Drama is a reading of human life: if it is to hold one's interest it must deal with the feelings, thought, and action of genuine human beings and represent their complex interaction: the characters must be real and must differ one from the other, so that by force of contrast and by the continued play of diverse aspects and developments of the human soul, the significance, the pathos, and the power of the fragment of human life selected for representation may be fully brought out and set before our eyes. If these characteristics be absent, the drama must of necessity be an artistic failure by reason of its lack of truth. But it requires also plot, with a logical growth leading to some great climax and developing a growing suspense in the spectator as to what shall be the end. It is true that plot without reality may give us a successful melodrama, that truth of character-drawing with a minimum of plot may move and interest us. But in neither case shall we have drama in its truest and noblest form. Seneca gives us neither the half nor the whole. The stage is ultimately the touchstone of dramatic excellence. But if it is to be such a touchstone, it must have an audience with a penetration of intelligence and a soundness of taste such as had long ceased to characterize Roman audiences. The Senecan drama has lost touch with the stage and lacks both unity and life. Such superficial unity as his plots possess is due to the fact that they are ultimately imitations of Greek[176] drama. A full discussion of the plots is neither necessary here nor possible. A few instances of Seneca's treatment of his material must suffice.[177] He has no sense of logical development; the lack of sequence and of proportion traceable in the letters is more painfully evident in the tragedies. The _Hercules Furens_ supplies an excellent example of the weakness of the Senecan plot. It is based on the [Greek: H_erakl_es mainomenos] of Euripides, and such unity as it possesses is in the main due to that fact. It is in his chief divergences from the Euripidean treatment of the story that his deficiencies become most apparent. Theseus appears early in the play merely that he may deliver a long rhodomontade on the appearance of the underworld, whence Hercules has rescued him; and, worst of all, the return of Hercules is rendered wholly ineffective. Amphitryon hears the approaching steps of Hercules as he bursts his way to the upper world and cries (523)-- est est sonitus Herculei gradus. The chorus then, as if they had heard nothing, deliver themselves of a chant that describes Hercules as still a prisoner in Hades. When Hercules at last is allowed to appear, he appears alone, and delivers a long ranting glorification of himself (592-617) before he is joined by his father, wife, and children. As Leo has remarked,[178] this episode has been tastelessly torn into two fragments merely to give Hercules an opportunity for turgid declamation.
