Every one must in particular admit the justness of Addison's views respecting the incongruity of operatic scenery; indeed, his observations on that subject might with advantage be republished now and then in the present day. "What a field of raillery," he says, "would they [the wits of King Charles's time] have been let into had they been entertained with painted dragons spitting wildfire, enchanted chariots drawn by Flanders mares, and real cascades in artificial landscapes! A little skill in criticism would inform us, that shadows and realities ought not to be mixed together in the same piece; and that the scenes which are designed as the representations of nature should be filled with resemblances, and not with the things themselves. If one would represent a wide champaign country, filled with herds and flocks, it would be ridiculous to draw the country only upon the scenes, and to crowd several parts of the stage with sheep and oxen. This is joining together inconsistencies, and making the decoration partly real and partly imaginary. I would recommend what I have here said to the directors as well as the admirers, of our modern opera." In the matter of stage decoration we have "learned nothing and forgotten nothing" since the beginning of the 18th century. Servandoni, at the theatre of the Tuileries, which contained some seven thousand persons, introduced as elaborate and successful mechanical devices as any that have been known since his time; but then as now the real and artificial were mixed together, by which the general picture is necessarily rendered absurd, or rather no general picture is produced. Independently of the fact that the reality of the natural objects makes the artificiality of the manufactured ones unnecessarily evident as when the branches of real trees are agitated by a gust of wind, while those of pasteboard trees remain fixed--it is difficult in making use of natural objects on the stage to observe with any accuracy the laws of proportion and perspective, so that to the eye the realities of which the manager is so proud, are, after all, strikingly unreal. The peculiar conditions too, under which theatrical scenery is viewed, should always be taken into account. Thus, "real water," which used at one time to be announced as such a great attraction at some of our minor playhouses, does not look like water on the stage, but has a dull, black, inky, appearance, quite sufficient to render it improbable that any despondent heroine, whatever her misfortune, would consent to drown herself in it. The most contemptuous thing ever written against the Opera, or rather against music in general, is Swift's celebrated epigram on the Handel and Buononcini disputes:-- "Some say that Signor Buononcini Compared to Handel is a ninny; While others say that to him, Handel Is hardly fit to hold a candle. Strange that such difference should be, 'Twixt Tweedledum and Tweedledee."
