But this still leaves us groping in the dark. Why did Horace declare this law? What warrant had he? What put the idea into his head? These are questions answered by a French scholar, M. Weil; in one of his ingenious and learned 'Études sur le Drame Antique,' he explains that Horace derived much of his theory of the poetic art from the Alexandrian critics, and more particularly from the writings of a certain Neoptolemus of Parium. Probably the Alexandrian authors of tragedy had been led to adopt a division into five acts by following the example of Euripides, whose practise was not uniform, but who tended to reduce to four the number of the lyric odes in his tragedies, thus separating the purely dramatic passages into five parts.

In Athens the drama had been slowly evolved out of the tragic songs; and in the surviving tragedies of Æschylus, the earliest of the three great dramatic poets of Greece, we discover that the choral odes are more abundant than the dialog which carries on the plot. In the extant plays of his mighty successor, Sophocles, the drama is seen emerging triumphant, but the lyrical passages are still frequent and important. In the later pieces of Euripides, the third and most modern of the Attic tragedians, we note that the drama has almost wholly disengaged itself from the lyric out of which it sprang. In Æschylus and in Sophocles the number of choral odes and the number of episodes, of purely dramatic passages in dialog, is never fixed, varying from play to play as the plot might demand. But in Euripides the choral odes are more detached from the drama; beautiful in themselves, they seem to exist rather for their own sake than in any integral relation to the play itself. And apparently Euripides was far more interested in his play, in his plot, and in his characters, than in these extraneous lyric passages, so he reduced them to the lowest possible number, generally to four, serving, so to speak, as exquisite interact music, separating the pathetic play into five episodes in dialog.

The Alexandrian tragedians came long after Euripides, and to their sophisticated taste his pathetic and emotional plays appealed far more than the austerer and manlier masterpieces of his two great predecessors. Apparently they accepted his form as final; they may even have left out the choruses altogether; and then their tragedies had five separate episodes—in other words, five acts. It is these lost Alexandrian tragedies, composed in the decadent days of the Greek drama, which seem to have served as the model for Seneca, the eloquent rhetorician—even tho he frequently took over the theme and often more or less of the structure of certain of the dramas of Euripides.

The tragedies of Seneca are to be considered rather as dramatic poems than as poetic dramas, since they were intended not really for performance by actors, in a theater, before an audience, but for recitation by a single elocutionist in a private house—much as a professional reader of our own time might recite unaided a more or less dramatic poem by Shelley or Byron or Browning. Coming long after Horace, Seneca unhesitatingly accepted all of the restrictions insisted upon by the Latin lyrist—including the purely academic limitation of the number of speakers taking part in any dialog to three, a limitation absolutely absurd in a poem not intended for actual acting and not forced to conform to the accidental conditions of the Attic stage. Obeying also the other rule which he found in Horace's codification of the laws of dramatic poetry, the Hispano-Roman rhetorician was careful always to cut up his play into five parts. But he saw his profit in retaining the chorus, since this could be made to serve as the appropriate mouthpiece for the elaborate passages of elocutionary splendor in which he delighted.

It is not to be wondered at that the Italian scholars of the Renascence followed the precept of Horace and the practise of Seneca. They were far more at home in Latin than they were in Greek; and they could hardly help reading into the literature of Athens what they were already familiar with in the authors of Rome. To them Seneca was as imposing as Sophocles, and Horace was almost as weighty as Aristotle. So it is that Scaliger and Minturno prescribe five acts, and that Castelvetro (always more practical in his point of view) points out that poets seem to have found the five-act form most suitable. When an Italian scholar-poet turned from criticism to creation, the tragedies he conscientiously composed obeyed all the rules, and his dramatic poems were as academic as those of Seneca, in that they were intended not for production by professional actors in a regular theater before spectators who had paid their way in, but only for an occasional performance by the author himself assisted by a few of his friends before a little group of cultivated admirers of antiquity, contemptuous of the real public. These soulless dramatic poems, devised for declamation by amateurs before a gathering of dilettants, are now perceived to be merely literary curiosities, having little connection with the real drama made for the regular theater and its myriad-minded body of playgoers.

Just as the Italian dramatic poems were imitations of Seneca, so the French dramatic poems, composed a little later, were imitations of these Italians, and also of Seneca, more or less indirectly. They were the imitations of an imitation, aping the outward form of the drama, but empty of all genuine dramatic spirit, artificial in passion and high-flown in rhetoric. And there are early English attempts at this same sort of academic tragedy, more imitative still, since we can see in them the commingled influence of the French and of the Italians immediately, and also of the remoter Seneca, whom they revered as the exemplar of true tragedy. Such a play is 'Gorboduc,' belauded by the scholarly Sidney—and even on one occasion acted, by main strength. In all of these imitations, English and French and Italian, we find the stately chorus abounding in lofty rhetoric; and we find also, and always, the division into five acts. But in the folk-theater, which the scholar-poets scorned, and out of which the living drama was to be developed, there is no trace of any division into acts. In the mysteries and the miracle-plays, and in the chronicle-plays which grew out of them, there are numberless episodes, each complete in itself, and never combined artificially into acts. The composer of any one of these folk-dramas conceived his story as a continuous narrative shown in action; and he gave no thought to the number of divisions, of episodes, of separate scenes, or of acts that it might seem to have.

III

Tragedy has ever been held to be more elevated than comedy and more worthy; and comedy has continually accepted the conditions appropriate to tragedy. Since the dignity of tragedy demanded a division into five acts, comedy was also subjected to the same rule; and this was done in spite of the fact that the plays of Plautus and Terence (composed long before Horace codified his advice to intending poets) were not divided into acts, if we may judge by the earliest of the surviving manuscripts. So it is that we find the scholarly authors of the two earliest of English comedies, 'Ralph Roister Doister' and 'Gammer Gurton's Needle,' knowing what was expected of them, and giving the five-act form to both of these amusing plays. But these two comedies, almost contemporary as they are with the academic and undramatic tragedy of 'Gorboduc,' are far superior to it in adaptability for actual performance. They are not intended only to be recited; they can be acted easily and profitably. As we analyze them we see that the structural complexity may be derived from the comic dramas of Plautus and Terence, but that the inner spirit is that of the English folk-theater, of the robust medieval farce-writers, of the unknown humorist who has left us the laughable and veracious scene of Mak and the Shepherds.

Scholars as they were, the authors of these two comedies did not scorn the primitive plays of the plain people of their own time. They did not despise the unpretending folk-drama which was then pleasing the populace; in fact, they took stock of it, and found their profit in so doing. They saw that to be raised up to the level of literature it needed only to be chastened and stiffened. They accepted the living tradition of play-making as it came down to them, and in accord with this tradition they wrought their humorous fantasies, adding the higher polish and the more adroit plot which they had learned to appreciate in the Latin comic dramatists. They accepted the native play, bare as it was, and they enriched it by bestowing on it as much as it could carry of the finer art of the Romans. Thus it is that the authors of 'Ralph Roister Doister' and of 'Gammer Gurton's Needle' may have pointed out the path of progress to the author of the 'Comedy of Errors,' whereas the authors of 'Gorboduc,' contemptuously rejecting the folk-theater of their own day, and idly copying the classicist imitations of the Italians, thereby relinquished whatever direct influence they might have had upon the growth of tragedy in England.

Both 'Ralph Roister Doister' and 'Gammer Gurton's Needle' were probably written for performance by college boys, and they have not a little of the brisk heartiness and of the broad horse-play to which we are accustomed in the college pieces of to-day. It was for performance at court that Lyly wrote the most of his plays, which lack the vivacity and the liveliness distinguishing the two college comic dramas, but which yet reveal a far better understanding of the drama than was possessed by the authors of 'Gorboduc.' Lyly again is careful to divide his plays into five acts. But his contemporaries Greene and Peele, writing solely for the professional playhouses, were bound by none of the rules which might be expected in college or at court. Whatever their own scholarly equipment, when they wrote for the professional players, they followed unhesitatingly the traditions of the contemporary theater. As playwrights they were the direct heirs of the anonymous and ignorant devisers of the medieval drama. They had a story to set on the stage; they chose a succession of more or less effective episodes, and they carelessly cast these into dialog, with little thought of form or of construction. Never do their plays contain matter enough for five full acts; and we may be certain that no such framework was ever in the mind of either of these dramatic poets. In the original editions of their pieces we find no separation into acts and scenes; and if this needless and misleading subdivision is found in later editions it is the doing of misguided editors.
