With his customary shrewdness and his usual gift of piercing to the center of what he was engaged in analyzing, Aristotle more than four thousand years ago saw the necessity of a neatly articulated plot. "If you string together a set of speeches," he said, "expressive of character and well finished in point of diction and thought, you will not produce the essential tragic effect nearly so well as with a play, which, however deficient in these respects, yet has a plot and artistically constructed incidents." No broader statement than this could be made as to the all-importance of the story itself--and pantomime is a story and nothing else, a story capable of being translated by the actions of the performers, without the aid of speech. Nor need we suppose that a play without words is necessarily devoid of poetry. There may be poetry in the "set of speeches expressive of character and well finished in point of thought and diction"; but there may be poetry also in the theme itself, in the actual story. 'Romeo and Juliet,' for example, is fundamentally poetic in its theme, and it retains its poetic quality even when it is made to serve as the libretto of an opera, as it would also retain this if it should be stripped bare to be presented in pantomime. In a recent work on the 'Essentials of Poetry,' Professor William A. Neilson has made this clear: "Many a drama is a genuine poetic creation, altho it may be simple to the point of baldness in diction and exhibit the fundamental qualities of poetry only in the characterization and in the significance, proportion, and verisimilitude of the plot." That is to say, the drama can use two kinds of poetry, that which is internal and contained in the plot, and that which is external and confined to the language. It can employ jewels five-words long, That on the stretched forefinger of all Time Sparkle forever. But it can also attain poetry without the use of superb and sonorous phrases and solely by its choice of theme. This is what the poets have often felt, and as a result French lyrists, like Théophile Gautier and François Coppée, have not disdained to compose librettos for pantomimic ballets, 'Giselle' and the 'Korrigane.' One of the most successful of the recent Russian ballets was simply a representation of Gautier's poetic fantasy, 'One of Cleopatra's Nights,' II
