(Καλλιάδης), a comic poet, who is mentioned by Athenaeus (xiii. p. 577), but about whom nothing further is known, than that a comedy entitled was ascribed by some to Diphilus and by others to Calliades. (Athen. 9.401.) From the former passage of Athenaeus it must be inferred, that Calliades was a contemporary of the archon Eucleides, B. C. 403, and that accordingly he belonged to the old Attic comedy, whereas the fact of the Agnoea being disputed between him and Diphilus shews that he was a contemporary of the latter, and accordingly was a poet of the new Attic comedy. For this reason Meineke (Hist. Crit. Com. Gr. p. 450) is inclined to believe that the name Calliades in Athenaeus is a mistake for Callias.
