And this mimic world is capable of creating an illusion--not such as Dr Johnson combated--but of a kind he does not appear to have taken into account. The doctor is triumphant when he denies the existence of that theatrical delusion presupposed as a ground for the unities. We do not, as soon as the curtain rises, believe ourselves transported to Rome, nor do we take the actor upon his word, and believe him to be Caesar the moment he proclaims his imperial dignity. The illusion of the theatre springs directly from the _passion_ with which we are infected, not from the outward pomp and circumstance of the stage. These, even on the most ignorant of spectators, produce barely the sentiment of wonder and surprise, never a belief in their reality. The real illusion of the drama begins, so to speak, not at the beginning, but at the end; it is the last result, the result of the last vivid word which sprung from the lips of the actor; and it diffuses a momentary reality over all that stage apparatus, animate and inanimate, which was there only as a preparation for that vivid word of the poet. When the curtain rises, we see very plainly--quite unmistakeably--the boarded stage before us. It may fill with men and women most gorgeously attired, and these may proceed to declare their rank and condition, and the peculiar dangers which environ them, and still there is nothing better before us than the boarded stage and the talking actor. But, by and by, the word of passion is uttered, and the heart beats, and the wooden stage is seen no more, and the actor is forgotten in his griefs or his anger, and the fictitious position is a real life, and the pomp and circumstance of the scene, if not believed in, are no longer questioned. We are not perhaps at Rome, nor is that Mark Antony--for we never knew Mark Antony to recognise him--but this mimic world has assumed an independent life and reality of its own. When, indeed, the passion subsides, and the eloquence of the poet is mute, things revert to their matter-of-fact condition, the actor is again there, and the boards of the stage again become visible.
