In our own day when every dramatist is compelled to create a new plot it is easy to underestimate the originality of men like the Greek Euripides, the Roman Accius, the French Racine, the English Shakespeare, who all in varying degrees were satisfied to use old plots, even old plays, and to give all their attention to a personal and original interpretation of the inner meaning of a familiar story and of the motives that impelled the characters. We may illustrate the old method of procedure by examining Seneca’s _Medea_, since here we have a complete Latin play which shows what even an uninspired Roman dramatist might do by way of re-reading an ancient legend. Medea in the old unvarnished myth of the barbaric age was apparently a bundle of natural passions, a savage creature gifted with superhuman powers. Jason owed her his life, but since a Greek prince could hardly wed a barbarian and make her his queen, he might reasonably, according to Greek standards, abandon her when his “higher” duties to state and position demanded it. In a rage of jealous hate, the creature might then wreak her vengeance upon Jason and Jason’s children. Such action was quite comprehensible to the semibarbarous age that shaped the myth, but not to the more humane Athenians of Euripides’ day. The Greek dramatist, accordingly, had offered a new explanation of the problem. In his version Jason has disregarded the higher demands of humanity for a selfish passion or a more selfish ambition. Medea, the woman, has been infinitely wronged, and in her helplessness—it is not all jealousy and hate—she slays her children to save them from a worse fate. But to the Roman even this interpretation seems impossible, and the character of Jason least comprehensible of all. A Roman nobleman could not so abandon his sons, and the woman, if she was indeed human, could not slay her children either in hate or in love. Seneca, therefore, while keeping the main plot, seeks a new explanation for the woman’s act. Medea is again painted as the barbaric witch that she was before Euripides transformed her. Jason marries Creusa for the sake of his children—a wholly comprehensible act to a Roman of Nero’s day—and the uncontrollable Medea is driven into a rage that does not hesitate to commit murder. But, however jealous she might have been, Seneca feels that she could not have laid hands upon her own offspring. Yet the tale said that she did. Seneca’s solution of the dilemma is simple. Woe has driven Medea insane and the ghost of her brother hovers before her, a symbol of that insanity. Accordingly, it is in a fit of madness that she does the deed. In Seneca, as in Euripides, the action follows the ancient myth, but the interpretation of that myth varies with the author, and in both cases this reinterpretation is not so much an invention of the dramatist as a reflection of the changed point of view of the society of his time. The moderns have, of course, felt the same need for a re-reading of
