Comic and tragic masks, symbols of the ancient Greek Muses, Thalia and Melpomene. Drama is the specific mode of fiction represented in performance. The term comes from a Greek word meaning "action" (Classical Greek: δρᾶμα, drama), which is derived from "to do" (Classical Greek: δράω, drao). The two masks associated with drama represent the traditional generic division between comedy and tragedy. They are symbols of the ancient Greek Muses, Thalia and Melpomene. Thalia was the Muse of comedy (the laughing face), while Melpomene was the Muse of tragedy (the weeping face). Considered as a genre of poetry in general, the dramatic mode has been contrasted with the epic and the lyrical modes ever since Aristotle's Poetics (c. 335 BCE)—the earliest work of dramatic theory.
