(Πλάτων), one of the chief Athenian comic poets of the Old Comedy, was contemporary with Aristophanes, Phrynichus, Eupolis, and Pherecrates. (Suid. s. v.) He is erroneously placed by Eusebius (Chron.) and Syncellus (p. 247d.) as contemporary with Cratinus, at Ol. 81. 3, B. C. 454 ; whereas, his first exhibition was in Ol. 88, B. C. 427, as we learn from Cyril (ad v. Julian. i. p. 13b.), whose testimony is confirmed by the above statement of Suidas, and by the fact that the comedies of Plato evidently partook somewhat of the character of the Middle Comedy, to which, in fact, some of the grammarians assign him. He is mentioned by Marcellinus (Vit. Thuc. p. xi. Bekker) as contemporary with Thucydides, who died in Ol. 97. 2, B. C. 391; but Plato must have lived a few years longer, as Plutarch quotes from him a passage which evidently refers to the appointment of the demagogue Agyrrhius as general of the army of Lesbos in Ol. 97. 3. (Plut. de Repub. gerend. p. 801b.) The period, therefore, during which Plato flourished was from B. C. 428 to at least B. C. 389.

Of the personal history of Plato nothing more is known, except that Suidas tells a story of his being so poor that he was obliged to write comedies for other persons (s. v. Ἀρκάδας μιμούμενοι). Suidas founds this statement on a passage of the of Plato, in which the poet alludes to his labouring for others : but the story of his poverty is plainly nothing more than an arbitrary conjecture, made to explain the passage, the true meaning of which, no doubt, is that Plato, like Aristophanes, exhibited some of his plays in the names of other persons, but was naturally anxious to claim the merit of them for himself when they had succeeded, and that he did so in the Parabasis of the Peisander, as Aristophanes does in the Parabasis of the (See the full discussion of this subject uiider PHILONIDES.) The form in which the article Ἀρκάδας μιμούμενος is given by Arsenius (Violet. ed. Walz, p. 76), completely confirms this interpretation.

Plato ranked among the very best poets of the Old Comedy. From the expressions of the grammarians, and from the large number of fragments which are preserved, it is evident that his plays were only second in popularity to those of Aristophanes. Suidas and other grammarians speak of him as λαμπρὸς τὸν χαρακτῆρα. Purity of language, refined sharpness of wit, and a combination of the vigour of the Old Comedy with the greater elegance of the Middle and the New, were his chief characteristics. Though many of his plays had no political reference at all, yet it is evident that he kept up to the spirit of the Old Comedy in his attacks on the corruptions and corrupt persons of his age; for he is charged by Dio Chrysostom with vituperation (Orat. xxxiii. p. 4, Reiske), a curious charge truly to bring against a professed satirist ! Among the chief objects of his attacks were the demagogues Cleon, Hyperbolus, Cleophon, and Agyrrhius, the dithyrambic poet Cinesias, the general Leagrus, and the orators Cephalus and Archinus; for, like Aristophanes, he esteemed the art of rhetoric one of the worst sources of mischief to the commonwealth.

The mutual attacks of Plato and Aristophanes must be taken as a proof of the real respect which they felt for each other's talents. As an example of one of these attacks, Plato, like Eupolis, east great ridicule upon Aristophanel's colossal image of Peace. (Schol. Plat. p. 331, Bekker.)
