(Διόδωρος), of SINOPE, an Athenian comic poet of the middle comedy, is mentioned in an inscription (Böckh, i. p. 354), which fixes his date at the archonship of Diotimus (B. C. 354-353), when he exhibited two plays, entitled and Μαινόμενος, Aristomachus being his actor. Suidas (s. v.) quotes Athenaeus as mentioning his in the tenth book of the and Ἐπίκληρος and Πανηγυρισταί in the twelfth book. The actual quotations made in our copies of Athenaeus are from the Αὐλητρίς (x. p. 431c.) and a long passage from the Ἐπίκληρος (vi. pp. 235, e., 239, b., not xii.), but of the Πανηγυρισταί there is no mention in Athenaeus. A play under that title is ascribed to Baton or to PLATO. There is another fragment from Diodorus in Stobaeus. (Serm. 72.1.) In another passage of Stobaeus (Serm. 125.8) the common reading, Διονύσιος, should be retained. (Meineke, Frag. Com. Graec. i. pp. 418, 419, iii. pp. 543-546.)
