It may be doubted also whether not a few dramatists, writing later than Shakspere, would not have done well to claim the liberty he and Lope de Vega chose to exercise at will. Racine, for one, had sadly to stretch his 'Athalie' to fill out the five-act framework which he had blindly accepted, altho he had earlier limited 'Esther' to three acts. Schiller, for another, would have gained a swifter compactness for his play if he had left out the needless fifth act of his 'William Tell' and rolled his fourth act into his third. Victor Hugo had to manufacture a fourth act for his 'Ruy Blas,' so slightly related to his main story that it was cut out of the English adaptation acted by Fechter and Booth. Ibsen, it may be added, composed his first tragedy, 'Catiline,' in three acts, altho it was in blank verse, thus early revealing his characteristic independence of tradition. (1907.) P. S.--Since this paper was written I have found two opinions as to the number of acts a play ought to have which were unknown to me when I undertook the discussion. The first is in the 'Dasarupa,' the Hindu treatise on the craft of play-making: "There are five stages of the action which is set on foot by those that strive after a result: Beginning, Effort, Prospect of Success, Certainty of Success, Attainment of the Result." The second is in the commentary made by Robert Louis Stevenson during his methodical perusal of the dramas of the elder Dumas. After reading 'Henri III et sa Cour,' Stevenson declares that here in Dumas's first piece "is the cloven foot; a fourth act that has no part or lot in the play; a fourth act that is a mere incubus and interruption--that takes the eye off the action, and between two spirited and palpitating scenes interjects a damned sermon on the history of France. Poor Tribonian had a sore job to make up the fifty books of the Pandects; what was that to the labor of a dramatist bent on filling his five acts? I go as far as this: the natural division of the normal play is four: Act I, exposition; Act II, the problem produced; Act III, the problem argued; Act IV, the way out of it." (1916.)
