Another novelty is his use of the prologue. Since this is properly nothing but “that part of the play which precedes the first song of the whole chorus,”[45] prologues are of course found in Æschylus and Sophocles. The peculiarity of the Euripidean prologue is that it tends to be non-dramatic, a narrative enabling the spectator to understand at what point in a legend the action is to begin. It is from Euripides’ use of the prologue that the modern meaning of the word is derived. Aristophanes in his _Frogs_ makes a famous attack upon most[46] sides of Euripides’ art as contrasted with that of Æschylus. But it is often forgotten that, damned utterly as the younger tragedian is, Æschylus by no means escapes criticism. Many of the censures put into Euripides’ mouth are just and important; it seems likely that Aristophanes is practically quoting his victim’s conversation; the remark[47] about Æschylus that “he was obscure in his prologues,” is no mere rubbish attributed to a dullard. That Euripides did criticize his elder is a fact. The _Supplices_[48] contains a severe remark on the catalogue of chieftains in the _Septem_; the elaborate sarcasm directed in the _Electra_[49] against the Recognition-scene of the _Choephorœ_ is even more startling. Besides this, Aristophanes seems to quote remarks of Euripides on himself and his work: “When I first took over the art from you, I found it swollen with braggadocio and tiresome words; so the first thing I did was to train down its fat and reduce its weight”.[50] His comment on dialogue is no less pertinent: “With you Niobe and Achilles never said a word, but I left no personage idle; women, slaves, and hags all spoke”.[51] Finally, there is the perfect description of his own realism[52]: οἰκεῖα πράγματ’ εἰσάγων, οἷς χρώμεθ’, οἷς σύνεσμεν, “I introduced life as we live it, the things of our everyday experience”. Such sentences as these reflect unmistakably the conversation of a playwright who was jealous for the dignity and the progress of his art.
