Freytag had no doubt at all as to the necessity of the division into five acts. He received it with blind faith, as tho it had been prescribed by divine authority. Yet if he had chosen to explore the early history of the drama in his own tongue, he would have found Hans Sachs sometimes extending his plays into six acts, and even into seven. And if he had cared to consider the drama of the Spaniards he would have seen that the most of the plays of Calderon are in three acts--a division which the great dramatic poet of Spain had taken over, as he had taken over so much else, from his masterful predecessor, Lope de Vega. In his interesting and illuminating little treatise on the art of writing plays, Lope de Vega gave the credit of establishing the three-act form to Virues. Plays had previously been written in four acts; as Lope puts it pleasantly: "The drama had gone on all fours, like a child, and truly it was then in its infancy." Freytag ignored or was ignorant of Hans Sachs and Calderon. His mind was fixed on Goethe and on Schiller, altho his vision also included Shakspere, upon whom the two German poets had more or less modeled themselves. The tradition of the five-act form might not obtain in the earliest German drama, as it did not obtain in the Spanish; but it was firmly established in the later German drama, in the English, and in the French. It is easy to see that the later Germans derived it from the French and the English; but where did the French and the English get it? Where could they get it? No such division existed in the medieval drama, in the mysteries and in the miracle-plays, out of which the drama of every modern language has been developed. No such division existed in the Greek drama, which has served as a standard and as a stimulus to the drama of every modern literature. A Greek tragedy was represented without any intermission in a single, long unbroken act; and if a sequence of three plays was sometimes performed, one after another, on the same day, and dealing with successive periods of the same story, this trilogy might suggest a division into three parts. Nor is any hint of the duty of dividing a tragedy into five parts to be discovered anywhere in Aristotle. II And yet we must go back to the Greek theater if we want to see why it is that the 'Femmes Savantes' of Molière and the 'School for Scandal' of Sheridan are each of them in five acts. But it is not from a Greek that we get the law that this division was obligatory on all self-respecting dramatists; it is from a Roman, writing at a time when the drama of his own language had been ousted from the stage by pantomimic spectacle and by gladiatorial combat. It is Horace, who, in his epistle on the art of poetry, declares the necessity of five acts: Ne brevior, neu sit quinto productior actu Fabula quae posci vult et spectata reponi.
