This art of preparation belongs, of course, to the modern stage as much as to the ancient, or more. So do the similar arts of making the right juncture between scenes, of arranging the contrasts and clashes, and especially of so ending each scene as to make the spectator look eagerly for the next move. He must be given just enough notion of the future to whet his appetite; not enough to satisfy it. These are general rules that apply to all good drama. They can all be studied in Mr. Archer's book, Play-Making: A Manual of Craftsmanship. In ancient times they were more developed by Euripides than by his predecessors, but that is all we need say.

Prologue; Set Speech; Messenger; there still remain two stumbling-blocks to a modern reader of Greek tragedies, the Deus ex Mâchinâ, (or "God from the Machine") and the Chorus.

About the appearance of the god we need say little. We have seen above that an epiphany of some Divine Being or a Resurrection of some dead Hero seems to have been an integral part of the old ritual and thus has its natural place in tragedy. His special duty is to bring the action to a quiet close and to ordain the ritual on which the tragedy is based—thus making the performance itself a fulfilment of the god's command (see above p. 66). The actual history of this epiphany is curious. As far as our defective evidence allows us to draw conclusions we can make out that Aeschylus habitually used a divine epiphany, but that he generally kept it for the last play of a trilogy; that he often had a whole galaxy of gods, and that, with some exceptions, his gods walked the floor of earth with the other actors. (The evidence for this is given in Miss Harrison's Themis, pp. 347 ff.) Sophocles, moving towards a more "natural" and less ritual tragedy, used the divine epiphany comparatively little. Euripides, somewhat curiously for one so hostile to the current mythology, intensified this ritual element in drama as he did all the others. And he used it more and more as he grew older. He evidently liked it for its own sake.

There is one view about the Deus ex Mâchinâ which needs a word of correction. It is widely entertained and comes chiefly from Horace's Ars Poetica. It takes the Deus as a device—and a very unskilful one—for somehow finishing a story that has got into a hopeless tangle. The poet is supposed to have piled up ingenious complications and troubles until he cannot see any way out and has to cut the knot by the intervention of something miraculous—in this case, of a machine-made god. Now devices of this sort—the sudden appearance of rich uncles, the discovery of new wills, or of infants changed at birth and the like—are more or less common weaknesses in romantic literature. Hence it was natural that Horace's view about Euripides's god should be uncritically accepted. But as a matter of fact it is a mere mistake. It never in any single case holds good—not even in the Orestes. And there are some plays, like the Iphigenîa in Tauris, in which, so far from the god coming to clear up a tangled plot, the plot has to be diverted at the last moment so as to provide an excuse for the god's arrival. Euripides evidently liked a supernatural ending, and when he had to do without a real god—as in the Medea and the Hecuba—he was apt to end with winged chariots and prophecies. Can we in the least understand what he gained by it?

We must remember one or two things. The epiphany was in the ritual. It was no new invention in itself; the only new thing, apparently, was an improved piece of stage machinery enabling the god to appear more effectively. Further, if we try to put ourselves into the minds of fifth century Greeks, there was probably nothing absurd, nothing even unlikely, in supposing the visible appearance of a god in such an atmosphere as that of tragedy. The heroes and heroines of tragedy were themselves almost divine; they were all figures in the great heroic saga and almost all of them—the evidence is clear—received actual worship. If Orestes or Agamemnon is present on the stage, it is not surprising that Apollo should appear to them. It is, I think, chiefly due to the mistake of over-emphasizing the realism of Euripides that recent writers—myself at one time included—have been so much troubled over these divine epiphanies.

I suspect, also, that we are troubled by a difference of convention about the way in which supernatural beings ought to speak. We moderns like them to be abrupt, thunderous, wrapped in mystery. We expect the style of ancient Hebrew or Norse poetry. Probably a Greek would think both barbaric. At any rate the Greek gods, both in Euripides and elsewhere, affect a specially smooth and fluent and lucid utterance.

And apart from the artistic convention there is a historical consideration which we must never forget, though we are constantly tempted to do so. A well-educated Athenian of the fifth century before Christ was, after all, not as securely lifted above what he called "primaeval simplicity" as a similar man in Western Europe in the eighteenth or nineteenth century after. He was just beginning, with great daring and brilliance, to grasp at something like a philosophic or scientific view of the world; but his hold was very precarious and partial, and when it slipped he fell unsuspectingly into strange abysses. A visible god in the theatre laid probably no more strain on his credulity than, say, a prophetic dream on ours.

However, the above considerations are only pleas in mitigation of sentence. They tend to show that the Deus ex Mâchinâ was not in itself ridiculous to the contemporaries of Euripides; we must go further and try to see why he liked it. The best way is simply, with our antecedent prejudices removed, to read and re-read some of the best epiphany scenes; those, for instance, which close the Electra, the Hippolytus, the Rhesus or the Andromache. We have already seen in the Electra how the poet can use his gods for delivering his essential moral judgment on the story; the condemnation of revenge, the pity for mankind, the opening up of a larger atmosphere in which the horror through which we have just passed falls into its due resting-place. In the Hippolytus the sheer beauty of the Artemis scene speaks for itself and makes a marvellous ending. Notably it attains an effect which could scarcely be reached in any other way, a strange poignant note amid the beauty, where mortal emotion breaks against the cliffs of immortal calm. After many words of tenderness Artemis finishes (1437 ff.):

Farewell! I may not watch man's fleeting breath, Nor stain mine eyes with the effluence of death. And sure that terror now is very near. . . . (The Goddess slowly rises and floats away.)
