Corneille with great reason finds the rule extremely inconvenient; he therefore prefers the more lenient interpretation, and says, "he would not scruple to extend the duration of the action even to thirty hours." Others, however, most rigorously insist on the principle that the action should not occupy a longer period than that of its representation, that is to say, from two to three hours.—The dramatic poet must, according to them, be punctual to his hour. In the main, the latter plead a sounder cause than the more lenient critics. For the only ground of the rule is the observation of a probability which they suppose to be necessary for illusion, namely, that the actual time and that of the representation should be the same. If once a discrepancy be allowed, such as the difference between two hours and thirty, we may upon the same principle go much farther. This idea of illusion has occasioned great errors in the theory of art. By this term there has often been understood the unwittingly erroneous belief that the represented action is reality. In that case the terrors of Tragedy would be a true torture to us, they would be like an Alpine load on the fancy. No, the theatrical as well as every other poetical illusion, is a waking dream, to which we voluntarily surrender ourselves. To produce it, the poet and actors must powerfully agitate the mind, and the probabilities of calculation do not in the least contribute towards it. This demand of literal deception, pushed to the extreme, would make all poetic form impossible; for we know well that the mythological and historical persons did not speak our language, that impassioned grief does not express itself in verse, &c. What an unpoetical spectator were he who, instead of following the incidents with his sympathy, should, like a gaoler, with watch or hour-glass in hand, count out to the heroes of the tragedy, the minutes which they still have to live and act! Is our soul then a piece of clock-work, that tells the hours and minutes with infallible accuracy? Has it not rather very different measures of time for agreeable occupation and for wearisomeness? In the one case, under an easy and varied activity, the hours fly apace; in the other, while we feel all our mental powers clogged and impeded, they are stretched out to an immeasurable length. Thus it is during the present, but in memory quite the reverse: the interval of dull and empty uniformity vanishes in a moment; while that which marks an abundance of varied impressions grows and widens in the same proportion. Our body is subjected to external astronomical time, because the organical operations are regulated by it; but our mind has its own ideal time, which is no other but the consciousness of the progressive development of our beings. In this measure of time the intervals of an indifferent inactivity pass for nothing, and two important moments, though they lie years apart, link themselves immediately to each other. Thus, when we have been intensely engaged with any matter before we fell asleep, we often resume the very same train of thought the instant we awake and the intervening dreams vanish into their unsubstantial obscurity. It is the same with dramatic exhibition: our imagination overleaps with ease the times which are presupposed and intimated, but which are omitted because nothing important takes place in them; it dwells solely on the decisive moments placed before it, by the compression of which the poet gives wings to the lazy course of days and hours.

But, it will be objected, the ancient tragedians at least observed the Unity of Time. This expression is by no means precise; it should at least be the identity of the imaginary with the material time. But even then it does not apply to the ancients: what they observe is nothing but the seeming continuity of time. It is of importance to attend to this distinction—the seeming; for they unquestionably allow much more to take place during the choral songs than could really happen within their actual duration. Thus the Agamemnon of Aeschylus comprises the whole interval, from the destruction of Troy to his arrival in Mycenae, which, it is plain, must have consisted of a very considerable number of days; in the Trachiniae of Sophocles, during the course of the play, the voyage from Thessaly to Euboea is thrice performed; and again, in the Supplices of Euripides, during a single choral one, the entire march of an army from Athens to Thebes is supposed to take place, a battle to be fought, and the General to return victorious. So far were the Greeks from this sort of minute and painful calculations! They had, however, a particular reason for observing the seeming continuity of time in the constant presence of the Chorus. When the Chorus leaves the stage, the continuous progress is interrupted; of this we have a striking instance in the Eumenides of Aeschylus, where the whole interval is omitted which was necessary to allow Orestes to proceed from Delphi to Athens. Moreover, between the three pieces of a trilogy, which were acted consecutively, and were intended to constitute a whole, there were saps of time as considerable as those between the three acts of many a Spanish drama.

The moderns have, in the division of their plays into acts, which, properly speaking, were unknown to Greek Tragedy, a convenient means of extending the period of representation without any ill effect. For the poet may fairly reckon so far on the spectator's imagination as to presume that during the entire suspension of the representation, he will readily conceive a much longer interval to have elapsed than that which is measured by the rhythmical time of the music between the acts; otherwise to make it appear the more natural to him, it might be as well to invite him to come and see the next act to-morrow. The division into acts had its origin with the New Comedy, in consequence of the exclusion of the chorus. Horace prescribes the condition of a regular play, that it should have neither more nor less than five acts. The rule is so unessential, that Wieland thought Horace was here laughing at the young Pisos in urging a precept like this with such solemnity of tone as if it were really of importance. If in the ancient Tragedy we may mark it as the conclusion of an act wherever the stage remains empty, and the chorus is left alone to proceed with its dance and ode, we shall often have fewer than five acts, but often also more than five. As an observation that in a representation, between two or three hours long, such a number of rests are necessary for the attention, it may be allowed to pass. But, considered in any other light, I should like to hear a reason for it, grounded on the nature of Dramatic Poetry, why a drama must have so many and only so many divisions. But the world is governed by prescription and tradition: a smaller number of acts has been tolerated; to transgress the consecrated number of five [Footnote: Three unities, five acts: why not seven persons? These rules seem to proceed according to odd numbers.] is still considered a dangerous and atrocious profanation.

As a general rule, the division into acts seems to me erroneous, when, as is so often the case in modern plays, nothing takes place in the intervals between them, and when the persons at the beginning of the new act are exhibited in exactly the same situation as at the close of the foregoing one. And yet this stand-still has given much less offence than the assumption of a considerable interval, or of incidents omitted in the representation, because the former is merely a negative error.

The romantic poets take the liberty even of changing the scene during the course of an act. As the stage is always previously left empty, these also are such interruptions of the continuity, as would warrant them in the assumption of as many intervals. If we stumble at this, but admit the propriety of a division into acts, we have only to consider these changes of scene in the light of a greater number of short acts. But then, it will perhaps be objected, this is but justifying one error by another, the violation of the Unity of Time by the violation of the Unity of Place: we shall, therefore, proceed to examine more at length how far the last- mentioned rule is indispensable.

In vain, as we have already said, shall we look to Aristotle for any opinion on this subject. It is asserted that the rule was observed by the ancients. Not always, only generally. Of seven plays by Aeschylus, and the same number by Sophocles, there are two, the Eumenides and the Ajax, in which the scene is changed. That they generally retain the same scene follows naturally from the constant presence of the chorus, which must be got rid of by some suitable device before there can be a change of place. And then, again, it must not be forgotten, that their scene represented a much wider extent than in most cases ours does; not a mere room, but the open space before several buildings: and the disclosing the interior of a house by means of the encyclema, may be considered in the same light as the drawing a back curtain on our stage.

The objection to the change of scene is founded on the same erroneous idea of illusion which we have already discussed. To transfer the action to another place would, it is urged, dispel the illusion. But now if we are in reality to consider the imaginary for the actual place, then must stage decoration and scenery be altogether different from what it now is. [Footnote: It is calculated merely for a single point of view: seen from every other point, the broken lines betray the imperfection of the imitation. Even as to the architectural import, so little attention do the audience in general pay to these niceties, that they are not even shocked when the actors enter and disappear through a wall without a door, between the side scenes.] Johnson, a critic who, in general, is an advocate for the strict rules, very justly observes, that if our imagination once goes the length of transporting us eighteen hundred years back to Alexandria, in order to figure to ourselves the story of Antony and Cleopatra as actually taking place before us, the next step, of transporting ourselves from Alexandria to Rome, is easier. The capability of our mind to fly in thought, with the rapidity of lightning, through the immensity of time and space, is well known and acknowledged in common life; and shall poetry, whose very purpose it is to add all manner of wings to our mind, and which has at command all the magic of genuine illusion, that is, of a lively and enrapturing fiction, be alone compelled to renounce this universal prerogative?

Voltaire wishes to derive the Unity of Place and Time from the Unity of Action, but his reasoning is shallow in the extreme. "For the same reason," says he, "the Unity of Place is essential, because no one action can go on in several places at once." But still, as we have already seen, several persons necessarily take part in the one principal action, since it consists of a plurality of subordinate actions, and what should hinder these from proceeding in different places at the same time? Is not the same war frequently carried on simultaneously in Europe and India; and must not the historian recount alike in his narrative the events which take place on both these scenes?

"The Unity of Time," he adds, "is naturally connected with the two first. If the poet represents a conspiracy, and extends the action to fourteen days, he must account to me for all that takes place in these fourteen days." Yes, for all that belongs to the matter in hand; all the rest, being extraneous to it, he passes over in silence, as every good storyteller would, and no person ever thinks of the omission. "If, therefore, he places before me the events of fourteen days, this gives at least fourteen different actions, however small they may be." No doubt, if the poet were so unskilful as to wind off the fourteen days one after another with visible precision; if day and night are just so often to come and go and the characters to go to bed and get up again just so many times. But the clever poet thrusts into the background all the intervals which are connected with no perceptible progress in the action, and in his picture annihilates all the pauses of absolute stand-still, and contrives, though with a rapid touch, to convey an accurate idea of the period supposed to have elapsed. But why is the privilege of adopting a much wider space between the two extremes of the piece than the material time of the representation important to the dramatist, and even indispensable to him in many subjects? The example of a conspiracy given by Voltaire comes in here very opportunely.

A conspiracy plotted and executed in two hours is, in the first place, an incredible thing. Moreover, with reference to the characters of the personages of the piece, such a plot is very different from one in which the conceived purpose, however dangerous, is silently persevered in by all the parties for a considerable time. Though the poet does not admit this lapse of time into his exhibition immediately, in the midst of the characters, as in a mirror, he gives us as it were a perspective view of it. In this sort of perspective Shakspeare is the greatest master I know: a single word frequently opens to view an almost interminable vista of antecedent states of mind. Confined within the narrow limits of time, the poet is in many subjects obliged to mutilate the action, by beginning close to the last decisive stroke, or else he is under the necessity of unsuitably hurrying on its progress: on either supposition he must reduce within petty dimensions the grand picture of a strong purpose, which is no momentary ebullition, but a firm resolve undauntedly maintained in the midst of all external vicissitudes, till the time is ripe for its execution. It is no longer what Shakspeare has so often painted, and what he has described in the following lines:—
