Aristophanes was so far from being blind to the poetical merits of Euripides, that he was himself charged by his rivals with borrowing from him, and in one of his lost plays acknowledged that in his diction he had imitated the terseness of the tragic poet, but asserted that his thoughts were less vulgar. How accurately he had studied the works of the tragic drama, how vividly he perceived the genuine character of Greek tragedy, and the peculiar genius of each poet, is sufficiently proved by the mode in which he has conducted the contest which he feigns between Æschylus and Euripides. But his criticism would probably have been less severe, if he had not considered Euripides less in his poetical character than in his connection with the sophistical school. Euripides had in fact been a hearer of Anaxagoras, and probably both of Protagoras and Prodicus. In his house Protagoras was said to have read one of his works by which he incurred a charge of atheism. He was also on intimate terms with Socrates, who was therefore reported to have aided him in the composition of his tragedies, and perhaps may have done so, in the same way as Prodicus and Anaxagoras; and this connection was, as we shall see, of itself a sufficient ground with Aristophanes for suspicion and aversion. The strength of Euripides lay in passionate and moving scenes, and he sought like other poets for situations and characters which afforded the best opportunity for the display of his powers. But he was too frequently tempted to work upon the feelings of his audience by an exhibition of sufferings which were quite foreign to the heroic dignity of the persons who endured them, who were therefore degraded by the pity they excited. The misery of his heroes often consisted chiefly in bodily privations, which could only awaken the sympathy of the spectator’s animal nature. His irreligion is contrasted with the piety of Æschylus, who invokes the goddess of the Eleusinian mysteries; a hint which, after the prosecution of Alcibiades, was easily understood, as to the party to which Euripides belonged. It was probably in the same point of view that Aristophanes considered the plays which he founded on tales of criminal passion.
