taking of Athens), besides crippling their resources in other respects. According to one account, he is said to have been put to death by Teribazus, when on an embassy to the Persian court; but it seems more probable that he escaped to Cyprus, where he had considerable property, and that he died there a natural death B.C. 388.

Conon, of Samos, a mathematician and astronomer, who flourished during the reigns of Ptolemy Philadelphus and Euergetes. He was the inventor of the curve called afterwards from its more famous expounder the spiral of Archimedes, and is mentioned in terms of admiration by the Syracusan mathematicians. None of his treatises are extant. There is also a grammarian of the same name who flourished in the age of Augustus, and wrote a work on the mythical period of the early colonies.
