Ancient Greek comedy takes interesting approaches to mythological narrative. This article analyzes one excerpt and eight fragments of ancient Greek Old, Middle, and New Comedy. It attempts to show a comic rationalizing approach to mythology. Poets analyzed include Aristophanes, Cratinus, Anaxilas, Timocles, Antiphanes, Anaxandrides, Philemon, Athenion, and Comic Papyrus. Comparisons are made to known rationalizing approaches as found in the mythographers Palaephatus and Heraclitus the Paradoxographer.
