IN discussing the modern production of it is unnecessary to go beyond Wagner. Wagner, who left nothing as he found it, not only started the producers upon a new career, he also provided them with a philosophy which purported to raise a respectable handicraft to the level of a deep, hieratic mystery. We find in Wagner's Opera and Drama a clearer suggestion of that shadow-show towards which Mr. Gordon-Craig is now groping than is contained in any of the modern books. In stage-craft, as in music and song, Wagner, who simply sets out to prove that his own dramas were the only possible dramas, proved more than he was aware of. His deep discussion of the function of gesture and stage representation in opera still remains the most convenient point from which to approach the most modern developments. Opera and Drama is perhaps the greatest piece of special pleading in literature. Those critics who have been content to exclaim against its portentous, hopeless and needless difficultywho see in Wagner's prose works little more than a deplorable evidence of the author's pugnacity and conceit-have chosen to deny themselves much light and wisdom. It is true that, if Wagner's operas were destroyed, Wagner's prose works would be unintelligible. But the difficulty of Wagner's prose works almost disappears if we read them as foot-notes and prefaces to his musicdramas. Wagner's prose works in every line and paragraph have a direct bearing upon his own practise. The vast and general statements which sprawl across his pages seemingly without system-statements which to the casual reader are formless and vague-become quite definite and clear when we remember that Wagner is writing, not a self-supporting thesis as he cunningly pretends, but an apt and strictly pertinent defence of some particular musical or literary habit of his own. Wagner in his writings upon is vague and general, and leaves out all the instances which might clinch his propositions, because he is thinking always of his own works-of a passage in Tristan or Siegfried-and does not realise that the general reader is usually a less complete Wagnerian than Wagner. Besides, it would
