Care, of course, is needed in regard to the employment of properties also on the stage. The difficulty of placing a horse upon the stage is well known. He cannot be made a part of the picture, cannot be subordinated, or "made up." If we observe from the gallery when a horse is on the stage, we find that the attention of everybody is centred upon him, and the point of the play is lost. Who ever receives an impression of the splendid music while Brunhilde stands holding by the bridle a great cart-horse?
The centre of interest in Goldsmith's "She Stoops to Conquer" is not in the horse that Tony Lumpkin has been driving, but in his dialogue with his mother, and her fright at her husband, whom she believes to be a highwayman. To introduce two horses, making the audience uneasy as to what they will do, destroys the dramatic interest of the scene.
The bringing of real horses on the stage in a play always causes fear of an accident and distracts attention from the real point of the scene. To see a noted singer motioning to a super to bring her horse on the stage makes "the judicious grieve." There is no doubt a tendency at the present time to over-elaboration and to extravagance in realistic presentation. But if too much literalism is objectionable in the play, how much more is it in the monologue?
All these principles may be combined in one, the law of harmony. This is possibly the simplest law regarding properties, dialect, and all accidentals in the interpretation of a monologue. The degree of realism in one direction or in one part must be justified by corresponding degrees in others. All art is relative, and depends upon the unity of impression.
A man's clothes may be a part of his character, and a singular individual often has an odd hat, or cane, that has become an essential means in the expression of his character. Where a man uses a stick habitually in an individual way, the dramatic artist may use this to a certain extent, especially in monologues of a lower type. So of any article of dress; when an essential part of a character is needed for expression, it is proper to use it. The same principle applies here that was shown in the case of dialect. Though accidental, an article of dress may become a means of expression. In the higher and more exalted monologues, however, there should be more suggestion and less literal presentation of properties or adjuncts. The sublimer the literature, the more appeal is made to the imagination; the deeper the feeling, the more complete is the dependence upon the imagination of the audience. The more lyrical also, a monologue, the less must there be of any accidental representation. This is sure to destroy the lyric spirit. Even when there is not a lyric element the dramatic element is only suggested, and in the sublimest monologues often verges towards the epic. The monologue is rarely purely dramatic, that is, dramatic in a sense peculiar to the theatre.
